Problems solved by technology

The current conveyor belt skeleton materials are mainly polyester fiber, cotton fiber, etc., among which polyester fiber is the most widely used due to its high strength, but it is prone to high shrinkage under high temperature conditions, which affects the quality and service life of the conveyor belt; cotton Although the fiber has a small shrinkage rate at high temperature, its use is limited due to its low strength

Abstract

The invention discloses a framework material for conveyor belts and a method for preparing the framework material. The framework material is prepared from canvas materials with impregnation liquid. The impregnation liquid is prepared from acetic acrylic latex, carboxylic butadiene-styrene latex, caffeic acid, hydroxypyridine, N, N-dimethyl diphenyl urylene, ethylene diglycidyl ether, urea, ethyl acetate and distilled water; wire twisting and weaving working procedures are carried out on para-aramid fibers, nylon 66 fibers, polyester PEN (polyethylene naphthalate) fibers and cotton fibers, andthen the para-aramid fibers, the nylon 66 fibers, the polyester PEN fibers and the cotton fibers are processed to obtain the canvas materials. The framework material for the conveyor belts and the method have the advantages that the framework material is low in high-temperature shrinkage, high in breaking strength and excellent in comprehensive performance, the service lives of the conveyor beltscan be obviously prolonged, and accordingly the framework material and the method have broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of conveyor belts, and in particular relates to a conveyor belt framework material and a preparation method thereof. Background technique [0002] Conveyor belt is an important part of material conveyor, widely used in various industries such as building materials, chemical industry, electromechanical, light industry, textile, agriculture, metallurgy, coal and so on. The conveyor belt is composed of skeleton material and covering rubber. During the use of the conveyor belt, it needs to draw a large force and be subjected to interactive stress. More than 95% of the force is borne by the skeleton material. Therefore, the skeleton material is an important part of the conveyor belt. The skeleton material is in the It greatly affects the conveying effect, usage occasion and service life of the conveyor belt. [0003] The skeleton material should meet the following basic performance requirements: good heat resist...
