Problems solved by technology

[0002] Now, aluminum alloy has been the most widely used alloy metal, especially in the computer, mobile phone and other electronic equipment industries. It can be dyed to improve the decoration. When it is necessary to obtain a mirror transparent effect, the existing process often uses a cloth wheel polishing process to obtain a transparent mirror effect after anodizing. However, the existing cloth wheel polishing process is in the process of polishing During the process, it is easy to have poor heat dissipation during polishing, severe orange peel on the surface of the product after polishing, shedding of the anode film, and extremely unstable color fading process, resulting in low yield rate. Therefore, the existing aluminum alloy products have great limitations in use, which greatly limits its application in the electronic product industry

Embodiment 1

[0025] A surface mirror treatment process of aluminum alloy, comprising the following process steps:

[0026] S1. Grinding the surface of the aluminum alloy product to remove the material texture on the surface of the product to achieve a mirror finish;

[0027] S2. Cleaning the aluminum alloy products;

[0028] S3. Carrying out anodic oxidation treatment to the aluminum alloy product; after the anodic oxidation treatment, a layer of anodic oxidation film is formed on the surface of the aluminum alloy, and the anodic oxidation film can be a transparent or translucent film according to the needs of the product. It is best to seal the aluminum alloy products for the first time. The first hole sealing is processed by cold sealing, which is beneficial to quickly send the sealed aluminum alloy product to the next processing procedure.

Abstract

The invention relates to the technical field of metal surface treatment, and particularly relates to a surface mirror treatment technique for aluminum alloy. The surface mirror treatment technique comprises the steps that S1, the surface of an aluminum alloy product is ground, material lines of the surface of the product are removed, and the mirror finish degree is reached; S2, the aluminum alloy product is cleaned; S3, the aluminum alloy product is subjected to anodizing treatment; S4, the aluminum alloy product is sent into magnetorheological polishing equipment for magnetorheological polishing treatment, and a highlight transparent oxidation film is obtained; S6, the aluminum alloy product subjected to magnetorheological polishing is cleaned and then subjected to hole sealing treatment; and S7, the surface mirror treatment technique is completed. According to the treatment technique, the aluminum alloy product is anodized at first and then subjected to the first time of hole sealing, and magnetorheological polishing is conducted, so that manufacturing of aluminum alloy with the mirror effect can be achieved through the magnetorheological polishing technique. Meanwhile, the yield is high, and the surface treatment effect is good.
