METHODS FOR TREATING INNER LINERS, INNER LINERS RESULTING THEREFROM AND TIRES CONTAINING SUCH INNER LINERS

FIELD

The present application is directed to methods for treating a cured inner liner; to treated, cured inner liners resulting from such methods; and to tires containing the treated inner liners.

BACKGROUND

When an uncured tire is placed into a tire mold for curing, the radially innermost component of the tire is often the inner liner. During the curing process that takes place in the tire mold, a bladder is inflated and presses against the radially inward-facing surface of the inner liner (the lower surface of the inner liner). In order to prevent sticking (or co-curing) of the lower surface of the inner liner to the bladder, a polysiloxane-containing release may be applied to the lower surface of inner liner (prior to the tire body being placed into the tire mold). While the polysiloxane-containing release provides the advantage of preventing sticking of the inner liner surface to the bladder in the tire mold, it is disadvantageous after the cured tire is removed from the mold because it remains upon the lower surface of the cured inner liner (as part of the rubber) and inhibits adhesion of other materials to the lower surface. Alternatively, some tires are manufactured without the lower surface of their inner liner being treated with a polysiloxane-containing release. Regardless of whether the inner liner has been release treated, after a tire having a cured inner liner is removed from a tire mold, the manufacturer may desire to install one or more components radially inward of the inner liner. Exemplary such components include noise barriers (e.g., foam noise barriers), an air barrier layer, a sealant layer, a run-flat insert, or an electronic communication module. These components may be positioned securely against the lower surface of the inner liner using an adhesive.

In a second embodiment, a treated, cured inner liner is disclosed.

Definitions

The terminology as set forth herein is for description of the embodiments only and should not be construed as limiting the invention as a whole.

As used herein, the term “majority” means more than 50% (e.g., 50.5%, 51%, 60%, etc.) and may encompass 100%.

As used herein, the term “natural rubber” means naturally occurring rubber such as can be harvested from sources such as Hevea rubber trees and non-Hevea sources (e.g., guayule shrubs and dandelions such as TKS). In other words, the term “natural rubber” should be construed so as to exclude synthetic polyisoprene.

As used herein, the term “phr” means parts per one hundred parts rubber. In certain embodiments, the 100 parts rubber should be understood to refer to 100 parts of the at least one diene monomer-containing rubber. 100 parts of rubber may also be referred to as 100 phr.

As used herein the term “polyisoprene” means synthetic polyisoprene. In other words, the term is used to indicate a polymer that is manufactured from isoprene monomers, and should not be construed as including naturally occurring rubber (e.g., Hevea natural rubber, guayule-sourced natural rubber, or dandelion-sourced natural rubber). However, the term polyisoprene should be construed as including polyisoprenes manufactured from natural sources of isoprene monomer.

As used herein the term “radially inward” is a relative term indicating that a component is positioned or arranged closer to or facing the inner portion of a tire, with the understanding that the road-contacting tread is generally the radially outermost portion of a tire. As a non-limiting example, body plies within a tire are positioned radially inward of the road-contacting tread of the tire.

Treated, Cured Inner Liner

As discussed above, the methods of the first and third embodiments disclosed herein include treating the surface of a cured inner liner, more specifically the lower surface of the cured inner liner. Additionally, the third and fourth embodiments disclosed herein also pertain to a cured inner liner (and a tire comprising a cured inner liner) which comprises rubber, a majority by weight of which comprises butyl rubber (optionally halogenated) and has an upper surface and a lower surface with a rubber-containing film upon the lower surface; in certain embodiments of the third and fourth embodiments, the rubber-containing film can be understood as resulting from a method according to the first or third embodiments disclosed herein. The cured inner liner refers to the cured version of an inner liner which generally is cured in a tire mold as part of the tire making process. The lower surface of the cured inner liner refers to the surface that will face radially inward when the inner liner is incorporated into a tire. According to the methods of the first and third embodiments, the cured inner liner that is provided may be part of a tire and the lower surface of the inner liner (or cured inner liner) refers to the surface that will be radially inward facing when the inner liner is contained within a tire. As discussed in more detail infra the methods of the first and third embodiments produce a rubber-containing film upon the lower surface of the cured inner liner by applying a rubber-containing liquid and allowing it to dry. Similarly, the cured inner liner (and tire comprising a cured inner liner) according to the second and fourth embodiments disclosed herein also include a rubber-containing film upon the lower surface of the cured inner liner.

In certain embodiments of the first and third embodiments, the cured inner liner that has its lower surface treated with the rubber-containing liquid has had its lower surface pre-treated with a release treatment comprising polysiloxane-moieties. In certain embodiments of the first and third embodiments, the cured inner liner comprising rubber, a majority of which comprises butyl rubber (optionally halogenated) wherein the cured inner liner has an upper and a lower surface, has a lower surface further comprising a release treatment comprising polysiloxane moieties. Such a release treatment allows for a tire body containing the release treatment upon the lower surface of its inner liner to be cured in a tire mold and pressed against a curing bladder without sticking or co-curing of the inner liner's lower surface to the curing bladder. Similarly, in certain embodiments of the second and fourth embodiments, the cured inner liner with a lower surface including (comprising) a rubber-containing film is a cured inner liner which comprises polysiloxane moieties within its lower surface. As discussed in more detail below, when the lower surface of the cured inner liner upon which the rubber-containing film is produced (or upon which the rubber-containing film exists) comprises a release treatment comprising polysiloxane moieties, treatment with the rubber-containing liquid and drying of that rubber-containing liquid produces a rubber-containing film without adhesive properties. In other words, the rubber-containing film is non-adhesive. In certain embodiments of the first-fourth embodiments, a rubber-containing film that is non-adhesive may also be considered to be an adhesion film which increases the adherability of the lower surface of the cured inner liner. By adherability is meant the ability of other materials to adhere to the lower surface of the cured inner liner. Preferably, the non-adhesive film or adhesion film is capable of having a separate adhesive (e.g., a PSA) adhered to it. Notably, when the lower surface of the cured inner liner comprises a release treatment comprising polysiloxane moieties (i.e., prior to treatment with the rubber-containing liquid), the lower surface is not capable of having a separate adhesive (e.g., a PSA) adhere to it. Thus, in such embodiments, the rubber-containing film produced by the methods of the first and third embodiments disclosed herein as well as the rubber-containing film according to the second and fourth embodiment can be understood as improving the adherability of the lower surface of the cured inner liner.

