The invention provides a rubber composition for a tire sidewall, a rubber compound for the tire sidewall and a preparation method of the rubber compound. The rubber composition comprises the following components in parts by weight: 100 parts of rubber, 30-70 parts of carbon black, 2-20 parts of an anti-aging agent, 1-15 parts of an active agent, 0.5-4 parts of a vulcanizing agent, 0.5-6 parts of an accelerant and 1-10 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 with the number being # imgabs0 # or above has excellent physical performance and anti-aging performance and is more suitable for tire sidewall production. Besides, toxicity detection is carried out on rubber residues, and high-toxicity quinonized products are not detected after detection, so that the rubber composition for the tire sidewall is environment-friendly and non-toxic, and has good environmental protection performance.
本发明提供了一种轮胎胎侧用橡胶组合物、轮胎胎侧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、30~70份的炭黑、2~20份的防老剂、1~15份的活性剂、0.5~4份的硫化剂、0.5~6份的促进剂以及1~10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,更适用于轮胎胎侧生产。此外,通过对橡胶残留物进行毒理性检测,检测后未检出高毒醌化产物,因此,本发明的轮胎胎侧用橡胶组合物对环境友好无毒害,具有良好的环保性能。
