本発明は、意匠性に優れた塗装エンボスステンレス鋼板およびその製造方法に関する。 The present invention relates to a coated embossed stainless steel plate excellent in design and a method for producing the same.
塗装鋼板は、家電製品の外板などに高い割合で採用されている。近年、家電製品に要求される意匠は、より多様化および高度化しており、塗装鋼板に求められる意匠も、より多様化および高度化している。 Pre-painted steel sheets are used at a high rate in the outer panels of home appliances. In recent years, designs required for home appliances have become more diversified and sophisticated, and designs required for coated steel sheets have also become more diversified and sophisticated.
塗装鋼板の意匠性を高める手段の一つとして、エンボス鋼板を塗装原板として使用することが考えられる。塗装エンボス鋼板は、家電製品だけではなく、キッチン部材や外装建材などでも採用されている。 As one of means for improving the design of the coated steel sheet, it is conceivable to use an embossed steel sheet as a coating original sheet. Painted embossed steel sheets are used not only for home appliances but also for kitchen materials and exterior building materials.
また、塗装鋼板の意匠性をさらに高める手段の一つとして、エンボス加工を施した鋼板（以下「エンボス鋼板」という）の凸部または凹部のみを塗装することが提案されている（例えば、特許文献１〜３参照）。特許文献１，２には、エンボス鋼板の凸部にのみ有色塗膜を形成する塗装エンボス鋼板の製造方法が開示されている。一方、特許文献３には、エンボス鋼板の凹部にのみ有色塗膜を形成する塗装エンボス鋼板の製造方法が開示されている。特許文献３の塗装エンボス鋼板の製造方法では、凸部を形成する凸ロールおよび凹部を形成する凹ロールを用いてエンボス加工する際に、凹ロールの凸部の頂面に予め塗料を付着させておくことで、エンボス加工と凹部への塗装を同時に行っている。 In addition, as one of the means for further improving the design of the coated steel sheet, it has been proposed to coat only convex portions or concave portions of an embossed steel plate (hereinafter referred to as “embossed steel plate”) (for example, Patent Documents). 1-3). Patent Documents 1 and 2 disclose a method for producing a coated embossed steel sheet in which a colored coating film is formed only on the convex portion of the embossed steel sheet. On the other hand, Patent Document 3 discloses a method for producing a coated embossed steel sheet in which a colored coating film is formed only on the concave portion of the embossed steel sheet. In the manufacturing method of the coating embossed steel plate of patent document 3, when embossing using the convex roll which forms a convex part, and the concave roll which forms a recessed part, a coating material is made to adhere to the top face of the convex part of a concave roll beforehand. By doing so, embossing and coating on the recesses are performed simultaneously.
このように、エンボス鋼板の凸部または凹部のみを塗装することで、意匠性に優れるツートーンカラーの塗装エンボス鋼板を製造することができる。 Thus, by coating only the convex portion or the concave portion of the embossed steel sheet, a two-tone colored embossed steel sheet having excellent design can be manufactured.
ツートーンカラーの塗装エンボス鋼板を製造する際に、エンボス鋼板の凸部だけに有色塗膜を形成した塗装エンボス鋼板は、使用時に最も傷付きやすい凸部の頂面に有色塗膜が形成されているため、使用時に有色塗膜が剥離して意匠が変化しやすいという問題がある。したがって、使用時の傷付きによる意匠の変化を防ぐという観点からは、エンボス鋼板の凸部のみに有色塗膜を形成した塗装エンボス鋼板よりも、エンボス鋼板の凹部のみに有色塗膜を形成した塗装エンボス鋼板の方が好ましい。 When producing a two-tone painted embossed steel sheet, a colored embossed steel sheet with a colored coating film formed only on the convex part of the embossed steel sheet has a colored coating film formed on the top surface of the convex part that is most likely to be damaged during use. Therefore, there is a problem that the colored coating film peels off during use and the design is likely to change. Therefore, from the viewpoint of preventing changes in the design due to scratches during use, coating with a colored coating film only on the recessed portion of the embossed steel sheet, rather than a coated embossed steel sheet with a colored coating film formed only on the convex portion of the embossed steel sheet An embossed steel sheet is preferred.
前述の通り、エンボス鋼板の凹部のみに有色塗膜を形成する塗装エンボス鋼板の製造方法としては、特許文献３に開示されている方法がある。しかしながら、特許文献３に記載の製造方法は、主に金属サイディングを対象としたものであり、家電製品やキッチン部材で好まれる微細な凹凸パターンの塗装エンボス鋼板を製造する場合に、凸部と凹部とを高精度で塗り分けることができない。 As described above, there is a method disclosed in Patent Document 3 as a manufacturing method of a coated embossed steel plate in which a colored coating film is formed only on the concave portion of the embossed steel plate. However, the manufacturing method described in Patent Document 3 is mainly intended for metal siding, and when manufacturing a coated embossed steel sheet having a fine uneven pattern that is preferred for home appliances and kitchen parts, a convex portion and a concave portion are used. Cannot be painted with high accuracy.
特許文献３に記載の塗装エンボス鋼板の製造方法では、凹ロールの凸部（塗料が付着している）を鋼板に強く押し付けるため、凹ロールの凸部と鋼板との間に存在するインクが横に漏れることがある。特許文献３に記載されているような大きな凹凸パターンの塗装エンボス鋼板（例えば、レンガタイル調の外装建材）では、インクの横漏れが発生しても外観上大きな問題とはならないかもしれない。しかしながら、微細な凹凸パターンの塗装エンボス鋼板では、インクの横漏れが発生してしまうと、凸部の頂面にも塗料が付着して意匠性が顕著に低下してしまうおそれがある。 In the method for producing a coated embossed steel sheet described in Patent Document 3, the convex portion of the concave roll (with the paint attached) is strongly pressed against the steel plate, so that the ink existing between the convex portion of the concave roll and the steel plate is laterally distributed. May leak. In a coated embossed steel sheet having a large uneven pattern as described in Patent Document 3 (for example, a brick tile-like exterior building material), even if side leakage of ink occurs, it may not be a big problem in appearance. However, in a coated embossed steel sheet with a fine uneven pattern, if a lateral leakage of ink occurs, the paint may adhere to the top surface of the convex portion, and the design may be significantly reduced.
本発明は、かかる点に鑑みてなされたものであり、微細な凹凸パターンのエンボス鋼板を塗装原板とした場合であっても凸部の頂面とそれ以外の領域（凸部の側面および凹部間の領域）とを高精度で塗り分けることができる、塗装エンボス鋼板の製造方法を提供することを目的とする。 The present invention has been made in view of the above points, and even when an embossed steel plate having a fine uneven pattern is used as a coating original plate, the top surface of the convex portion and other regions (between the side surface of the convex portion and the concave portion). It is an object of the present invention to provide a method for producing a coated embossed steel sheet that can be applied with high accuracy.
