A kind of aluminum alloy anodic oxidation surface black gold wood grain production process and product

Abstract

The invention discloses a production process of a black gold wood grain in an anodic oxidation surface of an aluminum alloy and product, comprising a pretreatment process, an anodizing treatment, an electrolytic coloring, a hole sealing in medium temperature and a wood grain transfer process, wherein a black electrolytic bath solution is used in the electrolytic coloring process. After the electrolysis is completed, the wood grain substrate is a black electrolytic colored aluminum alloy profile, which combines with the gold grain wood grain formed by the subsequent wood grain transfer, and hasexcellent visual effect; and the surface of the profile is uniform in color, high in temperature resistance, heat and humidity resistance, abrasion resistance and outdoor weather resistance, acid andalkali resistance and ultraviolet radiation resistance after multiple processes.

Description

technical field [0001] The invention relates to surface treatment of aluminum alloys, in particular to a production process and product of black gold wood grain on the anodized surface of aluminum alloys. Background technique [0002] The traditional aluminum alloy wood grain production process is based on the ink penetration thermal transfer process on the surface of the aluminum alloy with a certain organic coating. The wood grain production process is cumbersome, the construction period is long, the labor cost is large, and the texture difference is large. , The technical level of the operator is high. At the same time, due to the large difference in weather resistance between the ink and the surface of the organic coating, the traditional thermal transfer wood grain texture will fade and fade after a period of exposure to the sun and rain. The light and anti-aging properties are average and cannot meet many specific requirements. In addition, there is still a big gap b...

[0002] The traditional aluminum alloy wood grain production process is based on the ink penetration thermal transfer process on the surface of the aluminum alloy with a certain organic coating. The wood grain production process is cumbersome, the construction period is long, the labor cost is large, and the texture difference is large. , Higher technical requirements for operators

At the same time, due to the large difference in weather resistance between the ink and the surface of the organic coating, the traditional thermal transfer wood grain texture will fade and fade after a period of exposure to the sun and rain. Light and anti-aging properties are average, unable to meet many specific requirements

In addition, there is still a big gap between traditional wood-grain aluminum profiles and high-end products visually, and the wood-grain effect is single, which limits its decoration and application range
