The invention discloses a self-cleaning light-color sidewall rubber composition which comprises 5.0-35.0 parts of natural rubber, 40.0-70.0 parts of brominated isobutylene p-methylstyrene rubber, 10.0-40.0 parts of ethylene propylene diene monomer, 20.0-60.0 parts of kaolin, 20.0-60.0 parts of titanium dioxide, 0.5-3.0 parts of ultramarine, 0.5-2.0 parts of stearic acid, 2.0-4.0 parts of a chemical antioxidant, 1.0-10.0 parts of nano-zinc oxide, 0.5-3.0 parts of a vulcanizing agent, and 2.0-5.0 parts of anaccelerant. Through adjustment of a raw rubber system and a protection system, the self-cleaning function of the light-color sidewall rubber composition is realized by utilizing a phenomenon that a surface layer is easy to fall off due to slight ozone aging while conventional physical andmechanical performance requirements such as aging resistance and the like is guaranteed.

    本发明公开了一种自清洁的浅色胎侧橡胶组合物,包括天然橡胶5.0~35.0份,溴化异丁烯‑对甲基苯乙烯橡胶40.0~70.0份,三元乙丙橡胶10.0~40.0份,高岭土20.0~60.0份,二氧化钛20.0~60.0份,群青0.5~3.0份,硬脂酸0.5~2.0份,化学防老剂2.0~4.0份,纳米氧化锌1.0~10.0份,硫化剂0.5~3.0份,促进剂2.0~5.0份。通过对生胶体系和防护体系的调整,使得浅色胎侧橡胶组合物在保证耐老化等常规物理机械性能需求的同时,利用轻微的臭氧老化所导致的表层易脱落现象来实现浅色橡胶组合物的自清洁功能。
