Ceramic cutting tool material with high mechanical strength and preparation method therefor
The present invention discloses a ceramic cutting tool material with high mechanical strength and a preparation method therefor. The ceramic cutting tool material is prepared from the following raw materials in parts by weight: 50-70 parts of silicon dioxide, 10-12 parts of nanometer aluminium oxide, 6-8 parts of Huangxiu Stone (a type of China's granite), 1-2 parts of sodium fluoride, 1-2 parts of polyacrylic acid, 2-4 parts of magnesium borate whiskers, 15-25 parts of coal ash, 2-3 parts of glycerin, 3-5 parts of triglycidyl ester, 4-6 parts of a borate coupling agent, 2-4 parts of antimony trichloride, 1-2 parts of phosphorus pentoxide, 2-3 parts of phenolic resin emulsion, 2-4 parts of butanediol, and 6-7 parts of an auxiliary agent. According to the present invention, the ceramic cutting tool material takes silicon dioxide as a main raw material; the raw materials such as magnesium borate whiskers, Huangxiu Stone, and nanometer aluminium oxide, are added, so that the integral mechanical strength of the ceramic cutting tool material is improved and the corrosion resistance and the heat resistance of the ceramic cutting tool material can be further improved. Moreover, the ceramic cutting tool material is long in service life, and the using cost is reduced.
