Problems solved by technology

The steel wire spiral mesh conveyor belt is composed of upper and lower covering rubber layers and steel wire spiral mesh skeleton; the application of the actual product strength is not the covering layer, but the steel wire spiral mesh. The upper and lower covering rubber layers on the steel wire spiral mesh are not flame retardant. and strong wear resistance, it will be burnt and polished in a short time, and the tightly arranged spiral mesh wires can continue to be used, but the long-term high temperature will quickly anneal and soften the steel wire, and then deform it scrapped, its anti-burning ability is poor, and its service life is short
Although the chain-plate conveyor belt can withstand high-temperature grilling and abrasion, it is rarely used in iron and steel enterprises due to the high initial cost, inconvenience of maintenance and installation, and long working hours.

Abstract

The invention discloses a rubber and plastic mixture module, which is prepared from the following raw materials in part by weight: 30 to 60 parts of chloroprene rubber, 10 to 25 parts of chlorinated polyethylene, 20 to 40 parts of butadiene styrene rubber, 25 to 35 parts of carbon black, 10 to 25 parts of composite reaction type flame retardant, 30 to 50 parts of phenolic resin, 3 to 8 parts of zinc oxide, 1 to 3 parts of light magnesia, 1 to 3 parts of stearic acid, 1 to 3 parts of vulcanizing agent, 1 to 5 parts of accelerating agent and 8 to 15 parts of liquid flame-retardant softener. The rubber and plastic mixture module serves as a tortoise shell conveyer belt for sintering an outer coating, and has high abrasion resistance, high-temperature resistance, burning resistance and flame combustion resistance, long service life, low cost and relatively low toxicity.

Description

Technical field [0001] The invention relates to a covering layer material of a conveyor belt and a manufacturing method thereof, in particular to a covering layer material of a high temperature resistant conveyor belt that works in a high temperature environment and a manufacturing method thereof. Background technique [0002] High temperature resistant conveyor belts are widely used in the transportation of hot materials in many important industrial fields such as metallurgy, casting, coking, building materials, and chemical industries. The temperature of the materials conveyed is sometimes very high, such as the sintered ore and hot pellets conveyed in the sintering workshop of steel plants. The temperature of high-temperature materials such as coke just out of the furnace can even reach thousands of degrees. At present, the high-grade heat-resistant conveyor belts used by domestic and international steel companies are generally steel spiral mesh heat-resistant conveyor belts a...