また、本発明は、エンボス鋼板の凸部の頂面以外の領域にのみ塗膜を有する塗装エンボス鋼板であって、凸部の頂面とそれ以外の領域とが高精度で塗り分けられた塗装エンボス鋼板を提供することを目的とする。 Further, the present invention is a coated embossed steel sheet having a coating film only in a region other than the top surface of the convex portion of the embossed steel plate, and the top surface of the convex portion and the other region are coated with high accuracy. An object is to provide an embossed steel sheet.
本発明者は、エンボス鋼板の表面に塗料を塗布した後に凸部の頂面上の塗料または塗膜を除去することで、微細な凹凸パターンのエンボス鋼板を塗装原板とした場合であっても凸部の頂面とそれ以外の領域とが高精度に塗り分けられた塗装エンボス鋼板を製造できることを見出し、さらに検討を加えて本発明を完成させた。 The present inventor removes the paint or coating film on the top surface of the convex portion after applying the paint to the surface of the embossed steel plate, so that even if the embossed steel plate having a fine uneven pattern is used as a coating original plate, The present inventors have found that it is possible to produce a coated embossed steel sheet in which the top surface of the part and the other region are separately coated with high accuracy, and have further studied and completed the present invention.

1. Painted Embossed Stainless Steel Plate The painted embossed stainless steel plate of the present invention has a stainless steel plate (painted original plate) that has been embossed and a colored coating film formed on the surface of the stainless steel plate. The coated embossed stainless steel plate of the present invention is characterized in that the top surface of the convex portion of the embossed stainless steel plate is not covered with a colored coating film.
以下、本発明の塗装エンボスステンレス鋼板の各構成要素について説明する。 Hereinafter, each component of the coated embossed stainless steel plate of the present invention will be described.
［塗装原板］
塗装原板としては、表面に複数の微細な凸部を形成するエンボス加工が施されたステンレス鋼板（以下「エンボスステンレス鋼板」という）が使用される。以下、エンボスステンレス鋼板の表面のうち、凸部が形成されていない領域（凸部間の領域）を「凹部」ということがある。
[Painted original plate]
As the coating original plate, a stainless steel plate (hereinafter referred to as “embossed stainless steel plate”) that is embossed to form a plurality of fine convex portions on the surface is used. Hereinafter, the area | region (area | region between convex parts) in which the convex part is not formed among the surfaces of an embossed stainless steel plate may be called "concave part."
エンボス加工が施されるステンレス鋼板の鋼種や表面仕上げの種類、硬さなどは、特に限定されない。ステンレス鋼板の鋼種の例には、ＳＵＳ３０４、ＳＵＳ４３０、ＳＵＳ３１６などが含まれる。また、ステンレス鋼板の表面仕上げの種類の例には、ＢＡ、２Ｂ、２Ｄ、Ｎｏ.４、ＨＬなどが含まれる。 There are no particular limitations on the steel type, surface finish type, hardness, etc. of the stainless steel plate to be embossed. Examples of the steel type of the stainless steel plate include SUS304, SUS430, and SUS316. Examples of types of surface finishing of stainless steel plates include BA, 2B, 2D, No. 4, HL, and the like.
ステンレス鋼板に施されるエンボス加工の凹凸パターン（凸部の形状および配置）は、特に限定されず、用途に応じて適宜選択されうる。凹凸パターンの例には、水玉（円）柄、多角形柄、不規則柄などが含まれる。凹凸パターンの種類に関わらず、凸部は頂面（上面）および側面を有する。たとえば、凹凸パターンが水玉柄の場合は、凸部の形状は略円柱状または略円錐台状である。後述する本発明の製造方法で本発明の塗装エンボスステンレス鋼板を製造する場合、凸部の頂面は平面であることが多い。また、複数の凸部の頂面は同一平面上に位置することが多い。すなわち、凸部の高さは同一であることが多い。なお、「凸部の頂面が平面である」とは、凸部の頂面が曲面ではないということを意味しており、平滑であることを意味しているわけではない。すなわち、凸部の頂面は、平滑であってももちろんよいが、完全に平滑でなくてもよい。たとえば、凸部の頂面には、ヘアーラインなどの研磨模様が付されていてもよい。 The embossed concavo-convex pattern (the shape and arrangement of the convex portions) applied to the stainless steel plate is not particularly limited and may be appropriately selected depending on the application. Examples of the uneven pattern include a polka dot (circle) pattern, a polygonal pattern, and an irregular pattern. Regardless of the type of concavo-convex pattern, the convex portion has a top surface (upper surface) and side surfaces. For example, when the concavo-convex pattern is a polka dot pattern, the shape of the convex portion is a substantially cylindrical shape or a substantially truncated cone shape. When the coated embossed stainless steel plate of the present invention is manufactured by the manufacturing method of the present invention described later, the top surface of the convex portion is often a flat surface. In addition, the top surfaces of the plurality of convex portions are often located on the same plane. That is, the height of the convex portion is often the same. Note that “the top surface of the convex portion is a flat surface” means that the top surface of the convex portion is not a curved surface, and does not mean that it is smooth. That is, the top surface of the convex portion may be smooth or may not be completely smooth. For example, a polishing pattern such as a hairline may be provided on the top surface of the convex portion.
後述する本発明の製造方法で製造することで、微細な凹凸パターンのエンボスステンレス鋼板を塗装原板としても、凸部と凹部とが高精度で塗り分けられた本発明の塗装エンボスステンレス鋼板を製造することができる。たとえば、エンボスステンレス鋼板を平面視したときの凸部の頂面の最大径が１００μｍ〜３０ｍｍの範囲内であり、かつ凸部の頂面間の間隔が１００μｍ〜３０ｍｍの範囲内であっても、凸部と凹部とが高精度で塗り分けられている。ここで「凸部の頂面の最大径」とは、例えば、平面視したときの凸部の頂面の形状が円形の場合は直径を意味し、平面視したときの凸部の頂面の形状が長方形の場合は対角線の長さを意味する。 By producing the embossed stainless steel plate having a fine uneven pattern by using the production method of the present invention to be described later, the coated embossed stainless steel plate of the present invention in which the convex portions and the concave portions are separately coated with high accuracy is produced. be able to. For example, even when the maximum diameter of the top surface of the convex portion when the embossed stainless steel plate is viewed in plan is in the range of 100 μm to 30 mm, and the interval between the top surfaces of the convex portions is in the range of 100 μm to 30 mm, The convex portion and the concave portion are separately painted with high accuracy. Here, the “maximum diameter of the top surface of the convex portion” means, for example, the diameter when the shape of the top surface of the convex portion when viewed in plan is circular, and the top surface of the convex portion when viewed in plan. When the shape is rectangular, it means the length of the diagonal line.
