Abstract

The invention discloses a resin-based high-strength wear-resistant grinding wheel material. The resin-based high-strength wear-resistant grinding wheel material is prepared from modified phenolic resin, epoxy resin, powder butadiene-acrylonitrile rubber, polyurethane elastomer, polyvinyl butyral, iron disulfide, copper powder, zinc oxide, graphite, hollow ceramic balls, corundum, carborundum, talcum powder, silicon carbide, aluminum oxide, boron oxide, boron nitride, chromic oxide, nanosilicon dioxide, a silane coupling agent, namely KH-550 and wear-resistant auxiliary agents. The invention further provides a preparation method of the resin-based high-strength wear-resistant grinding wheel material. The resin-based high-strength wear-resistant grinding wheel material is excellent in wear resistance, good in bonding performance and high in hardness; heat resistance and hardness of a resin grinding wheel are improved; cracks formed due to rigid grinding are reduced; heat is dissipated fast; a great amount of heat released in the cutting process of the grinding wheel can be dissipated fast and conveniently; and the effect that the cutting temperature is lowered is achieved.

Description

technical field [0001] The invention relates to the technical field of grinding wheel materials, in particular to a resin-based high-strength wear-resistant grinding wheel material and a preparation method thereof. Background technique [0002] Grinding wheels used for polishing can be generally divided into three categories: vitrified bonded grinding wheels, rubber bonded grinding wheels and resin bonded grinding wheels according to the type of bond used. Vitrified bonded grinding wheels are the earliest developed and used in the largest amount. Rubber bonded grinding wheels Due to the complex operation process, its market is small. The resin bonded grinding wheel is made of resin as the bond and the abrasive. With the continuous development of the polymer material industry, the development of the resin bonded grinding wheel is rapid. The resin bonded grinding wheel is in It is often used in polishing, fine grinding, etc. in the grinding process. It has superior characteris...
