Abstract

The present invention discloses a rubber composition, a processing method thereof, and rubber product reinforced with silica using the same. The rubber composition comprises a rubber matrix and essential components, wherein, based on 100 parts by weight of the rubber matrix, the rubber matrix comprises, a branched polyethylene with a content represented as A, in which 0<A≤100, and an EPM and an EPDM with a total content represented as B, in which 0≤B<100; and the essential components comprise 1-10 parts of a crosslinking agent and 15-80 parts of silica. The rubber composition can be used for producing high-voltage insulating sheath rubber, high-temperature resistant conveyor belt, waterproof coil, rubber particles for plastic track surface layer, rubber plug, rubber roller, inner tube, tire tread, tire sidewall, and inner rubber layer of air-conditioner hose.