As used herein, a polysiloxane moiety refers to the structure I, as follows: —[Si—O]_x—. Thus, by referring to polysiloxane moieties is meant that x is an integer of at least 2. In certain embodiments of the first-fourth embodiments, the release treatment comprises polysiloxane moieties wherein x is an integer of at least 50. In certain embodiments of the first-fourth embodiments, the release treatment comprises polysiloxane moieties wherein x is an integer ranging from 2 to 400 (e.g., 2, 5, 10, 20, 30, 40, 50, 75, 100, 150, 200, 250, 300, 350, 400), including 2 to 350, 2 to 300, 2 to 250, 2 to 200, 2 to 150, 2 to 100, 2 to 75, 2 to 50, 5 to 350, 5 to 300, 5 to 250, 5 to 200, 5 to 150, 5 to 100, 5 to 75, 5 to 50, 10 to 350, 10 to 300, 10 to 250, 10 to 200, 10 to 150, 10 to 100, 10 to 75, 10 to 50, 50 to 400, 50 to 350, 50 to 300, 50 to 250, or 50 to 200. As those of skill in the art will appreciate, each Si in structure I is capable of forming four bonds in total and, thus, each intermediary Si (e.g., when x=4 this would be the 2^ndand 3^rdSi) is bonded to two hydrocarbyl groups and each terminal Si (e.g., when x=4 this would be the 1^stand 4^thSi) is bonded to two hydrocarbyl groups and one additional terminal group. Such polysiloxanes can be referred to as diorganopolysiloxanes. Notably, according to certain embodiments of the first-fourth embodiments, the two “organo” groups to which each intermediary Si is bonded need not be the same and each intermediary Si need not be bonded to the same two organo groups or the same combination of two organo groups. In certain embodiments of the first-fourth embodiments, the hydrocarbyl groups to which each intermediary Si is bonded comprise a methyl group; such a polysiloxane can be referred to as polydimethylsiloxane. Other exemplary polysiloxanes for use in effecting a release property to the lower surface of the inner liner during tire molding include, but are not limited to, dialkylpolysiloxanes such as diethylpolysiloxane, methylisopropyipolysiloxane, and methyldodecylpolysiloxane; diaryipolysiloxanes such as diphenylpolysiloxane; alkylphenyipolysiloxanes such as methylphenyipolysiloxane, dimethylsiloxane-methylphenylsiloxane copolymers, and dimethylsiloxane-diphenylsiloxane copolymers; alkylaralkylpolysiloxanes such as methyl(phenylethyl)polysiloxane and methyl(phenylpropyl)polysiloxane; and 3,3,3-trifluoropropylmethylpolysiloxane; in certain embodiments of the first-fourth embodiments, the release treatment comprises one or more of the foregoing polysiloxanes. The two organo groups on the intermediary Si and on the terminal Si of the polysiloxane may be independently selected from linear or branched alkyl having C1-C8, optionally substituted with at least one halogen (e.g., fluorine), and cycloalkyl having C3-C8. In certain embodiments of the first-fourth embodiments, each terminal Si of the polysiloxane chain is endblocked by a hydroxyl group, a hydrocarbyl group or an alkoxy group.

In certain embodiments of the methods of the first and third embodiments, the cured inner liner that has its lower surface treated with the rubber-containing liquid has not had its lower surface pre-treated with a release treatment comprising polysiloxane-moieties. In other words, in such embodiments of the first and third embodiments, the lower surface of the cured inner liner is essentially free of polysiloxane moieties. Similarly, in certain embodiments of the second and fourth embodiments, the cured inner liner with a lower surface which is essentially free of polysiloxane moieties. By essentially free of polysiloxane moieties is meant that the lower surface comprises less than 1% by weight, less than 0.5% by weight, less than 0.1% by weight, or even 0% by weight polysiloxane moieties. In certain embodiments of the first and third embodiments, the cured inner liner comprising rubber, a majority of which comprises butyl rubber (optionally halogenated) has a lower surface that is essentially free of polysiloxane moieties. Similarly, in certain embodiments of the second and fourth embodiments, the lower surface of the cured inner liner upon which includes (comprises) the rubber-containing film is essentially free of polysiloxane moieties. As discussed in more detail below, when the lower surface of the cured inner liner is essentially free of polysiloxane moieties, treatment with the rubber-containing liquid and drying of that rubber-containing liquid produces a rubber-containing film with adhesive properties. In other words, in such embodiments, the rubber-containing film (after drying or evaporation of solvent or solvents) is tacky or sticky. As referred to herein, the rubber-containing film is considered to be an adhesive film when it is capable of bonding to another surface (e.g., a foam noise barrier); as should be clear from the above description the capability of bonding to another surface is determined after drying or evaporation of solvent or solvents. Accordingly, in certain embodiments of the first-fourth embodiments, the rubber-containing film upon the lower surface of the inner liner comprises an adhesive film. In certain embodiments of the first-fourth embodiments, the adhesive film is sufficiently adhesive to allow adhesion of a polyurethane foam noise barrier with sufficient strength to exceed the tear strength of the polyurethane foam noise barrier; in certain such embodiments, the adhesive strength of the adhesive film is greater than 1.5 pounds per lineal inch of foam, and in other embodiments greater than 2 pounds per lineal inch of foam. Generally, when the adhesive film is sufficiently adhesive to allow adhesion of a polyurethane foam noise barrier with sufficient strength to exceed the tear strength of a polyurethane foam noise barrier, force applied in an attempt to remove the foam noise barrier from the lower surface of the inner liner will cause the foam to tear before causing the foam to separate from the lower surface of the inner liner at the adhesive film interface.

