The invention aims to provide a rubber composition for an environment-friendly tire tread. According to the invention, polyether polyol is adopted to carry out anchoring modification on the surfaces of nano white carbon black particles, solution polymerized styrene-butadiene rubber slurry is acylated, the surfaces of the nano white carbon black particles are coated to form a barrier layer with high connection strength so as to separate the nano white carbon black particles, and finally direct mixing with solution polymerized styrene-butadiene rubber slurry and coagulating are performed to prepare the high-performance rubber composition for the tire tread. The method solves the problem that the nano white carbon black particles are easy to agglomerate under the conditions of long-term storage, high temperature and high shearing, improves the compatibility of the nano white carbon black and the solution polymerized styrene-butadiene rubber, and endows the nano white carbon black particles with high dispersity in the solution polymerized styrene-butadiene rubber matrix. The rubber composition has good wet skid resistance and low rolling resistance. The preparation method disclosed bythe invention is environment-friendly, simple, feasible and suitable for industrial production.
本发明目的在于提供一种绿色轮胎胎面用橡胶组合物,该发明采用聚醚多元醇对纳米白炭黑粒子表面进行锚固改性,而后对溶聚丁苯胶浆进行酰化处理,最后包覆在纳米白炭黑粒子表面形成一种连接强度高的阻碍层达到分离纳米白炭黑粒子,然后与溶聚丁苯胶浆直接混合、凝聚来制备出用于轮胎胎面的高性能橡胶组合物。这种方法不仅解决纳米白炭黑粒子因长期存放、高温、高剪切条件下易发生团聚的问题,而且还改善纳米白炭黑与溶聚丁苯橡胶的相容性,赋予纳米白炭黑粒子在溶聚丁苯橡胶基体中的高分散性。该橡胶组合物有好的抗湿滑性和低的滚动阻力。本发明的制备方法绿色环保,简单易行,适合工业化生产。
