The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
Reference will now be made in detail to certain embodiments of the disclosed subject matter, examples of which are illustrated in part in the accompanying drawings. While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the exemplified subject matter is not intended to limit the claims to the disclosed subject matter.
Throughout this document, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range. The statement “about X to Y” has the same meaning as “about X to about Y,” unless indicated otherwise. Likewise, the statement “about X, Y, or about Z” has the same meaning as “about X, about Y, or about Z,” unless indicated otherwise.
In this document, the terms “a,” “an,” or “the” are used to include one or more than one unless the context clearly dictates otherwise. The term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. The statement “at least one of A and B” has the same meaning as “A, B, or A and B.” In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Any use of section headings is intended to aid reading of the document and is not to be interpreted as limiting; information that is relevant to a section heading may occur within or outside of that particular section.
In the methods described herein, the acts can be carried out in any order without departing from the principles of the disclosure, except when a temporal or operational sequence is explicitly recited. Furthermore, specified acts can be carried out concurrently unless explicit claim language recites that they be carried out separately. For example, a claimed act of doing X and a claimed act of doing Y can be conducted simultaneously within a single operation, and the resulting process will fall within the literal scope of the claimed process.
The term “about” as used herein can allow for a degree of variability in a value or range, for example, within 10%, within 5%, or within 1% of a stated value or of a stated limit of a range, and includes the exact stated value or range.
The term “substantially” as used herein refers to a majority of, or mostly, as in at least about 50%, 60%, 70%, 80%, 900%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 99.99%, or at least about 99.999% or more, or 100%.
Various embodiments of the present disclosure relate to a coagulatable mixture that can be used to rapidly seal one or more punctures in a tire. The coagulatable mixture can be included in a tire in an uncoagulated state and then upon formation of a puncture at least a portion of the coagulatable mixture can rapidly gather at the puncture site, coagulate, and stop the flow of air exiting the tire. This can allow the user of the tire to continue to use the tire for a longer amount of time, which may be sufficient to allow the user to have the tire repaired or replaced.
In operation, tire punctures can happen in many different ways. For example, a car tire can be punctured by running over a nail or other debris on a road. A bicycle tire can be punctured by a sharp rock on a trail. An aircraft tire can be punctured by debris on a runway or tarmac. However the puncture or punctures are formed, the result can be for the air in the tire to rapidly exit the tire, resulting in a flat tire and potentially momentarily loss of control of the vehicle. The instantly described coagulatable mixture, however, is capable of rapidly sealing the puncture or punctures to substantially prevent or delay formation of a flat tire.
Various embodiments of the coagulatable mixture include a solvent component, an antifreeze component, a latex component, and a solid filler component. These components can exist as a mixture with no components isolated from each other. The mixture can be a homogenous or heterogeneous mixture. The coagulatable mixture can be evenly distributed about an interior of a tire, thus increasing the ability of the mixture to be rapidly deployed to the puncture site.
The solvent can be any solvent that is capable of accommodating the components of the mixture. The solvent should not be one that is capable of reacting with the material of the tire, rim, or any sensors disposed within the tire (e.g., an air pressure sensor). Examples of suitable solvents include aqueous or organic solvents. Examples of organic solvents include turpentine, xylene, and a mixture thereof. Examples of aqueous solvents include water, ammonia, or a mixture thereof. The solvent component can be in any weight percentage (wt %) of the coagulatable mixture. For example, the solvent component can be in a range of from about 20 wt % to about 80 wt % of the coagulatable mixture, about 40 wt % to about 60 wt %, less than, equal to, or greater than about 20 wt %, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, or about 80 wt % of the coagulatable mixture.
The antifreeze component can help to ensure that the coagulatable mixture will not freeze at certain temperatures at which the tires are used. For example, automobile tires may be used in northern climates during the winter where they may be exposed to temperatures that are capable of freezing the coagulatable mixture, absent the antifreeze component. Alternatively, if the coagulatable mixture is deployed in an aircraft tire, the aircraft may be at high altitudes for extended periods of time where the ambient temperature is capable of freezing the coagulatable mixture. If the mixture is frozen, it may not be able to flow to the puncture in the tire.
The antifreeze component can be chosen from any antifreeze component having a desired freezing point. For example, a freezing point of the antifreeze component can be in a range of from about −40° C. to about 5° C., about −30° C. to about 0° C., less than, equal to, or greater than about −40° C., −35, −30, −25, −20, −15, −10, −5, or about 0° C. Examples of suitable antifreeze components include methanol, glycerol, ethylene glycol, propylene glycol, propylene glycerol, or a mixture thereof. The antifreeze component can be in a range of from about 20 wt % to about 50 wt % of the coagulatable mixture, about 30 wt % to about 40 wt %, less than, equal to, or greater than about 20 wt %, 25, 30, 35, 40, 45, or about 50 wt % of the coagulatable mixture.
