Problems solved by technology

At present, most of the processing enterprises engaged in glass polishing use the purchase of polishing powder, which is mixed with water by themselves. Although the quality is controlled according to the density in this process, the suspension of the polishing powder is poor and the precision is not accurate enough. Deviation, resulting in a greater impact on the quality of subsequent processing

Abstract

The invention discloses a glass polishing solution capable of improving the yield and reducing the dosage. The glass polishing solution comprises, by weight, 50-55% of rare earth metal oxide powder, 2-5% of a suspending agent, 0.2-0.5% of montmorillonite, 5-10% of a cosolvent, 5-10% of PEG40, and the balance of deionized water. The preparedglass polishing solution can effectively reduce the use amount of rare earth metal oxides in the production process, improves the yield of glass polishing, reduces the difficulty of the subsequent cleaning process, enables the polished glass product to be easy to clean, and shortens the cleaning process time by half, and the preparation method has the advantages of simplicity, intuition, less material loss, good economic benefit and wide application prospect. The glass polishing solution can be widely applied to products such as instrument glass, electronic 5G glass, automobile central control glass, watches and lenses.

Description

technical field [0001] The invention discloses a glass polishing solution with improved yield rate and reduced dosage and a preparation method thereof, belonging to the technical field of glass polishing solution. Background technique [0002] With the increasing demand for mobile phones and tablet computers, the demand for glass is gradually increasing. In the glass processing industry, glass needs to be polished in various ways. Among various polishing materials, oxides of rare earth metals are the main ones, and rare earth The abundance of metals in the earth is very low, which requires limited development and use, so reducing the use of rare earth metals is the starting point of this invention. If the polishing yield can be improved, rework or scrap can be reduced, the use of rare earth metals can also be reduced . At present, most of the processing enterprises engaged in glass polishing use the purchase of polishing powder, which is mixed with water and used after mixi...
