A kind of thermosetting phenolic resin cutting wheel and preparation method thereof

Abstract

The invention relates to a thermosetting phenolic resin cutting grinding wheel and a preparation method thereof, belonging to the technical field of cutting grinding wheel production. The cutting grinding wheel includes a grinding body and a reinforcing mesh embedded in the grinding body. In terms of weight percentage, the raw materials of the grinding body include Raw material A, raw material B; raw material A includes microcrystalline corundum, brown corundum, cryolite, manganese aluminum spinel, boron carbide, ultrafine powder, gypsum, wetting agent; raw material B is thermosetting phenolic resin powder, thermosetting phenolic resin powder The addition amount is 20-30% of raw material A gross weight. The cutting grinding wheel, through the synergy between the raw materials, enables the cutting grinding wheel to have higher sharpness and grinding efficiency, and also has higher gyration strength, which improves the service life of the cutting grinding wheel. The preparation method of the cutting grinding wheel not only makes the preparation of the cutting grinding wheel stable, but also increases the bonding strength between raw materials and improves the use effect of the cutting grinding wheel.

Description

technical field

[0001] The invention relates to the technical field of cutting grinding wheel production, more specifically, it relates to a thermosetting phenolic resin cutting grinding wheel and a preparation method thereof. Background technique

[0002] Grinding wheel is the main tool for grinding. It is a porous substance composed of abrasives, fillers, and binders. It is widely used in metallurgy, construction, railways and other fields. It is mainly used for cutting and grinding steel pipes, shaped pipes, and steel bars. At present, in the process of cutting metal with the grinding wheel, in order to increase the abrasion and lubrication of the grinding wheel and reduce the wear of the grinding wheel, pyrite is generally added to the raw material of the grinding wheel. The main component of pyrite is iron disulfide, adding disulfide Although iron can reduce the wear of grinding wheels, iron disulfide is easily oxidized by oxygen in the air to produce sulfur dioxide and...
