Abstract

The invention relates to the technical field of metal cutting tool preparation, in particular to a preparation method of a high-strength high-heat-resistant resin grinding wheel. The method comprisesthe steps that silicon carbide is put into an arc chamber to be subjected to discharging heating so as to generate a discharging product, then graphite powder serves as a raw material to obtain an oxidation product, then the oxidation product is mixed with tetrabutyl titanate to obtain a dried product, and finally, epoxy resin, the discharging product, the dried product and the like are mixed andmelted uniformly, and then poured into a mold to be solidified to obtain the high-strength high-heat-resistant resin grinding wheel. The heat generated by the silicon carbide during energization is huge, so that iron is melted and evaporated into gas, thereby playing a very good role in catalytic action for the generation of a silicon carbide nano material; the oxidation of potassium permanganateand hydrogen peroxide causes that the surface of graphene introduces oxygen-containing groups and forms carbon vacancies, so that the graphene and titanium dioxide molecules are attached and bonded more easily, thereby improving the hardness and heat resistance of the resin grinding wheel, and the application prospects are broad.

Description

technical field [0001] The invention relates to the technical field of preparation of metal cutting tool products, in particular to a preparation method of a high-strength and high-heat-resistant resin grinding wheel. Background technique [0002] The abrasives industry is an important and indispensable industry in the machine tool industry. Its products are widely used in various industries in the processing and manufacturing industry, and the application fields involved have been continuously expanded in recent years. [0003] Grinding wheel is the most important type of abrasive tool in grinding process. It is a porous body made by adding binder to abrasive, compacting, drying and roasting. The grinding wheel rotates at high speed during use, so there are high requirements for the strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel. The abrasives used in the preparation of grinding wheels mainly include different types of corundum,...
