Abstract

The invention relates to a method for preparing a non-woven fabric polishing abrasive tool with high abrasion resistance. The method comprises the following steps of: taking 20 to 40 mass parts of epoxy resin, adding 4 to 25 mass parts of curing agent, 20 to 45 mass parts of abrasive, 8 to 15 mass parts of diluent, 2 to 8 mass parts of toughening agent, 1 to 3 mass parts of silane coupling agent and 3 to 8 mass parts of auxiliary materials into the epoxy resin, mixing the materials uniformly, then spraying the mixture onto a non-woven fabric, curing the mixture at a high temperature, and then performing punch forming, wherein the toughening agent comprises reactive epoxy toughening agent, terminal carboxyl liquid nitrile rubber and / or terminal carboxyl polybutadiene liquid rubber; the silane coupling agent comprises gamma-aminopropyltriethoxysilane, gamma-glycidyl ether oxypropyl trimethoxy silane and / or gamma-(methacryloyloxy) propyltrimethoxysilane; and the other auxiliary materials comprise 2,4,6-tri(dimethylaminomethyl) phenol DMP-30 accelerator, wax powder, graphite, pigment, magnesium stearate and / or zinc stearate. The non-woven fabric polishing abrasive tool is mainly used for polishing treatment of metal surfaces.

Description

Technical field [0001] The invention relates to a non-woven polishing abrasive tool with high wear resistance, which can be used as a polishing treatment for metal surfaces. Background technique [0002] Due to the low hardening temperature of resin bond abrasive tools, it can be hardened at room temperature with a small shrinkage rate, and can be made into abrasive tools with various complex shapes and special requirements. Organic abrasive tools have a wide range of applications, have certain elasticity and high bonding strength, and have good polishing performance. It has been applied in the grinding process of coarse, fine, fine and polishing. [0003] Chinese invention patent application CN101200053A discloses a method for manufacturing epoxy resin combined with composite abrasive abrasive tools. The components and weight ratios included are: 15-78% epoxy resin, 2-44% abrasive, and curing agent 4- 18%, and other auxiliary materials include alumina, barium chloride, quartz sa...
