The invention relates to a low-rolling-resistance tread rubber composition and a preparation method thereof. The rubber composition comprises the following raw materials in parts by weight: 10-20 parts of carbon black N234 and 60-70 parts of precipitated white carbon black HD165MP, wherein the matrix rubber is 20-30 parts of natural rubber TSR20/STR20, 70-80 parts of non-oil-extended solution polymerized styrene butadiene rubber SSBR, 9.6-11.2 parts of bis [gamma (triethoxysilyl) propyl] tetrasulfide Si69, 1-2 parts of microcrystalline wax Antilux111, 2-3 parts of zinc oxide ZnO, 2-3 parts ofstearic acid SAD, 10-20 parts of environment-friendly aromatic oil V700 and 0.3-1.1 parts of a low rolling resistance modifier OCST. According to the invention, through the application of the low-rolling-resistance modifier OCST, the high-dispersity precipitated white carbon black is well dispersed in a non-oil-extended solution polymerized styrene-butadiene rubber SSBR (mark number NS615) matrix.
本发明涉及一种低滚动阻力胎面橡胶组合物及其制备方法。橡胶组合物,包括以下重量份数的原料:炭黑N234:10~20份,沉淀法白炭黑HD165MP 60~70份,其中基体橡胶为天然橡胶TSR20/STR20:20~30份,非充油溶聚丁苯橡胶SSBR:70~80份,双‑[γ‑(三乙氧基硅)丙基]四硫化物Si69:9.6~11.2份,微晶蜡Antilux111:1~2份,氧化锌ZnO:2~3份,硬脂酸SAD:2~3份,环保型芳烃油V700:10~20份,低滚阻改性剂OCST:0.3~1.1份。本发明通过低滚阻改性剂OCST的运用,高分散性沉淀法白炭黑在非充油溶聚丁苯橡胶SSBR(牌号NS616)基体中获得良好的分散。
