理液も種々提案されている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chemical conversion treatment solution used to treat a metal surface such as a galvanized film to form a chemical conversion film with high corrosion resistance and good appearance on the metal surface. After that, chromate treatment is performed to improve the corrosion resistance of this zinc plating, but conventional chromate treatment solutions generally contain hexavalent chromium compounds such as chromic anhydride and potassium dichromate as main components. There is. but,
The chromate treatment solution using this hexavalent chromium compound has the excellent advantage of providing a chromate film with good appearance, gloss, and high corrosion resistance, but hexavalent chromium compounds have moderate problems in terms of pollution prevention. For this reason, it is desired to use a trivalent chromium compound instead of a hexavalent chromium compound, and for this reason, various chromate treatment solutions using trivalent chromium compounds have been proposed.

色調も悪く、耐食性も良くない。However, with the conventional chromate treatment liquid using a trivalent chromium compound, it is difficult to form a chromate film that has a good appearance and high corrosion resistance. for example,
The chromate treatment solution described in JP-A-54-142141 contains trivalent chromium ions, fluoride ions, and acids other than nitric acid. However, the chromate coating formed by this treatment liquid does not have sufficient corrosion resistance. Additionally, the chromate treatment solution described in U.S. Pat. No. 4,222,779 is
Although it contains valent chromium ions, sulfuric acid, hydrogen peroxide, and silicic anhydride, the chromate coating produced by this treatment liquid has a poor color tone and poor corrosion resistance.

をなすに至ったものである。In view of the above circumstances, the present inventors have conducted intensive research into a chemical conversion treatment solution that can impart excellent corrosion resistance to metal surfaces such as galvanized coatings and form a chemical conversion film with a glossy and good color tone. As a result, a chemical conversion treatment solution containing trivalent chromium ions, silicates, fluorides, and acids reliably achieves the above objectives, and when a metal surface is treated with this treatment solution, it has high corrosion resistance. The present inventors have discovered that it is possible to form a chemical conversion film with a glossy appearance and a good appearance, leading to the present invention.
以下、本発明につき更に詳しく説明する。The present invention will be explained in more detail below.

Particularly, for the first time, it has been possible to form a chemical conversion coating with high corrosion resistance and a good appearance. On the other hand, if any one of silicate, heptadide, and acid is missing, a conversion coating with high corrosion resistance and good appearance cannot be obtained.
The object of the present invention cannot be achieved 1. Particularly, when silicate is not contained, the corrosion resistance is not sufficient, and the gloss and color tone are also insufficient. Furthermore, if it does not contain fluoride or acid, it will be glossy.
色調の面で十分でない。The color tone is not good enough.
