Problems solved by technology

[0002] When ordinary canvas is used as the skeleton material of the conveyor belt, when the conveyor belt transports high-temperature materials, although heat-resistant rubber is used as the working surface of the conveyor belt, when the instantaneous high temperature is transmitted to the core skeleton material layer, the canvas will shrink violently, and the conveyor belt will be damaged. Due to the destruction of the inner skeleton material, the belt body will shrink to different degrees and appear "lotus leaf" phenomenon

Abstract

The invention provides a heat-resistant impregnated synthetic fiber canvas and a formula of an impregnating adhesive solution needed by an impregnation process. The warp yarns refer to low shrinkage activated industrial polyester filaments, the weft yarns refer to high-strength polyhexamethylene adipamide fibers, the dry heat shrinkage of the finished canvas can reach a small value at the environment temperature of 175 DEG C, the adhesive force between the canvas layer and rubber at high temperature is enhanced by adopting a special impregnating adhesive solution formula, and separation between the adhesive layer and the canvas layer in the conveyor belt operating process is avoided.

Description

technical field [0001] The invention relates to the field of industrial fabrics, in particular to a heat-resistant glue-dipping synthetic fiber canvas and the formula of the dipping glue required for the dipping process. Background technique [0002] When ordinary canvas is used as the skeleton material of the conveyor belt, when the conveyor belt transports high-temperature materials, although heat-resistant rubber is used as the working surface of the conveyor belt, when the instantaneous high temperature is transmitted to the core skeleton material layer, the canvas will shrink violently, and the conveyor belt will be damaged. Due to the destruction of the inner layer skeleton material, the belt body will shrink due to different degrees, and the "lotus leaf" phenomenon will appear. When we consider that the conveyor belt transports materials with high heat, the role of canvas as a skeleton material will be particularly prominent, and special fiber materials and processes ...
