The present invention relates to a method of forming an iridescent colored hot-dip galvanized coating containing a mixture of the above and the like, and a zinc alloy therefor.

For facilities such as temporary structures for various works and exhibitions, exterior panels, etc., we use colored hot-dip galvanizing, which has a more aesthetically pleasing color that matches the surrounding environment, rather than conventional hot-dip galvanized materials that exhibit a metallic color. It has become a trap so that the material is requested. As aesthetic awareness increases, demand for colored hot-dip galvanized materials is expected to increase in the future in a wide range of fields including architecture, civil engineering, plants, power transmission, transportation, agriculture, fisheries, and more.

着色に用いた塗料の皮膜がメッキ皮膜表面に付着せずに
剥離するに至る欠点がある。The conventional coloring method for hot-dip galvanized rA is to color the plated steel by painting, but since Zn in the plating film of hot-dip galvanized steel is active, the oil component of the paint The fatty acids gradually decompose with alkaline to form zinc soap. Therefore,
There is a drawback that the paint film used for coloring does not adhere to the surface of the plating film and peels off.

多々あった。Therefore, in order to prevent such defects, conventionally, steel is plated with molten zinc, and the plated steel obtained is then exposed to the atmosphere for 1 to 3 weeks to further coat the plated film with Zn(OH). It was necessary to perform the complicated operations of forming corrosion products such as ZnO1ZnCO3 and ZnC1z, then cleaning the surface of the plated steel, and then applying a coating for coloring. Apart from the painting method, a coloring method is known that utilizes the coloring effect of an oxide film during hot-dip galvanizing. For example, Tokuko Sho 46-4200
No. 7 discloses a coloring method using a hot-dip galvanizing bath to which one or more of titanium, manganese, vanadium, etc. is added. However, it was found that the color tone of the colored hot-dip galvanizing obtained according to the technique disclosed herein was generally very pale, the color quickly faded over time, and the coating was likely to peel off. It was not possible to accurately control the color development of the desired color, and the tones often became blurred.

飾性が今後重要視されるものと思われる。Under these circumstances, the applicant of the present application has worked to establish a colored hot-dip galvanizing technology that produces vivid colors by increasing the amount of additives, and has achieved many results. Nowadays, it is possible to freely produce a wide variety of hues such as golden yellow, purple, blue, yellow, dark red, and green by combining component control and plating and post-processing conditions. If the conventional hue can be made richer and the aesthetics and decoration, as well as the artistry, can be further improved, the scope of colored hot-dip galvanizing will be further expanded. For example, various exhibition halls,
Highly decorative materials would be appropriate for temporary pedestals and exterior panels at amusement parks. It is thought that decorativeness will become important in the future for guardrails and civil engineering and construction sites around the city.

Examples include the purest zinc ingot (9999% purity) and special zinc ingot.The impurities unavoidably contained in these zinc ingots are, for example, Pbt2vt% in one type of distilled zinc ingot.
Hereinafter, Cd (L1vt% or less, F@CLO20wt% or less), but in the present invention, it is preferable to use a zinc base metal in which the total content of these impurities is less than t5vt%.
