发明名称 Rubber prepared with precipitated silica and carbon black pellet composites of controlled hardness and tire with component derived therefrom
摘要 This invention relates to a rubber composition prepared with reinforcement comprised of a combination of precipitated silica aggregates and pelletized rubber reinforcing carbon black composites of carbon black and organic binder of a controlled hardness and to a tire with at least one component comprised of and derived from such rubber composition in which said carbon black pellet composites are disintegrated (fragmented) in situ within said rubber composition in the presence of particulate precipitated silica and silica coupling agent. In one aspect the invention relates to a tire having a component of a rubber composition comprised of at least one conjugated diene-based elastomer and reinforcing filler comprised of a combination of precipitated silica, silica coupling agent and fragmented rubber reinforcing carbon black pellet composites, said pellets having a controlled hardness value.