凸部の高さは、特に限定されず、目的に応じて適宜設定されうる。たとえば、意匠性の付与のみを意図する場合は、凸部の高さを５〜１００μｍの範囲内とすればよい。凸部の高さを５μｍ以上とすることで、凸部と凹部との塗り分けを容易にすることができる。また、意匠性の付与に加えて耐滑性などの機能も付与する場合は、例えば凸部の高さを１００μｍより高くすればよい。 The height of the convex portion is not particularly limited, and can be set as appropriate according to the purpose. For example, when only the designability is intended, the height of the convex portion may be in the range of 5 to 100 μm. By setting the height of the convex portion to 5 μm or more, it is possible to easily separate the convex portion and the concave portion. Moreover, what is necessary is just to make height of a convex part higher than 100 micrometers, for example, when providing functions, such as slip resistance, in addition to provision of designability.
塗装原板となるエンボスステンレス鋼板は、耐食性および塗膜密着性を向上させる観点から、化成処理皮膜を形成されていてもよい。この場合、化成処理の種類は特に限定されない。化成処理の例には、クロメート処理、クロムフリー処理、リン酸塩処理などが含まれる。化成処理皮膜は、エンボスステンレス鋼板の表面全体に形成されていてもよいし、有色塗膜で被覆される領域にのみ形成されていてもよい。 From the viewpoint of improving the corrosion resistance and the adhesion of the coating film, the embossed stainless steel plate as the coating original plate may be formed with a chemical conversion treatment film. In this case, the type of chemical conversion treatment is not particularly limited. Examples of the chemical conversion treatment include chromate treatment, chromium-free treatment, phosphate treatment and the like. The chemical conversion treatment film may be formed on the entire surface of the embossed stainless steel plate, or may be formed only in the region covered with the colored coating film.
化成処理皮膜の膜厚は、エンボスステンレス鋼板の腐食の抑制および塗膜密着性の向上に有効な範囲内であれば特に限定されない。たとえば、クロメート皮膜の場合、全Ｃｒ換算付着量が５〜１００ｍｇ／ｍ２となるように膜厚を調整すればよい。また、クロムフリー皮膜の場合、Ｔｉ−Ｍｏ複合皮膜では１０〜５００ｍｇ／ｍ２、フルオロアシッド系皮膜ではフッ素換算付着量または総金属元素換算付着量が３〜１００ｍｇ／ｍ２の範囲内となるように膜厚を調整すればよい。また、リン酸塩皮膜の場合、付着量が５〜５００ｍｇ／ｍ２となるように膜厚を調整すればよい。 The film thickness of the chemical conversion coating is not particularly limited as long as it is within a range effective for inhibiting corrosion of the embossed stainless steel plate and improving coating film adhesion. For example, in the case of a chromate film, the film thickness may be adjusted so that the total Cr equivalent adhesion amount is 5 to 100 mg / m 2 . Further, in the case of a chromium-free coating, the Ti-Mo composite coating has a range of 10 to 500 mg / m 2 , and the fluoroacid-based coating has a fluorine equivalent or total metal element equivalent deposit of 3 to 100 mg / m 2. The film thickness may be adjusted. In the case of a phosphate film, the film thickness may be adjusted so that the adhesion amount is 5 to 500 mg / m 2 .
［有色塗膜］
有色塗膜は、有機樹脂を主成分とする、着色顔料が配合された塗膜である。有色塗膜は、１層構成であってもよいし、下塗り（プライマー）塗膜および上塗り（トップ）塗膜の２層構成であってもよいし、３層以上の構成であってもよい。
[Colored coating]
The colored coating film is a coating film containing an organic resin as a main component and blended with a color pigment. The colored coating may have a one-layer configuration, a two-layer configuration of an undercoat (primer) coating and a top coat (top) coating, or a configuration of three or more layers.
有色塗膜は、エンボスステンレス鋼板の凸部の側面（頂面以外の面）および凹部（平坦面）を被覆しているが、凸部の頂面は被覆していない。したがって、本発明の塗装エンボスステンレス鋼板は、凸部の頂面ではステンレス鋼の色調を呈し、それ以外の領域（凸部の側面および凹部）では有色塗膜の色調を呈する。その結果、本発明の塗装エンボスステンレス鋼板は、ツートーンカラーの外観を呈する。なお、有色塗膜は、下地を完全に隠蔽している必要はなく、カラークリア塗膜であってもよい。 The colored coating coats the side surface (surface other than the top surface) and the concave portion (flat surface) of the convex portion of the embossed stainless steel plate, but does not cover the top surface of the convex portion. Therefore, the coated embossed stainless steel plate of the present invention exhibits the color tone of stainless steel on the top surface of the convex portion, and the color tone of the colored coating film in other regions (side surfaces and concave portions of the convex portion). As a result, the coated embossed stainless steel sheet of the present invention exhibits a two-tone color appearance. In addition, the colored coating film does not need to completely hide the base, and may be a color clear coating film.
なお、本発明の塗装エンボスステンレス鋼板は、少なくとも、凹部だけでなく凸部の側面も有色塗膜で被覆されている点で特許文献３に記載の塗装エンボス鋼板と異なる。 The coated embossed stainless steel plate of the present invention differs from the coated embossed steel plate described in Patent Document 3 in that at least not only the concave portions but also the side surfaces of the convex portions are covered with the colored coating film.
意匠性の観点からは、凸部の頂面とそれ以外の領域（有色塗膜）との間の色差ΔＥは、１以上が好ましく、２以上がより好ましい。色差ΔＥが１未満の場合、目視では色調の違いを判別することが困難であり、凸部の頂面の有色塗膜を除去することによる意匠性の向上効果が十分ではない。たとえば、ΔＥを２〜１０程度とすることで、ステンレス鋼と同系色での繊細な色調の違いを表現することができる。また、ΔＥを１０以上とすることで、明確なツートーンカラーの外観を呈するインパクトのある意匠を得られる。なお、本明細書において「色差」とは、ＣＩＥＬＡＢ色差式により算出される値であり、ＪＩＳ Ｋ５６００−４−４、ＪＩＳ Ｋ５６００−４−５およびＪＩＳ Ｋ５６００−４−６に規定されている測色の原理、測色方法および色差の算出方法に準拠するものである。 From the viewpoint of design properties, the color difference ΔE between the top surface of the convex portion and the other region (colored coating film) is preferably 1 or more, and more preferably 2 or more. When the color difference ΔE is less than 1, it is difficult to visually distinguish the difference in color tone, and the effect of improving the design property by removing the colored coating film on the top surface of the convex portion is not sufficient. For example, by setting ΔE to about 2 to 10, it is possible to express a delicate color tone difference in the same color as stainless steel. Further, by setting ΔE to 10 or more, it is possible to obtain an impact design that exhibits a clear two-tone color appearance. In this specification, “color difference” is a value calculated by the CIELAB color difference formula, and colorimetry specified in JIS K5600-4-4, JIS K5600-4-5 and JIS K5600-4-6. And the color measurement method and the color difference calculation method.
