Firing resistant conveyer belt cover plastic and preparation method thereof

Abstract

The invention discloses firing resistant conveyer belt cover plastic and a preparation method thereof. The firing resistant conveyer belt cover plastic comprises the following components in parts by weight: 100 parts of vulcanizing silicone rubber, 20-70 parts of reinforcing filler, 0.5-5 parts of vulcanizing agent, 8-20 parts of vulcanizing activator, 10-35 parts of plasticizer, 3-6 parts of antiager and 15-45 parts of fire retardant. The preparation method comprises the following steps: first segment mixing, primary cooling, second segment mixing and secondary cooling. The firing resistant conveyer belt cover plastic disclosed by the invention can be used for a long time under an environment of 250-400 DEG C and can be instantly used at 600 DEG C for a short time, and can be used for preventing the phenomenon that a high temperature material cannot be normally transported induced by surface cracking, corrosion or carbonization of the cover plastic due to over high temperature and greatly prolonging the service life of the conveying belt at a high temperature to achieve a good economic benefit. The preparation method disclosed by the invention has the characteristics of simple steps and easiness in operation, and the like.

Description

technical field [0001] The invention discloses a burning-resistant conveyor belt covering glue, and also discloses a preparation method of the burning-resistant conveying belt covering glue. Background technique [0002] In recent years, the rapid development of China's economy has led to the continuous expansion of the production scale of steel, metallurgy, coke, cement and other industries, which requires continuous improvement of efficiency and steady growth of production capacity. put forward higher requirements. [0003] The materials transported by iron and steel, metallurgy, coke and cement generally have the characteristics of high temperature, the temperature reaches 200-400 ℃, and the instantaneous temperature even reaches 600 ℃, so the heat-resistant level of the covering rubber of the heat-resistant conveyor belt has high requirements. At present, the heat-resistant conveyor belt cover rubber on the market adopts heat-resistant grades up to T 3 ~T 4 The high-q...

Problems solved by technology

[0003] The materials transported by iron and steel, metallurgy, coke and cement generally have the characteristics of high temperature, the temperature reaches 200-400 ℃, and the instantaneous temperature even reaches 600 ℃, so the heat-resistant level of the covering rubber of the heat-resistant conveyor belt has high requirements. At present, the heat-resistant conveyor belt cover rubber on the market adopts heat-resistant grades up to T 3 ~T 4 The high-quality ethylene-propylene rubber can meet the transportation of general high-temperature materials, but during the transportation process, the surface of some high-temperature materials still has a phenomenon of red fire, so that the temperature of the material can reach 600 ° C. In this case, ethylene-propylene rubber is used as the main material. The surface of the main conveyor belt covering rubber is prone to cracks and erosion, which will affect the use of the conveyor belt and affect the material transportation of the user unit
