Wear-resistant and flame-retardant conveyor belt and preparation method thereof

Abstract

The invention discloses a wear-resistant and flame-retardant conveyor belt and its preparation method, belonging to the technical field of conveyor belts. The wear-resistant and flame-retardant conveyor belt uses a wear-resistant and flame-retardant conveyor belt covering rubber as the covering rubber. The raw materials of the wear-resistant and flame-retardant conveyor belt covering rubber include: 20-30 parts of ethylene-propylene-diene monomer (EPDM) rubber, 30-40 parts of styrene-butadiene rubber (SBR), 30-40 parts of chlorosulfonated polyethylene rubber, 20-30 parts of super abrasion furnace black, 30-40 parts of silica, 15-20 parts of chlorinated paraffin, 3-5 parts of nano-activated zinc oxide, 2-6 parts of dispersant, 1-3 parts of sulfur, 2-6 parts of accelerator, 2-4 parts of anti-aging agent, 5-8 parts of microcrystalline wax, 2-3 parts of stearic acid, 15-20 parts of modified expandable graphite, 10-15 parts of modified silicon nitride and 10-15 parts of fluoropolymer. The above components cooperate synergistically, enabling the covering rubber to have excellent wear resistance and flame retardancy, thereby making the conveyor belt prepared by using the covering rubber have excellent wear resistance and flame retardancy.
