Embodiment Construction
[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0020] A nanometer SSBR rubber processing method, characterized in that, the SSBR rubber is processed from SSBR2305 base rubber, SSBR312 rubber compound, new carbon black, auxiliary agent and vulcanization system, and the auxiliary agent includes: anti-aging agent, accelerator Agent, nano-ZnO, A151, Mg(OH) 2, nano flame retardant compound, described processing method comprises the following steps:
[0021] 1) Blending of SSBR2305 base rubber and SSBR312 rubber;
[0022] At a temperature of 140-155°C, mechanically stir and blend SSBR2305 base rubber and SSBR312 rubber in a ratio of 3-3.4:1, add auxiliary agents, and stir evenly for 35 minutes to produce a blended "rubber";
[0023] 2) At a temperature of 150°C, put 50 phr of new carbon black and n...
