Aluminum alloy surface treatment method and aluminum alloy surface treatment product

Abstract

The invention discloses an aluminum alloy surface treatment method and an aluminum alloy surface treatment product. The method comprises the following steps of: stamping an aluminum alloy piece to be in a required shape; performing partial mirror polishing on the stamped aluminum alloy piece to achieve a mirror effect; printing ink in a mirror region, and baking; sanding the treated aluminum alloy piece to enable an ink-unprinted region to be sandy; neutralizing and chemically polishing the sanded aluminum alloy piece; removing the ink from the treated aluminum alloy piece; placing the treated aluminum alloy piece into an acid liquor groove for anodizing; neutralizing the anodized aluminum alloy piece, and performing dyeing and hole-sealing treatment to obtain a required product. The product is an aluminum alloy product which is generated through the aluminum alloy surface treatment method. The surface of the product has the mirror effect and a sandy effect through one-time anodizing, the method is short in manufacturing process and high in efficiency, and the production cost can be saved.

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 few products with both sandy texture and mirror effect; Products with a mirror effect require a combination of sandblasting and polishing. During the sandblasting process, sandblasting marks are easily produced on the surface of the product, and because the mirror anode process after polishing is different from the sandblasting anode process, the ...

[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 few products with both sandy texture and mirror effect; Products with a mirror effect require a combination of sandblasting and polishing. During the sandblasting process, sandblasting marks are easily produced on the surface of the product, and because the mirror anode process after polishing is different from the sandblasting anode process, the primary anode is used. The manufacturing process cannot present the effect of mirror surface and sandblasting, and requires two anodic oxidations. The manufacturing process is long and the efficiency is low.