凸部の頂面（ステンレス鋼の色調）とそれ以外の領域（有色塗膜の色調）との色差ΔＥは、市販の測色計を用いて測定することができる。エンボスステンレス鋼板の凹凸パターンによっては、測色計の最小測色面積内に凸部と凹部の両方が含まれてしまい、凸部の頂面とそれ以外の領域とを区別して測色することができないことがある。このような場合は、凸部の頂面と同視しうる未塗装のステンレス鋼板、およびそれ以外の領域と同視しうる塗装ステンレス鋼板の測色結果を用いて色差を求めればよい。すなわち、凸部の頂面を測色する代わりに、同じ鋼種で同じ表面状態のステンレス鋼板（エンボス加工が施されていない）の表面を測色する。同様に、凹部の有色塗膜を測色する代わりに、この有色塗膜と同じ塗膜を前記ステンレス鋼板の表面に形成し、形成された有色塗膜を測色する。これらの測定結果から色差を算出することで、凸部の頂面とそれ以外の領域（有色塗膜）との色差ΔＥを求めることができる。 The color difference ΔE between the top surface of the convex portion (stainless steel color tone) and the other region (colored coating color tone) can be measured using a commercially available colorimeter. Depending on the concavo-convex pattern of the embossed stainless steel plate, both the convex part and the concave part are included within the minimum colorimetric area of the colorimeter, and it is possible to perform colorimetry by distinguishing the top surface of the convex part and other areas. There are things that cannot be done. In such a case, the color difference may be obtained using the colorimetric results of an unpainted stainless steel plate that can be equated with the top surface of the convex portion and a coated stainless steel plate that can be equated with other regions. That is, instead of measuring the top surface of the convex portion, the surface of a stainless steel plate (not embossed) with the same steel type and the same surface state is measured. Similarly, instead of measuring the color coating film of the concave portion, the same coating film as this color coating film is formed on the surface of the stainless steel plate, and the formed color coating film is measured. By calculating the color difference from these measurement results, the color difference ΔE between the top surface of the convex portion and the other region (colored coating film) can be obtained.
主成分となる有機樹脂の種類は、特に限定されず、製造方法（プレコート方式またはポストコート方式）や用途などに応じて適宜選択されうる。たとえば、プレコート方式で有色塗膜を形成する場合、使用しうる樹脂の例には、ポリエステル樹脂、アルキド樹脂、アクリル樹脂、アクリル−スチレン樹脂、スチレン樹脂、シリコーン樹脂、エポキシ樹脂、フェノール樹脂、フッ素樹脂、尿素樹脂、メラミン樹脂もしくはベンゾグアナミン樹脂、およびこれらの樹脂をウレタン変性、シリコーン変性もしくはエポキシ変性した樹脂が含まれる。また、ポストコート方式で有色塗膜を形成する場合、使用しうる樹脂の例には、上述の樹脂に加え、プレコート化が困難とされているポリアミドイミド樹脂や、粉体塗装であれば塗装できる塗料化が困難なポリオレフィン樹脂などが含まれる。これらの樹脂は、単独で使用してもよいし、２種以上を組み合わせて使用してもよい。 The kind of organic resin used as a main component is not specifically limited, According to a manufacturing method (a precoat system or a postcoat system), a use, etc., it can select suitably. For example, when forming a colored coating film by the precoat method, examples of resins that can be used include polyester resin, alkyd resin, acrylic resin, acrylic-styrene resin, styrene resin, silicone resin, epoxy resin, phenol resin, fluororesin , Urea resins, melamine resins or benzoguanamine resins, and resins obtained by urethane modification, silicone modification or epoxy modification of these resins. In addition, in the case of forming a colored coating film by the post-coating method, examples of resins that can be used include polyamide imide resins that are difficult to pre-coat in addition to the above-mentioned resins, and can be painted by powder coating. This includes polyolefin resins that are difficult to paint. These resins may be used alone or in combination of two or more.
有色塗膜を着色する着色顔料の種類は、エンボスステンレス鋼板を構成するステンレス鋼と有色塗膜との間で所望の色差を得ることができれば特に限定されない。着色顔料の例には、酸化チタン、カーボンブラック、酸化クロム、酸化鉄、ベンガラ、チタンイエロー、コバルトブルー、コバルトグリーン、アニリンブラック、フタロシアニンブルーなどが含まれる。また、有色塗膜には、パール顔料や、アルミやステンレス、ニッケルなどの金属粉からなるメタリック顔料などが配合されていてもよい。 The type of the color pigment that colors the colored coating film is not particularly limited as long as a desired color difference can be obtained between the stainless steel constituting the embossed stainless steel plate and the colored coating film. Examples of the color pigment include titanium oxide, carbon black, chromium oxide, iron oxide, bengara, titanium yellow, cobalt blue, cobalt green, aniline black, phthalocyanine blue and the like. Further, the colored coating film may contain a pearl pigment, a metallic pigment made of metal powder such as aluminum, stainless steel, nickel, or the like.
有色塗膜には、耐食性を向上させる観点から、防錆顔料が配合されていてもよい。防錆顔料の例には、リン酸亜鉛、亜リン酸亜鉛、リン酸亜鉛マグネシウム、リン酸マグネシウム、亜リン酸マグネシウム、シリカ、カルシウムイオン交換シリカ、リン酸ジルコニウム、トリポリリン酸２水素アルミニウム、酸化亜鉛、リンモリブデン酸亜鉛、メタホウ酸バリウムなどが含まれる。また、有色塗膜には、体質顔料が配合されていてもよい。体質顔料の例には、硫酸バリウム、酸化チタン、シリカ、炭酸カルシウムなどが含まれる。 The colored coating film may be blended with a rust preventive pigment from the viewpoint of improving the corrosion resistance. Examples of rust preventive pigments include zinc phosphate, zinc phosphite, magnesium magnesium phosphate, magnesium phosphate, magnesium phosphite, silica, calcium ion exchanged silica, zirconium phosphate, aluminum trihydrogen phosphate, zinc oxide , Zinc phosphomolybdate, barium metaborate and the like. An extender pigment may be blended in the colored coating film. Examples of extender pigments include barium sulfate, titanium oxide, silica, calcium carbonate and the like.
