The invention provides a rubber composition containing SSBR (Styrene Butadiene Rubber). Comprising 100-120 parts of solution polymerized styrene-butadiene rubber, 40-60 parts of butadiene rubber, 20-30 parts of polyurethane, 20-40 parts of a carbon black filler, 10-20 parts of white carbon black, 5-10 parts of tear-resistant resin, 8-12 parts of an anti-aging agent, 5-8 parts of sulfur, 10-20 parts of pine tar, 1-3 parts of a heat stabilizer, 3-5 parts of stearic acid, 1-3 parts of protective wax, 1-3 parts of an activator and 5-10 parts of modified epoxy resin, the modified epoxy resin is prepared from bisphenol A type epoxy resin, butadiene, acrylonitrile, 2-cyanoacrylate ethylene glycol monomethyl ether ester and acrylic acid, and a polyfunctional group polymer is prepared from the bisphenol A type epoxy resin, butadiene, acrylonitrile, 2-cyanoacrylate ethylene glycol monomethyl ether ester and acrylic acid. The SSBR-containing rubber composition provided by the invention has excellent tear strength and excellent wear resistance, and has better comprehensive performance compared with a comparative proportion.
