The invention belongs to the field of rubber materials and preparation thereof, and particularly relates to an off-road vehicle tire tread rubber composite material and a preparation method thereof. The invention aims to solve the technical problem that the existing rubber composite material cannot meet the requirement of off-road vehicle tires on the comprehensive performance of tread rubber. The material is prepared from olefin rubber, epoxidized butadiene-isoprene rubber, sulfur and a functional additive, the olefin rubber is formed by mixing natural rubber and butadiene-isoprene rubber, the molecular weight of the butadiene-isoprene rubber is 60-90 w, Tg is-30 DEG C to-10 DEG C, the total content of vinyl and allyl is 40-60%, and the epoxy degree of the epoxidized butadiene-isoprene rubber is 80-95%. The wear resistance and the wet skid resistance of the tire are effectively improved, meanwhile, the rolling resistance is not affected, and the comprehensive performance is excellent.
本发明属于橡胶材料及其制备领域,具体涉及一种越野车胎胎面橡胶复合材料及其制备方法。本发明的目的是为了解决现有橡胶复合材料无法满足越野车胎对于胎面胶综合性能要求的技术问题。本发明的材料由烯烃类橡胶、环氧化丁戊橡胶、硫磺和功能助剂制备而成,烯烃类橡胶由天然橡胶和丁戊橡胶混合而成,丁戊橡胶分子量在60~90w,Tg为‑30℃~‑10℃,乙烯基和丙烯基总含量为40~60%,环氧化丁戊橡胶环氧度为80~95%。本发明既有效提高了轮胎的耐磨性能和抗湿滑性能,同时又不影响滚动阻力,综合性能优异。