さらに、有色塗膜には、塗膜硬度および耐摩耗性を向上させる観点または塗膜表面に凹凸を付与し外観を向上させる観点から、鱗片状無機質添加材や無機質繊維、粒状または塊状の有機骨材、粒状または塊状の無機骨材、つや消し剤などが配合されていてもよい。鱗片状無機質添加材の例には、ガラスフレーク、硫酸バリウムフレーク、グラファイトフレーク、合成マイカフレーク、合成アルミナフレーク、シリカフレーク、雲母状酸化鉄（ＭＩＯ）などが含まれる。無機質繊維の例には、チタン酸カリウム繊維、ウォラスナイト繊維、炭化ケイ素繊維、アルミナ繊維、アルミナシリケート繊維、シリカ繊維、ロックウール、スラグウール、ガラス繊維、炭素繊維などが含まれる。有機骨材の例には、アクリルビーズ、ポリアクリロニトリル（ＰＡＮ）ビーズなどが含まれる。無機骨材、つや消し剤の例には、ガラスビース、シリカ粉などが含まれる。 Furthermore, from the viewpoint of improving the coating film hardness and abrasion resistance, or imparting irregularities to the surface of the coating film to improve the appearance, the colored coating film has a scaly inorganic additive, inorganic fiber, granular or massive organic bone. Materials, granular or massive inorganic aggregates, matting agents and the like may be blended.

Examples of organic aggregates include acrylic beads, polyacrylonitrile (PAN) beads, and the like. Examples of inorganic aggregates and matting agents include glass beads and silica powder.
有色塗膜の膜厚は、特に限定されないが、意匠性の観点からは、凹部（平坦部）における膜厚が３μｍ以上であることが好ましい。凹部の膜厚を３μｍ以上とすることで、凸部の頂面とそれ以外の領域との色差ΔＥを１以上とすることができる。また、カラークリア塗膜以外の透明性の低い有色塗膜を形成する場合に、工業製品として安定的な下地隠蔽性を実現することができる。一方、製造性の観点からは、凹部の膜厚はエンボスステンレス鋼板の凸部の高さ未満であることが好ましい。凹部の膜厚が凸部の高さ以上の場合、製造時に凸部の頂面の塗料または塗膜を除去することが困難である。また、プレコート方式で塗料を焼き付けて塗膜を形成する場合は、凹部の１層ごとの膜厚は、凸部の高さ未満であることに加えて、さらに３０μｍ以下であることが好ましい。１層の膜厚が３０μｍを超える場合、塗料を焼き付ける際にワキと称される外観不良が生じやすいからである。 Although the film thickness of a colored coating film is not specifically limited, From the viewpoint of designability, it is preferable that the film thickness in a recessed part (flat part) is 3 micrometers or more. By setting the film thickness of the concave portion to 3 μm or more, the color difference ΔE between the top surface of the convex portion and the other region can be set to 1 or more. Moreover, when forming a colored coating film with low transparency other than a color clear coating film, a stable base concealing property as an industrial product can be realized. On the other hand, from the viewpoint of manufacturability, the film thickness of the recess is preferably less than the height of the protrusion of the embossed stainless steel plate. When the film thickness of the concave portion is equal to or higher than the height of the convex portion, it is difficult to remove the paint or coating film on the top surface of the convex portion at the time of production. Moreover, when baking a coating material and forming a coating film by a precoat system, it is preferable that the film thickness for every layer of a recessed part is 30 micrometers or less in addition to being less than the height of a convex part. This is because, when the film thickness of one layer exceeds 30 μm, an appearance defect called “Waki” tends to occur when the paint is baked.
以上のように、本発明の塗装エンボス鋼板ステンレス鋼板は、凸部の頂面ではステンレス鋼の色調を呈し、それ以外の領域（凸部の側面および凹部）では有色塗膜の色調を呈するため、一般的な塗装エンボスステンレス鋼板にはないインパクトのある外観を呈する。特に、本発明の塗装エンボス鋼板ステンレス鋼板は、凸部の頂面とそれ以外の領域とが高精度に塗り分けられているため、意匠性に優れている。 As described above, the coated embossed steel plate stainless steel plate of the present invention exhibits the color tone of stainless steel on the top surface of the convex portion, and exhibits the color tone of the colored coating film in other regions (side surfaces and concave portions of the convex portion). It has an impact appearance that is not found in typical painted embossed stainless steel sheets. Particularly, the coated embossed steel plate stainless steel plate of the present invention is excellent in design because the top surface of the convex portion and the other region are separately coated with high accuracy.
本発明の塗装エンボスステンレス鋼板は、使用時に最も傷付きやすい凸部の頂面に有色塗膜が形成されていないため、凸部の頂面に物が接触しても塗膜剥離による意匠の変化は生じない。また、本発明の塗装エンボスステンレス鋼板は、凸部の頂面以外の領域が有色塗膜で被覆されているため、耐汚染性や汚れ拭取り性に優れた塗膜を形成すれば、エンボスステンレス鋼板の使用時に問題となりやすい凹部に溜まった汚れを除去しやすい。 The coated embossed stainless steel sheet of the present invention does not have a colored coating film on the top surface of the convex portion that is most likely to be damaged during use. Does not occur. In addition, since the coated embossed stainless steel sheet of the present invention is coated with a colored coating on the region other than the top surface of the convex portion, the embossed stainless steel plate can be formed by forming a coating excellent in stain resistance and dirt wiping. It is easy to remove the dirt accumulated in the recesses, which can be a problem when using steel sheets.
なお、本発明の塗装エンボスステンレス鋼板では、凸部の頂面が有色塗膜で被覆されていなければよく、凸部の頂面においてステンレス鋼が外部に露出している必要はない。たとえば、凸部の頂面は、クリア塗膜や化成処理皮膜などの色調の付与に寄与しない塗膜または皮膜で被覆されていてもよい。もちろん、ステンレス鋼は耐食性に優れているので、凸部の頂面においてステンレス鋼が外部に露出していてもよい。 In the coated embossed stainless steel plate of the present invention, the top surface of the convex portion may not be covered with a colored coating film, and the stainless steel need not be exposed to the outside on the top surface of the convex portion. For example, the top surface of the convex portion may be covered with a coating film or film that does not contribute to imparting color tone, such as a clear coating film or a chemical conversion treatment film. Of course, since stainless steel is excellent in corrosion resistance, the stainless steel may be exposed to the outside on the top surface of the convex portion.
本発明の塗装エンボスステンレス鋼板は、次に説明する本発明の製造方法により製造されうる。 The coated embossed stainless steel sheet of the present invention can be manufactured by the manufacturing method of the present invention described below.

2. Manufacturing method of coated embossed stainless steel plate The manufacturing method of the coated embossed stainless steel plate according to the present invention includes: 1) a first step of preparing an embossed stainless steel plate (painted original plate); and 2) applying a colored paint to the surface of the embossed stainless steel plate. A second step, and 3) a third step of removing the colored paint or the colored coating film on the top surface of the convex portion of the embossed stainless steel plate.
