Ultrawear-resistant PVG flame-retardant conveying belt cover rubber

Abstract

The invention discloses ultrawear-resistant PVG flame-retardant conveying belt cover rubber and belongs to the field of conveying belts. The ultrawear-resistant PVG flame-retardant conveying belt cover rubber is composed of the following components in parts by weight: 95-105 parts of SG-3 resin, 15-25 parts of dioctyl phthalate, 20-30 parts of tris(2-chloroethyl) phosphate, 2-4 parts of tribasic lead sulfate, 4-6 parts of dibasic lead phosphite, 13-18 parts of triaryl phosphate, 5-9 parts of tetrapropylene titanate, 3-7 parts of antimony trioxide, 13-17 parts of chlorinated paraffin-52, 3-4 parts of zinc borate hydrate, 1-3 parts of silane coupling agent and 1-3 parts of dicumyl peroxide. The ultrawear-resistant PVG flame-retardant conveying belt cover rubber provided by the invention hasthe characteristics such as high strength, large transportation volume and transportation balance, and meanwhile, the ultrawear-resistant PVG flame-retardant conveying belt cover rubber has the performances such as good flame retardance, anti-static property, shock resistance, wear resistance and corrosion resistance, high strength and excellent safety performance and the characteristics such as lower cost and lower price as comparison with other flame-retardant conveying belts.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a super wear-resistant PVG flame-retardant conveyor belt cover glue. Background technique [0002] Conveyor belts are an indispensable tool in material transportation industries such as mines, power plants, coal, and docks, and their continuity and high efficiency play a huge role. At the same time, due to the increase in the current conveying volume, the large transport capacity and long transport distance of the steel wire rope conveyor belt are also gradually significant. But at the same time, the conveyor belt is affected by the material during operation, and the long-term contact and friction with the conveyor roller and the material will cause the conveyor belt covering rubber to be non-wearable and easy to fall off, resulting in frequent maintenance and short life. Therefore, the operating cost is higher, and the scrapped conveyor belt cannot be reused. Prolonging...

AI Technical Summary

Problems solved by technology

Although they are 120-150mm larger than conventional conveyor belts 3 The Shao Boer wear index has been reduced to a certain extent, but the wear index is still high, the service life of the conveyor belt is still short, and the operating cost is high

[0004] At the same time, because most of the materials are inflammable, the fire scene becomes a source of smoke, poisonous gas and heat energy

This not only brings great fire hazards to people's safety and quality of life and property, but also greatly limits the application in special fields with high fire protection requirements (such as public places, commercial places, entertainment, educational places and other crowded places furniture) Material)
