Problems solved by technology

When the layered belt passes through the driving roller, due to the different yield radii, the inner layer is compressed and the outer layer is stretched, and the force of each layer of skeleton material is different, so the more layers, the worse the flex life. The more prone to delamination problems, the shorter the service life

Abstract

The invention relates to an aramid fiber conveyor belt with high wear resistance and high adhesion, which comprises an aramid fiber skeleton layer, a buffer layer, an upper layer of covering glue and a lower layer of covering glue, the buffer layer is between the upper layer of covering glue and the aramid fiber skeleton layer, the upper layer of covering glue The buffer layer, the aramid fiber skeleton layer and the buffer layer, the aramid fiber skeleton layer and the lower cover rubber are bonded together by high-adhesion core glue. The main warp of the skeleton material in the present invention adopts high-strength aramid-impregnated canvas, and the strength level of the produced conveyor belt can reach 3150N / mm. The conveyor belt meets the performance requirements of high belt body strength, high wear resistance, high adhesive strength, impact resistance, and tear resistance. The weaving structure of the framework material of the present invention is a straight warp and straight weft structure, which has long service life, low energy consumption in operation, smaller diameter of the transmission drum, and fewer long-distance splicing times.

Description

technical field [0001] The invention relates to an aramid conveyor belt with high wear resistance and high bonding strength, which belongs to the field of rubber conveyor belt products. Background technique [0002] With the development of modern industrial conveying materials, belt conveying has become one of the most economical and effective transportation methods in solving environmental, manpower, energy, transportation space and other issues. [0003] The conveyor belt for the ground is mainly a layered belt, which is made of EP canvas or NN glued and laminated in multiple layers, and the upper and lower sides are laminated with covering glue and then vulcanized. When the layered belt passes through the driving roller, due to the different yield radii, the inner layer is compressed and the outer layer is stretched, and the force of each layer of skeleton material is different, so the more layers, the worse the flex life. The more prone to delamination problems, the sho...
