【発明の詳細な説明】 （産業上の利用分野） 本発明は表面処理によりステンレス鋼板または酸化着色
ステンレス鋼板の外観を損なうことなく、指紋を付着し
にくくしたステンレス鋼板の製造方法に関する。TECHNICAL FIELD The present invention relates to a method for producing a stainless steel plate in which fingerprints are less likely to adhere without impairing the appearance of the stainless steel plate or the oxidation-colored stainless steel plate by surface treatment.
（従来技術） ステンレス鋼板は、耐久性に優れ、また意匠性にも優れ

かし、ステンレス鋼板の唯一の欠点は、取扱い中に指紋
が付着し易いことである。特に表面仕上げが鏡面（BA）
仕上げのものや表面に酸化皮膜を形成して、その酸化皮
膜の厚さにより赤、緑、青、ゴールドに発色させた着色
ステンレス鋼板などは、付着指紋が目立ち、着色ステン
レス鋼板では指紋の付着した部分が変色して見える。(Prior Art) Since a stainless steel sheet is excellent in durability and design, it has been conventionally used for various purposes. However, the only drawback of the stainless steel plate is that fingerprints tend to adhere during handling. Especially the surface finish is mirror surface (BA)
Fingerprints are conspicuous on colored stainless steel sheets such as finished stainless steel or an oxide film formed on the surface and colored red, green, blue, and gold depending on the thickness of the oxide film, and fingerprints adhered on the colored stainless steel sheet. The part looks discolored.
このため従来指紋が問題になるような用途に使用する場

樹脂、シリコーン樹脂またはフッ素樹脂を皮膜厚が均一
に２μｍ以上になるように直接塗布して、指紋を付着し
にくくしていた。For this reason, when it is used in the conventional application where fingerprints are a problem, a transparent acrylic resin, polyester resin, silicone resin or fluororesin is directly applied to the entire surface so that the film thickness is 2 μm or more. , It made it difficult for fingerprints to adhere.
（発明が解決しようとする問題点） しかしながら、このような樹脂を表面全体に２μｍ以上
塗布すると、皮膜量が多いため、経時変化により発生す
るクラックや樹脂の白化が目立ち、外観を損なうという
問題があった。(Problems to be Solved by the Invention) However, when such a resin is applied to the entire surface in an amount of 2 μm or more, a large amount of film is formed, and thus cracks caused by aging and whitening of the resin are conspicuous, which causes a problem of impairing the appearance. there were.
この問題を回避するには、樹脂皮膜を２μｍ未満にすれ

傾向は、BA仕上げステンレス鋼板や2DR仕上げの酸化着

った。In order to avoid this problem, the resin film should be less than 2 μm, but if the film is thin, interference color is generated by the resin film, and coloring or discoloration occurs. In particular, this tendency was remarkable in the BA finish stainless steel plate and the 2DR finish oxidation-colored stainless steel plate, and in the latter steel plate, the difference in color tone between blue and gold was almost eliminated.
このため、外観を変化させることなく耐指紋性を付与し
たステンレス鋼板が要望されていた。Therefore, there has been a demand for a stainless steel plate having fingerprint resistance without changing the appearance.

ることを見出した。(Means for Solving Problems) The present invention relates to a stainless steel plate by forming a resin discontinuous film having a resin film amount of 0.1 to 2.0 g / m 2 in which a resin is dispersed on the surface of a stainless steel plate or an oxidation-colored stainless steel plate. As a result of investigating the manufacturing method of such a stainless steel sheet based on the knowledge that it is possible to prevent fingerprints from adhering without impairing the appearance by forming an innumerable number of locally exposed portions of the surface of the stainless steel sheet or oxidation. A water-soluble or water-dispersible organic resin emulsion is atomized by an electrostatic atomizer on the surface of a colored stainless steel plate so that the emulsion particles are dispersed on the surface, dried, and the amount of dried resin film is 0.1-2.0 g / It was found that the method of forming a resin discontinuous film of m 2 can be easily manufactured.

連続皮膜を形成したもので、有機樹脂２は不連続である
ため、薄くても干渉色が発生せず、変色の程度も著しく
小さい。また皮膜は薄いため、クラックや白化が発生し
ても目立ちにくい。The stainless steel plate produced by the method of the present invention is formed by forming a discontinuous film in which the organic resin 2 is dispersed on the surface of the stainless steel plate or the oxidation-colored stainless steel plate 1 as shown in the model of FIG. 1 and FIG. Since the organic resin 2 is discontinuous, interference color does not occur even if it is thin, and the degree of discoloration is extremely small. In addition, since the film is thin, it is less noticeable even if cracks or whitening occur.

紋が付着し易く、2.0g/m2を越えると、樹脂が不連続皮

るからである。The amount of resin film is 0.1 to 2.0 g / m 2 in the dry state. This is 0.
If it is less than 1 g / m 2 , there are many unpainted parts, so fingerprints tend to adhere to it, and if it exceeds 2.0 g / m 2 , the resin does not become a discontinuous film and there are problems of interference color, discoloration and cracks. Is caused.

る。The resin film is formed by using a water-soluble or water-dispersible organic resin emulsion, atomizing this emulsion with an electrostatic atomizer, and coating so that the emulsion particles are dispersed on the surface. When an organic resin emulsion is atomized with an electrostatic atomizer, the emulsion becomes fine droplets, so if the same spot is coated for an extremely short time, the entire surface of the stainless steel plate will not be coated, and the uncoated portion will be innumerable. It will remain.
エマルジョンの有機樹脂としては、樹脂単独でもよく、
無機物を含有させた樹脂でもよく、種類に限定はない。The organic resin of the emulsion may be a resin alone,
A resin containing an inorganic substance may be used, and the kind is not limited.
