Embodiment 1

[0068] This embodiment provides an aluminum alloy plate, which is obtained by performing anti-perspiration treatment according to the following steps:

[0069] (1) Provide an aluminum alloy plate that has undergone degreasing, alkali etching and polishing treatment, and anodize the aluminum alloy plate with an anodic oxidation treatment solution, so that an oxide film with holes is formed on the surface of the aluminum alloy plate. The oxidation voltage of the oxidation treatment is 15V, the oxidation temperature is 8°C, and the oxidation time is 60 minutes; in the anodizing treatment solution, the concentration of sulfuric acid is 200g / L, Al 3+ The concentration is 12g / L;

[0070] (2) Place the anodized aluminum alloy plate in an organic dye solution for dyeing, wherein in the organic dye solution, the concentration of the organic dye is 1-3g / L, the pH value is 6-7, and the dyeing at room temperature is 300-600s ;

[0071] (3) Place the dyed aluminum alloy plate in the seal...

Embodiment 2

[0074] This embodiment provides a perspiration-resistant aluminum alloy plate. The difference between this embodiment and Embodiment 1 is that in step (1), the oxidation voltage of the anodic oxidation treatment is 12V, the oxidation temperature is 10°C, and the oxidation time is 55 minutes.

Embodiment 3

[0076] This embodiment provides a perspiration-resistant aluminum alloy plate. The difference between this embodiment and Embodiment 1 is that in step (1), the oxidation voltage of the anodic oxidation treatment is 18V, the oxidation temperature is 5°C, and the oxidation time is 65 minutes.

Abstract

The invention provides a metal plate anti-perspiration treatment process, metal plate, metal shell and electronic equipment, and relates to the technical field of metal plate surface treatment. The metal plate anti-perspiration treatment process includes the following steps: sequentially treating the metal plate Anodizing, dyeing and sealing treatment, wherein the oxidation voltage of the anodizing treatment is 12-18V, the oxidation temperature is 5-10°C, and the oxidation time is 55-65 minutes; it improves the adhesion of sweat stains on the metal shell and causes the metal shell Body corrosion and fading, technical problems that affect the aesthetics and user experience of electronic equipment. The metal plate obtained after the anti-sweat treatment process of the metal plate provided by the present invention has significantly improved anti-sweat corrosion ability, so that the metal plate is not easy to age and fade, so that after it is prepared into a metal shell, the use stability of electronic equipment can be effectively guaranteed. and user experience.

Description

technical field [0001] The invention relates to the technical field of surface treatment of metal plates, in particular to an anti-perspiration treatment process for metal plates, metal plates, metal casings and electronic equipment. Background technique [0002] In existing electronic devices, metal shells are more and more widely used because of their good physical properties and beautiful appearance. However, the metal casing needs to be in frequent contact with the hands, especially in hot weather. The sweat on the hands will often adhere to the metal casing, causing the metal casing to corrode and fade, affecting the aesthetics and user experience of electronic devices. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a surface treatment process for metal plates to improve the metal shell that needs to be in frequent contact with hands, and the sweat stains on the hands ...
