Abstract

The invention provides an aluminum oxide polishing solution for alloy polishing. The aluminum oxide polishing solution contains the following components by mass: 1-40% of aluminum oxide, 0.2-1% of a surfactant polyacrylic acid, 0.2-2% of a corrosion inhibitor disodium hydrogen phosphate, 1-10% of a pH regulator, and 48-97.6% of deionized water. The aluminum oxide can be alpha aluminum oxide, the average particle size is 200-10000 nanometers, and the pH range of the polishing solution is preferably 2-4. The polishing solution is used for aluminum alloy or stainless steel substrate polishing, and can quickly realize alloy surface planarization.

Description

technical field [0001] The invention relates to the technical field of surface manufacturing and polishing of electronic products such as mobile phones and computers, in particular to an alumina polishing solution and a preparation method thereof, and the polishing solution is used for polishing treatment of alloy substrates. Background technique [0002] In recent years, metal alloys have been used more and more in the fields of electronic products such as mobile phone casings, computer casings, and frames. In these applications, metal alloy hair is generally first cut into a semi-finished product with a tool in a numerically controlled machine tool, and then undergoes several steps of surface grinding and polishing to achieve a mirror effect. The surface of the aluminum alloy cut by a knife has a large number of knife lines, that is, macro scratches. To achieve the global planarization and mirror effect of the aluminum alloy surface, chemical mechanical polishing is curre...
