Abstract

The invention relates to an ablation-resistant anti-aging cover for conveying belt and preparation method thereof which belongs to the technological field of rubber conveying belt production. The preparation comprises the steps of: first mixing the EPDM, reinforcing filler, vulcanization active agent, plasticizer, antioxidant, ablative fiber, flame retardant, charcoal and compatibilizer together to acquire the mixed rubber, then adding the vulcanizing agent and co-crosslinking agent for the secondary mixing, and vulcanizing to obtain the product of ablation-resistant anti-aging cover for conveying belt. With the use of ablation-resistant anti-aging cover provided by the present invention the service life of the conveyor belt under high heat and open fire condition is dramatically prolonged, which guarantees the sustainable production of the enterprises and saves the costs and brings huge economic benefits.

Description

technical field [0001] The invention relates to an ablation-resistant and aging-resistant conveyor belt covering rubber and a preparation method thereof. The prepared product has excellent ablation resistance and aging resistance, and belongs to the technical field of rubber conveyor belt products. Background technique [0002] Ablation-resistant materials can be divided into three types according to the mechanism: sublimation type, melting type and carbonization type. Sublimation materials mainly rely on sublimation gasification at high temperature to absorb heat energy; melting materials mainly rely on melting and absorbing heat at high temperatures, and further form a molten liquid layer to block heat flow; and the excellent ablation performance of carbonization materials mainly depends on its surface. The carbonized layer formed at high temperature can largely prevent the transfer of external heat to the inside of the material, and can transfer a large amount of heat ene...
