Abstract
The invention relates to the technical field of grinding wheel manfuacuting and particularly relates to a urea-containing ceramic fused alumina zirconia grinding wheel and a production process thereof. The grinding wheel is prepared from the following raw materials in parts by weight: 40-42 parts of white corundum grinding material, 50-54 parts of fused alumina zirconia grinding material, 10-12 parts of clay powder, 3-4 parts of potassium feldspar powder, 4-5 parts of pottery clay, 2-3 parts of zinc oxide, 3-4 parts of urea, 1-2 parts of diammonium orthophosphate, 2-3 parts of potassium chloride and 7-9 parts of accessory ingredient. According to the production process, the raw materials such as the clay powder and the potassium feldspar powder are used for preparing a ceramic bond with stable performance and small thermal-expansion coefficient; furthermore, by virtue of the raw materials such as urea and diammonium orthophosphate, the holding strength and gas hole ratio of the grinding materials are enhanced, and the grinding wheel is rapid in heat dissipation during a high-speed grinding process. The fused alumina zirconia grinding wheel prepared by virtue of the production process not only has improved rigidity, but also has effectively-improved grinding performance; compared with a traditional fused alumina zirconia grinding wheel, the fused alumina zirconia grinding wheel prepared by virtue of the production process is longer in service life.
