Antistatic TPU belt

Abstract

The invention belongs to the technical field of conveying belts, and particularly relates to an antistatic TPU belt. The antistatic TPU belt comprises a fabric inner core and a covering rubber layer.;the fabric inner core is composed of warp yarns and weft yarns, and the warp yarns and the weft yarns are woven up and down according to a plain weaving method; the warp yarns are composed of polyester or cotton fiber or aramid fiber and polyamide fiber; and the weft yarns are composed of nylon-based conductive fiber, hollow glass fiber and polypropylene fiber. According to the invention, the fabric inner core is improved, the wear resistance and the strength of the conveying belt are guaranteed by the warp yarns, antistatic property of the conveying belt and high temperature resistance of the conveying belt are improved by the weft yarns; antistatic principles of the fabric inner core are that corona discharge is caused by an electric field to neutralize static electricity, so that an antistatic effect is achieved, and antistatic effect is good. By improving the covering rubber layer, the adding amount of wear-resistant conductive carbon black is reduced, and meanwhile, a certain amount of PVC resin is added, so that the tensile strength and the impact strength of the covering rubber layer are ensured.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to an antistatic TPU belt. Background technique [0002] TPU (thermoplastic polyurethane elastomer) is an emerging polymer material with high elasticity, high Young's modulus, good flexibility, wear resistance, weather resistance, oil resistance, solvent resistance, environmental protection and other excellent properties. Therefore, it is widely used in ships, vehicles, aviation, light industry, textile and other departments. [0003] As a light conveyor belt, TPU conveyor belt has been widely used in many industries due to its advantages of light weight, long life, good flame retardancy, and less friction. [0004] During the use of the TPU conveyor belt, it needs constant friction with the machinery, and there is also friction with the transported objects, so a large amount of charge accumulation is generated, which requires that the front and back sides of the conveyor be...

AI Technical Summary

Problems solved by technology

[0005] The current treatment method is mainly to improve the antistatic ability of the TPU conveyor belt by adding a certain amount of conductive carbon black to the TPU resin during the preparation of the TPU coating, which not only accelerates the leakage of static electricity, but also avoids a large amount of accumulation of static electricity. Too much conductive carbon black will affect the tensile strength and impact strength of the TPU conveyor belt, thereby reducing the performance of the TPU conveyor belt. At the same time, the addition of too much conductive carbon black will cause difficulties in the lamination of TPU glue, resulting in difficulty in the production process Big
