Industrial abrasive belt based on substrate formed by compounding knitted fabric or woven fabric with plastic film

Abstract

The invention relates to an industrial abrasive belt based on a substrate formed by compounding a knitted fabric or woven fabric with a plastic film, and aims to solve the problem that the conventional product is low in sand-planting surface smoothness and mechanical property and overhigh in manufacturing cost. The abrasive belt comprises the knitted fabric or woven fabric and the plastic film bonded with the knitted fabric or woven fabric, wherein one of surfaces of the knitted fabric or woven fabric and the plastic film, which are far away from each other, is coated with primer; the surface coated with the primer is subjected to electrostatic sand-planting to form an abrasive layer; the knitted fabric or woven fabric is impregnated into or coated with glue; and the glue and the primer are one or more of urea formaldehyde and modified resin thereof, phenolic aldehyde and modified resin thereof, epoxy and modified resin thereof, and acrylic acid and modified resin thereof. The industrial abrasive belt formed by compounding the fabric with the plastic film has required impact resistance and mechanical property by using the flexibility and mechanical property of the fabric and the smoothness of the plastic film, and the manufacturing cost and using cost of the product are effectively reduced.

Description

technical field [0001] The invention relates to an industrial abrasive belt, in particular to an industrial abrasive belt made of a composite base material based on knitted or woven fabric and a plastic film. 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. [0003] In the prior art, due to the properties of various materials and the composite glue required for mutual bonding cannot meet the requirements, the industrial abrasive belts are made by using knitted cloth or woven cloth as the base material alone or using plastic film as the base material. Knitted or woven fabrics are stretched, scraped or dipped, front scraped, back scraped, primed, electrostatically sanded, and glued to make industrial abrasive belts. The main products are abrasive cloth rin...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of insufficient flatness, poor mechanical properties and high manufacturing cost of existing products, and to provide an industrial abrasive belt based on the composite substrate of knitted or woven cloth and plastic film. The industrial abrasive belt utilizes the flexibility and mechanical properties of knitted or woven fabrics, and the flatness of the plastic film itself. After the two are combined, they can not only achieve the required impact resistance, but also achieve the required mechanical properties, and are effective Reduce the cost of production and use of products
