Abstract

The invention discloses an aluminum alloy polishing solution and a preparation method thereof. The aluminum alloy polishing solution comprises 30%-50% of silicon sol, 0.5%-3% of a complexing agent, 0.02%-0.1% of a surfactant, 0.05%-0.5% of an inhibitor, 0.5%-2% of a brightener and the balance water. The particle size of the silicon sol is 80-140 nanometers, and the concentration of the silicon sol is 30%-50%. The invention further provides the preparation method of the aluminum alloy polishing solution. The preparation method comprises the steps that all the components and substances are taken, and the complexing agent, the surfactant, the inhibitor and the brightener are sequentially added into the silicon sol in proportion. According to the obtained aluminum alloy polishing solution, a protective film can be formed on the surface of aluminum alloy in the polishing process; the complexing agent with a buffer function is used, and thus the effect that the PH value of the solution is between nine and ten is ensured; the polishing function of the polishing solution is optimally played; the polishing effect is good; and the cycle use time is longer and is one to two times of that of a traditional aluminum alloy polishing solution.
