Problems solved by technology

At present, the main defects of the high wear-resistant conveyor belt produced at home and abroad in the process of use: when conveying large and sharp materials, the covering rubber on the working surface of the belt is worn out early, cut into small rubber particles by the material and scrapped, and the service life is short
[0004] Chinese patent CN201485013U discloses a super wear-resistant conveyor belt, which includes an upper wear-resistant layer and a lower wear-resistant layer, both of which are made of polyurethane and smoked sheet glue. Rubber-dipped aramid cord fabric layer and metal spiral core layer, the conveyor belt with this structure has good impact resistance and wear resistance, but because the single layer covers the wear-resistant layer, the overall toughness and tear resistance are not strong, and the service life is still not long
Chinese patent CN203111941U discloses a high-temperature-resistant and wear-resistant conveyor belt, which includes an upper cover rubber layer, a belt core and a lower cover rubber layer, wherein the belt core is nylon mesh or steel cord mesh, which can reduce the impact of materials on the cover rubber layer. Impact wear strength, but the cushioning force is not enough, which has little effect on the life of the conveyor belt

Abstract

The invention discloses a conveyer belt with high abrasion resistance. The conveyer belt comprises an upper covering adhesive layer, a belt core and a lower covering adhesive layer, wherein the upper covering adhesive layer is composed of a cutting-resistant adhesive layer and an abrasion-resistant adhesive layer; and an anti-tear skeleton layer is arranged between the abrasion-resistant adhesive layer and the belt core. The conveyer belt has good abrasion resistance, impact resistance and elasticity, and is long in service life and suitable for being used in mines and other occasions with relatively high abrasion.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to a high wear-resistant conveyor belt. Background technique [0002] Belt conveyor is one of the most common and economical material conveying methods. In particular, the super wear-resistant conveyor belt has unique advantages that other products cannot replace due to its strong wear resistance, impact resistance and high elasticity. Therefore, it is widely used in metallurgy, mining, docks and other industries, showing super wear Abrasive conveyor belts have broad market prospects in material transportation and have significant social and economic benefits. [0003] At present, many conveyor belt manufacturers at home and abroad are developing and producing super wear-resistant conveyor belts, but there is no major progress. At present, the main defects of the high wear-resistant conveyor belt produced at home and abroad in the process of use: when conveying large and sharp materials, the cov...
