Preparation method for zirconium dioxide ball-milling medium

Abstract

A preparation method for a zirconium dioxide ball-milling medium comprises the following steps: providing yttrium-stabilized tetragonal zirconia powder, deionized water, a crosslinking agent, a monomer, a dispersing agent, an initiator, a catalyst and an oil phase forming agent; stirring and mixing the monomer, the crosslinking agent, the dispersing agent and the deionized water so as to obtain a pre-preparation mixed solution; carrying out ball milling on the pre-preparation mixed solution and the yttrium-stabilized tetragonal zirconia powder on a planetary ball mill, so as to obtain pre-preparation slurry; carrying out ball milling on the pre-preparation slurry and the initiator so as to obtain zirconium dioxide ceramic slurry; spraying out the zirconium dioxide ceramic slurry and the catalyst in a liquid drop manner by using a spraying process, and after the liquid drops of the zirconium dioxide ceramic slurry and the catalyst are mixed, spraying the mixed liquid drops into the oil phase forming agent; filtering, washing and drying so as to obtain a prefabricated zirconium dioxide ball-milling medium blank; sintering the prefabricated zirconium dioxide ball-milling medium blank so as to obtain the submillimeter-level zirconium dioxide ball-milling medium. The preparation method has the advantages of relatively simple preparation process and relatively low cost.

Description

technical field [0001] The invention relates to the technical field of ball milling media preparation, in particular to a preparation method of zirconia ball milling media. Background technique [0002] At present, as the main equipment in the crushing and grinding of mineral materials, the ball mill has been widely used in the crushing of mineral materials in many industries such as metallurgy, building materials, and chemical industry. Since it came out in 1893, it has a history of more than 100 years. , has made outstanding contributions to the development of human civilization. [0003] Among them, the grinding ball stone is a ball or cylindrical object rolling in the ball mill, commonly known as the ball mill medium. Especially in the ceramic production industry, ceramic ball milling media are mainly used. Zirconia ball milling media stands out among the series of ceramic ball milling media due to its high strength, high hardness, excellent wear resistance and corrosio...

AI Technical Summary

Problems solved by technology

[0006] The traditional preparation methods of submillimeter zirconia ceramic balls mainly include mold pressing method, isostatic pressing method, atomization method and spray granulation method, but the existing preparation methods still have poor relative density and low mechanical strength. defects, and the above-mentioned preparation method generally has the problems of complex process and high cost
