In the case of the former, a high-level processing technique is required because the surface of the metal agent must be subjected to processing such as grinding and etching for mirror surface processing.

449). This is because the metal plate has a large surface roughness and a mirror-like reflective surface cannot be obtained, so a resin coating film is first applied on the metal body from the meaning of smoothing, and further metal plating is applied to the surface, It is intended to obtain a plated metal body having a mirror-like metallic luster. According to this method, it is possible to obtain the desired designability relatively easily,
The high-gloss appearance, which is close to the mirror surface, complements the decorativeness.

This is performed after the metal base material has been molded into a product shape, and prevents the appearance of defective appearance due to cracking or peeling of the resin film or plating layer during molding. However, since the surface treatment after the molding process is carried out by a batch treatment, it is very inefficient and cannot be produced on a practical scale.

作用を説明する。The present inventors have conducted various studies to give a steel sheet high-gloss designability and formability. As a result, a multi-layer film of chromate treatment layer-resin layer is formed on a steel sheet plated with electric Zn. Further, they have found that the above object can be achieved by forming a chromate-containing resin film and further providing a metal vapor deposition plating layer, and reached the present invention. The operation of each layer will be described below.

きを採用した。(1) Electric Zn-plated steel sheet A steel sheet is excellent in workability and strength and is an inexpensive material. However, since it is inferior in rust preventive property of a cut end face and a scratched portion, it is sacrificed by applying the electric Zn-plated steel sheet. Gives anticorrosion ability. The Zn-based plating method includes electroplating and hot dip plating.
The electroplating has a finer state of the plated crystal and can be uniformly deformed during processing, so that it has an effect that cracks are less likely to occur. Further, in the case of hot dipping, dross easily adheres to the plating surface and is not suitable for use as a substrate for decorative plating, so electric Zn-based plating was used in the present invention.

e, Zn-Ni, and the like. A preferable coating amount is 3 to 30 g / m 2 . Plating coverage is 3g / m 2
If it is less, the necessary minimum sacrificial anticorrosion ability cannot be obtained, and if it is more than 30 g / m 2, cracking of the plating layer during processing tends to occur, which is not preferable.

平滑化効果が小さくなるため好ましくない。(2) Multi-layer coating consisting of chromate-treated layer and resin layer or chromate-containing resin coating In order to obtain a high-gloss plated steel sheet, it is necessary to smooth the substrate. A resin film is provided on the substrate. However, if the resin coating is applied directly on the above-mentioned electric Zn-based plating layer, the adhesiveness is insufficient, so that it peels off during product processing. Therefore, in the present invention,
In addition to applying a resin film, chromating was an essential requirement. The chromate treatment has the effects of improving the rustproof property of the electric Zn-based plating layer and improving the adhesion between the resin film and the Zn-based plating layer. Resin film and Z
A method of performing a phosphate treatment may be considered to improve the adhesion to the n-based plating layer, but the phosphate treatment forms new unevenness on the surface of the plating layer, which results in a smoothing effect of the resin film. Is small, which is not preferable.

得られる。The type of resin constituting the resin film is not particularly limited, and a known phenol type, polyester type, polyamide type, epoxy type, polyurethane type, fluorine type, silicon type, etc., depending on the application, such as one having good heat resistance. Each resin such as the above, or a modified resin thereof can be appropriately selected and used. Further, various modifiers and additives may be added to improve properties such as adhesion, processability and smoothness. Further, this resin film may have a single-layer structure or a multi-layer structure of two layers or three layers or more if necessary. High performance can be achieved by adopting a multi-layer structure in which each layer is responsible for the required characteristics, such as a resin layer with excellent adhesion, a resin layer with excellent workability, and a resin layer with excellent smoothness. A decorative plated steel sheet is obtained.

くるため好ましくない。The thickness of the resin film is preferably 0.5 to 30 μm. If it is less than 0.5 μm, it is difficult to obtain micro glossiness on the plating surface, and it is difficult to obtain high gloss. Further, even if it exceeds 30 μm, the smoothing effect is saturated, and conversely, the risk of film cracking increases as the film thickness increases, which is not preferable.

である。As a method of forming a resin film, a resin solution or a dispersion liquid may be applied to a substrate after chromate treatment in a solvent system or an aqueous system, and a process of film formation, drying and curing may be carried out. If applied and plated with an electroplating line, and subsequently subjected to chromate treatment and resin coating, it is possible to omit the coating line threading.
Further, even if the chromate and the water-based resin solution are mixed, the respective properties and effects are not lost, so that both can be applied in the form of the chromate-containing resin film in a single process.

Since the resin film is an insulating film, examples of the method for plating on the resin film layer include a vapor deposition plating method or an electroless plating method, but a vapor deposition plating method that is relatively easy to perform pretreatment is preferably adopted. It As the vapor deposition plating species, Ag, Al, Cu, Zn, Ni, Cr,

If it is less than 0.02 μm, the thin film is too thin and the underlying layer can be seen through, so a good appearance cannot be provided, and if it exceeds 1 μm, a large stress is generated in the plating layer and cracks in the plating layer and wrinkles in the resin film occur. It is not preferable because it may occur. In addition, the vapor deposition method in the present invention includes various ion plating, sputtering, CVD, etc. in addition to the usual vacuum vapor deposition method.
