Formula and processing technology of environment-friendly high temperature resistant fabric core rubber conveyor belt

Abstract

The invention discloses a formula of an environment-friendly high-temperature-resisting fabric core rubber conveyer belt and a processing technology, and aims to provide the formula of the environment-friendly high-temperature-resisting fabric core rubber conveyer belt which is simple in structure, convenient to use and small in odour, and the processing technology. The formula comprises cover rubber and adhesive rubber. The obtained environment-friendly high-temperature-resisting fabric core rubber conveyer belt has the advantages of superior high-temperature resistance, high high-temperature fatigue performance, high adhesion property and ageing property, and low possibility of ply separation blisters, and has small odour as compared with a conventional high-temperature-resisting rubber conveyer belt, and the conveyer belt can resist the test temperature of not higher than 180 DEG C, and has the highest short-time operation temperature of 450 DEG C, thereby meeting the international standard ISO4195 requirement.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to the formulation and processing technology of an environment-friendly high temperature resistant fabric core rubber conveyor belt. Background technique [0002] With the rapid development of science and technology and the continuous improvement of mechanical automation level, the performance requirements of conveyor belts are also getting higher and higher. [0003] At present, the fabric core of the rubber conveyor belt is mainly composed of cotton fiber, polyester fiber and nylon fiber. Among them, cotton fiber has high wet strength and low elongation, so it has good adhesion to rubber, but its high temperature resistance Poor, the current usage is decreasing day by day; polyester fiber has higher strength, better elasticity, wear resistance, chemical resistance, heat resistance and thermal stability, but its performance in the air at 150 ℃ After 168 hours of medium heating, the strength loss...

Problems solved by technology

[0003] At present, the fabric core of rubber conveyor belt is mainly composed of cotton fiber, polyester fiber and nylon fiber. Among them, cotton fiber has high wet strength and low elongation, so it has good adhesion to rubber, but its high temperature resistance Poor, the current usage is decreasing day by day; polyester fiber has higher strength, better elasticity, wear resistance, chemical resistance, heat resistance and thermal stability, but its performance in the air at 150 ℃ After 168 hours of medium heating, the strength loss is 15-30%, and after heating for 1000 hours, the strength loss is 50%. Nylon fibers have high strength, impact resistance, and fatigue resistance. The inner layer has poor high temperature resistance, and air bubbles are likely to be generated at the fabric core under high temperature, thus accelerating the aging of the conveyor belt and reducing the service life of the conveyor belt
