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 a conveying belt of aramid fiber high in wear resistance and high in bond strength. The conveying belt of the aramid fiber high in wear resistance and high in bond strength comprises an aramid fiber skeleton layer, a buffer layer, upper layer cover gum and lower layer cover gum, wherein the buffer layer is arranged between the upper layer cover gum and the aramid fiber skeleton layer, and the upper layer cover gum and the buffer layer, the aramid fiber skeleton layer and the buffer layer, and the aramid fiber skeleton layer and the lower layer cover gum are respectively bonded together through core gum high in bond strength. Main warp threads of skeleton material of the conveying belt of the aramid fiber high in wear resistance and high in bond strength are made of aramid fiber gum dipping canvas high in strength, and the strength level of the conveying belt which is produced can reach 3150N / mm. The conveying belt of the aramid fiber high in wear resistance and high in bond strength can meet the performance requirements that the belt body of the conveying belt is high in strength, high in wear resistance and high in bond strength, resists impact, resists tearing and the like. The braided structure of the skeleton material of the conveying belt of the aramid fiber high in wear resistance and high in bond strength is a straight warp and straight weft structure, and the conveying belt of the aramid fiber high in wear resistance and high in bond strength is long in use life, low in running energy consumption, reduces the diameter of a transmission drum, and decreases the number of long distance connecting times of ends.

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...
