    摘要： An elastomeric composition is described which comprises at least one elastomeric component, at least one reinforcing filler, and at least one wet skid enhancing filler, for improving the wet skid resistance of the resultant composition. The wet skid enhancing filler is defined by a high Moh's hardness and large particle size. The resulting composition exhibits improved wet skid resistance compared to the same composition having no wet skid enhancing filler. Articles made from the elastomeric compositions are also described as well as methods of improving wet skid resistance and methods of making wet skid resistant materials.

    摘要： Disclosed are elastomeric compounds including an elastomer and a silicon-treated carbon black, and optionally including a coupling agent. The elastomeric compound exhibits poorer abrasion resistance in the absence of a coupling agent, lower hysteresis at high temperature and comparable or increased hysteresis at low temperature compared to an elastomer containing an untreated carbon black. A variety of elastomers and formulations employing such elastomers are contemplated and disclosed. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed are methods for preparing elastomers compounded with the treated carbon black.

    摘要： Novel elastomeric compositions are disclosed, incorporating silicon-treated carbon black and pre-vulcanization modifier selected from non-silane polysulfidic organo-compounds. The silicon-treated carbon black particulate filler differs chemically and in its performance characteristics from simple mixtures of silica and carbon black fillers. The pre-vulcanization modifier is effective to substantially increase bound rubber content in the product of a non-productive thermomechanical working of a base composition incorporating the silicon-treated carbon black particulate filler and SBR or other such unsaturated elastomer. The thermal working takes place at a maximum temperature sufficient to vulcanize the unsaturated elastomer if it were in the presence of a suitable vulcanization system. The non-vulcanized rubber masterbatch produced by such thermal working, having substantially increased bound rubber content, can be admixed with a vulcanization system in a thermomechanical finishing step carried out at a maximum temperature less than the vulcanization temperature. The resulting composition can be vulcanized by thermomechanical working at or above the vulcanization temperature. The resulting elastomeric compositions in accordance with preferred embodiments are found to have improved performance characteristics, including hysterisis balance of low temperature traction and high temperature rolling resistance.
