Problems solved by technology

[0002] The existing polishing fluid using silica hydrosol as abrasive has the advantages of high material removal rate, extremely low scratch and particle residue, good fluidity and stability, and is a kind of polishing fluid that can achieve global planarization. An effective method, but because the nano-scale silica particles will gradually gel below zero, the coagulum will not return to the original dispersed state after thawing, which makes it impossible to apply to production, which is very inconvenient. Therefore, in order to solve the above problems, a A kind of antifreeze type polishing liquid and preparation method thereof are very necessary

Abstract

The invention discloses an anti-freezing polishing solution, and a preparation method thereof. The anti-freezing polishing solution comprises, by weight, 30 to 90 parts of saturated biological ion active water, 10 to 30 parts of silica sol, 5 to 10 parts of a nonionic surfactant, 5 to 15 parts of a pH conditioning agent, 50 to 60 parts of glycol, and 0.05 to 5 parts of methylene blue. The anti-freezing polishing solution is excellent in anti-freezing effect; and the preparation method is simple, is safe, and is friendly to the environment.

Description

technical field [0001] The invention relates to an antifreeze polishing liquid, in particular to an antifreeze type polishing liquid and a preparation method thereof. Background technique [0002] The existing polishing fluid using silica hydrosol as abrasive has the advantages of high material removal rate, extremely low scratch and particle residue, good fluidity and stability, and is a kind of polishing fluid that can achieve global planarization. An effective method, but because the nano-scale silica particles will gradually gel below zero, the coagulum will not return to the original dispersed state after thawing, resulting in the inability to be used in production, which is very inconvenient. Therefore, in order to solve the above problems, a It is necessary to provide an antifreeze type polishing liquid and a preparation method thereof. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provi...
