Embodiment Construction

[0031] For a further understanding of the purpose of the present invention, method steps and functions, please refer to figure 1 , and detailed as follows:

[0032] The invention provides a method for surface treatment of an aluminum alloy, which comprises the following steps:

[0033] Step 1001: Stamping the aluminum alloy into a desired shape, the aluminum alloy can be a series of 1 or series 2 or series 5 or series 6 or series 7;

[0034] Step 1002: mechanically polishing the stamped aluminum alloy to achieve a mirror effect;

[0035] Step 1003: Degrease the mechanically polished aluminum alloy in a degreasing agent with a concentration of 5% to 8%, to remove surface grease and polishing wax; perform light treatment on the degreased aluminum alloy to remove the surface oxide film, and perform light treatment The final aluminum alloy is neutralized, and the neutralization treatment uses a nitric acid solution with a concentration of 20-40% to remove the hydroxide black ash...

Abstract

The invention discloses a method for surface treatment of an aluminium alloy and a product of the aluminium alloy. The method comprises the steps of punching the aluminium alloy into a required shape; conducting mechanical polishing on the aluminium alloy which is subjected to punch forming; conducting degreasing treatment on the aluminium alloy which is subjected to mechanical polishing in a degreasing agent; placing the aluminium alloy which is subjected to degreasing treatment into an acid liquor tank for first-time anodic oxidation; placing the aluminium alloy which is subjected to first-time anodic oxidation into dye for dying, and conducting hole sealing treatment after dying; conducting screen printing on the surface of the aluminium alloy which is subjected to dying and hole sealing treatment with photosensitive ink, and conducting exposure, developing and photocuring treatment; conducting oxidation film removing treatment on the printed aluminium alloy in an alkaline solution; conducting sand blasting treatment on the treated product of the aluminium alloy; conducting second-time anodic oxidation on the product of the aluminium alloy, which is subjected to sand blasting treatment, and conducting hole sealing treatment on the product which is subjected to second-time anodic oxidation; and removing the photosensitive ink from the surface of the product of the aluminium alloy. The product of the aluminium alloy is processed by the method.

Description

【Technical field】 [0001] The invention relates to an aluminum alloy surface treatment method and its product, in particular to a surface treatment method and its product for obtaining mirror effect and sand surface effect on the aluminum alloy surface. 【Background technique】 [0002] Aluminum alloy anodized products with sand surface effect or mirror effect have been widely used in the fields of electronics, communication and consumer products, and are deeply loved by customers. [0003] However, most of the products currently on the market have only one kind of sandy texture effect, or only one kind of mirror effect, and there are almost no products with both sandy texture and mirror effect. [0004] In view of this, it is necessary to provide an aluminum alloy surface treatment method to obtain both a mirror effect and a sand surface effect on the surface of the aluminum alloy product. 【Content of invention】 [0005] In view of the above problems, the object of the pres...
