The invention provides a rubber composition for a tire tread, a rubber compound for the tire tread and a preparation method of the rubber compound. The rubber composition is prepared from the following components in parts by weight: 100 parts of rubber, 40 to 100 parts of carbon black, 0.5 to 15 parts of an anti-aging agent, 0.5 to 10 parts of an active agent, 0.2 to 5 parts of a vulcanizing agent, 0.2 to 5 parts of an accelerant and 4 to 20 parts of an auxiliary agent, the anti-aging agent comprises a p-phenylenediamine anti-aging agent, the p-phenylenediamine anti-aging agent is an anti-aging agent A with a structure as shown in a formula I and/or an anti-aging agent B with a structure as shown in a formula II, and a rubber compound prepared from the rubber composition above # imgabs0 # has excellent physical performance and anti-aging performance, is more suitable for tire tread production, is used for toxicological detection of rubber residues, and can be applied to tire tread production. And no high-toxicity quinone product is detected. Therefore, the rubber composition for the tire tread is environment-friendly and non-toxic, and has good environmental protection performance.
本发明提供了一种轮胎胎面用橡胶组合物、轮胎胎面用混炼胶及其制备方法。以重量份数计,该橡胶组合物包括:100份的橡胶、40~100份的炭黑、0.5~15份的防老剂、0.5~10份的活性剂、0.2~5份的硫化剂、0.2~5份的促进剂以及4~20份的助剂;防老剂包括对苯二胺类防老剂,对苯二胺类防老剂为式I所示结构的防老剂A和/或式II所示结构的防老剂B,#imgabs0#以上橡胶组合物制备得到的混炼胶具有优良的物理性能和耐老化性能,更适用于轮胎胎面生产,且对橡胶残留物进行毒理性检测,未检出高毒醌化产物。因此,本申请的轮胎胎面用橡胶组合物对环境友好无毒害,具有良好的环保性能。
