Industrial abrasive band based on chopped linen fibers

Abstract

The invention discloses an industrial abrasive band based on chopped linen fibers and aims to solve the technical problems that a base material of the conventional abrasive band does not have a grinding function and is poor in mechanical performance, elasticity modulus is difficultly improved greatly and the like. The industrial abrasive band comprises a base material, wherein the base material is subjected to soaking and scraping treatment or soaked with glue which contains the chopped linen fibers or is added with sand; a layer or a plurality of layers of glue which contains the chopped linen fibers or is added with the sand is formed on one surface, namely the front side or the back side of a treated fabric base through blade coating according to requirements, then a primer containing the glue which contains the chopped linen fibers or is added with the sand is coated, then sand is planted on the primer, and the primer is coated with composite glue, wherein the composite glue can be glue which contains the chopped linen fibers or is added with relative fine grained sand. According to the industrial abrasive band, a messy structure of the chopped linen fibers is adopted, so that the shock resistance of the glue layers is improved; simultaneously, the chopped linen fibers can be synchronously consumed and has certain polishing and grinding performance; and due to certain hardness and brittleness of linen fiber, the industrial abrasive band has grinding capability, the performance is improved, and the using cost is reduced.

Description

technical field

[0001] The present invention relates to an abrasive cloth, in particular to an industrial abrasive belt based on hemp chopped fibers. Background technique

[0002] Coated abrasive industrial abrasive belts are mainly used for cleaning, polishing, and deburring of the surface of metal parts; fine grinding of wooden furniture; leather calendering; polishing of clothing fabrics, glass, ceramics, etc. role. However, the abrasive cloth base materials commonly used in the market are either woven cloth, which makes the whole production cost too high, or is paper, which makes the tear resistance of the product very poor. The base material of any abrasive belt in the prior art only has the function of carrying abrasives, but does not have the function of grinding itself. Contents of the invention

[0003] The purpose of the invention is to solve the technical problems that the existing abrasive belt base material has no grinding function and poor mechanical proper...