The latex component provides an adhesive function to the coagulatable mixture. Once a puncture is formed, the latex is able to adhere components of the mixture together and dry to form a coagulated mixture. The latex component can include a natural or synthetic rubber latex emulsion or dispersion. The latex component can further include an accelerator such as a vulcanizer, an antioxidant, an activator, a tackifier, a dithiocarbamate, a thiuram, a thiourea, a thiazol, zinc oxide, or a mixture thereof.
Examples of commercially available latex components that can be included in the coagulatable mixture can include HF-30, HX-80, HX-80LA, HX-200, HX-660, HX-874, or HX-807 all available from Holden's Latex Corp., New York, N.Y., USA. Specific selection of a latex can be driven by considerations such as the solids content of the latex component, the viscosity of latex component, whether the latex is vulcanized, or whether the latex is ammoniated. The latex component can be in a range of from about 10 wt % to about 80 wt % of the coagulatable mixture, about 20 wt % to about 40 wt %, less than, equal to, or greater than about 10 wt %, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, or about 80 wt % of the coagulatable mixture.
The solid filler component acts to create a physical barrier for air escaping a puncture in the tire. In various embodiments, the solid filler component includes a mixture of solid filler particulate material (e.g., a collection of particles) that are able to aggregate and be held in place when the latex component is dried. A largest dimension of the individual solid filler particles can independently be in a range of from about 0.10 mm to about 5 mm, about 0.25 mm to about 0.35 mm, less than, equal to, or greater than about 0.10 mm, 0.50, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or about 5 mm. Individual particles can have a precision shape (e.g., a platelet or sphere) or an irregular shape. The largest dimension can correspond to a length, diameter, width, or thickness of the individual particulate filler.
The individual particulate fillers can include many suitable materials. For example, the individual particles can include a natural material, a synthetic material, or a combination thereof. For example, individual particulate fillers can include natural rubber, synthetic rubber, poly-praraphenylene terephtalamide, Zea mays, mica, piperaceae, glitter, coffea, talc, or a mixture thereof. In embodiments where individual particulate fillers include natural or synthetic rubber, the rubber can be a recycled rubber. The solid filler component can be in a range of from about 20 wt % to about 80 wt % of the coagulatable mixture, about 40 wt % to about 60 wt %, less than, equal to, or greater than about 20 wt %, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, or about 80 wt % of the coagulatable mixture.
The coagulatable mixture can include any further components that may be necessary or desirable. For example, the coagulatable mixture can include a plurality of ceramic beads. If present, the ceramic beads can function to evenly distribute the coagulatable mixture about the interior of the tire. This can help to ensure that at least a majority of the solid filler component particles remain suspended in the mixture. For example, the ceramic beads can be of a sufficient mass that they can dislodge and move the coagulatable mixture to prevent the coagulatable mixture from agglomerating at a particular location. A largest dimension of the individual ceramic beads can independently be in a range of from about 0.10 mm to about 5 mm, about 0.25 mm to about 0.35 mm, less than, equal to, or greater than about 0.10 mm, 0.50, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, or about 5 mm. Individual ceramic beads can have a precision shape (e.g., a platelet or sphere) or an irregular shape. The largest dimension can correspond to a length, diameter, width, or thickness of the individual particulate filler. Although ceramic materials are described, any other solid particle that is capable of mixing the coagulatable mixture may be included. The ceramic beads can include a material chosen from an alpha-alumina, a fused aluminum oxide, a heat-treated aluminum oxide, a ceramic aluminum oxide, a sintered aluminum oxide, a silicon carbide, a titanium diboride, a boron carbide, a tungsten carbide, a titanium carbide, a diamond, a cubic boron nitride, a garnet, a fused alumina-zirconia, a sol-gel derived abrasive particle, a cerium oxide, a zirconium oxide, a titanium oxide, and combinations thereof.
The coagulatable mixture can be tuned to have many desirable properties. For example, the pH of the coagulatable mixture can have a neutral or only slightly acidic or basic value. For example, a pH of the coagulatable mixture can be in a range of from about 6 to about 8 or can be about 7. Controlling the pH of the coagulatable mixture can help to mitigate the risk that the coagulatable mixture will destroy or corrode the tire, or any component thereof such as a tire pressure sensor. The risk of corrosion can be further mitigated by not including certain corrosive components such as ammonium nitrate.
The coagulatable mixture can be made according to any suitable method. For example, each of the solvent component, the latex component, the antifreeze component, and the solid filler component, as well as any further optional components, can be mixed before being disposed in a tire. This in in direct contrast to other mixtures in which the components are not mixed before they are put in a tire.
In some embodiments, the components of the mixture can be mixed in a particular order. For example, the latex component can be added to the mixture after the solvent component, and the antifreeze component can be added after the latex component. Adding the components in this order may be advantages when the antifreeze component includes propylene glycerol, propylene glycol. This is because propylene glycerol will generate foam if it is mixed with or before water and latex.
