The present invention relates to a vehicle interior component with an improved polymer composition.
It is known to produce aliphatic polyketone material prepared by polymerizing ethylene, propylene and carbon monoxide and with a regular linear structure; the material is characterized by simple synthetic raw materials and the capacity of consuming carbon monoxide (e.g. and thus considered as an environment-friendly material). The polyketone product has better dimensional stability. The polyketone has fluidity adjustable in a large range, and good impact performance and wear resistance. The polyketone material can be used as an injection molded piece for automotive interiors as a substitution of some nylon materials. In order to use a polyketone material as a load-bearing automotive interior injection molded piece, a reinforcing material is required as a filler and for reinforcement (e.g. fibers such as glass fibers, carbon fibers and the like are generally used). A relatively large crystallinity and relatively fast crystallization rate of the polyketone material may improve the mechanical properties and shorten the processing period of the material but may cause the surface to form/solidify more quickly; and consequently reinforcing materials such as glass fibers are more likely to be visible at the surface layer (e.g. visible fiber emergence, which adversely affects the appearance of the injection molded piece and that may require treatment of the surface such as by painting, spraying, etc.).
It would be advantageous to provide an improved vehicle interior component with an improved polymer composite to present suitable mechanical properties and an acceptable effect/visual appearance at the surface without requiring treatment which may be achieved by desired/qualified values of crystallinity and crystallization rate (defined as reciprocal of half crystallization time) of the polymer composition correlated to the acceptable effect/appearance.

The component may provide crystallinity in a range of between about 17 to 26 percent. The component may provide half-time of crystallization of between about 42 and 51 seconds. The effect on the surface may be provided by crystallinity and a crystallization rate of the composition; the effect may comprise a substantially consistent visual effect at the surface. The crystallization rate may be characterized by the reciprocal half-time of crystallization for formation of the composition.

