The invention relates to the technical field of new materials for tire manufacturing, and especially relates to a tire tread rubber composition, a mixing method thereof, and a low-rolling-resistance all-steel radial tire. The tire tread rubber composition is prepared by mixing the following raw materials: 100 phr of raw rubber, 35 to 50 phr of carbon black, 5 to 15 phr of silica powder, 1.0 to 2.0 phr of a silane coupling agent and 0.2 to 0.8 phr of organic thiophosphate. The new silica powder is coupled with the silane and the organic thiophosphate to be used in the all-steel radial tire tread formula, the heat generation characteristic is lower than that of white carbon black, meanwhile, the problem that the white carbon black is difficult to disperse is solved, the rubber processability is improved, meanwhile, the abrasion performance loss is small, the specific gravity is light, oil is saved, a the price is low, industrial production is facilitated, and the economic value is comprehensively improved.

    本发明涉及轮胎制造新材料技术领域,具体涉及一种轮胎胎面胶料组合物及其混炼方法和低滚阻全钢子午线轮胎。一种轮胎胎面胶料组合物,该组合物由包括以下组分的原料混炼制得:生胶100phr,炭黑35‑50phr,硅格粉5‑15phr,硅烷偶联剂1.0‑2.0phr,有机硫代磷酸盐0.2‑0.8phr。本发明优势主要体现在,将新硅格粉与硅烷、有机硫代磷酸盐偶联用于全钢子午线轮胎胎面配方,在具有比白炭黑更低生热特性的同时,克服了使用白炭黑分散困难问题,提高胶料加工性能的同时磨耗性能损失较小,并且比重轻,节油,价格低廉,有利于工业化生产,经济价值综合提升。