According to the first-fourth embodiments, the cured inner liner having a rubber-containing film upon its lower surface (as well as the cured inner liner which is treated with the rubber-containing liquid) comprises rubber, a majority by weight of which butyl rubber which is optionally halogenated. (Unless indicated to the contrary, the following discussion concerning rubber(s), filler(s) and other ingredients of the cured inner liner applies equally to the cured inner liner having a rubber-containing film upon its lower surface and to the cured inner liner which is treated with the rubber-containing liquid.) Moreover, the following discussion should also be understood as applying to the composition of the cured inner liner but not the rubber-containing film that is produced therein (as composition of the rubber-containing film is discussed in detail in a separate section). In other words, the cured inner liner comprises rubber, and a majority by weight of the rubber of such inner liner comprises one or more butyl rubbers and each of those butyl rubbers is optionally halogenated. (As discussed below, in certain embodiments of the first-fourth embodiments, the cured inner liner further comprises one or more fillers and optionally one or more curatives mixed with the butyl rubber(s).) Butyl rubber is a copolymer of isobutylene and a small amount of a diene-based monomer, typically isoprene or para-methylstyrene. The polymer chains of butyl rubber therefore typically have a highly saturated backbone. Butyl rubber typically contains more than about 90% isobutylene and less than about 10% diene-based monomer (e.g., isoprene or para-methylstyrene) by weight in the copolymer, including about 90-99.5% isobutylene and about 10 to about 0.5% diene-based monomer, about 95-99.5% isobutylene and about 5-0.5% diene-based monomer, about 96-99% isobutylene and about 4-1% diene-based monomer, about 97-98.5% isobutylene and about 1.5-3% diene-based monomer, and including about 98% isobutylene and about 2% diene-based monomer by weight in the copolymer. Typically, the diene-based mer (e.g., isoprenyl or para-methylstyrenyl) units are distributed randomly in the polymer chains of butyl rubber. Non-limiting examples of suitable polymers for use as the at least one butyl rubber or a halogenated butyl rubber of the cured inner liner according to certain embodiments of the first-fourth embodiments disclosed herein include, but are not limited to, butyl rubber, chlorobutyl rubber, bromobutyl rubber, fluorobutyl rubber, iodobutyl rubber, copolymers thereof, and combinations thereof. In certain embodiments of the first-fourth embodiments, the cured inner liner comprises bromobutyl rubber. In certain embodiments of the first-fourth embodiments, the only rubber present in the cured inner liner (excepting the rubber-containing film) is bromobutyl rubber (i.e., of 100 parts or 100 phr of rubber present in the cured inner liner all 100 parts or 100 phr is bromobutyl rubber).

In certain embodiments of the first-fourth embodiments disclosed herein, the cured inner liner comprises other ingredients in addition to the optionally halogenated butyl rubber(s). These other ingredients of the cured inner liner may vary but will generally include one or more fillers (e.g., carbon black, clay or silica) and a cure package (e.g., a vulcanizing agent such as sulfur and one or more vulcanization accelerators). In certain embodiments of the first-fourth embodiments disclosed herein, the cured inner liner comprises one or more butyl rubbers (optionally halogenated) and 10-100 phr (including 20-80 phr, 30-70 phr, 15 phr, 20 phr, 30 phr, 40 phr, 50 phr, 60 phr, 70 phr, 80 phr, 90 phr, etc.) of one or more of the foregoing fillers. In certain embodiments of the first-fourth embodiments, the rubber of the cured inner liner comprises at least 60% by weight (e.g., 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100% by weight) of at least one of: a butyl rubber or halogenated butyl rubber (or a combination thereof, as discussed above). In certain embodiments of the first-fourth embodiments, the rubber of the cured inner liner comprises at least one of the following rubbers in addition to the butyl or halogenated butyl rubber(s): natural rubber, polyisoprene, styrene-butadiene rubber, isoprene rubber, polybutadiene rubber (preferably at least 90% cis bond content, even more preferably at least 95% cis bond content), nitrile rubber (acrylonitrile-butadiene copolymers), or hydrogenated nitrile rubber.

The thickness of the cured inner liner utilized in or included within the first-fourth embodiments may vary. In certain embodiments of the first-fourth embodiments, the cured inner liner has a thickness of 0.5-2 mm. Since the thickness of the rubber-containing film is relatively small in comparison (as discussed further below), a thickness of 0.5-2 mm (to one or two significant digits) can be understood as applying to both the cured inner liner without the rubber-containing film as well as the cured inner liner with rubber-containing film upon its lower surface.

