    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.

    摘要翻译： 本发明涉及通过在具有单独的最大温度限制的内部橡胶混合器中进行的连续混合步骤的顺序来制备富含二氧化硅的橡胶组合物。 混合步骤包括至少两个非生产性混合步骤，随后是生产性混合步骤。 非生产性混合步骤本身包括至少一个初步非生产性混合步骤，随后是最终的非生产性混合步骤。 在至少一个所述初步非生产性混合步骤中加入弹性体，二氧化硅和偶联剂，排除所述最终非生产性混合步骤和所述生产混合步骤。 在所述生产性混合步骤中加入硫和硫硫化促进剂以排除所述非生产性混合步骤。 初步的非生产性混合步骤分别进行至约150℃至约180℃的最大混合温度，随后进行最终的非生产性混合步骤，使得最大混合温度在一定范围内降低 约90℃至约130℃。所述最终非生产性混合步骤的最大混合温度比所述初步非生产性混合阶段的最高温度低至少20℃。 生产混合步骤进行到约90℃至约120℃范围内的最高温度。将橡胶组合物从其相应的内部橡胶混合器中除去并在所述混合步骤之间冷却至低于40℃。 本发明进一步旨在涉及通过这种混合方法制备的橡胶组合物和具有至少一种由这种橡胶组合物组成的组分的轮胎。

    摘要： This invention relates to a pneumatic rubber tire having a rubber sidewall composition of a lug and groove configuration which is designed to be ground contacting. Such sidewall configuration is of a rubber composition comprised of a blend of natural rubber and cis 1,4-polybutadiene rubber which contains specified carbon black reinforcement and silica together with a coupling agent. The tire tread rubber composition differs from the rubber composition of said sidewall lug and groove configuration by being exclusive of silica and coupling agent and carbon black reinforcement exclusive of said specified carbon black.

    摘要： This invention describes the use of liquid block isoprene-butadiene copolymers of approximately 25,000 to 100,000 .sub.v molecular weight, and which comprises 10 to 90% by weight isoprene and 90 to 10% by weight butadiene. This material is added to a rubber compound that contains natural rubber, isoprene rubber, styrene butadiene rubber and butadiene rubber, or blends thereof, the sum of which is equal to or greater than 50 phr of the entire rubber content formulation. The liquid block copolymer is used at low levels, typically 1.5 phr to 15 phr. The invention also includes tires with at least one component composed of such rubber composition such as a tire tread.
