    摘要: The invention relates to preparation of silica-rich rubber compositions by a sequence of sequential mixing steps conducted in internal rubber mixer(s) with individual maximum temperature limitations. The mixing steps are comprised of at least two non-productive mixing steps followed by a productive mixing step. The non-productive mixing steps themselves are comprised of at least one preliminary non-productive mixing step followed by a final non-productive mixing step. Elastomer, silica and coupling agent are added in at least one of said preliminary non-productive mixing steps to the exclusion of said final non-productive mixing step and said productive mixing step. Sulfur and sulfur vulcanization accelerator(s) are added in said productive mixing step to the exclusion of said non-productive mixing steps. The preliminary non-productive mixing step(s) are individually conducted to a maximum mixing temperature in a range of from about 150° C. to about 180° followed by the final non-productive mixing step to a reduced maximum mixing temperature in a range of from about 90° C. to about 130° C. The maximum mixing temperature of said final non-productive mixing step is at least 20° C. lower than the maximum temperature for said preliminary non-productive mixing stage(s). The productive mixing step is conducted to a maximum temperature in a range of from about 90° C. to about 120° C. The rubber composition is removed from its respective internal rubber mixer and cooled to below 40° C. between said mixing steps. The invention is further intended to relate to a rubber composition prepared by such mixing process and to a tire having at least one component comprised of such rubber composition.

    摘要: A method of producing a tire including mixing in a non-productive phase at least one elastomer with a polyamide having a melting temperature of less than 180° C. The polyamide is allowed to heat to at least its melting temperature. During the productive phase, at least one curing agent is added to the elastomeric composition. The curing agent may be a sulfur containing curing agent and/or a non-sulfur containing curing agent. The elastomeric composition may optionally include a crystalline EPDM elastomer. The resulting compositions may then be formed into a tire component which may be built into a tire and cured.

    摘要: The invention relates to a tire having a rubber tread comprised of cap/base construction where the tread outer cap rubber layer contains the running surface of the tread and the tread base rubber layer underlies the tread cap layer wherein the base layer provides a transition zone between the tread cap layer and the remainder of the tire carcass and is not intended to be ground-contacting. For this invention, the tread base rubber layer is comprised of three distinct zones, namely a circumferential annular central rubber zone positioned between two lateral annular rubber zones. In one aspect, the rubber tread cap layer and zoned rubber tread base layer are co-extruded together to form an integral tread rubber composite.

    摘要: This invention relates to a tire having at least one rubber component which contains a cast, extruded, or calendered film of syndiotactic polybutadiene polymer. The syndiotactic polybutadiene polymer film is integral with the surface of the rubber component in a sense of being co-cured therewith. Such film may be added directly to the tire during the building process or involve a separate process of producing a tire component as a composite of the film and a rubber composition (rubber component) prior to the tire building stage. Such composite can be as is or partially pre-cured before being applied in the tire building process. The syndiotactic polybutadiene polymer film is provided to promote both stability and age durability for the tire component.
