Abstract

The invention discloses a resin-based high-viscosity heat-resistant grinding wheel material, which is prepared from the following raw materials: modified phenolic resin, bisphenol-A epoxy resin, silicon resin, polyimide resin, bismaleimide, zinc stearate, graphite, precipitated calcium carbonate, titanium dioxide, diamond, cerium oxide, talcum powder, silicon carbide, silica, silicon nitride, aluminum oxide, boric oxide, boron nitride, azodicarbonamide, imidazole, phenyltrimethoxysilane, 4,4-dioxylbisbenzensulfonyl hydrazide, a silane coupling agent KH-570 and a wear-resistant additive. The prepared resin-based high-viscosity heat-resistant grinding wheel material has excellent wear-resisting property, good adhesion and high hardness; the heat resistance and the hardness of a resin grinding wheel are improved; cracks formed by rigid grinding is reduced; heat dissipation is fast; dispersion of a lot of heat released from the grinding wheel in the cutting process is facilitated; and the resin-based high-viscosity heat-resistant grinding wheel material plays a role in reducing the cutting temperature.

Description

technical field [0001] The invention relates to the technical field of grinding wheel materials, in particular to a resin-based high-viscosity heat-resistant grinding wheel material. Background technique [0002] Resin diamond grinding wheel occupies a relatively large share in the superhard material abrasive tool market because of its sharpness, wear resistance, and good processing accuracy. Subject to certain limitations, it is urgent to develop a resin-based high-viscosity heat-resistant grinding wheel material to solve the problems in the prior art. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a resin-based high-viscosity heat-resistant grinding wheel material, which has excellent wear resistance, good adhesion, and high hardness, and improves the heat resistance and hardness of the resin grinding wheel. Reduce the cracks formed by rigid grinding, and quickly dissipate...
