Abstract

An improved ceramic grinding agent is prepared from raw materials in parts by weight as follows: 10-14 parts of sodium metasilicate pentahydrate, 2-4 parts of sorbitan fatty acid ester, 3-5 parts of a surfactant, 6-8 parts of magnesium sulfate, 7-10 parts of talc, 11-16 parts of organic nano-montmorillonite, 1.2-3 parts of zirconia, 4-9 parts of ethylenediaminetetraacetic acid disodium salt, 8-11 parts of calcium carbonate, 12-18 parts of silicon carbide, 6-11 parts of polyvinyl alcohol, 4-9 parts of calcium stearate, 2-4 parts of an anti-aging agent, 3.1-5 parts of a molecular sieve, 8-15 parts of dodecenylsuccinic acid, 0.6-1.4 parts of ammonia water and 2.5-7 parts of white oil. The ceramic grinding agent has the benefits as follows: the agent can improve the ceramic precision, has good grinding effect and higher efficiency, and little ceramic deformation is caused.

Description

technical field [0001] The present invention relates to an improved ceramic abrasive. Background technique [0002] With the wide application of ceramic components in engineering, such as cutting tools, automotive valve packaging (sealing), element bearings, piston rotors, etc., the role of advanced ceramic grinding in grinding processing has increased. The improved performance and better efficiency of ceramic components over corresponding metals has many advantages. However, the favorable properties are accompanied by difficulties during machining, mainly related to the grinding of these advanced ceramics and the demands required for precision and surface quality of ground components with high hardness and stiffness. It is an important process forming for brittle materials to obtain good surface finish and high dimensional precision grinding. In order to ensure that the ceramic components have good precision and smoothness, it is necessary to grind the ceramic components....
