Embodiment Construction

[0035] A three-color pattern electrophoresis method on a metal surface realizes the three-color electrophoresis process by combining a hot-melt adhesive mask and a masking ink.

[0036] Please refer to figure 1 , the following is a simple three-color pattern for illustration. Firstly, the masking ink 2 is coated on the first area of ​​the surface of the metal product 1 and dried. Preferably, the surface of the metal product can be pre-treated by polishing, copper plating, nickel plating or a combination thereof to facilitate subsequent electrophoresis. The masking ink is conventional ink, such as epoxy resin ink, and the coating method can be screen printing, pad printing, spraying, etc. to form a preset pattern, specifically, its thickness ranges from 10 μm to 50 μm. The drying temperature is 60°C-120°C, and the drying time is 10-30 minutes. After drying, the masking ink adheres to the surface of the metal product and solidifies.

[0037] Next, adhere the hot-melt adhesive...

Abstract

The invention discloses a metal surface three-color pattern electrophoresis method. According to the method, a hot-melt adhesive mask film and a masking ink are combined, and sub-region electrophoresis is performed by using different removing methods of the hot-melt adhesive mask film and the masking ink; and a first color paint is deposited on a uncovering region through electrophoresis, the hot-melt adhesive mask film is removed through hot water or organic solvent dissolving and washing and other ways, a second color paint is deposited on the original hot-melt adhesive mask film covering region through electrophoresis, the mashing ink is removed through alkali ultrasonic washing and other ways, and a third color paint is deposited on the original mashing ink covering region through electrophoresis so as to achieve the three-color electrophoresis process. With the method of the present invention, the three-color pattern can be formed, the problem impossibly achieved in the prior art is solved, the metal surface decoration is enriched, and the application range is expanded.

Description

technical field [0001] The invention relates to a metal surface treatment method, in particular to a three-color pattern electrophoresis method 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, heat transfer pattern, printing, etc. The ink layer of these methods is separated from the primer, and only exists on the surface of the product without penetrating the primer, which is easily damaged by wear and corrosion. etc. and...
