Cold resistant and flame retardant antistatic conveyor belt cover rubber and conveyor belt

Abstract

The invention relates to a cold resistant and flame retardant antistatic conveyor belt cover rubber, which comprises the following components by weight: 35-50 parts of natural rubber, 40-60 parts of butadiene rubber, 20-30 parts of chloroprene rubber, 20-30 parts of conductive carbon black, 25-35 parts of high wear-resistant carbon black, 10-15 parts of antimony trioxide, 5-10 parts of chlorinatedparaffin, 8-15 parts of ammonium polyphosphate, 5-10 parts of a flame-retardant softener, 1-2 parts of a vulcanizing agent, 1-2 parts of a vulcanizing accelerator, 3-6 parts of zinc oxide, 1-2 partsof magnesium oxide, 10-16 parts of rare earth oxide, 1-2 parts of stearic acid, 2-4 parts of an anti-aging agent and 1-2 parts of an antioxidant. Conductive carbon black is added into the cover rubberprovided by the invention to increase the conductivity of the cover rubber layer and improve the antistatic ability, the antimony trioxide, chlorinated paraffin and ammonium polyphosphate play a flame retardant role, and at the same time through cooperation with the flame-retardant softener, the softness of the rubber crosslink bond is improved, thus making up for the deficiency of rubber elasticity in a flame retardant conveyor belt under chilly conditions.

Description

technical field [0001] The invention relates to a covering glue, in particular to a cold-resistant, flame-retardant and antistatic conveyor belt covering glue. Background technique [0002] Conveyor belts are widely used in agriculture, industrial and mining enterprises, and transportation to transport various solid block and powder materials or finished items. The conveyor belt can be transported continuously, efficiently, and at a large inclination angle. The belt is easy to use, easy to maintain, low in freight, can shorten the transportation distance, reduce the project cost, and save manpower and material resources. [0003] Conveyor belt, also called conveyor belt, is a composite product of rubber, fiber and metal, or a composite product of plastic and fabric, which is used to carry and transport materials in a belt conveyor. The belt conveyor is continuous, high-efficiency, and transported at a large inclination angle. It is safe to operate, easy to use, easy to main...
