Abstract

The invention relates to conveying belt covering rubber and a preparation method thereof, in particular to anti-tensile and wear-proof flame-retardant conveying belt covering rubber and a preparation method thereof. The covering rubber comprises the following components in parts by weight: 60-90 parts of butadiene styrene rubber, 5-35 parts of natural rubber, 5-15 parts of butadiene rubber, 3.5-7.5 parts of activator, 2.5-6.5 parts of antiager, 50-70 parts of carbon black, 3.5-5.5 parts of dispersing agent, 0.5-3.5 parts of sulfur, 0.5-3.5 parts of vulcanization accelerator, 9.0-15.0 parts of C5 resin and 20-45 parts of fire retardant. By considering an anti-tensile property, a wear-proof property, processability and other aspects comprehensively, a selected formula system of the anti-tensile and wear-proof flame-retardant conveying belt covering rubber can achieve an excellent effect; the tensile strength is improved by 17.3% in comparison with the existing product; the wear-proof property is improved by 38%; requirements of material conveying on the temperature are met; the service life of a conveying belt is greatly prolonged; and very good economic benefits are realized.

Description

technical field [0001] The invention relates to a conveyor belt covering glue and a preparation method thereof, in particular to a stretch-resistant and wear-resistant flame-retardant conveyor belt covering glue and a preparation method thereof. Background technique [0002] With the continuous improvement of productivity, industrial and mining enterprises such as coal mines, ports, and steel mills have an increasing demand for conveyor belts. At the same time, due to the continuous expansion of production scale and continuous improvement of production capacity, the quality of conveyor belts is also increasingly demanding. Especially for the wear resistance of the covering rubber on the working surface of the conveyor belt. [0003] The materials conveyed in the steel and cement industries generally have the characteristics of high temperature, and at the same time, considering the service life of the conveyor belt, the conveyor belt is usually required to have better wear r...
