Embodiment Construction

[0007] In order to achieve the brightness and realistic color of aluminum products, mechanical polishing, electrolytic polishing and other pre-treatments must be carried out on the colored surface before oxidation with sulfuric acid solution. The thickness of the oxide film is at least 6 microns, so the oxidation time must be In 30min. The oxidized aluminum material is colored with soluble reducing pigments, which consists of two processes of coloring and color development.

[0008] Adhesion: Spray titanium dioxide powder on aluminum products to form a thin film.

[0009] Coloring: lysanthracene golden IGK: 0.035g / L, lysine orange IRK: 0.1 g / L; PH (adjusted with acetic acid): 4-5; temperature: room temperature.

[0010] Add the calculated amount of the above two pigments to a little cold water to make a paste, dissolve it evenly with boiling water, then pour it into the color tank, dilute to the required volume, adjust the pH value to the process range with acetic acid, and...

Abstract

The invention provides a coloring process of an aluminum oxide material, which belongs to the field of metal surface treatment. The surface to be colored of an aluminum product workpiece is firstly mechanically polished; after the electrolytic polishing treatment is conducted, the surface of the aluminum product workpiece is oxidized by using sulfuric acid liquid for 30min, so as to enable a shining oxidation film with a thickness of 6 microns to 7 microns to be formed on the surface of the aluminum product workpiece; and functional substance particles are adopted to be attached to the surface of the aluminum product workpiece, and then the surface of the aluminum product workpiece is dyed by using inorganic pigments. After being polished and oxidized, a product can be attached by various inorganic pigment colors and has the healthy functions of antibiosis, and far infrared or magnetic therapy.

Description

technical field [0001] The invention relates to a coloring process of alumina material, which belongs to the field of metal surface treatment. Background technique [0002] Due to the rich aluminum resources in our country, the development of aluminum products has been more and more recognized by people. Such as household aluminum door [0003] Aluminum products such as windows and decorative materials are widely welcomed by people. However, due to the single color tone and single function of the current aluminum products, the use of aluminum materials is limited. Due to the improvement of people's living standards, home decoration is also more magnificent, the requirements for color are gradually increasing, and the requirements for functions are also gradually being emphasized. Functional multi-color metal materials are more popular among people. Contents of the invention [0004] In view of the defects in the prior art, the invention provides a coloring process f...
