    • Provided are a rubber composition which is improved in dispersion of silica into a rubber composition and improved in both of a low heat build-up and abrasion resistance and which is suitable as a tire tread member and a tire prepared by using the same.In a rubber composition compounded with precipitated silica, a cetyltrimethylammonium bromide-adsorbing specific surface area (CTAB) (m2/g) and the mode Aac (nm) in diameters of primary aggregates determined by acoustic measurement of particle size distribution satisfy equation (I) shown below: Aac≧−0.76×(CTAB)+274 and further an ignition loss (mass reduction % when heated at 750° C. for 3 hours) and a heating loss (mass reduction % when heated at 105° C. for 2 hours) satisfy equation (II) shown below: (ignition loss)−(heating loss)≦3.
    • 提供一种橡胶组合物,其改进了二氧化硅在橡胶组合物中的分散性,并且在低发热性和耐磨性方面都得到改善,并且适合作为轮胎胎面部件和使用该胎面部件而制备的轮胎。 在与沉淀二氧化硅混合的橡胶组合物中,通过粒度分布的声学测定确定的一次聚集体直径的十六烷基三甲基溴化铵 - 吸附比表面积(CTAB)(m2 / g)和直径Aac(nm)满足式(I) 如下所示:Aac≧-0.76×(CTAB)+274,另外灼烧损失(在750℃下加热3小时时的质量减少%)和加热损失(在105℃下加热2次时的质量减少% 小时)满足以下所示的式(II):(点火损失) - (加热损失)≦̸ 3。
