Production process of maintenance-free triangular belt with transverse fiber bundles

Abstract

The invention discloses a production process of a maintenance-free triangular belt with transverse fiber bundles. The triangular belt comprises a core layer and an adhesive tape layer on the back of the belt body, wherein the core layer sequentially comprises a bottom adhesive layer, a cord thread layer, a viscose layer, a polyester hard line rope and a buffer adhesive layer from the bottom to top; the bottom adhesive layer is burdened according to technical requirements, and production is performed according to the production process including mixing, rolling, reversed splicing, molding, vulcanizing, cutting, milling and the like. According to the process disclosed by the invention, the service life of the product is prolonged, early damage on the surface of the triangular belt is effectively avoided, the wear resistance is improved, the grip between the triangular belt and a grooved pulley is increased, noise during transmission is reduced, and the maintenance-free technical requirement is met.

Description

technical field [0001] The invention belongs to the technical field of transmission belt preparation, relates to a V-belt produced with rubber as a raw material, in particular to a production process of a maintenance-free V-belt with transverse fiber bundles. Background technique [0002] V-belt is a kind of conveyor belt widely used in various machinery. It is mainly composed of industrial canvas, polyester soft cord and primer layer. The primer layer is mainly composed of natural rubber, styrene-butadiene rubber, reclaimed rubber and compounding agent. (zinc oxide, stearic acid, anti-aging agent, carbon black, softener, etc.). However, the existing V-belts generally have the problems that the product is easy to sag, resulting in large deformation, poor fatigue resistance and flexibility, prone to failure, and short service life. However, if the polyester hard cord is used in the V-belt, the V-belt is prone to sag, which causes the V-belt to deform laterally, causing the f...

AI Technical Summary

Problems solved by technology

However, if it is directly applied to the V-belt, there are still many defects. The composition of the fiber film is unreasonable. If it is directly applied to the V-belt, since the strong layer is made of polyester hard cord, the material is relatively hard, and the product will be damaged during use. Depression occurs. In addition, although the fiber film is added with short polyester fibers, because the fiber film is formed by calendering during processing, the short polyester fibers in the fiber film are arranged in a longitudinal direction and can be used directly. The arrangement direction of the short polyester fiber will be consistent with the direction of the polyester hard cord wound longitudinally in the V-belt, so that it will not be able to support the product, and it will also make the product prone to dents, serious lateral deformation, and reduce the service life of the product.
