High-temperature-resisting conveying belt of steel wire rope

Abstract

The invention discloses a high-temperature-resisting conveying belt of a steel wire rope and solves the problem that the conveying belt of the existing steel wire rope core can not resist high temperature. According to the high-temperature-resisting conveying belt of the steel wire rope, the formula of rubber materials of upper and lower covered rubber layers comprises the following components in parts by weight: 70-80 parts of ethylene propylene diene monomer, 20-30 parts of chlorosulfonated polyethylene rubber or chlorinated polyethylene rubber or acrylate rubber, 6-8 parts of dicumyl peroxide, 0.5-1.5 parts of sulfur, 10-15 parts of zinc oxide, 1-3 parts of ethylene dimethyl acrylate ester, 1-2 parts of stearic acid, 2-8 parts of an accelerating agent, 2-4 parts of an anti-ageing agent, 15-25 parts of paraffin oil, 20-30 parts of high-wear-resisting carbon black, 30-50 parts of semi-reinforcing carbon black and 10-15 parts of active glass fiber powder. A glass fiber canvas heat-insulating layer is arranged between a middle rubber layer and an upper covered rubber layer, and a glass fiber canvas heat-insulating layer is arranged between the middle rubber layer and a lower covered rubber layer. The high-temperature-resisting conveying belt of the steel wire rope can be used under an environment of 250 DEG C for long time and the conveying requirements of some special high-temperature materials are met.

Description

technical field [0001] The invention relates to a high temperature resistant conveyor belt, in particular to a steel cord core high temperature resistant conveyor belt with a glass fiber canvas heat insulation layer. Background technique [0002] Steel cord high temperature resistant conveyor belt is mainly used in metallurgy, building materials, chemical industry and other industries to transport sintered ore, pelletized ore, cement clinker, lime, coke, fertilizer and other high temperature materials. The high temperature resistant conveyor belt with steel cord core in the prior art is composed of steel cord, intermediate rubber and upper and lower covering rubber. It has the advantages of large load capacity, long conveying distance and small tensile deformation. The disadvantage is poor high temperature resistance and short service life. When the operating temperature exceeds 150°C, the service life drops sharply. The main reasons are that the covering rubber foams, crac...

AI Technical Summary

Problems solved by technology

Since the high-temperature materials in metallurgy, building materials and other industries are all above 200°C, even exceeding 300°C or higher, the existing high-temperature-resistant steel cord conveyor belts can no longer meet the requirements for safe and economical transportation of high-temperature materials.
