Abstract

The invention provides a flame-retardant antistatic rubber material for a conveying belt covering layer and a preparation method of the rubber material. The rubber material is composed of chloroprene rubber, butadiene styrene rubber, sulfure, carbon black, ethyl tri-(2-methoxyethoxy)silane, zinc stearate, promoter, antiager, dicyclopentadiene resin, octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate, trihydroxyethyl methyl quaternary ammonium methyl sulfate, stearamide propyl dimethyl-beta-ethoxy ammonium dihydrogen phosphate, aluminum hydroxide, bis(2, 3-dibromopropyl)fumaric acid and 1, 2-bis(2, 4, 6-tribromophenoxy) ethane. The rubber material is prepared through plastifying, two times of mixing and vulcanization. Due to uniform dispersion and high compatibility with polymer of an antistatic agent and a flame retardant in the rubber material in a polymer substrate, flame-retardant and antistatic effects of rubber are improved obviously.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a rubber material for a flame-retardant and antistatic conveyor belt covering layer and a preparation method thereof. Background technique [0002] As a simple and fast conveying tool, the conveyor belt is widely used in all walks of life, especially the rubber conveyor belt, especially the belt made of covered rubber material has good wear resistance and mechanical strength. The application in production is very extensive. my country's flame-retardant and antistatic rubber conveyor belt is centered on underground coal mines, providing safety guarantee for the use of underground coal mine conveyor belts. Rubber and plastic are high-resistivity materials that are easy to burn and accumulate static electricity. The surface resistivity of the material is as high as 10 13 Ω. This kind of material is easy to accumulate a large amount of static electricity when it rubs against or sep...
