The invention belongs to the field of
machine manufacturing, and particularly relates to a preparation method for high-performance and low-
thermogenesis SSBR rubber. The SSBR rubber is processed by SSBR 2305 base rubber, SSBR 312
rubber material, new
carbon black, auxiliary agents and a
vulcanization system, wherein the auxiliary agents comprise an anti-aging agent, an
accelerant, nano-Zno, A151, and Mg(OH)2; the SSBR 2305 base rubber and the SSBR 312
rubber material are mixed. The preparation method comprises the following steps: adding the auxiliary agents into the mixed rubber materials of the SSBR 2305 base rubber and the SSBR 312
rubber material and stirring for 35 min; adding 50 phr of the new
carbon black into the mixed rubber materials of the SSBR 2305 base rubber, the SSBR 312 rubber material and the auxiliary agents, and uniformly stirring; adding the mixed rubber materials of the SSBR 2305 base rubber, the SSBR 312 rubber material, the auxiliary agents and the new
carbon black into the
sulfur-free
vulcanization system to be subjected to
vulcanization for 50 minutes, wherein the temperature of the vulcanization
system is 150 DEG C. According to the invention, the production efficiency is high, the product percent of pass is high, the physical and mechanical properties are excellent, the low-
thermogenesis performance is excellent, and the application prospect is wide.