Rubber-Containing Liquid

As discussed above, according to the methods of the first and third embodiments disclosed herein, the lower surface of the cured inner liner is treated with a rubber-containing liquid. The rubber-containing liquid comprises at least one conjugated diene monomer-containing rubber, polyurethane and at least one solvent. By liquid is meant that the composition is pourable or at least flowable at room temperature (i.e., 23° C.). According to the first and third embodiments, the viscosity of the rubber-containing liquid may vary. In certain embodiments of the first and third embodiments, the rubber-containing liquid has a viscosity at room temperature of no more than 3000 centipoise, about 3000 to about 10 centipoise (e.g., 3000, 2500, 2000, 1500, 1000, 900, 800, 700, 600, 500, 400, 300, 200, 100, 50, 10 centipoise), 3000-10 centipoise, about 1500 to about 10 centipoise, 1500-10 centipoise, about 1000 to about 10 centipoise, 1000-10 centipoise, about 1000 to about 50 centipoise, or 1000-50 centipoise. The viscosities referred to herein can be determined using a Brookfield model RVF viscometer with a #3 spindle at 10 rpm for higher viscosities (greater than 1000) and a #2 spindle at 20 rpm for lower viscosities (1000 and less).

In certain embodiments of the first and third embodiments, the rubber-containing liquid comprises about 5 to about 40% (e.g., 5%, 8%, 10%, 15%, 18%, 20%, 25%, 30%, 35%, 40%) by weight of the at least one conjugated diene-monomer containing rubber. In certain embodiments of the first and third embodiments, the rubber-containing liquid comprises about 5 to about 25%, 5 to 25%, about 8 to about 25%, 8 to 25%, about 5 to about 20%, 5 to 20%, about 8 to about 20%, about 10 to about 20%, or 10 to 20% by weight of the at least one conjugated diene-monomer containing rubber. In certain embodiments of the first and third embodiments, the rubber-containing liquid has a solids content (i.e., based upon the total amount of conjugated diene-monomer containing rubber, polyurethane, and any filler(s)) of about 5 to about 45% (e.g., 5%, 8%, 10%, 15%, 18%, 20%, 25%, 30%, 35%, 40%, 45%). In certain embodiments of the first and third embodiments, the rubber-containing liquid has a solids content of about 5 to about 35%, 5 to 35%, about 8 to about 35%, 8 to 35%, about 5 to about 30%, 5 to 30%, about 8 to about 30%, 8 to 30%, about 5 to about 25%, 5 to 25%, about 8 to about 25%, 8 to 25%, about 5 to about 20%, 5 to 20%, about 8 to about 20%, or 8 to 20% by weight.

Rubber

As discussed above according to the methods of the first and third embodiments, the rubber-containing liquid utilized to treat the lower surface of the cured inner liner comprises at least one conjugated diene monomer-containing rubber. By conjugated diene monomer-containing rubber is meant a rubber polymer comprising at least one type of conjugated diene monomer. (The term polymer as used herein includes both homopolymers comprised of one type of monomer as well as copolymers comprised of two or more types of monomers.) It should be understood that the rubber or rubbers contained within the rubber-containing liquid will be the same rubber or rubbers contained within the rubber-containing film that is produced upon the lower surface of the inner liner. Similarly, as also discussed above the rubber-containing film of the second and fourth embodiments comprises at least one conjugated diene monomer-containing rubber. The rubber-containing liquid and/or rubber-containing film may comprise one or more than one conjugated diene monomer-containing rubber. While the concentration of conjugated diene monomer-containing rubber(s) within the rubber-containing liquid may vary (as discussed in more detail infra), the total amount of all conjugated diene monomer-containing rubber(s) should be understood as 100 parts or 100 phr so that the relative amount of other ingredients (i.e., polyurethane, solvent and optional ingredients such as filler(s) and isocyanate scavenger(s)) is provided in units of phr (i.e., parts per 100 parts rubber).

As those of skill in the art understand, a conjugated diene is a compound that has two double carbon-carbon bonds (i.e., two —C═C— bonds) that are separated by a single bond (i.e., —C—C—); thus, a conjugated diene will contain at least one —C═C—C═C— moiety. The particular structure of the conjugated diene monomer contained within the at least one conjugated diene monomer-containing rubber of the rubber-containing liquid and/or rubber-containing film of the first-fourth embodiments disclosed herein can vary. According to the first-fourth embodiments, one or more than one type of conjugated diene monomer can be utilized. By referring herein to one or more than one type of conjugated diene monomer is meant that the conjugated diene monomers may comprise all one formula or a mixture of formulas. As a non-limiting example, two types of conjugated diene monomers could encompass a combination of 1,3-butadiene and isoprene. In certain embodiments of the first-fourth embodiments disclosed herein, the conjugated diene monomer comprises at least one of 1,3-butadiene; isoprene; 1-3-pentadiene; 2,3-dimethyl-1,3-butadiene; 2-ethyl-1,3-butadiene; 2-methyl-1,3-pentadiene; 3-methyl-1,3-pentadiene; 4-methyl-1,3-pentadiene; 2,4-hexadiene; 1,3-hexadiene; 1,3-cyclopentadiene; 1,3-cyclohexadiene; 1,3-cycloheptadiene; or 1,3-cyclooctadiene. In certain embodiments of the first-fourth embodiments, the conjugated diene monomer comprises 1,3-butadiene. In certain embodiments of the first-fourth embodiments disclosed herein, the at least one conjugated diene monomer-containing rubber further comprises at least one type of vinyl aromatic monomer, i.e., in addition to the conjugated diene monomer. In certain embodiments of the first-fourth embodiments disclosed herein, the at least one type of vinyl aromatic monomer of the polymer chain comprises at least one of styrene, alpha-methyl styrene, p-methylstyrene, o-methylstyrene, p-butylstyrene, vinylnaphthalene, p-tertbutylstyrene, 4-vinylbiphenyl, 4-vinylbenzocyclobutene, 2-vinylnaphthalene, 9-vinylanthracene, 4-vinylanisole, or vinyl catechol. In certain embodiments of the first-fourth embodiments disclosed herein, the at least one type vinyl aromatic monomer of the conjugated diene monomer-containing rubber comprises styrene.

