Abstract

The invention discloses electrolytic coloring liquid of an aluminum profile and a preparation method, application and application method thereof and belongs to the technical field of aluminum profile surface treatment. The electrolytic coloring liquid of the aluminum profile is composed of pure sulfuric acid, stannous mono-sulphate, nickel sulfate, coloring additives and water, the mass concentration of the pure sulfuric acid is 15-18 g/L, the mass concentration of the stannous mono-sulphate is 8-12 g/L, the mass concentration of the nickel sulfate is 15-30 g/L, and the mass concentration of the coloring additives is 20-30 g/L; the coloring additives are composed of D-tartaric acid, catechol, boric acid and sulfamic acid, and the coloring additives are composed of, by mass, 30%-40% of the D-tartaric acid, 30%-40% of the catechol, 20%-30% of the boric acid and 5%-10% of the sulfamic acid. By means of the electrolytic coloring liquid of the aluminum profile, a series of bright colors, namely light bronze to dark bronze to black, can be generated, the coloring of the aluminum profile is uniform, bright, little in chromatic aberration and good in reproducibility, a bath solution can keep clear and transparent for a long time, the dispersion capacity of the bath solution is great, the stability of tin ions is high, and the consumption is low.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile surface treatment, and more specifically relates to an aluminum profile electrolytic coloring solution and its preparation method, application and application method. Background technique [0002] Aluminum alloy extrusion profiles are widely used, and its surface treatment technology has achieved rapid development. In order to improve the protection and decoration performance of aluminum alloy profiles, it is necessary to carry out anodic oxidation and coloring treatment on aluminum alloy materials. The coloring methods of aluminum alloy after oxidation generally include chemical dyeing method, natural coloring method and electrolytic coloring method. In the 1960s, Asada in Japan invented the secondary electrolytic coloring method. The light resistance, heat resistance, wear resistance and corrosion resistance of the coloring film of this method were significantly improved compared with t...
