Abrasion-resistant abrasive paper provided with porous structure

Abstract

An abrasion-resistant abrasive paper provided with a porous structure comprises a paper substrate layer (1) and a bottom adhesive layer (4), wherein a mesh fabric layer (2) is stuck to the bottom surface of the paper substrate layer (1); a large particle abrasion-resistant layer (5) is arranged on the upper surface of the bottom adhesive layer (4); the outer surface of the large particle abrasion-resistant material is coated with compound glue (6); a small particle super coating (7) is laid on the compound glue (6); and micropores (3) penetrating through the paper substrate layer (1) and the bottom adhesive layer (4) are pressed in the surface of the paper substrate layer (1). According to the abrasion-resistant abrasive paper provided with the porous structure, the small particle super coating is stuck to and fixed with the outer surface of the large particle abrasion-resistant material, therefore, the abrasion resisting property is improved, and the service life of the large particle abrasion-resistant layer is prolonged; and further, the micropores penetrating through the paper substrate layer and the bottom adhesive layer are pressed in the surface of the paper substrate layer, accordingly, blockage caused by dust and small fragmentary particles on the surface of the abrasive paper can be relieved to a certain extent, the grinding effect is improved, and the service life of the abrasive paper is prolonged greatly.

Description

technical field [0001] The invention relates to a wear-resistant sandpaper, in particular to a wear-resistant sandpaper with a porous structure, which belongs to the technical field of grinding tools. Background technique [0002] At present, there is a great demand for sandpaper in the fields of building decoration, furniture production, machinery manufacturing, and maintenance and anticorrosion. The existing sandpaper is widely used for its convenient production, low cost, and good versatility. However, the service life of the existing sandpaper is generally short, and the grinding layer on the surface has lost its grinding ability before it is completely worn off. The fundamental reason is that the sandpaper itself has poor wear resistance, and the more important reason is During the grinding process, the wear-resistant particles on the sandpaper will fall off or produce wear debris, and the dust and particles generated by the grinding parts will easily adhere to the sur...
