High-wear-resistance conveyor belt cover rubber and preparation method thereof

The invention relates to high-wear-resistance conveyor belt cover rubber and a preparation method thereof. The high-wear-resistance conveyor belt cover rubber comprises the following components in parts by weight: 100 parts of rubber, 45-65 parts of a reinforcing agent, 1-5 parts of nano-zinc oxide, 0.5-3 parts of stearic acid, 2-5 parts of an anti-aging agent, 0.1-1 part of sulfur and 2-5 parts of an accelerant. The raw materials are subjected to first-stage mixing, second-stage mixing and vulcanization tabletting to prepare the high-wear-resistance conveyor belt cover rubber. The high-wear-resistance conveyor belt cover rubber is applied to fabric core and steel wire rope core conveyor belts, so that the conveyor belt product has excellent wear resistance while maintaining good physical and mechanical properties, the service life of the conveyor belt can be greatly prolonged, the replacement frequency is reduced, the cost is saved, and the production efficiency is improved. 本发明涉及一种高耐磨输送带覆盖胶及其制备方法，其配方比例按重量份计
