The invention provides an acid-alkali-resistant heat-resistant aramid rope conveying belt and a preparation method thereof, and belongs to the technical field of conveying belt preparation. The acid-base-resistant heat-resistant aramid rope conveying belt comprises the following raw materials: 30-40 parts of styrene butadiene rubber, 50-80 parts of ethylene propylene diene monomer, 20-40 parts of chloroprene rubber, 3-15 parts of epoxy resin, 2-10 parts of modified graphene, 30-70 parts of white carbon black, 8-15 parts of softening oil, 5-12 parts of basalt fiber, 2-6 parts of sulfur, 1-3 parts of an accelerant and 4-7 parts of an anti-aging agent. The epoxy resin, the modified graphene and the basalt fibers are added into the rubber, so that the acid and alkali resistance of the aramid rope conveying belt is improved through the combined action of the epoxy resin, the modified graphene and the basalt fibers. 本发明提供了一种耐酸碱耐热芳纶绳输送带及其制备方法，属于输送带制备技术领域。本发明的耐酸碱耐热芳纶绳输送带的原料组成为：丁苯橡胶30～40份、三元乙丙橡胶50～80份、氯丁橡胶20～40份、环氧树脂3