第３のステップにおいて凸部の頂面の有色塗膜を除去する場合は、第２のステップと第３のステップの間に第２のステップで塗布した有色塗料を焼き付ける（または硬化させる）。一方、第３のステップにおいて凸部の頂面の有色塗料を除去する場合は、第３のステップの後に鋼板表面に残っている有色塗料を焼き付ける（または硬化させる）。 When removing the colored coating film on the top surface of the convex portion in the third step, the colored paint applied in the second step is baked (or cured) between the second step and the third step. On the other hand, when the colored paint on the top surface of the convex portion is removed in the third step, the colored paint remaining on the steel sheet surface is baked (or cured) after the third step.
以下、本発明の製造方法の各ステップについて説明する。 Hereinafter, each step of the manufacturing method of the present invention will be described.
１）第１のステップ
第１のステップでは、塗装原板を準備する。前述の通り、塗装原板としては、表面に複数の微細な凸部を形成するエンボス加工が施されたステンレス鋼板（エンボスステンレス鋼板）が使用される。エンボスステンレス鋼板は、例えば、外周部に所定の凹部パターンを有する圧延ローラーを用いてステンレス鋼板を圧延することで製造されうる。
1) First Step In the first step, a coating original plate is prepared. As described above, a stainless steel plate (embossed stainless steel plate) that is embossed to form a plurality of fine convex portions on the surface is used as the coating original plate. An embossed stainless steel plate can be manufactured, for example, by rolling a stainless steel plate using a rolling roller having a predetermined concave pattern on the outer periphery.
エンボスステンレス鋼板の凸部の頂面は平面であることが好ましい。また、複数の凸部の頂面は、同一平面状に位置することが好ましい。第３のステップにおいて、凸部の頂面上の有色塗料または有色塗膜をより容易かつよりきれいに除去するためである。また、第２のステップにおいてロールコート法で有色塗料を塗布する場合は、ロール寿命の観点からも凸部の頂面は平面であることが好ましい。 The top surface of the convex portion of the embossed stainless steel plate is preferably a flat surface. Moreover, it is preferable that the top surfaces of the plurality of convex portions are located on the same plane. This is because, in the third step, the colored paint or the colored coating film on the top surface of the convex portion is more easily and cleanly removed. Moreover, when applying a colored paint by a roll coat method in a 2nd step, it is preferable that the top surface of a convex part is a plane also from a viewpoint of roll lifetime.
前述の通り、塗装原板となるエンボスステンレス鋼板は、化成処理皮膜を形成されていてもよい。化成処理皮膜は、公知の方法で形成されうる。たとえば、化成処理液をロールコート法、スピンコート法、スプレー法などの方法でエンボスステンレス鋼板の表面に塗布し、水洗せずに乾燥させればよい。乾燥温度および乾燥時間は、水分を蒸発させることができれば特に限定されない。生産性の観点からは、乾燥温度は到達板温で６０〜１５０℃の範囲内が好ましく、乾燥時間は２〜１０秒の範囲内が好ましい。 As described above, the embossed stainless steel plate serving as the coating original plate may have a chemical conversion treatment film formed thereon. The chemical conversion film can be formed by a known method. For example, the chemical conversion solution may be applied to the surface of the embossed stainless steel plate by a method such as a roll coating method, a spin coating method, or a spray method, and dried without being washed with water. The drying temperature and drying time are not particularly limited as long as moisture can be evaporated. From the viewpoint of productivity, the drying temperature is preferably in the range of 60 to 150 ° C. as the ultimate plate temperature, and the drying time is preferably in the range of 2 to 10 seconds.
２）第２のステップ
第２のステップでは、第１のステップで準備したエンボスステンレス鋼板の表面に有色塗料を塗布する。
2) Second Step In the second step, a colored paint is applied to the surface of the embossed stainless steel plate prepared in the first step.
前述の通り、有色塗料の主成分となる有機樹脂の種類は、特に限定されず、製造方法（プレコート方式またはポストコート方式）や用途などに応じて適宜選択されうる。また、有色塗膜を着色する着色顔料の種類も、塗装原板を構成するステンレス鋼と有色塗膜との色差を十分に大きくすることができれば特に限定されない。 As described above, the type of the organic resin that is the main component of the colored paint is not particularly limited, and may be appropriately selected according to the production method (pre-coating method or post-coating method), application, and the like. Further, the kind of the color pigment for coloring the colored coating film is not particularly limited as long as the color difference between the stainless steel constituting the coating original plate and the colored coating film can be sufficiently increased.
有色塗料の溶剤の種類は、主成分となる有機樹脂を溶解しうる溶剤であれば、特に限定されない。使用しうる溶剤の例には、トルエン、キシレン、高沸点石油系炭化水素などの炭化水素系溶剤；メチルエチルケトン、メチルイソブチルケトン、シクロヘキサノン、イソホロンなどのケトン系溶剤；酢酸エチル、酢酸ブチル、エチレングリコールモノエチルエーテルアセテート、ジエチレングリコールモノエチルエーテルアセテートなどのエステル系溶剤；メタノール、エタノール、ブタノールなどのアルコール系溶剤；エチレングリコールモノエチルエーテル、エチレングリコールモノブチルエーテル、ジエチレングリコールモノブチルエーテルなどのエーテルアルコール系溶剤などが含まれる。これらの溶剤は、単独で用いられてもよいし、２種以上を組み合わせて用いられてもよい。 The type of solvent for the colored paint is not particularly limited as long as it is a solvent that can dissolve the organic resin as the main component. Examples of solvents that can be used include hydrocarbon solvents such as toluene, xylene, and high-boiling petroleum hydrocarbons; ketone solvents such as methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, and isophorone; ethyl acetate, butyl acetate, and ethylene glycol mono Includes ester solvents such as ethyl ether acetate and diethylene glycol monoethyl ether acetate; alcohol solvents such as methanol, ethanol and butanol; ether alcohol solvents such as ethylene glycol monoethyl ether, ethylene glycol monobutyl ether and diethylene glycol monobutyl ether . These solvents may be used alone or in combination of two or more.
有色塗料の塗布方法は、特に限定されず、製造方法（プレコート方式またはポストコート方式）などに応じて適宜選択されうる。塗布方法の例には、ロールコート法、フローコート法、カーテンフロー法、スプレー法、浸漬法などが含まれる。 The method for applying the colored paint is not particularly limited, and can be appropriately selected according to the production method (precoat method or postcoat method). Examples of the coating method include a roll coating method, a flow coating method, a curtain flow method, a spray method, and an immersion method.
