Description of the Related Art Metal materials, in particular, galvanized steel sheets, are used in various fields such as automobiles, home appliances and building materials, but have the disadvantage that they corrode in the atmosphere to form a corrosion product called white rust. have. Therefore, in the prior art, for the purpose of improving corrosion resistance, there is a method called chromate treatment in which a coating layer containing hexavalent chromium and trivalent chromium is formed on the surface of a galvanized steel sheet using a treatment solution containing a chromic acid aqueous solution. Generally done.

Wastewater treatment requires special treatment specified in the Water Pollution Control Law. For this reason, in recent years, with an increase in awareness of global environmental conservation, there has been a strong movement to refrain from using compounds harmful to the human body as much as possible.

対応は難しい。On the other hand, as a surface treatment method other than the chromate treatment, a treatment method using a surface treatment agent containing tannic acid is well known. It is considered that when the treatment is performed using an aqueous solution of tannic acid, the protective film formed by the reaction between the tannic acid and the metal material prevents invasion of corrosive substances, so that corrosion resistance is improved. However, with this film, it is difficult to respond to the recent demand for higher quality products (corrosion resistance, paint adhesion).
