Problems solved by technology

Among them, the base material is mostly made of paper material or single-layer cloth or film. The softness of paper material is not enough when used, the paper base is easy to be brittle and damaged, it is easy to rot when exposed to water, and it is easy to scratch and polish equipment when used; Layered cloth or film as the base material is easy to wear, especially for equipment with a rough surface, the loss is greater, and it is not durable
[0003] With the continuous improvement of production level, the demand for sandpaper and abrasive cloth is also more extensive. People need a higher level of abrasive cloth to meet the needs of actual production, especially suitable for grinding metal, wood, and electronic industries; The anti-blocking effect is poor and the grinding life is short; therefore, an abrasive cloth with superior anti-blocking effect, long service life and high strength is required to meet the requirements

Abstract

The invention discloses a method for preparing waterproof thin film abrasive paper. The method includes the following steps of firstly, selecting a PET film or a PVC film as base cloth; secondly, coating the base cloth with a layer of primer through a roller, wherein the primer comprises adhesives, fillers, coupling agents and diluents, and the mass ratio of the adhesives to the fillers to the coupling agents to the diluents is 100:10-40:2:10-40; thirdly, enabling abrasive materials to adhere to the primer through a gravity abrasive plantation method, and then conducting drying, wherein the drying temperature ranges from 80 DEG C to 100 DEG C; fourthly, coating the layer of abrasive materials with a layer of laminating adhesive through a roller coating method, and then placing the product into a curing oven at the temperature of 100 DEG C to 120 DEG C to be cured for 24 hours to 48 hours, wherein the laminating adhesive comprises adhesives, fillers, pigments and diluents, and the mass ratio of the adhesives to the fillers to the pigments to the diluents is 100:10-40:5:10-40. Adhesive paper prepared through the method has an excellent anti-blocking effect, and is long in service life and high in strength.

Description

technical field [0001] The invention relates to a preparation method of abrasive cloth, in particular to a preparation method of water-resistant film sandpaper. Background technique [0002] There are many types of polishing abrasives currently on the market, most of which are sheet-shaped sandpapers, which are mainly composed of substrates, viscose and abrasives. Among them, the base material is mostly made of paper material or single-layer cloth or film. The softness of paper material is not enough when used, the paper base is easy to be brittle and damaged, it is easy to rot when exposed to water, and it is easy to scratch and polish equipment when used; If a layer of cloth or film is used as the base material, it is easy to wear, especially for equipment with a rough surface, the loss is greater, and it is very undurable. [0003] With the continuous improvement of production level, the demand for sandpaper and abrasive cloth is also more extensive. People need a higher...
