Abstract

The invention provides a preparation method of an anti-damping resin grinding wheel. The preparation method of the anti-damping resin grinding wheel comprises 0.5-1.0 mass part of silane coupling agent, 8-12 mass parts of phenolic resin liquid, 50-80 mass parts of 46# plated white corundum, 20-40 mass parts of 54# plated white corundum, 0.5-1.0 mass part of carbon black, 8-12 mass parts of potassium fluoroaluminate, 3-5 mass parts of calcium sulfate whiskers, and 18-23 mass parts of modified phenolic resin powder. Plated white corundum abrasives are adopted; high-temperature coating layers are arranged on the surfaces of the abrasives; the coating layers facilitate improvement of the resin and abrasive interface bonding strength; silane coupling agent molecules contain reaction radicals chemically bonded with inorganic matter materials, and reaction radicals chemically bonded with organic matter materials; inorganic and organic interfaces are bonded to promote the interface fusion to improve the performances; secondly, the modified phenolic resins adopted in the method contain no radicals easy to oxidize in molecular structures compared with general phenolic resins; and the free phenol content in the method is low, so that the performance degradation of hardened resins can be effectively relieved.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a method for preparing an anti-attenuation resin grinding wheel. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Abrasives, binders, and pores are the three basic components of grinding wheels. With different abrasives, binders, and grinding wheel manufacturing processes, the characteristics of grinding wheels may vary greatly, which affects the accuracy, roughness, and production efficiency of grinding. It has an important influence, therefore, the appropriate grinding wheel must be selected according to the specific conditions. [0003] Resin grinding wheel is a grinding wheel whose binder is resin. It has the advantages of small grinding force, low grinding temperature, good self-sharpening, and high grinding efficiency. It is widely used in the grinding of hard and brittle mat...
