Problems solved by technology

[0002] The hoist belt is the main working part of the hoist, and its service life greatly affects the production efficiency
The materials conveyed by cement and other industries have the characteristics of high temperature, and the core rubber of general steel mesh belts mainly choose natural rubber and styrene-butadiene rubber with better adhesion and process performance, but these two rubbers have poor heat resistance , used in high temperature environment is prone to degradation, aging, cracking, resulting in a sharp drop in the adhesive force value between the core rubber and the skeleton material, the hopper bolts come out of the steel mesh belt and other consequences, which seriously affect the service life of the steel mesh belt

Abstract

The invention relates to core rubber for a high temperature resistance steel mesh elevator belt and a preparation method of the core rubber, and belongs to the technical field of covering rubber. The core rubber comprises 100 parts by weight of ethylene-propylene rubber, 60-100 parts by weight of reinforcing filler, 3.2-4.8 parts by weight of vulcanizing agent, 8-10 parts by weight of vulcanizing activator, 25-32 parts by weight of plasticizer, 3-5 parts by weight of anti-aging agent and 3.5-4.5 parts by weight of adhesive. The core rubber for the high temperature resistance steel mesh elevator belt is prepared by primary mixing and secondary mixing of the components. After the core rubber for the high temperature resistance steel mesh elevator belt is used, the conveying requirements of high-temperature materials in cement plans are satisfied, the premature aging and fracturing of the core rubber, and the substantial reduction of adhesive force of the core rubber on a steel mesh, which is caused by aging of the core rubber, can be effectively prevented, a hopper bolt is effectively prevented from coming off from the steel mesh elevator belt, the service life of the high temperature resistance steel mesh elevator belt is greatly prolonged, and very good economic benefits are achieved.
