The invention belongs to the technical field of new materials for manufacturing rubber tires, and particularly relates to a white carbon black filled tread rubber composition, a mixing method thereof and a wear-resistant tire adopting the tread rubber composition. The invention relates to a white carbon black filled tread rubber composition, which is prepared by mixing the following raw materials in parts by weight: a rubber system, 70.0-80.0 parts by weight of white carbon black and 10-20 parts by weight of carbon black, wherein the rubber system consists of 100 parts by weight of emulsion polymerized styrene-butadiene rubber, solution polymerized styrene-butadiene rubber and polybutadiene rubber in total in terms of pure rubber. The rubber composition provided by the invention not only has wear resistance comparable to that of a carbon black formula, but also has better performance in the aspect of dynamic performance. The tire prepared from the rubber composition has more excellent wet grip performance and fuel economy while ensuring the mileage of the tire.

    本发明属于橡胶轮胎制造新材料技术领域,尤其涉及一种白炭黑填充胎面橡胶组合物及其混炼方法和采用该胎面橡胶组合物的耐磨轮胎。一种白炭黑填充胎面橡胶组合物,该橡胶组合物由包括以下组分的原料混炼制备得到:橡胶体系由以纯橡胶计乳聚丁苯橡胶+溶聚丁苯橡胶+聚丁二烯橡胶共计100重量份构成,白炭黑组分70.0‑80.0重量份,炭黑组分10‑20重量份。本发明橡胶组合物,既含有与炭黑配方媲美的耐磨性能,同时在动态性能方面具有更好的表现。使用此橡胶组合物制备的轮胎,在保证轮胎行驶里程的同时,具有更加优异的湿抓性能及燃油经济性。
