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] There are also a small number of sandpapers that directly use sponge as the substrate, but the surface of the sponge is not smooth enough, resulting in uneven abrasive surfaces, which cannot be used for grinding and polishing of equipment with high surface precision, and the abrasive and sponge substrates are directly bonded , the workmanship is rough, the workmanship is simple, and the abrasive is easy to fall off and damage during use

Abstract

The invention discloses a piece of sponge abrasive paper comprising a sponge layer, an applying glue layer, a bottom glue layer, an abrasive layer and a composite glue layer. The sponge abrasive paper further comprises a polyurethane film layer; the polyurethane film layer is attached to the sponge layer via at least one applying glue layer; the abrasive layer is attached to the polyurethane film layer via the at least one bottom glue layer and the at least one composite glue layer covering the bottom glue layer. The sponge abrasive paper is two-layered base material with an upper sponge base material layer and a lower thin film base material layer. Compared with products of the same kind on the market, the sponge abrasive paper is characterized by high elasticity, super softness, stability, durableness and free grinding scratches.

Description

technical field [0001] The invention belongs to the technical field of coated abrasives, and relates to sandpaper, in particular to sponge sandpaper and a manufacturing method thereof. Background technique [0002] There are many types of polishing abrasives currently on the market, among which sheet-shaped sandpaper is mostly composed of base material, 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] There are also a small number of sandpapers that directly use sponge as the substrate, but the surface of the sponge is not smoot...
