A kind of wear-resistant sandpaper and its production process

Abstract

The invention discloses wear-resistant abrasive paper and a production process thereof. According to the wear-resistant abrasive paper and the production process thereof, the problem in the prior artthat existing abrasive paper is prone to blocking by abrasive dust on the abrasive paper when the abrasive paper is used is solved. The wear-resistant abrasive paper is characterized in that wear-resistant abrasive paper sequentially comprises a substrate layer, a bonding layer and an abrasive material layer, wherein the abrasive material layer comprises first abrasive particles and second abrasive particles; the bottom ends of the first abrasive particles are built into the bonding layer; the mesh number of each second abrasive particle is less than the mesh number of each first abrasive particle; the second abrasive particles are arranged on gaps, between the first abrasive particles, on the bonding layer; and the bonding layer is coated with an anti-blocking layer. According to the scheme, two abrasive particles with different sizes are adopted in the abrasive material layer, and the smaller abrasive particles are distributed between the large grinding particles, so that the gaps between the particles of the abrasive material layer are more compact so as to enable the abrasive dust to be difficult to remain in the gaps between the abrasive materials when the abrasive paper is used; and meanwhile, the anti-blocking layer coated on the abrasive material layer is able to prevent the abrasive dust from adhering to the abrasive surface, so that the abrasive paper is fully used, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of sandpaper production, in particular to a wear-resistant sandpaper and a production process 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 workpiece to be ground 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 will be bonded and mixed together, 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 and reducing the service life of the sandpaper. Therefore, the production of high-quality sandpaper has become an urgent direction for my country's sandpaper industry
