The invention provides an epoxidized natural rubber composition, a preparation method thereof and tread rubber. The rubber material is prepared from the following raw materials: epoxidized natural rubber, other epoxidized rubber, a filler, an activator, an anti-aging agent, a plasticizer, an accelerant and a vulcanizing agent, based on the total amount of epoxidized natural rubber and other epoxidized rubber as 100 parts by weight, the composition comprises 50-95 parts by weight of epoxidized natural rubber; preferably, 60-90 parts by weight; 5-50 parts by weight of other epoxidized rubber; and preferably, 10-40 parts by weight of the composition. The preparation method of the epoxidized natural rubber is improved, the preparation process is simplified, and the prepared epoxidized natural rubber composition can be used for preparing all-steel radial tire treads.

    本发明提供了一种环氧化天然橡胶组合物及其制备方法和胎面胶。由包括环氧化天然橡胶、其他环氧化橡胶、填料、活化剂、防老剂、增塑剂、促进剂和硫化剂的原料制备而得;以环氧化天然橡胶与其他环氧化橡胶的总量为100重量份计,包括环氧化天然橡胶50~95重量份;优选60~90重量份;其他环氧化橡胶5~50重量份;优选10~40重量份。本发明改进了环氧化天然橡胶的制备方法,简化了制备工艺,制备的环氧化天然橡胶组合物可以用于制备全钢子午线轮胎胎面。