In certain embodiments of the first-fourth embodiments, the at least one conjugated diene monomer-containing rubber of rubber-containing liquid and/or the rubber-containing film comprises at least one of the following: butyl rubber, halogenated butyl rubber, polybutadiene (preferably at least 90% cis bond content, even more preferably at least 95% cis bond content), polyisoprene, natural rubber, or chlorinated polyisoprene; in certain such embodiments, a majority by weight (e.g., at least 51%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99% or even 100%) of the rubber(s) of the rubber-containing liquid and/or rubber-containing film comprises one or more of the foregoing. As should be clear from the above discussion, butyl rubber is a copolymer of isobutylene and a small amount of a diene-based monomer, typically isoprene or para-methylstyrene, in relative amounts as discussed above. A butyl rubber comprising isobutylene and para-methylstyrene can also be described as polyisobutylene para-methylstyrene whereas a butyl rubber comprising isobutylene and isoprene can also be described as polyisobutylene or isobutylene isoprene rubber. In certain embodiments of the first-fourth embodiments, the at least one conjugated diene monomer-containing rubber comprises at least one butyl rubber selected from: polyisobutylene or polyisobutylene para-methylstyrene. In certain embodiments of the first-fourth embodiments, the at least one conjugated diene monomer-containing rubber comprises at least one halogenated butyl rubber selected from: chlorobutyl rubber, bromobutyl rubber, fluorobutyl rubber, or iodobutyl rubber. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is free of (i.e., contains 0 phr of) any rubbers other than conjugated diene-monomer containing rubber(s). (As discussed herein, the polyurethane of the rubber-containing liquid and rubber-containing film is not considered to be a rubber.) In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film comprises butyl rubber, halogenated butyl rubber, or a combination thereof; in certain such embodiments a majority by weight (e.g., at least 51%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99% or even 100%) of the rubber(s) of the rubber-containing liquid and/or rubber-containing film comprises one or more of the foregoing. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film comprises 100 parts (or 100 phr) of butyl rubber, halogenated butyl rubber, or a combination thereof. In such embodiments, one or more than one butyl rubber may be utilized, one or more than one halogenated butyl rubber may be utilized, one butyl rubber and more than one halogenated butyl rubber may be utilized, more than one butyl rubber and one halogenated butyl rubber may be utilized, or more than one butyl rubber and more than one halogenated butyl rubber may be utilized. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is essentially free of (i.e., contains less than 5 phr or 0 phr) of chloroprene rubber or polychloroprene. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is essentially free of (i.e., contains less than 5 phr or more preferably 0 phr) of any silicone-containing or silicone-based rubber. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is essentially free of (i.e., contains less than 5 phr or more preferably 0 phr) of any acrylic-containing or acrylic-based polymer. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is essentially free of (i.e., contains less than 5 phr or more preferably 0 phr) of styrene-butadiene rubber. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is essentially free of (i.e., contains less than 5 phr or more preferably 0 phr) of any isocyanate-containing or isocyanate-based polymer. In certain embodiments of the first-fourth embodiments, the rubber-containing liquid and/or rubber-containing film is essentially free of (i.e., contains less than 5 phr or more preferably 0 phr) of thermoplastic resin and thermoplastic polymer (e.g., polyamide resins or polymers, polyester resins or polymers, polynitrile resins or polymers, poly(meth)acrylate resins or polymers, polyvinyl resins or polymers, cellulose resins or polymers, fluorine resins or polymers, imide resins or polymers).

Polyurethane

As discussed above, according to the methods of the first and third embodiments, the rubber-containing liquid utilized to treat the lower surface of the cured inner liner comprises polyurethane. It should be understood that the polyurethane contained within the rubber-containing liquid will also be present within the rubber-containing film that is produced upon the lower surface of the inner liner (i.e., after drying of the rubber-containing liquid). Similarly, in addition to containing the at least one conjugated diene monomer-containing rubber, the rubber-containing film of the second and fourth embodiments will also comprise (include) polyurethane. The polyurethane component of the rubber-containing liquid used in the methods of the first and third embodiments may be added as a pre-reacted polyurethane solution or alternatively (and preferably) may be added to the at least one conjugated diene monomer-containing rubber and solvent as its constituent components. These constituent components of the polyurethane comprise at least one polyol component and at least one isocyanate component; optional additional components include one or more catalysts, one or more chain extenders, and one or more isocyanate scavengers.

