Water-based environmental-friendly sandpaper and production method thereof

Abstract

The invention provides water-based environmental-friendly sandpaper. The water-based environmental-friendly sandpaper comprises a base paper layer (1), a waterproof treatment layer (2), a bottom gluelayer (3), an abrasive layer (4), a compound glue layer (5) and an anti-blocking treatment layer (6) which are sequentially arranged from bottom to top. The waterproof treatment layer in the sandpaperimproves the waterproof capability, tensile strength, softness, folding endurance and smoothness of the base paper layer and effectively prevents base glue and compound glue from penetrating to the back of the base paper layer. The anti-blocking treatment layer in the sandpaper can make abrasive dust fall off and be not adhered to the sandpaper, so that the blocking phenomenon generated during the grinding of the sandpaper is reduced effectively, the service life of the sandpaper is greatly prolonged, and the grinding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sandpaper production, in particular to a water-based environment-friendly green sandpaper and a production method thereof. Background technique [0002] The main raw materials of sandpaper are base material, abrasive and adhesive. It is a grinding and polishing tool made by adhering abrasives to a substrate with an adhesive, and is sometimes used to increase friction. Sandpaper is mainly used in the fields of high-grade furniture, woodwork painting and polishing, fine grinding of handicrafts, metal polishing and so on. In order to improve the strength of sandpaper, the base material not only requires toughness, but also has good wear resistance and water resistance. [0003] And existing sandpaper, general waterproof ability is relatively poor, and sandpaper can produce high temperature when grinding simultaneously, and at this moment local abrasive material on sandpaper and the grinding debris on the w...

Problems solved by technology

[0003] And existing sandpaper, general waterproof ability is relatively poor, and sandpaper can produce high temperature when grinding simultaneously, and at this moment local abrasive material on sandpaper and the grinding debris on the workpiece to be ground can be bonded and mixed together, be blocked on the sand surface, As a result, the abrasive on the sandpaper cannot fully play its role, causing the service life of the sandpaper to end early, reducing the service life of the sandpaper, and the traditional sandpaper uses alkyd resin and epoxy resin as the adhesive for the sandpaper. A large number of harmful small molecular substances will be released during storage, which not only pollutes the environment but also damages human health. Because both are oily glues, they need to be diluted with organic solvents when used, and the workshop smells very strong during production. Current Environmental Policy
