Problems solved by technology

[0003] The skeleton material of the existing polyurethane light conveyor belt generally adopts polyester woven fabric, although it can play the role of conveying and working platform to a certain extent, but the skeleton material of polyester woven fabric will not be used in the process of use, especially in high temperature working environment. In this case, the belt body elongates greatly and the strength is low, resulting in unstable dimensions of the light conveyor belt, which cannot meet the needs of high-quality printed products.

Abstract

The invention relates to a light conveying belt and a preparation method thereof. The conveying belt comprises a Kevlar woven fabric, polyester woven fabrics and a polyurethane covering adhesive layer, wherein the Kevlar woven fabric is used as a middle framework layer; two layers of the polyester woven fabrics are used as a framework material of an upper framework layer and a framework material of a bottom framework layer; and three framework layers are respectively laminated with conductive polyurethane so as to obtain the three-fabric three-adhesive light conveying belt. The preparation method comprises the following steps of: (1) adopting Kevlar as warps of the Kevlar woven fabric and adopting ultra low shrink polyester multifilament yarns as weft yarns of the Kevlar woven fabric, wherein the basic weave is plain weave; (2) gluing the fabric and then sizing the glued fabric; and (3) coating the materials. The conveying belt of the invention has high strength. The integral tensile strength and the peel strength of the conveying belt are greatly improved. The preparation method is simple, has low cost and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of conveyor belts and their preparation, in particular to a light conveyor belt and its preparation method. Background technique [0002] Polyurethane (Polyurethane) light-duty conveyor belts are widely used in the dyeing and finishing industry. As a working platform for dyeing and finishing printing, its extensibility and stability determine the quality of printed products. Therefore, polyurethane light-duty conveyor belts must have relatively high strength, especially It requires high strength at a small elongation, so that it has good dimensional stability to ensure product quality and high production efficiency, and has higher economic value. [0003] The skeleton material of the existing polyurethane light conveyor belt generally adopts polyester woven fabric, although it can play the role of conveying and working platform to a certain extent, but the skeleton material of polyester woven fabric will not be used i...
