Problems solved by technology

Due to the limitations of the process, the wood-grain profile has uneven coating thickness, and the groove part cannot be powdered, which will leak the background color of the substrate and affect the appearance quality
In addition, the weakness of the thermosetting organic polymer material itself is that compared with the electrophoretic profile, it is easy to powder and fade, the weather resistance of the coating is poor, and the gloss is significantly lower than that of the electrophoretic profile.

Abstract

The invention relates to a manufacturing method of an aluminum alloy electrophoresis wood grain profile, comprising the following multiple steps of: degreasing the conventional aluminium alloy base materials; washing; carrying out acid etch; washing; carrying out alkali etch; washing; neutralizing; washing; carrying out anodic oxidation; washing; washing by using pure water; carrying out electrolytic coloring; washing; washing by using the pure water; washing by using hot water; carrying out electrophoresis; washing; washing; dripping for drying; curing; and carrying out transfer printing on wood grains. The manufacturing method of the aluminum alloy electrophoresis wood grain profile is characterized in that the curing temperature of electrophoretic paint is 190-200 DEG C, and the curing time is 24-26 minutes; the transfer printing temperature is 185-190 DEG C, and the transfer printing time is 23-23.5 minutes, thus an aluminum alloy electrophoresis wood grain profile product is obtained. The aluminum alloy electrophoresis wood grain profile product has uniform coating, high adhesive force and good coverage, thereby preventing the appearance defects caused by the bottom leakage of a powder coating; and in addition, the invention has the advantages of high glossiness, brilliant and beautiful color, wonderful feeling of color change and diversity, high corrosion resistant capacity, good weather resistance and difficulty of chalking or fading.

Description

technical field [0001] The invention relates to a method for manufacturing an aluminum alloy electrophoretic wood grain profile, which belongs to the field of surface treatment of aluminum alloy profiles. Background technique [0002] The existing surface treatment of aluminum alloy has a kind of electrophoretic paint profile. Electrophoretic paint is to anodize the aluminum alloy substrate to form dense micro-pores with a depth of about 10um. It is deposited in the oxidation pores, and after electrophoresis, the water-soluble varnish or colored paint is deposited on the surface of the profile to form a uniform, flat and smooth paint film, and the metal particles or organic dyes are sealed in the oxidation pores to make a product. . Electrophoretic painting has the advantages of uniform coating, strong adhesion, good coverage, strong corrosion resistance, good weather resistance, and is not easy to pulverize and fade. However, the color of the paint film is also subject to...
