Abstract

A refractory conveying belt is prepared from the dibasic ethylene propylene rubber, or dibasic ethylene propylene rubber and ternary ethylene propylene rubber through pre-pugging, adding heat conducting agent and anti-ageing agent, pugging, adding reinforcing agent, softening agent and short aramid fibers, pugging, adding cross-linking agent and cross-linking aid, heating, calendering to become sheet, attaching it onto tension-resistant canvas, rolling and sulfurizing.

Description

technical field [0001] The invention relates to a high-temperature-resistant conveyor belt, which is specifically used in industries such as iron and steel, cement, and high-temperature sintered ore and cement clinker for operation and transportation, and belongs to the technical field of rubber products. Background technique [0002] At present, in the iron and steel, cement and other industries, the operation and transportation of high-temperature sintered ore and cement clinker are completed through high-temperature resistant conveyor belts. The high-temperature-resistant conveyor belt working surface covering rubber is mainly gradually added in batches on the internal mixer by using EPDM rubber, halogenated butyl rubber, styrene-butadiene rubber and cross-linking agent, reinforcing agent, softener and anti-aging agent. Through one-stage and two-stage mixing, it is processed into two-stage compound rubber (or final compound rubber), and the final compound rubber is formed...
