Abstract

Disclosed is an abrasive tool made of epoxy resin-bonded compound abrasive material, which comprises epoxy resin, abrasive material and curing agent. The weight percentages are as follow: the epoxy resin is 15 to 78 percent, the abrasive material is 2 to 44 percent and the curing agent is 4 to 18 percent. Wherein, the abrasive material comprises one of diamond, silicon carbide or corundum or the combination of more than one material. The curing agent comprises one of 4.4`-methylenedianil, solid diaminodiphenyl methane or liquid modified diaminodiphenyl methane or the combination of more than one material. The component of the abrasive tool also comprises the other auxiliary material, which comprises one of alumina, barium chloride, sodium chloride, quartz sand, organobentonite, wetting agent, zirconium silicate, calcium carbonate, graphite powder, garnet, magnesium sulfate, phenolic resin, zinc stearate and magnesium stearate, or the combination of more than one material. The product can be made into any shape the same with the present product, which can be applied in various grinding and polishing equipment with wide application scope.

Description
