A method for forming a textured pattern on a metal surface

Abstract

The invention discloses a method for forming mesh lines on the metal surface. Hot melt glue silk is adopted for manufacturing a mesh film of a mesh line structure, the mesh film is used as a shielding layer, a first paint layer is formed in the zone not shielded by the mesh film through primary electrophoresis, a second paint layer with the color being different from that of the first paint layer is deposited on the zone covered with the mesh film through secondary electrophoresis after the mesh film is removed, and thus the mesh line structure of the mesh film is transferred to the metal surface. The hot melt glue mesh film can be removed through simple methods such as hot water dissolution and organic solvent swelling dissolution and cleaning instead of strong base or other corrosive substances, and influences on a paint film structure are avoided; and meanwhile, various mesh line patterns can be formed as required, the processing procedure is simple, and the application range is enlarged.

Description

technical field [0001] The invention relates to a metal surface treatment method, in particular to a method for forming a decorative mesh pattern on the metal surface. Background technique [0002] The monotonous metallic or single-color paint surface of metal products can no longer meet people's needs for diversified product appearance. Therefore, while protecting the surface of metal products, a colorful decorative pattern appearance is formed to manufacture decorative products and unify the style with other parts High-quality products or novel and beautiful products are gradually being valued, and their production processes are also developing day by day. [0003] The existing pattern appearance production methods include surface spray coating, thermal transfer pattern, printing, etc. The decorative ink layer in these methods is separated from the primer, and only exists on the surface of the product without penetrating the primer, which is very easy to be damaged due to ...

AI Technical Summary

Problems solved by technology

When cleaning the ink, strong alkali or other corrosive substances must be used as cleaning agents, which will cause damage to the primary electrophoretic film layer, thus greatly affecting its performance and appearance

[0005] In addition, fine patterns, such as textured patterns, require high graphics resolution. Existing inks often use screen printing, which has a low resolution and is difficult to produce textured patterns, let alone achieve natural The effect of disordered texture limits its application

In addition, screen printing needs to design different screens to achieve different patterns, switching between screens and cleaning and maintenance are troublesome and costly
