Abstract

A disclosed antibacterial mixed polishing solution for aluminium and aluminium alloy is characterized by being prepared from the following raw materials in parts by weight: 9-11 parts of cerium oxalate, 3-5 parts of dioctadecyl dimethyl ammonium chloride, 4-6 parts of 1-hydroxyethyl-2-tridecanyl imidazoline, 1.5-2 parts of di-n-butyl phosphite, 2-3 parts of menthol, 0.7-1.5 parts of stannous sulfate, 2-3 parts of sodium gluconate, 4-6 parts of glacial acetate acid, 3-5 parts of urea, 5-7 parts of an auxiliary agent, and 300 parts of deionized water. Added dioctadecyl dimethyl ammonium chloride has antibacterial efficacy and is capable of forming an easily-adsorbed surface layer on an aluminium alloy processing surface; and the added auxiliary agent is capable of forming a protective membrane layer on a metal surface and preventing air from corroding the metal surface. The mixed polishing solution is resistant to bacteria, resistant to corrosion, excellent in polishing property and bright in surface, and the polishing solution is an aqueous solution, and is capable of substantially reducing temperature caused by friction during polishing and giving play to cooling effect.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to an aluminum and aluminum alloy mixed polishing liquid with antibacterial effect and a preparation method thereof. Background technique [0002] The method of chemical polishing of aluminum and aluminum alloys is widely used, but the biggest disadvantage is that due to the high temperature of the polishing liquid and the fast reaction, it takes a long time for one station to go to the next during production on an automatic line, resulting in workpieces from After the chemical polishing tank comes out, it carries a large amount of residual chemical polishing liquid and stays in the air. During the process of the residual liquid flowing down and falling, the surface is corroded and oxidized to form different colors on the surface due to the existence of air, and because the polishing liquid contains Mixed oils are prone to spoilage and deterioration, which affects product ...
