The invention relates to the technical field of tire manufacturing, in particular to a low-rolling-resistance and high-wear-resistance tire tread rubber composition, a mixing method and a tire. The invention relates to a tire tread rubber composition with low rolling resistance and high wear resistance. The composition is prepared by mixing the following raw materials in terms of 100 parts by weight of a raw rubber component: 100 phr of raw rubber, 50-130 phr of white carbon black and 3.0-10.0 phr of a silane coupling agent, the silane coupling agent is composed of a silane coupling agent I and a silane coupling agent II, and the mass ratio of the silane coupling agent I to the silane coupling agent II is (15-50): (50-85). Wherein the silane coupling agent I is 3-mercaptopropyltriethoxysilane and/or 3-mercaptopropyltrimethoxysilane, and the silane coupling agent II is 3-mercaptopropyltriethoxysilane and/or 3-mercaptopropyltrimethoxysilane; and the silane coupling agent II is 3-octanoyl thio-1-propyltriethoxysilane, and the silane coupling agent II is 3-octanoyl thio-1-propyltriethoxysilane. According to the composition, silane is optimized, and the dosage of the silane is regulated and controlled for compounding, so that the tread rubber composition which is relatively excellent in abrasion and relatively balanced in wet skid resistance and rolling resistance is obtained.

    本发明涉及轮胎制造技术领域,尤其涉及一种低滚阻高耐磨的轮胎胎面胶组合物、混炼方法和轮胎。一种低滚阻高耐磨的轮胎胎面胶组合物,该组合物按生胶组分为100重量份计由包括以下组分的原料混炼制备得到:生胶100phr,白炭黑50‑130phr,硅烷偶联剂3.0‑10.0phr;所述的硅烷偶联剂I和硅烷偶联剂Ⅱ构成,硅烷偶联剂I和硅烷偶联剂Ⅱ的质量比为(15‑50):(50‑85);其中硅烷偶联剂I为3‑巯丙基三乙氧基硅烷和/或3‑巯丙基三甲氧基硅烷;硅烷偶联剂Ⅱ为3‑辛酰基硫代‑1‑丙基三乙氧基硅烷。该组合物通过优选硅烷并对硅烷用量进行调控复配,来获得一种较优磨耗、抗湿滑和滚动阻力较为平衡的胎面橡胶组合物。
