High-temperature-resistant and acid-alkali-resistant conveyor belt cover rubber and preparation method thereof

The invention relates to the technical field of conveying belts, and provides high-temperature-resistant and acid-alkali-resistant conveying belt cover rubber and a preparation method thereof. The conveyor belt cover rubber comprises the following components in parts by weight: 60-80 parts of butadiene styrene rubber, 20-30 parts of ethylene propylene diene monomer, 5-10 parts of epoxy resin, 3-5 parts of iso-tridecanol polyoxyethylene ether, 2-3 parts of nano silicon nitride, 30-50 parts of white carbon black, 15-20 parts of softening oil, 3-6 parts of zinc oxide, 1-2 parts of stearic acid, 3-6 parts of sulfur, 1-2 parts of an accelerant and 2-5 parts of an anti-aging agent. According to the technical scheme, the problem that the service life is shortened due to easy corrosion and abrasion of the surface of the conveying belt caused by poor acid and alkali resistance of the conveying belt cover rubber in the related technology is solved. 本发明涉及输送带技术领域，提出了一种耐高温耐酸碱用输送带覆盖胶及其制备方法。本发明的输送带覆盖胶，包括以下重量份的组分：丁苯橡胶60-80份，