有色塗料の塗布量は、特に限定されないが、焼き付けた後（または硬化させた後）の凹部（平坦部）における乾燥膜厚が３μｍ以上となる量であることが好ましい。凹部の乾燥膜厚を３μｍ以上とすることで、凸部の頂面とそれ以外の領域との色差ΔＥを１以上とすることができる。また、カラークリア塗膜以外の透明性の低い有色塗膜を形成する場合に、工業製品として安定的な下地隠蔽性を実現することができる。一方、製造性の観点からは、凹部における液膜（第３のステップで塗料を除去する場合）または塗膜（第３のステップで塗膜を除去する場合）の厚さが凸部の高さ未満となるように有色塗料の塗布量を調整することが好ましい。凹部の液膜または塗膜の厚さが凸部の高さ以上の場合、第３のステップにおいて凸部の頂面の有色塗料または有色塗膜を除去することが困難となる。また、プレコート方式で有色塗料を焼き付けて有色塗膜を形成する場合は、凹部の１層ごとの乾燥膜厚が３０μｍ以下となるように有色塗料の塗布量を調整することが好ましい。１層の乾燥膜厚が３０μｍを超える場合、有色塗料を焼き付ける際にワキと称される外観不良が生じやすいからである。 The coating amount of the colored paint is not particularly limited, but it is preferably an amount such that the dry film thickness in the concave portion (flat portion) after baking (or after curing) is 3 μm or more. By setting the dry film thickness of the concave portion to 3 μm or more, the color difference ΔE between the top surface of the convex portion and the other region can be set to 1 or more. Moreover, when forming a colored coating film with low transparency other than a color clear coating film, a stable base concealing property as an industrial product can be realized. On the other hand, from the viewpoint of manufacturability, the thickness of the liquid film in the concave portion (when the paint is removed in the third step) or the coating film (when the coating film is removed in the third step) is the height of the convex portion. It is preferable to adjust the coating amount of the colored paint so as to be less than the above. When the thickness of the liquid film or coating film in the concave portion is equal to or higher than the height of the convex portion, it is difficult to remove the colored paint or the colored coating film on the top surface of the convex portion in the third step. In addition, when a colored coating is formed by baking a colored coating by a precoat method, it is preferable to adjust the coating amount of the colored coating so that the dry film thickness for each layer of the recesses is 30 μm or less. This is because, when the dry film thickness of one layer exceeds 30 μm, an appearance defect called “Waki” tends to occur when baking a colored paint.
前述の通り、塗布された有色塗料は、第３のステップの前または後に焼き付けられる（または硬化させられる）。有色塗料の焼き付け条件（温度、時間）は、特に限定されず、有色塗料の種類に応じて適宜設定されうる。 As described above, the applied colored paint is baked (or cured) before or after the third step. The baking conditions (temperature, time) of the colored paint are not particularly limited, and can be appropriately set according to the type of the colored paint.
３）第３のステップ
第３のステップでは、エンボスステンレス鋼板の凸部の頂面の有色塗料または有色塗膜を除去する。このとき、有色塗料を焼き付けて（または硬化させて）有色塗膜を形成した後に凸部の頂面の有色塗膜を除去してもよいし、有色塗料を焼き付ける（または硬化させる）前に凸部の頂面の有色塗料を除去してもよい。後者の場合は、凸部の頂面の有色塗料を除去した後に、凸部の側面および凹部の底面に残っている有色塗料を焼き付ける（または硬化させる）。
3) Third Step In the third step, the colored paint or colored coating film on the top surface of the convex portion of the embossed stainless steel plate is removed. At this time, after the colored paint is baked (or cured) to form the colored coating film, the colored coating film on the top surface of the convex portion may be removed, or the projected color before the colored paint is baked (or cured). The colored paint on the top surface of the part may be removed. In the latter case, after removing the colored paint on the top surface of the convex portion, the colored paint remaining on the side surface of the convex portion and the bottom surface of the concave portion is baked (or cured).
乾燥塗膜を形成した後に凸部の頂面の有色塗膜を除去する場合、有色塗膜の除去方法は特に限定されない。有色塗膜の除去方法の例には、研磨などによる機械的な除去、溶解などによる化学的な除去が含まれる。凸部頂面の有色塗膜を研磨除去する場合、使用可能な研磨装置の例としては、ベルト型研磨装置、ロール型研磨装置、ホイール型研磨装置、ポリッシャー型研磨装置が含まれる。有色塗膜を除去する際に所定の研磨剤を使用したり、有色塗膜を除去した後に別途再研磨したりすることにより、凸部頂面にヘアーラインなどの研磨模様を意図的に付与することもできる。 When the colored coating film on the top surface of the convex portion is removed after the dry coating film is formed, the method for removing the colored coating film is not particularly limited. Examples of the method for removing the colored coating include mechanical removal by polishing or the like, and chemical removal by dissolution or the like. In the case of polishing and removing the colored coating film on the top surface of the convex portion, examples of usable polishing apparatuses include a belt type polishing apparatus, a roll type polishing apparatus, a wheel type polishing apparatus, and a polisher type polishing apparatus. By using a predetermined abrasive when removing the colored coating, or by re-polishing separately after removing the colored coating, intentionally imparting a polishing pattern such as a hairline to the top of the convex part You can also.
一方、有色塗料を焼き付ける（または硬化させる）前に有色塗料を除去する場合、有色塗料の除去方法は特に限定されない。有色塗料の除去方法の例には、拭き取りによる方法、平滑な面やロールと接触させて凸部の頂面の塗料を転写させる方法、ドクターナイフなどにより凸部の頂面の塗料を削ぎ取る方法などが含まれる。 On the other hand, when removing the colored paint before baking (or curing) the colored paint, the method for removing the colored paint is not particularly limited. Examples of methods for removing colored paints include a method of wiping, a method of transferring the paint on the top surface of the convex part by contacting with a smooth surface or a roll, a method of scraping the paint on the top surface of the convex part with a doctor knife, etc. Etc. are included.
以上の手順により、凸部の頂面はステンレス鋼の色調を呈し、それ以外の領域は有色塗膜の色調を呈する塗装エンボスステンレス鋼板を製造することができる。 By the above procedure, it is possible to produce a coated embossed stainless steel plate in which the top surface of the convex portion exhibits the color tone of stainless steel and the other regions exhibit the color tone of the colored coating film.
本発明の製造方法では、有色塗料を塗布した後に凸部の頂面上の有色塗料または有色塗膜を除去するため、凸部の頂面上に有色塗膜が付着することはなく、凸部の頂面とそれ以外の領域とを高精度に塗り分けることができる。 In the production method of the present invention, the colored paint or colored coating film on the top surface of the convex portion is removed after the colored paint is applied, so that the colored coating film does not adhere to the top surface of the convex portion. It is possible to coat the top surface and other regions with high accuracy.
