Green environment-friendly water-resistant abrasive cloth and preparation method thereof

Abstract

The invention belongs to the technical field of abrasive tools, and particularly relates to green environment-friendly water-resistant abrasive cloth and a preparation method thereof.The green environment-friendly water-resistant abrasive cloth comprises a base cloth layer and grinding particles, fixing grooves used for positioning the grinding particles are evenly distributed in the base cloth layer, a first suede is arranged on the surface of each fixing groove, a second suede is arranged on the surface of the base cloth layer, and the first suede and the second suede are arranged in the fixing grooves. The grinding particles are bonded with the first suede surface and the second suede surface through an adhesive, the second suede surface is coated with a composite adhesive layer for gluing the grinding particles, and the highest points, glued on the base cloth layer through the adhesive and the composite adhesive layer, of the grinding particles are the same in horizontal height. According to the invention, the mechanical property, wear resistance and heat resistance of the matrix can be enhanced, the softening coefficient of the coating is effectively improved, the base cloth layer has excellent water resistance and is green and environment-friendly, particles are uniformly distributed by using the particle counting plate, grinding particles are correspondingly arranged in the fixed mounting grooves of the base cloth layer in a bonding manner, and pressure-maintaining bonding is carried out, so that the wear resistance of the coating is improved. Therefore, the surface of the base cloth layer is uniform in grain distribution and has excellent flatness.

Description

technical field [0001] The invention relates to the technical field of abrasive tools, in particular to a green environmental protection water-resistant abrasive cloth and a preparation method thereof. Background technique [0002] Abrasives include coated abrasives and bonded abrasives. As an important coated abrasive, sandpaper mainly includes substrates, abrasives and binders. The environmentally friendly water-resistant sandpaper is the most traditional kind of sandpaper, which is widely used in the polishing and grinding of paint surfaces and hardware. The base paper is mostly kraft paper, and oily epoxy resin is used as the binder. Kraft paper needs a paper treatment process to apply primer, and paper treatment mostly uses alkyd resin, which needs to be diluted with organic solvent, and the curing temperature is high (170 ° C), which seriously damages the paper base, and the paper base after high temperature treatment becomes very bad. crisp. The oil-based epoxy res...
