Abstract

The invention relates to a heat-resistant wear-resistant belt conveyor cover rubber and a preparation method thereof. The product has favorable wear resistance. The preparation method comprises the following steps: carrying out plastification or co-plastification on styrene-butadiene rubber and cis-1,4-polybutadiene rubber on an open mill, and banburying the plastified rubber in a Banbury mixer; opening a ram piston, adding reinforcing filler, vulcanization activator, coupling agent, plasticizer, anti-aging agent and vulcanization retarder, carrying out turn milling, discharging, and cooling with a fan at normal temperature to obtain a first-section compounded rubber; and carrying out second-section compounding to obtain the product heat-resistant wear-resistant belt conveyor cover rubber, wherein the second-section compounding comprises the following steps: compounding the first-section compounded rubber, vulcanizing agent and vulcanization accelerator in a Banbury mixer, carrying out turning milling, discharging, and cooling with a fan at normal temperature. The heat-resistant wear-resistant belt conveyor cover rubber satisfies the requirement of material conveying in a steel factory for temperature, and greatly prolongs the service life of the belt conveyor, thereby implementing favorable economic benefit.

Description

technical field [0001] The invention relates to a heat-resistant and wear-resistant conveyor belt covering rubber and a preparation method thereof. The prepared product has good wear resistance and is suitable for making a canvas core heat-resistant conveyor belt conforming to the GB / T 20021-2005 standard. Background technique [0002] In recent years, the rapid development of China's economy has promoted the rapid growth of steel, cement and other industries, the production scale has been continuously expanded, and the production capacity has been continuously improved. high demands. [0003] The materials conveyed in the steel and cement industries generally have the characteristics of high temperature. At the same time, due to the consideration of the service life of the conveyor belt, the conveyor belt is usually required to have better wear resistance. However, the currently used domestic T2 grade heat-resistant conveyor belts can only meet the temperature requirements...