The amount of polyurethane contained with the rubber-containing liquid that is used in the methods of the first and third embodiments may vary. Likewise, the amount of polyurethane that is present in the rubber-containing film upon the lower surface of the cured inner liner according to the first-fourth embodiments may also vary. As mentioned above, the amount of polyurethane in the rubber-containing liquid and in the rubber-containing film is discussed herein as parts per hundred rubber (phr), based upon 100 parts or phr of the at least one conjugated diene monomer-containing rubber. Since neither the rubber nor the polyurethane evaporate (unlike the solvent) the relative amount of polyurethane to rubber will remain generally constant when a given rubber-containing liquid dries to produce a rubber-containing film. The amounts of polyurethane discussed herein refer to either the amount of pre-reacted polyurethane added to form the rubber-containing liquid or to the total amount of polyurethane constituent components added to form the rubber-containing liquid. Furthermore, since polyurethanes are frequently identified according to their constituent components and the relative amounts thereof, the discussion herein as to the amounts of polyol, isocyanate, and other constituents of the polyurethane should be understood to apply equally to both a pre-reacted polyurethane that is added to the rubber-containing liquid as well as to embodiments where the individual components are added to the liquid.

According to the methods of the first and third embodiments, the amount and type of polyol component that is used in the rubber-containing liquid may vary. One or more than one polyol component may be utilized.

According to the methods of the first-fourth embodiments, the ratio of polyol component to isocyanate component in the polyurethane of the rubber-containing liquid and/or in the polyurethane of the rubber-containing film may vary. In certain embodiments of the first-fourth embodiments, the polyol component is present in an amount sufficient to provide an excess of hydroxyl groups to isocyanate groups. In certain embodiments of the first-fourth embodiments, this excess comprises a ratio of hydroxyl group to isocyanate groups of greater than 2:1, about 2:1 to about 3:1, or about 2.5:1. In other embodiments of the first-fourth embodiments, when a tri-functional isocyanate is used, the ratio should be higher, e.g., greater than 4:1, about 4:1 to about 5:1 or about 4.5:1. On a weight basis, about 5 to about 15 phr (e.g., 5, 10, 15, 5-15, 5-10, 7-10 phr) of isocyanate component are used with about 15 to about 30 phr (e.g., 15, 20, 25, 30, 15-30, 15-25 phr) polyol component.

In certain embodiments of the first and third embodiments, the polyurethane component of the rubber-containing liquid includes at least one chain extender. Various chain extenders may be utilized.

In certain embodiments of the first and third embodiments, the catalyst is present in an amount of 1 to 10 phr, 2 to 5 phr, or 3 to 4 phr.

In certain embodiments of the first and third embodiments, the polyurethane component of the rubber-containing liquid includes at least one isocyanate scavenger. An isocyanate scavenger functions to scavenge any residual isocyanate groups after the polyol and isocyanate components have reacted. Exemplary isocyanate scavengers for use in the rubber-containing liquid of the first and third embodiments include methanol, other primary alcohols, water, secondary amines, and combinations thereof. The amount of isocyanate scavenger used in the rubber-containing liquid of the first and third embodiments may vary.

Allowing Liquid to Dry

As discussed above, according to the methods of the first and third embodiments, after the lower surface of the cured inner liner is treated with the rubber-containing liquid, the liquid is allowed to dry upon the treated surface of the cured inner liner, thereby producing a rubber-containing film upon the dried, treated surface (i.e., upon the lower surface of the inner liner). According to the methods of the first and third embodiments, the drying of the rubber-containing liquid upon the lower surface of the cured inner liner may employ various drying methods. According to certain embodiments of the first and third embodiments, the drying comprises at least one of: allowing the solvent(s) of the rubber-containing liquid to evaporate at room temperature; allowing the solvent(s) of the rubber-containing liquid to evaporate at a temperature above room temperature; circulating air (or a semi-inert or inert gas such as nitrogen or argon) that is at least one of room temperature, heated, or dehydrated over the treated surface of the cured inner liner; or subjecting the treated surface of the cured inner liner to a reduced pressure atmosphere. Preferably, the drying lasts less than 60 seconds, even more preferably less than 30 seconds or less than 15 seconds before sufficient solvent is removed to produce the rubber-containing film.

Rubber-Containing Film

As discussed above, according to the methods of the first and third embodiments, a rubber-containing film is produced upon the lower surface of the cured inner liner, i.e., from drying of the rubber-containing liquid. The rubber and polyurethane components of the rubber-containing liquid, as well as any filler contained therein, will remain upon drying of the liquid or in other words will be present in the rubber-containing film. Accordingly, the above discussion of conjugated diene monomer-containing rubbers, polyurethane and filler (i.e., in the section entitled “Rubber-Containing Liquid”) should be understood to apply equally to the composition of the rubber-containing film as if fully set forth herein. As also discussed above, according first-fourth embodiments, the lower surface of the inner liner includes a rubber-containing film. The thickness of this rubber-containing film may vary. According to the fourth embodiment and certain embodiments of the first-third embodiments, the rubber-containing film has a thickness of about 0.1 to about 25 micrometers (e.g., 0.1 micrometer, 0.5 micrometers, 1 micrometer, 2 micrometers, 5 micrometers, 10 micrometers, 15 micrometers, 20 micrometers or 25 micrometers). In certain embodiments of the first-fourth embodiments, the rubber-containing film has a thickness of 0.1-15 micrometers, 0.5-15 micrometers, or 1-15 micrometers.