３．実施の形態
以下、本発明の実施の形態について、図面を参照して詳細に説明する。ここでは、水玉柄のエンボスステンレス鋼板を塗装原板とした本発明の塗装エンボスステンレス鋼板の例を説明する。
3. DESCRIPTION OF EMBODIMENTS Embodiments of the present invention will be described in detail below with reference to the drawings. Here, the example of the embossed stainless steel plate of this invention which used the embossed stainless steel plate of the polka dot pattern as the coating original plate is demonstrated.
図１は、本発明の一実施の形態に係る塗装エンボスステンレス鋼板１００を示す模式図である。図１Ａは塗装エンボスステンレス鋼板１００の平面図であり、図１Ｂは塗装エンボスステンレス鋼板１００の断面図である。 FIG. 1 is a schematic view showing a coated embossed stainless steel plate 100 according to an embodiment of the present invention. 1A is a plan view of the coated embossed stainless steel plate 100, and FIG. 1B is a cross-sectional view of the coated embossed stainless steel plate 100.
図１Ａに示されるように、塗装エンボスステンレス鋼板１００の表面には、円柱状の凸部１１０が規則正しく配列されており、凸部１１０の間に凹部１２０が存在している。図１Ｂに示されるように、それぞれの凸部１１０の高さは同一である。したがって、それぞれの凸部１１０の頂面は同一平面状に位置している。また、凸部１１０の頂面は平面である。 As shown in FIG. 1A, columnar convex portions 110 are regularly arranged on the surface of the coated embossed stainless steel plate 100, and the concave portions 120 exist between the convex portions 110. As shown in FIG. 1B, the height of each convex portion 110 is the same. Therefore, the top surface of each convex part 110 is located on the same plane. Moreover, the top surface of the convex part 110 is a plane.
図１Ｂに示されるように、塗装エンボスステンレス鋼板１００は、塗装原板であるエンボスステンレス鋼板１３０と、エンボスステンレス鋼板１３０の表面に形成された有色塗膜１４０とを有する。 As shown in FIG. 1B, the painted embossed stainless steel plate 100 includes an embossed stainless steel plate 130 that is a coated original plate, and a colored coating film 140 formed on the surface of the embossed stainless steel plate 130.
エンボスステンレス鋼板１３０は、表面に複数の微細な凸部１１０を形成するエンボス加工が施されたステンレス鋼板である。前述の通り、本実施の形態の塗装エンボスステンレス鋼板１００では、凸部１１０の形状は円柱状である。しかしながら、凸部１１０の頂面の面積と底面の面積は、完全に同一でなくてもよい。すなわち、凸部１１０の形状は円錐台状であってもよい。凸部１１０の直径は１００μｍ〜５ｍｍであり、高さは５〜１００μｍ程度である。また、凸部１１０間の間隔は、５００μｍ〜１０ｍｍである。 The embossed stainless steel plate 130 is a stainless steel plate that has been embossed to form a plurality of fine protrusions 110 on the surface. As described above, in the coated embossed stainless steel plate 100 of the present embodiment, the shape of the convex portion 110 is a columnar shape. However, the area of the top surface and the area of the bottom surface of the protrusion 110 may not be completely the same. That is, the shape of the convex part 110 may be a truncated cone. The diameter of the convex part 110 is 100 micrometers-5 mm, and height is about 5-100 micrometers. Moreover, the space | interval between the convex parts 110 is 500 micrometers-10 mm.
有色塗膜１４０は、エンボスステンレス鋼板１３０の凸部１１０の側面および凹部（平坦部）１２０を被覆している。一方、エンボスステンレス鋼板１３０の凸部１１０の頂面は、有色塗膜１４０により被覆されておらず、ステンレス鋼が露出している。エンボスステンレス鋼板１３０の凸部１１０の頂面で露出しているステンレス鋼と有色塗膜１４０との色差ΔＥが１以上となるように、有色塗膜１４０は着色されている。凹部１２０における有色塗膜１４０の膜厚は、３〜３０μｍである。 The colored coating film 140 covers the side surface of the convex part 110 and the concave part (flat part) 120 of the embossed stainless steel plate 130. On the other hand, the top surface of the convex portion 110 of the embossed stainless steel plate 130 is not covered with the colored coating film 140 and the stainless steel is exposed. The colored coating film 140 is colored so that the color difference ΔE between the stainless steel exposed on the top surface of the convex portion 110 of the embossed stainless steel plate 130 and the colored coating film 140 is 1 or more. The film thickness of the colored coating film 140 in the recess 120 is 3 to 30 μm.
次に、図２を参照して、塗装エンボスステンレス鋼板１００の製造方法を説明する。図２Ａ〜Ｃは、塗装エンボスステンレス鋼板１００の製造過程を示す模式図である。 Next, with reference to FIG. 2, the manufacturing method of the coating embossed stainless steel plate 100 is demonstrated. 2A to 2C are schematic views showing the manufacturing process of the coated embossed stainless steel plate 100. FIG.
まず、図２Ａに示されるように、エンボス加工が施されて、凸部１１０および凹部１２０が形成されたエンボスステンレス鋼板１３０を準備する。エンボスステンレス鋼板１３０の表面は、化成処理を施されていてもよい。 First, as shown in FIG. 2A, an embossed stainless steel plate 130 is prepared that is embossed to form a convex portion 110 and a concave portion 120. The surface of the embossed stainless steel plate 130 may be subjected to chemical conversion treatment.
次に、図２Ｂに示されるように、エンボスステンレス鋼板１３０の表面に有色塗膜１４０を形成する。具体的には、エンボスステンレス鋼板１３０の表面に有色塗料を塗布し、所定の条件で焼き付ける。このとき、有色塗膜１４０は、エンボスステンレス鋼板１３０の凹部１２０のみだけでなく、凸部１１０にも形成される。 Next, as shown in FIG. 2B, a colored coating film 140 is formed on the surface of the embossed stainless steel plate 130. Specifically, a colored paint is applied to the surface of the embossed stainless steel plate 130 and baked under predetermined conditions. At this time, the colored coating film 140 is formed not only on the concave portion 120 of the embossed stainless steel plate 130 but also on the convex portion 110.
最後に、図２Ｃに示されるように、エンボスステンレス鋼板１３０の凸部１１０の頂面に形成された有色塗膜１４０を除去する。たとえば、凸部１１０の頂面に形成された有色塗膜１４０を研磨して除去すればよい。このように研磨した場合、凸部１１０の頂面は平面となり、かつ凸部１１０の高さは同一となる。 Finally, as shown in FIG. 2C, the colored coating film 140 formed on the top surface of the convex portion 110 of the embossed stainless steel plate 130 is removed. For example, the colored coating film 140 formed on the top surface of the convex portion 110 may be polished and removed.
