Problems solved by technology

[0009] Generally speaking, the above surface modification methods are only aimed at the adhesive performance of ultra-high molecular weight polyethylene and resin, but there is no report on improving the adhesive performance with rubber, and the above modification methods are cumbersome and costly. Toxic substances are produced in it, which not only pollutes the environment, but also easily causes strength damage to UHMWPE itself, which is not suitable for industrial production

Abstract

The invention relates to a light and high-strength rubber conveyor belt and a preparation method tof the conveyor belt. The conveyor belt comprises a framework layer, an adhesive glue, and upper and lower cover rubber laminated structures; the framework layer adopts mixed woven canvas of ultra-high molecular weight polyethylene fibers and polyester fibers which are treated by plasma, simultaneously adopts low-temperature vulcanization technology to be subjected to covulcanization with the adhesive glue and a cover rubber at a low temperature, and solves the problem of the bonding of ultra-high molecular weight polyethylene fiber cloth and rubber. Compared with the conventional high-strength conveyor belt of wire rope core, the light and high-strength rubber conveyor belt in the invention not only has high strength, and good corrosion resistance, wear resistance, shock resistance and fatigue resistance, but also greatly reduces the weight and thickness, thereby reducing the conveying power energy consumption, which is expected to have long service life and good energy saving and environment friendly performances. Therefore the light and high-strength rubber conveyor belt disclosed in the invention is particularly suitable for the long-distance material conveying in the industries of coal mine, metallurgy, mine and the like.

Description

technical field [0001] The invention relates to a light-weight high-strength rubber conveyor belt and a preparation method thereof, which is especially suitable for long-distance material transportation in industries such as coal mines, metallurgy, and mines. Background technique [0002] Rubber conveyor belts play an extremely important role in various industries, especially in heavy-duty transportation. With the development of rubber conveyor belts towards long distance, high speed, large width and large conveying capacity, the power consumption of conveyor belts is facing a huge challenge. Steel cord rubber conveyor belt is currently widely used in metallurgy, mining, power plants, ports and other industries. It is the most commonly used conveyor belt for large-capacity and long-distance material transportation. In terms of service life, the service life of domestic steel cord conveyor belts is generally 8 to 10 years, while that of steel cord conveyor belts in developed...