According to the first-fourth embodiments, the rubber-containing film is on the lower surface of the cured inner liner. According to certain embodiments of the first-fourth embodiments, the rubber-containing film that is upon the lower surface of the cured inner liner can be understood as a coating upon the lower surface of the cured inner liner. Without being bound by theory, it is believed that the rubber-containing film is physically absorbed onto the lower surface of the inner liner. In those embodiments of the first-fourth embodiments wherein the rubber-containing liquid and/or rubber-containing film comprise a cure package, the rubber-containing film may covalently bond to the rubber within the lower surface of the cured inner liner.

Adhesive Film

According to certain embodiments of the methods of the first and third embodiments, the rubber-containing film that is produced upon the lower surface of the inner liner comprises an adhesive film. Similarly, in certain embodiments of the second and fourth embodiments, the rubber-containing film upon the lower surface of the cured inner liner comprises an adhesive film. Such films can be described as adhesive, rubber-containing films or rubber-containing adhesive films. In other words, such a rubber-containing film has adhesive properties and is tacky (after drying or evaporation of solvent or solvents) at room temperature. As referred to herein, the rubber-containing film is considered to be an adhesive film when it is capable of bonding to another surface (e.g., a foam noise barrier) at room temperature; as should be clear from the above description the capability of bonding to another surface is determined after drying or evaporation of solvent or solvents. Generally, according to the methods of the first and third embodiments, an adhesive, rubber-containing film can be produced upon the lower surface of the inner liner from the rubber-containing liquid when the lower surface of the inner liner that is treated with the rubber-containing liquid has not been pre-treated with a polysiloxane-containing release treatment. Thus, in certain such embodiments, the lower surface of the inner liner that is treated with the rubber-containing liquid is essentially free of polysiloxane moieties, as discussed above, resulting in an adhesive, rubber-containing film when the solvent of the rubber-containing liquid dries or evaporates. In certain embodiments of the second and fourth embodiments wherein the rubber-containing film upon the lower surface of the inner liner comprises an adhesive film, the lower surface of the inner liner (i.e., the rubber layer underlying the rubber-containing film) is essentially free of polysiloxane moieties, as discussed above. In those embodiments of the first-fourth embodiments wherein the rubber-containing film comprises an adhesive film and at least one component radially inward of the cured inner liner is adhered to the rubber-containing film it is preferable to position the at least one component upon the adhesive rubber-containing film before the solvent(s) have completely evaporated or been otherwise removed from the liquid.

Adhesion Film

Treating the Lower Surface

As discussed above, according to the methods of the first and third embodiments disclosed herein, the lower surface of the cured inner liner is treated with the rubber-containing liquid.

In other embodiments of the third and fourth embodiments disclosed herein, the at least one component radially inward of the inner liner does not directly contact the film-containing lower surface of the cured inner liner. In other words, a separate adhesive or other material is located between the at least one component and the rubber-containing film upon the lower surface of the cured inner liner. Generally, the at least one component may not directly contact the film-containing lower surface of the cured inner liner when the film (i.e., the rubber-containing film) comprises a non-adhesive film (e.g., an adhesion film).

In certain embodiments of the third and fourth embodiments, the at least one component comprises a noise barrier; in certain such embodiments, the noise barrier comprises a foam noise barrier. The noise barrier or foam noise barrier (when present) may be made from various materials. Generally, a light-weight and low-density flexible material such as foamed rubber, foamed synthetic resin, or cellular plastic will be utilized for a foam noise barrier. According to the third and fourth embodiments, the foam noise barrier (when present) may comprise a foamed material (or spongy materials) that is either an open-cell type or a closed-cell type, although open-cell types are preferred. As non-limiting examples, the material of the foam noise barrier (when present) may comprise a synthetic resin foam such as ether based polyurethane foam, ester based polyurethane foam, polyethylene foam and the like; rubber foam such as chloroprene rubber foam, ethylene-propylene rubber foam, nitrile rubber foam, silicone rubber foam, or a combination thereof. In certain embodiments of the third and fourth embodiments, the foam noise barrier (when present) comprises polyethylene foam, polyurethane foam, or a combination thereof. When a separate adhesive is used to adhere the noise barrier (or foam noise barrier), that adhesive may be applied to the noise barrier (or foam noise barrier), to the radially inner surface of the tire (i.e., the rubber-containing film upon the lower surface of the inner liner) to which the foam barrier (or foam noise barrier) will be adhered, or to both.

In certain embodiments of the third and fourth embodiments, the at least one component radially inner of the inner liner comprises a sealant layer, preferably without any adhesive layer between the sealant layer and the lower surface of the inner liner (i.e., the sealant layer directly contacts the rubber-film containing lower surface of the inner liner). In certain embodiments of the third and fourth embodiments, the sealant is applied to the tire inner liner and functions to seal a puncture (e.g., from a nail) and prevent air from leaking from the tire (or at least slow the air leakage) after the puncture.

In certain embodiments of the third and fourth embodiments, the at least one component radially inner of the inner liner comprises an air barrier layer, preferably without any adhesive layer between the air barrier layer and the lower surface of the inner liner (i.e., the air barrier directly contacts the lower surface of the inner liner). In certain embodiments, the air barrier layer is applied as a spray-on material and functions to enhance the air impermeability of the inner liner, thereby better retaining air within a pneumatic tire.

In certain embodiments of the third and fourth embodiments, the at least one component radially inner of the inner liner comprises a run-flat insert. In certain such embodiments, the run-flat insert comprises a self-supporting run-flat insert such as may be used in the sidewall of a tire to produce a run-flat tire or self-supporting run-flat tire. A run-flat insert that is used in the sidewall of a tire may be positioned either axially inward or axially outward of the body ply. In certain embodiments of the third and fourth embodiments, the run-flat insert will comprise the radially innermost (or axially innermost) component in the sidewall portion of the tire; in certain such embodiments, the inner liner will comprise the radially innermost component in the remaining portion of the tire.

