The invention provides a tread rubber composition and a preparation method thereof, and belongs to the technical field of rubber tire preparation, the tread rubber composition comprises matrix rubber, carbon black, white carbon black, tire filler and sulfur; the tire filler is a modified carbon black L-727 filler; the modified carbon black L-727 filler is a reinforcing filler obtained by mixing a carbon nano tube and borane and then grafting modified carbon black. The wet skid resistance of a tire prepared from the tread rubber composition is remarkably improved, the rolling resistance of the tire is reduced, the oil consumption per hundred kilometers can be reduced by 2-3%, low carbon and environmental protection are facilitated, the comfort is improved, and the braking distance is improved.

    本发明提出一种胎面橡胶组合物及其制备方法,属于橡胶轮胎制备技术领域,包括基体橡胶、炭黑、白炭黑、轮胎填料、硫磺;所述轮胎填料为改性炭黑类L‑727填料;所述改性炭黑类L‑727填料为碳纳米管及硼烷混合后接枝改性炭黑得到的补强填料。通过本发明中的胎面橡胶组合物制得的轮胎抗湿滑性能显著提升,轮胎滚动阻力降低,百公里油耗可以减少2%‑3%,利于低碳环保,舒适性提升,制动距离得到改善。
