The invention relates to the technical field of new materials for tire manufacturing, in particular to an all-season tire tread rubber composition with improved wet skid performance, a mixing method and a tire. According to the invention, a raw rubber system combining natural rubber and butadiene rubber is adopted, the reinforcing resin is adopted to reinforce the raw rubber system, the highly filled white carbon black is adopted, and the epoxidized natural rubber is added, so that the wet skid performance can be improved, the wet skid performance can be improved by 15-20% when the dosage is 1-10 phr, the rolling resistance is not increased, and the performance in winter is not deteriorated. The all-season tire tread rubber composition and the tire can be developed, and the tread rubber composition has wet performance, heat generation performance, winter performance and abrasion performance which are equivalent to those of solution polymerized styrene-butadiene with low glass transition temperature.

    本发明涉及轮胎制造新材料技术领域,尤其涉及一种改进湿滑性能的全季轮胎的胎面橡胶组合物、混炼方法和轮胎。本发明采用天然橡胶和顺丁橡胶并用的生胶体系,并采用补强树脂补强该生胶体系,同时采用高填充的白炭黑,同时加入了环氧化天然橡胶,可以改善湿滑性能,用量在1‑10phr的时候可以有15‑20%改善湿滑,滚阻不增加,冬季性能不恶化。能够开发出全季胎胎面橡胶组合物和轮胎,该胎面橡胶组合物具有与使用低玻璃化转变温度的溶聚丁苯相当的湿地性能、生热性能、冬季性能、磨耗性能。