In certain embodiments of the third and fourth embodiments, the at least one component radially inner of the inner liner comprises an electronic communication module. In certain embodiments of the third and fourth embodiments, the electronic communication module comprises a radio device; in certain such embodiments, at least a portion of the outer surface of the radio device is surrounded by a rubber coating. As used herein, the term radio device should be understood to include any suitable radio device known in the art capable of storing information (i.e., data), communicating information, or both storing and communicating information with another device. In certain embodiments of the third and fourth embodiments, the radio device disclosed herein is capable of conveying information. The conveying of information by the radio device comprises the receipt of a radio signal combined with transponding (by reflecting) a portion of the received radio signal back to a reader with a signal modulated by varying the radio device's antenna impedance. Generally, such a radio device which conveys information by transponding in response to being activated by energy (e.g., electromagnetic waves) sent by an external, remote transponder (e.g., an interrogator-type or reader-type of transponder) is considered a passive device. In certain embodiments, the radio device disclosed herein is capable of actively transmitting information; such a radio device is an active device because it can actively transmit information. Certain such active devices transmit without the need for any activation by an external, remote transponder (e.g., at periodic intervals) and other such active devices actively transmit information in response to an appropriate activation received from an external, remote transponder. In certain embodiments of the third and fourth embodiments disclosed herein, the radio device conveys or transmits information via electromagnetic radio waves having a frequency in the range that is allowable according to local regulations. For example, in the United States, this frequency generally ranges from about 900 MHz to about 930 MHz (including 900 MHz to 930 MHz) (the current approved range being 902-928 MHz at a power level not to exceed 36 dbm) and in portions of Europe and Asia may be at a somewhat lower frequency of about 860 MHz (including 860 Mz) (the current approved range in portions of Europe is 865.6-867.6 MHz at a power level not to exceed 33 dBm). Generally, the radio devices discussed herein will be designed to convey or transmit information at a frequency ranging from about 860 MHz to about 960 MHz (including 860 MHz to 960 MHz). However, in certain embodiments of the third and fourth embodiments disclosed herein, the radio devices discussed herein may be designed to convey or transmit information at another frequency range. Examples of suitable radio devices for use with the electronic communication modules disclosed herein include transponders (e.g., devices that both receive information and transpond at least a portion of it), transmitters, receivers, and reflectors. Generally, the radio device is configured to convey or transmit information to/from an external, remote communication device, which itself may be a transponder, transmitter, receiver, or reflector depending on the functionality of the radio device of the electronic communication module of the third and fourth embodiments that it is communicating with (e.g., if the remote communication device is a transmitter, the electronic communication module's radio device is a transponder, receiver, or reflector capable of interacting with the electromagnetic waves sent from the transmitter). As used herein, the term “radio device” is inclusive of any and all of the components necessary to operate as a transponder, transmitter, receiver, or reflector, e.g., a circuit board, memory, antenna, etc.

In certain embodiments of the first-fourth embodiments, the rubber-containing film which is created or present upon the treated lower surface of the cured inner liner results in the ability to adhere at least one component (e.g., a foam noise barrier) to the inner liner.

The foregoing peel strength numbers and ranges refer to measurements made at 23° C. The peel strength measurements can be made according to ASTM Procedure D903 and/or according to ASTM Procedure D1876 and utilizing a sample (e.g., from a tire or a partially assembled tire) containing an inner liner, a rubber-containing film, and a component such as a noise barrier adhered to the inner liner via the rubber-containing film. In certain embodiments, the foregoing peel strength numbers and ranges refer to measurements made using pressure sensitive adhesive or pressure sensitive tape to adhere the component to the inner liner via the rubber-containing film. In certain embodiments, the foregoing peel strength numbers and ranges refer to measurements made upon an inner liner which has a lower surface comprising a release treatment comprising polysiloxane moieties. In certain embodiments, the foregoing peel strength numbers and ranges refer to measurements made upon an inner liner which has a lower surface essentially free of polysiloxane moeities.

When measuring peel strength, the measurement may be made upon a sample cut from an assembled component/adhesive/rubber-containing film/inner liner combination or may be prepared especially for testing (using the same ingredients for the inner liner, adhesive and rubber-containing film. When a sample is prepared especially for testing, the sample is preferably prepared adhering the component to the inner liner via the rubber-containing film. Alternatively, a sample may be prepared for testing using the same ingredients for the inner liner, adhesive and rubber-containing film but substituting a butyl rubber sheet for the component; using the foregoing type of sample may be especially useful when the product in question is manufactured or sold in a state that does not (yet) include an adhered component such as a foam noise barrier. The foregoing peel strength numbers and ranges are intended to refer to average numbers that can be obtained by averaging the result of three or four duplicate tests. When peel strength data is obtained in a form which separates measurements for peaks and valleys, the foregoing peel strength numbers and ranges refer to an average of the average peak and average valley measurement. In certain embodiments of the first-fourth embodiments, at least one of the average peak and average valley measurement falls within one of the foregoing ranges; in certain such embodiments, both the average peak and the average valley measurements fall within one of the foregoing ranges.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims are generally intended as “open” terms. For example, the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to.” It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

All references, including but not limited to patents, patent applications, and non-patent literature are hereby incorporated by reference herein in their entirety.

While various aspects and embodiments of the compositions and methods have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the claims.
