Preparation method of zirconia grinding fluid

Abstract

The invention discloses a preparation method of a zirconia grinding fluid, and relates to the technical field of new materials applied in precision grinding and polishing technical fields. The preparation method comprises the processes: adding a wetting and dispersing agent to high-speed dispersed water in parts by weight, then adding zirconia powder and auxiliary materials, fully dispersing, introducing into a high-speed sanding machine for sanding to grind the edge of zirconia powder into a round spherical shape, adding functional additives when the particle size of the zirconia powder reaches a certain value, and then adding a coloring agent to adjust the color. The zirconia grinding fluid has the characteristics of free from influence of particle size and shape of zirconia raw materials, lower production cost and good stability, is suitable for the precision grinding and polishing of liquid crystal electroconductive glass, flat optical glass, optical spherical and optical lens glass, filters, filter windows and glass plate substrates, and is especially suitable for the grinding and polishing of soft material spherical glass.

Description

technical field [0001] The invention relates to the technical field of new materials, and is applied in the technical field of precision grinding and polishing, in particular to a preparation method of zirconia grinding fluid. Background technique [0002] Zirconia mineral raw materials in nature mainly include baddeleyite and zircon. Zircon is a deep mineral in igneous rocks. Its color is light yellow, brown yellow, yellow green, etc., with a specific gravity of 4.6-4.7 and a Mohs hardness of 7.5. It has a strong metallic luster. Zirconia has the characteristics of high temperature resistance, chemical corrosion resistance, oxidation resistance, wear resistance, large thermal expansion coefficient, small specific heat and thermal conductivity, so it is an ideal high temperature refractory material, abrasive material and high temperature insulation Material. Zirconia and alumina are mixed to make coarse abrasive particles, which can be used to make grinding wheels and coat...

Problems solved by technology

Zirconia is a soft abrasive, mainly used for the grinding and polishing of spherical glass made of soft materials. The existing abrasives in the domestic and foreign markets are products of Flow, the United States. The zirconia abrasive liquid is zirconia powder (D50: 1.15-1.60UM , D100≤5.60UM) dispersed in the water phase, adding auxiliary materials and colorants, such as alcohols, esters, to play the role of emulsification, lubrication and adsorption dispersion, the product has a good grinding effect, but due to the At the same time, the particle size and shape of the zirconia powder raw material are required to be high, so the production cost is high and the price is expensive.

Chinese patent (application number 200910044264.6) "a production process of zirconia grinding liquid", its production process is as follows: add zirconia powder in high-speed dispersed water according to weight ratio, then add wetting and dispersing agent, grinding aid and mixed grease Alcohols and alcohols, after being fully dispersed, enter the high-speed sand mill for sand grinding, grind the corners of the zirconia powder into a rounded spherical shape, and then add colorants to adjust the color; Size and shape influence and low production cost. Its products can be used for grinding and polishing of lenses, flat glass, glass shells, glasses, watch cases, display screens, etc., but when used in the grinding and polishing of soft spherical glass, it is still Arabian phenomenon
