Abstract

The invention relates to a thermosetting phenolic resin abrasive cutting wheel and a preparation method thereof, and belongs to the technical field of abrasive cutting wheel production. The abrasive cutting wheel comprises a grinding body and a reinforcing mesh embedded in the grinding body, and the grinding body is prepared from, by weight, a raw material A and a raw material B; the raw materialA comprises microcrystalline corundum, brown fused alumina, cryolite, manganese alumina spinel, boron carbide, ultrafine powder, gypsum and a wetting agent; the raw material B is thermosetting phenolic resin powder, and the addition amount of the thermosetting phenolic resin powder is 20-30% of the total weight of the raw material A. According to the abrasive cutting wheel, through cooperation ofthe raw materials, the abrasive cutting wheel has high sharpness, high grinding efficiency and high rotation strength, and the service life of the abrasive cutting wheel is prolonged. According to thepreparation method of the abrasive cutting wheel, abrasive cutting wheel preparation is stable, the bonding strength between the raw materials is improved, and the use effect of the abrasive cuttingwheel is improved.

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...
