Abstract

The invention relates to a high-porosity resin grinding wheel and a preparation method thereof. The high-porosity resin grinding wheel is mainly prepared from the following raw materials in parts by weight: 20-33 parts of water-soluble phenolic resin liquid, 6-8 parts of a curing agent, 50-63 parts of an abrasive, 1-1.3 parts of a surfactant, 5 parts of expanded microspheres and 2.7-5 parts of water. The porosity of the high-porosity resin grinding tool provided by the invention is as high as 62-70%, and pores are more uniformly distributed; and the pore size is about 100 [mu]m, and a developed microporous system is formed, so that the resin grinding tool has the advantages of greatly enhanced heat-conducting property, favorable self-sharpening property, no need of finishing and excellentchip-containing property, enhances the grinding property of the substrate material, lowers the damage rate of the substrate surface, enhances the processing efficiency and lowers the processing cost.

Description

technical field [0001] The invention belongs to the field of abrasive abrasives, and in particular relates to a high-porosity resin grinding wheel and a preparation method thereof. Background technique [0002] Resin grinding wheels are widely used in industrial production such as machining because of their high strength, high elasticity and impact resistance. However, the disadvantages of poor heat resistance and small porosity of the resin grinding wheel in the prior art limit the application of the resin grinding wheel in industrial production. [0003] For resin grinding wheels, the size of the porosity and the distribution of pores play a vital role in the organizational structure of the resin grinding wheel, that is, the prepared resin grinding wheel must have ideal porosity and ideal distribution of pores to ensure that the resin grinding wheel is It has high cutting efficiency and low grinding ratio when grinding. [0004] In general, the denser the internal struct...
