preparation example Construction

[0054] see figure 1 , the invention provides a method for preparing a matte translucent blue electrophoretic aluminum profile, comprising the following steps:

[0055] S101, performing anodic oxidation on the pretreated aluminum profile, forming an oxide film on the surface of the aluminum profile.

[0056] S102, performing coloring treatment on the anodized aluminum profile in a coloring tank, so that coloring ions enter into pores of the oxide film.

[0057] The colored bath liquid is composed of nickel sulfate and boric acid, wherein the concentration of nickel sulfate is 140-150 g / L, and the concentration of boric acid is 38-42 g / L. The voltage of the coloring tank is 17-21V, the temperature is 24-26°C, the pH of the tank solution is 3.8-4.5, and the aluminum ion is controlled below 100ppm. Moreover, the coloring process uses a polarity inversion rectifier to exchange positive and negative currents, so that nickel ions in the bath solution enter the pores of the oxide fi...

Abstract

The invention discloses a preparation method of an extinction translucent blue electrophoresis aluminium profile. The preparation method comprises the following steps: carrying out anodic oxidation on the preprocessed aluminium profile, and forming an oxidation film on the surface of the aluminium profile; carrying out shading on the aluminium profile after anodic oxidation inside a coloring tank, so that coloring ions enter a film hole of the oxidation film; carrying out washing treatment on the colored aluminium profile; carrying out electrophoretic treatment on the washed aluminium profile inside a paint; forming an electrophoresis paint coating at the surface of the aluminium profile, wherein the electrophoresis paint coating is a translucent film layer; the paint comprises a gloss paint and an extinction paint; and the ratio of the gloss paint to the extinction paint is 1:4. Correspondingly, the invention also discloses the extinction translucent blue electrophoresis aluminium profile prepared by adopting the method. By adopting the preparation method, the aluminium profile is unique and beautiful in color, and does not generate light pollution.

Description

technical field [0001] The invention relates to the technical field of aluminum profiles, in particular to a matting translucent blue electrophoretic aluminum profile and a preparation method thereof. Background technique [0002] At present, my country is a big consumer of aluminum, and in the construction aluminum profile industry, oxidation electrophoresis products account for a large proportion. But most of them are light-transparent electrophoresis, the market competition is fierce, the color is relatively monotonous, the color is not beautiful enough, and the light pollution is serious, which affects the comfort of life. For example, in CN1920112 B disclosed "dye dip-coating compound treatment method on the surface of aluminum profiles", it is first chemically dyed, and then dip-coated with paint, so that the paint enters the pores of the oxide film. However, the paint used is a high gloss clear thermosetting acrylic paint or a matte clear thermosetting acrylic paint,...
