Abstract

PURPOSE:To improve the adhesive strength of a paint film to the plating of a plated article by subjecting the article to electrolysis as a cathode in an aqueous soln. contg. sexivalent Cr ions and by coating the article by anionic electrodeposition. CONSTITUTION:A plated metallic or synthetic resin material is subjected to electrolysis as a cathode in an aqueous soln. contg. sexivalent Cr ions as an electrolytic bath to form a colorless transparent chromate film contg. sexivalent Cr on the surface of the plating of the plated material. The chromate film is coated by anionic electrodeposition. Since the chromate film acts as a binder, the adhesive strength of the resulting paint film to the plating is improved.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pretreatment method for improving the adhesion of a coating film when applying anion electrodeposition coating to the surface of a metal-plated article.

Conventionally, metal plating has been widely applied not only to articles made of metals such as iron, copper, brass, cupronickel, zinc, and aluminum, but also to articles made of synthetic resin for anticorrosion, corrosion resistance, or decorative purposes. I came.

However, if the plating metal is nickel or nickel alloy, it will turn black in an extremely short period of time in an atmosphere containing sulfur oxide SO-plated metal, and may lose its luster due to sweat and moisture from the human body. It may change color. If the plating metal is a precious metal such as gold, silver, rhodium, etc.
Although there is no chemical change or discoloration as described above, due to its high price, it is economically difficult to apply thick plating, resulting in an extremely thin plating layer. For this reason, the plating layer often wears out during use, making it impossible to achieve the purpose of plating, such as anticorrosion, as described above. In addition, in terms of appearance, although the metallic luster characteristic of the type of metal used for plating is respected in some cases, it is often the case that a milder metallic luster or other colors are required.

This makes the metal plating layer transparent or semi-transparent.
Alternatively, attempts have been made to paint it with various colors of paint. As such a coating method, a dipping method or a spray method is generally used.

Even with these coating methods, if the outer shape of the plated item to be coated is simple, it is possible to apply the coating relatively uniformly, but if the outer shape is complex,
Even with the spray method, so-called sagging and fogging tend to occur, and it is difficult to obtain a uniform coating film. On top of that,
These methods usually have problems in terms of environmental hygiene due to organic solvents such as thinners in the paint, and the painting process itself requires special skills such as adjusting the viscosity of the paint, and the painting efficiency is low. Moreover, the above-mentioned coating on the surface of a plated article has some fundamental drawbacks. This means that the adhesion between the plating layer and the coating film is poor, and the coating film is likely to peel off. Since the surface of the plating layer that is normally applied to the surface of the product is extremely smooth, it is difficult to mechanically adhere to the coating film. It is known that there is a change over time, which causes poor adhesion with the paint film. Also, in all conventional cases,
Since the plating process and the painting process are necessarily separate and separate processes, oil, dust, etc. contaminate the surface of the plating layer, which also causes poor adhesion.

According to the method of the present invention, after normal metal plating is applied as described above, cathode electrolysis during chromium ion electrolysis is performed in the same jig, without being pulled up and removed from the attachment jig.
Since the surface treatment is performed as a series of steps, including the electrodeposition coating process or baking process, the work process is significantly streamlined. Moreover, since there is no passivation or contamination of the plated metal between the metal plating process and the electrodeposition coating process, the resulting coating film has excellent adhesion.
