Abstract

The present invention discloses a wear-resistant flame-retardant conveying belt, wherein the raw materials comprise, by weight, 22-25 parts of ethylene propylene diene monomer, 15-18 parts of chloroprene rubber, 10-15 parts of nitrile butadiene rubber, 8-12 parts of chlorinated polyethylene, 4-6 parts of carbon black, 7-10 parts of sulfur, 3-5 parts of a phosphorus-containing flame retardant agent, 0.6-0.8 part of dibenzothiazole disulfide, 1.2-1.5 parts of a composite stabilizer, 0.8-1 part of n-isopropyl-n'-phenyl p-phenylenediamine, 2-3 parts of an anti-aging agent, 0.5-0.7 part of a dispersant, 6-9 parts of an adhesive, 2-4 parts of a plasticizer, 6-8 parts of asbestos fiber, 8-10 parts of dioctyl phthalate, 16-18 parts of a reinforcing filler, 3-5 parts of a sulfamide accelerator, and0.5-0.8 part of stearic acid. According to the present invention, the wear-resistant flame retardant conveying belt has advantages of high conveying efficiency and good surface elasticity; the tensile strength of the prepared stretching-resistant and wear-resistant flame-retardant conveying belt covering glue is increased by 13.6% and the wear resistance is improved by 39% compared to the existing products; and the wear-resistant flame retardant conveying belt has advantages of good fire resistance, strength improving, high elongation, and long service life.

Description

technical field [0001] The invention belongs to the technical field of conveyor belts, in particular to wear-resistant and flame-resistant conveyor belts. Background technique [0002] The conveyor belt is suitable for material transportation in coal, mining, port, electric power, metallurgy, building materials and other industries. It has high tensile strength, long service life, small elongation in use, and good flex resistance. Capacity and high speed material conveying. High temperature resistant conveyor belt, also known as heat resistant conveyor belt, is a special heavy conveyor belt, mainly used for conveying high temperature materials in steel, cement, coke and other industries. The high-temperature-resistant conveyor belt with metal material as the skeleton layer has better burning resistance and is suitable for use at higher temperatures, such as 300°C. Therefore, the high-temperature-resistant conveyor belt with metal material as the skeleton layer is also calle...
