Problems solved by technology

Especially in mines and open-pit coal mines in Northeast and Northwest my country, the low temperature in the severe cold period often reaches below -50°C, and the steel cord conveyor belts of the prior art will become hard and brittle when used in such ambient temperatures, and their mechanical properties will seriously decline. , the service life is short under the condition of impact load, and even the performance is lost
In the prior art, there are many studies on improving the mechanical properties of steel cord conveyor belts under normal and high temperature conditions, but there are few studies on how to improve the mechanical properties and service life of steel cord conveyor belts under low temperature and impact load conditions.

Abstract

The invention discloses a wear-resistant cold-resistant impact-resistant steel wire rope core conveying belt and a manufacturing method thereof. According to the invention, natural rubber / butadiene styrene rubber / butadiene rubber is selected as a host material, N234 carbon black is selected as a reinforcing agent, a CMoSSi wear-resisting agent is added, and a wear-resistant cold-resistant impact-resistant rubber composite material is prepared through formula and process optimization and serves as a covering layer of the steel wire rope core conveying belt; a conveying rubber belt has excellentwear resistance and impact resistance, still has good mechanical properties and long service life under the conditions of low temperature and impact load, and meets the use requirements of the steelwire rope core conveying belt in a low-temperature environment; and the manufacturing method is simple in process and can easily manufacture the steel wire rope core conveying belt.

Description

technical field [0001] The invention relates to the technical field of mine conveyor belts, in particular to a wear-resistant, cold-resistant and impact-resistant steel cord conveyor belt and a manufacturing method thereof. Background technique [0002] Steel cord conveyor belts used in mines, ports, open-pit coal mines and other workplaces are required to have high wear resistance, impact resistance, and low temperature resistance due to the harsh working environment and high impact load. Especially in mines and open-pit coal mines in Northeast and Northwest my country, the low temperature in the severe cold period often reaches below -50°C, and the steel cord conveyor belts of the prior art will become hard and brittle when used in such ambient temperatures, and their mechanical properties will seriously decline. , the service life is short under the condition of impact load, and even the performance is lost. In the prior art, there are many studies on improving the mechan...