The coagulatable mixture can be a component of a tire or tire assembly. For example,
As generally understood, a tire can refer to a ring-shaped component that surrounds rim 106 to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface traveled over. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively.
The materials of pneumatic tires can include synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. The can include a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Pneumatic tires are used on many types of vehicles, mentioned herein including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Pneumatic tires can also be used in various non-automotive applications, such as some casters, carts, lawnmowers, and wheelbarrows.
Rim 106 can include any suitable material. General considerations for rim 106 include the strength of the material and in some circumstances the weight of the material. Examples of suitable materials that the rim can include are a metal, a plastic, a composite, or a mixture thereof. Examples of suitable metals include chrome, aluminum, iron, mixtures thereof, or alloys thereof. Examples of suitable composites include a carbon fiber, graphite, graphene, or mixtures thereof. Rim 106 can include components such as air valve 110, which allow compressed air to be delivered to space 108. Rim 106 can further include a sensor that can transmit data relating the air pressure in space 108, the rotations per minute of tire 104, the balance of tire 104, or any other desired property.
As shown in
Coagulatable mixture 100 can be incorporated into tire 104 at the time the tire 104 is manufactured or after tire 104 is attached to rim 106. In embodiments in which coagulatable mixture 100 is added after tire 104 is attached to rim 106, coagulatable mixture 100 may be injected into space 108 via air valve 110. After coagulatable mixture 100 is disposed in space 108, tire 104 is rotated to evenly distribute coagulatable mixture 100 about the interior surface of tire 104, rim 106, or both. To ensure adequate dispersion, tire 104 can be rotated for any suitable amount of time. For example, tire can be rotated for about 0.5 minutes to about 240 minutes, about, 1 minute to about 20 minutes, less than, equal to, or greater than about 0.5 minutes, 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, 180, 185, 190, 200, 205, 210, 215, 220, 225, 230, 235, or about 240 minutes. Tire 104 can be rotated at about 2 to about 60 miles per hour (MPH) about 20 mph to about 40 mph, less than, equal to, or greater than about 2 mph, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, about 60 mph, or in excess of 20 mph. Following rotation, coagulatable mixture 100 is evenly distributed about tire 104. At least a portion of coagulatable mixture 100 is evenly distributed about the interior surface of tire 104 and rim 106, respectively as film 100B. Liquid portion 100A will be evenly distributed about the interior surface of tire 104 and rim 106 when tire 104 is rotated during use, when tire 104 is at rest liquid coagulatable mixture 100A may pool in one location, but will be redistributed when the tire is rotated again during use.
In operation, when a puncture is formed in tire 100, air begins to leave space 108 and flow to the exterior environment. As the air flows from space 108 the coagulatable mixture is brought with it. The solid filler component begins to catch and aggregate with each other at and about the puncture. At the same time the latex component begins to dry and act as an adhesive between the solid filler component and tire 104. Eventually enough solid filler component is aggregated and adhere about the puncture that air is no longer able to flow from space 108 to the exterior environment, thus preventing further leakage of air from tire 104.
Coagulatable mixture 100 is capable of sealing a puncture have a wide variety of major dimensions (e.g., a largest diameter, length, or width). For example, a major dimension of the puncture can be in a range of from about 0.5 mm to about 80 mm, about 2 mm to about 8 mm, less than, equal to, or greater than about 0.5 mm, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, or about 80 mm. The puncture is capable of being sealed very rapidly irrespective of the size of the puncture. For example, the puncture can be sealed in about 0.5 seconds to about 5 seconds, measured from the creation of the puncture, about 1 second to about 2 seconds, less than, equal to, or greater than about 0.5 seconds, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4, 4.25, 4.5, 4.75, or about 5 seconds.
Although only one puncture is described, it is within the scope of this disclosure for coagulatable mixture 100 to be capable of sealing any plural number of punctures in tire 104, whether formed simultaneously or not. The ability to rapidly seal one or more punctures of a wide variety of sizes can allow for tire 104 to be used for a great distance so that tire 104 can be brought to a repair shop for replacement or maintenance. For example, tire 104, after being sealed, can be used for about 2 miles to about 500 miles, about 50 miles to about 300 miles, less than, equal to, or greater than about 2 miles, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, or about 500 miles.
Coagulatable mixture 100 can be effective for a very large amount of time after being injected into space 108. For example, coagulatable mixture 100 may not need to be replaced for an amount of time ranging from about 2 months to about 36 months, about 3 months to about 12 months, less than, equal to, or greater than about 2 months, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20, 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, 25.5, 26, 26.5, 27, 27.5, 28, 28.5, 29, 29.5, 30, 30.5, 31, 31.5, 32, 32.5, 33, 33.5, 34, 34.5, 35, 35.5, or about 36 months.