According to an exemplary embodiment, the method of preparing/producing the component from the polymer material may comprise the combination of the compatible resin, the copolymer resin and the compatibilizer added in a modification process for the polyketone; crystallization of the polyketone in the modification process is disturbed; the crystallinity of the polyketone is reduced, the crystallization rate is slowed; the reinforcing material is sufficiently infiltrated in the cooling process of the mold; the reinforcing material emergence is reduced at the surface of an injection molded part/component to improve the visual appearance of the injection molded piece/part made of the reinforced polyketone composite material/particles. According to an exemplary embodiment, the method may be used to prepare injection molded pieces/parts to satisfy stringent appearance requirements (e.g. including by effectively preventing/reducing the reinforcing material emergence on the surface of the component).
According to an exemplary embodiment as indicated in TABLE 2, operating conditions to produce a component using the formulation and method comprise mold temperature for the injection mold/tool surfaces (e.g. preferred range 110-140 degrees Centigrade (deg C.) and optimal range 125-135 deg C.); mold temperature in injection molding is observed as a factor to control the surface quality of the molded parts. See
As indicated schematically, selection and control of operating conditions for the injection molding operation may facilitate performance improvement; test and comparative examples (under the operating conditions of time, temperature, etc.) were completed to determine suitable performance/ranges for the formulation of the polymer composition to produce components.
According to an exemplary embodiment it was intended to provide an improved polymer composite (for formation/production of an improved vehicle interior component) in a formulation to present suitable mechanical properties and an acceptable effect/visual appearance at the surface without requiring treatment which may be achieved by a range of desired/qualified values of crystallinity and crystallization rate (characterized by the reciprocal half-time of crystallization) of the polymer composition correlated to the acceptable effect/visual appearance.
As indicated according to an exemplary embodiment in TABLE 3A, Examples 1-4 were considered to represent a composition (e.g. compositional range of polyketone resin, compatible resin, copolymer, compatibilizer, reinforcing material/glass fiber with other constituents) to producing a crystallinity and crystallization rate believed to provide a suitable visual appearance (e.g. acceptable and preferred). See
As indicated in TABLE 3A according to an exemplary embodiment, application of the method and composition for Example 1 through 4 resulted in production of example components determined to provide an acceptable visual appearance. See for example
In the example, the mass of copolymer is reduced and the mass of compatibilizer is increased; crystallinity, crystallization rate and half-time of crystallization are suitable to provide acceptable visual appearance (as intended).
In the example, the total mass of copolymer and compatibilizer is reduced; crystallinity, crystallization rate and half-time of crystallization are suitable to provide acceptable visual appearance (e.g. within qualified/critical value).
In the example, with added compatible resin and copolymer and compatibilizer, the total mass of compatible resin and copolymer is largest; crystallinity is reduced, crystallization rate is reduced and half-time of crystallization is increased to provide acceptable visual appearance (e.g. not optimum but within qualified/critical value).
In the example, the mass of compatible resin is reduced; crystallinity, crystallization rate and half-time of crystallization are suitable/improved to provide acceptable/improved visual appearance (e.g. within qualified/critical value).
As indicated according to an exemplary embodiment in TABLE 3B, the Comparable Examples 1-4 were considered to represent a composition (e.g. compositional range of polyketone resin, compatible resin, polyamide, copolymer, compatibilizer, reinforcing material/glass fiber with other constituents) to producing a crystallinity, crystallization rate and half-time of crystallization believed to provide a varying visual appearance (not preferred and acceptable). See
As indicated in TABLE 3B according to an exemplary embodiment, application of the method and composition for Comparable Examples 1 through 4 resulted in production of example components determined to provide a not-preferred visual appearance. See for example
In the example, a conventional formulation is used that does not comprise compatible resin, copolymer, polyamide (PA6) or compatibilizer; crystallinity is beyond an accepted/qualified range (e.g. due to high crystallinity of polyketone resin constituent); example indicates to reduce crystallinity by reducing the mass of polyketone resin by adding compatible resin and copolymer to provide an acceptable rather than not-preferred visual appearance.
In the example, replacement of copolymer with polyamide (PA6) as a potential cost-saving measure; crystallinity, crystallization rate and half-time of crystallization are non-ideal to provide intended/acceptable visual appearance.
In the example, replacement of compatible resin with polyamide (PA6); crystallinity, crystallization rate and half-time of crystallization are non-ideal to provide intended/acceptable visual appearance.
In the example, without added polyamide (PA6) and with removal of compatibilizer; crystallinity is acceptable but the generation of microcrystal structures of the polyketone resin is reduced and the crystallization is beyond acceptable/qualified range to provide acceptable visual appearance; example indicates that compatibilizer provides a beneficial effect (e.g. may be necessary for formulation).
As indicated in TABLES 3A and 3B, it appears that both crystallinity (within qualified scope) and crystallinity rate (characterized by the reciprocal half-time of crystallization) (within qualified scope) will correlate to an intended/desired visible appearance. Crystallinity rate (e.g. outside of the qualified range/scope of half-time of crystallization of 42-51 seconds) will produce a component that if too low will present a visual appearance not-preferred and that if too high will provide unsuitable mechanical properties (such as inadequate tensile strength and bending modulus). Crystallinity (e.g. outside of the qualified scope of 17-26 percent) will produce a component that if too high will present a visual appearance not preferred and that if too low will provide unsuitable mechanical properties (such as inadequate tensile strength and bending modulus).
According to an exemplary embodiment, the attributes of the formulation of the polymer composition for the component are intended to produce an acceptable appearance and suitable mechanical performance/properties; the reinforcing material or antioxidant or light stabilizer or lubricant or toner provided an auxiliary role; for example, the light stabilizer functions as anti-ultraviolet and anti-photo-aging protection. To reduce the crystallization rate and increase the half-time of crystallization may reduce glass fiber exposure through the component and the not-preferred effect shown schematically in
According to an exemplary embodiment, a component for a vehicle interior configured to provide a surface and formed from a polymer composition may be provided. The composition may comprise (by mass fraction in percent by weight) polyketone resin in a range of less than about 40 weight percent, compatible resin; copolymer; compatibilizer; reinforcing material. An improved polymer composite (for formation/production of an improved vehicle interior component) may be provided in a formulation to present suitable mechanical properties and an acceptable effect/visual appearance at the surface (without requiring treatment) achieved by a range of desired/qualified values of crystallinity and crystallization rate (characterized by the reciprocal half-time of crystallization) of the polymer composition correlated to the acceptable effect/visual appearance. The composition may be formed to provide a crystallinity above about 15 percent; the composition may be formed to provide a half-time of crystallization above about 42 seconds; an intended/desired effect on the surface may be provided by the composition as a result of the crystallinity (in a range of between about 15 and 26 percent) and the half-time of crystallization in a range of between about 42 and 51 seconds). A method of forming the component is also disclosed.
As indicated according to an exemplary embodiment in TABLES 3A-3B and 4, the Examples 1 to 8 were considered to represent a composition (e.g. compositional range of polyketone resin, compatible resin, polyamide, copolymer, compatibilizer, reinforcing material/glass fiber with other constituents) to producing a crystallinity, crystallization rate and half-time of crystallization believed to provide a varying visual appearance (acceptable and preferred and not preferred); crystallinity for the compositions of each of Examples 1 to 8 is shown in a graph provided as
According to an exemplary embodiment, a component may be produced from a polymer composition comprising a range of constituents intended to provide intended physical/performance characteristics including but not limited to an intended visual appearance/effect as indicated schematically in
According to an exemplary embodiment, an effect on the surface of the component is provided by the composition as a result of the crystallinity, the crystallization rate and the half-time of crystallization.

The effect may comprise a visual appearance. The visual appearance may comprise a substantially consistent surface effect. The effect may comprise a substantially consistent visual effect at the surface. The isothermal crystallization rate can be described by the half-time of the crystallization process, which is defined as the time consumed to reach half of the final crystallinity. Such time increases as the crystallization temperature increases, which is due to diffusion-controlled crystallization (e.g. measured under isothermal conditions at 185 degrees Centigrade). As indicated schematically according to an exemplary embodiment, a relatively large crystallinity and relatively fast crystallization rate of the polyketone material may improve the mechanical properties and shorten the processing period of the material and of the part/component derived from these materials but may cause the surface (of the parts) to form/solidify (e.g. fix, etc.) more quickly; and consequently reinforcing materials such as glass fibers are more likely to be visible at the surface layer (e.g. visible fiber emergence, which adversely affects the appearance of the injection molded piece and that may require treatment of the surface such as by painting, spraying, etc.).
