Problems solved by technology

In addition, some companies use the combination of natural rubber and styrene-butadiene rubber as the rubber matrix of the adhesive layer. Although the adhesive performance is well improved, its resistance to heat, oxygen, and air aging is not good, and rubber and canvas are prone to appear during use. delamination
[0004] The above-mentioned technologies have improved the adhesive properties of EPDM rubber to a certain extent, but there are also some problems: the combination of EPDM rubber and natural rubber and the combination of natural rubber and styrene-butadiene rubber reduce the aging performance and reduce the The service life is improved; the combination of EPDM rubber and halogenated butyl rubber improves the adhesion performance and has good heat resistance, but the price of halogenated butyl rubber is usually about twice that of EPDM rubber , thus increasing the cost of

Abstract

The invention relates to an adhesive coating rubber material for a high temperature resistant canvas conveyer and a use method thereof. In the adhesive coating rubber material, ethylene-propylene-diene rubber is used as a substrate and an unsaturated carboxylic metal salt filling material and a proper auxiliary are added, so that the adhesion property of rubber and a canvas conveyer core is improved; and at the same time, the thermal ageing resisting property of the adhesive coating rubber is also improved, so that the conveyer can endure the temperature of more than 175 DEG C for a long timewithout delaminating phenomenon, thereby prolonging the service life of the conveyer.

Description

technical field [0001] The invention relates to an adhesive layer rubber material for a high-temperature-resistant canvas conveyor belt and a use method thereof. Background technique [0002] High temperature resistant conveyor belt is made of multi-layer rubber cotton sail (polyester cotton cloth) or polyester canvas covered with high temperature resistant or heat resistant rubber, bonded together by high temperature vulcanization, widely used in metallurgy, casting, sintering, coking, building materials, etc. The relatively harsh high-temperature working environment in the industry mainly transports high-temperature solid materials produced in the production process such as sintered ore, coke and cement. Due to insufficient cooling of sintered materials, the temperature of the materials can reach 400-600 °C instantly, and some of them can reach above 800 °C. Therefore, it is required that the conveyor belt material must be resistant to high temperature [World Rubber Indust...
