Abstract

The invention discloses a high temperature resistant wire rope core flame-retardant conveying belt, and solves the problem that the conventional wire rope core flame-retardant conveying belt is not high temperature resistant. According to the invention, the sizing material of an upper covering bond layer as well as that of a lower covering bond layer comprise the following ingredients in part by weight: 30 to 50 parts of ethylene-propylene-diene rubber, 25 to 35 parts of chlorinated butyl rubber, chlorosulfonated polyethylene rubber or neoprene, 25 to 35 parts of chlorinated polyethylene rubber, 4 to 6 parts of dicumyl peroxide, 0.5 to 1.5 parts of sulfur, 0.5 to 1 part of tert-octylphenol-formaldehyde resin, 1 to 3 parts of epoxy resin, 8 to 12 parts of zinc oxide and/or magnesium oxide, 1 to 2 parts of stearic acid, 2 to 8 parts of accelerating agent, 2 to 4 parts of antiager, 8 to 15 parts of conductive carbon black, 25 to 45 parts of high abrasion resistant carbon black, 10 to 15 parts of active glass fiber powder, 20 to 50 parts of solid flame retardant, 10 to 20 parts of liquid flame retardant, and 3 to 8 parts of flame-retardant lubricant MB-202. Two glass fiber canvas thermal insulating layers are arranged between a middle bond layer and the upper covering bond layer and between the middle bond layer and the lower covering bond layer respectively. The high temperature resistant wire rope core flame-retardant conveying belt can be used for a long time at the temperature of 250 DEG C, and meets the conveying requirements of special high-temperature materials.

Description

technical field [0001] The invention relates to a steel cord conveyor belt, in particular to a high temperature resistant steel cord flame retardant conveyor belt. Background technique [0002] Steel cord conveyor belts are mainly used for heavy-duty, long-distance material transportation. The steel cord conveyor belts in the prior art mainly include general-purpose steel cord conveyor belts (GB / T9770-2001), steel cord flame-retardant conveyor belts for coal mines (MT668 -2008), the former is used for conveying common materials, neither flame retardant nor high temperature resistant. The latter is used for the transportation of coal underground in coal mines. It has flame retardant and antistatic properties, but it is not resistant to high temperatures. Sintered ore, pelletized ore, cement clinker, lime, coke, chemical fertilizer, etc. in metallurgy, building materials, chemical industry and other industries are all high-temperature materials, which can even ignite the conv...
