Rubber composition, vulcanized rubber, and applications vulcanized rubber

The present invention relates to the field of rubbers, and specifically discloses a rubber composition, a vulcanized rubber, and applications of the vulcanized rubber, wherein the rubber composition comprises a diene rubber and carbon black, and the diene rubber is a mixture of a styrene-isoprene copolymer and a butadiene rubber. According to the present invention, the rubber composition has high strength, is not easily degraded during the mixing process, has good carbon black dispersing property, can maintain good mechanical and physical property during the mixing process, does not easily produce heat during the mixing process, has low elasticity during the processing, and is easy to mold; and the vulcanized rubber has advantages of high strength, good physical mechanical property, low heat production loss, excellent wet skid resistance, and excellent wear resistance, and is particularly suitable for the tire tread rubber. 本发明涉及橡胶领域，具体公开了种橡胶组合物和硫化橡胶及其应用。所述橡胶组合物含有二烯烃橡胶和炭黑，其中，所述二烯烃橡胶为苯乙烯-异戊二烯共聚物和丁二烯橡胶的混合物。本发明的
