Abstract

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.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a ceramic tool material with high mechanical strength and a preparation method thereof. Background technique [0002] In the industrial world, cutting tools for metal processing are a very important product. Commonly used tool materials are divided into the following categories: (1) high-speed steel materials; (2) cemented carbide materials; (3) ceramic tool materials; (4) superhard tool materials. Ceramic materials have become one of the most promising high-speed cutting tool materials due to their excellent heat resistance, wear resistance and chemical stability, and have a wide range of application prospects in production. It plays an increasingly important role in the field of high-speed cutting and cutting difficult-to-machine materials. [0003] Ceramic cutting tools have the characteristics of high hardness, high density, high temperature resistance, anti-magne...
