〔産業上の利用分野〕
本発明は、冷蔵庫の表面に用いる非常に高度の表面特性
を必要とされる化粧鋼板の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing decorative steel sheets for use on the surfaces of refrigerators, which require very high surface properties.
従来から化粧鋼板は、鋼板の表面に熱硬化型塗料を塗布
後、焼付乾燥を行なうものであり、加工性、経済性等に
より種々の用途に用いられている。Decorative steel sheets have traditionally been produced by applying a thermosetting paint to the surface of the steel sheet and then baking and drying it, and it has been used for various purposes due to its workability, economy, etc.
しかしながら近年、高い表面特性がますます求められ、
特に冷蔵庫の表面材等では、表面の塗膜欠陥に対する要
求水準が極めて高くなっている。However, in recent years, there has been an increasing demand for high surface properties.
Particularly in the case of surface materials for refrigerators, etc., the level of requirements for surface coating film defects has become extremely high.
そのため従来からの焼付乾燥方式では、収率が悪く、十
分に要求を満すものではなくなってしまった。Therefore, the conventional baking drying method has a poor yield and no longer satisfies the requirements.
本考案は、上記問題点を解決し、表面塗膜の欠陥を低減
すると共に、極めて平滑な表面特性を有する化粧鋼板の
製造方法を提供することを目的とする。The present invention aims to solve the above-mentioned problems, reduce defects in the surface coating film, and provide a method for producing a decorative steel sheet having extremely smooth surface characteristics.
鋼板の表面に隠蔽性を有する熱硬化型樹脂塗膜からなる

The problem was solved by attaching a transparent film to the surface and irradiating the transparent film with ultraviolet rays from the outside to cure the transparent protective coating.
透明保護塗膜層が未硬化状態の時に透明フィルムを密着

面に、ごみ等の異物の付着がない状態なので平滑性の優
れた化粧鋼板が得られる。When the transparent protective coating layer is in an uncured state, a transparent film is brought into close contact with the transparent protective coating layer, and the transparent protective coating layer is cured as it is, so there is no foreign matter such as dust attached to the surface, resulting in a decorative steel sheet with excellent smoothness. can get.
まず、鋼板の表面に隠蔽性を有する熱硬化型樹脂塗膜か
らなる下地塗膜層上に紫外線硬化型樹脂塗膜からなる透
明保護塗膜層を設ける。First, a transparent protective coating layer made of an ultraviolet curable resin coating is provided on the surface of a steel plate on a base coating layer made of a thermosetting resin coating having concealing properties.
そして、該透明保護産膜層が未硬化状態のときに、表面

する化粧鋼板の製造方法である。Then, when the transparent protective coating layer is in an uncured state, a transparent film is closely attached to the surface, and in that state, ultraviolet rays are irradiated from the outside of the transparent film to harden the transparent protective coating layer, thereby producing a decorative steel sheet. It's a method.
ここで、鋼板は０．２〜０．８龍の厚さで、スキンパス
処理を施した化成処理鋼板または亜鉛メッキ鋼板が適し
ており、必要ならば通常の塗装前処理や、さらにブライ
マー塗装を行なってもよい。Here, the steel plate is suitably a chemical conversion treated steel plate or a galvanized steel plate with a thickness of 0.2 to 0.8 mm, which has been subjected to a skin pass treatment, and if necessary, a normal pre-painting treatment or a brimer coating is applied. You can.

いることができる。In addition, for the base coating layer, a resin made by mixing acrylic resin or polyester resin with melamine resin or/and pe/zoguanamine resin is suitable.
．． As the UV-curable resin paint, commonly used materials such as acrylic oligomer-based, acrylic urethane-based, and unsaturated polyester-based paints can be used.
下地塗膜層として、アクリル系樹脂またはポリニスナル

樹脂を混合した樹脂を用いたので、鋼板との密着性が優
れているばかりでなく、紫外線硬化型樹脂塗料からなる
透明保護塗膜層との密着性も良好となる。As the base coating layer uses a resin that is a mixture of acrylic resin or polynisnal resin and melamine resin and/or benzoguanamine resin, it not only has excellent adhesion to the steel plate, but also consists of an ultraviolet curable resin paint. Adhesion to the transparent protective coating layer also becomes better.

塗膜層との密着性および剥離性から最も適している。Furthermore, as a transparent film, polyethylene terephthalate film with a thickness of 12 to 58 μm is used.
Although a 0μ thick polypropylene film or a vinylon film can be used, a 12-25μ thick polyester film is most suitable in terms of transparency, smoothness, and adhesion and releasability to the transparent protective coating layer.
上記方法によりて製造された化粧鋼板は、使用時には、
表面の透明フィルムを剥離し、透明塗膜層を最外層とし
て使用する。When using the decorative steel sheet manufactured by the above method,
Peel off the transparent film on the surface and use the transparent coating layer as the outermost layer.
そのため、透明フィルムは、製造時には表面を平滑に仕
上げ、製造後は、保護フィルムとしての役割をなすもの
である。Therefore, the surface of the transparent film is smoothed during manufacture, and after manufacture it serves as a protective film.

に厚さ２５μのポリエチＶ／テレフタレートフィルムか
らなる透明フィルムを密着させる。A single layer of 2μ thick epoxy resin primer containing anti-rust pigment is formed on the surface of a 0.51 mm thick galvanized steel plate, and a base coat of 25μ thick thermosetting polyester resin mixed with melamine resin is applied on the primer layer. After providing a film layer and applying an ultraviolet curable acrylic resin paint to a thickness of 10 μm, a transparent film made of polyethylene V/terephthalate film having a thickness of 25 μm is immediately attached.
そして、透明フィルムの外側から高圧水銀灯により紫外
線を照射して透明樹脂塗膜層を形成した。Then, ultraviolet rays were irradiated from the outside of the transparent film using a high-pressure mercury lamp to form a transparent resin coating layer.

み、異物等の塗装欠陥も全く紹められなかりた。When the decorative steel sheet obtained in this way and cut into predetermined dimensions was used by peeling off the transparent film immediately before use, the surface of the transparent resin coating layer was extremely smooth and free from dirt, foreign matter, etc. No flaws were introduced at all.

な表面状態が得られる。In the manufacturing method of the present invention, the surface of the transparent protective coating layer made of an ultraviolet curable resin coating is coated with a transparent film and irradiated with ultraviolet rays while the transparent protective coating layer is in an uncured state. There is no adhesion of foreign matter such as dust, and an extremely smooth surface can be obtained.
また、透明フィルムは、最終製品の段階まで剥離される
ことがないため、切断、＠包、輸送、加工等の中間段階

が極めて少ない。In addition, since the transparent film is not peeled off until the final product is produced, there is no damage or dirt adhesion during intermediate stages such as cutting, packaging, transportation, and processing, which greatly reduces the occurrence of defects during each process. few.
また、透明フィルムの平滑性の異なるフィルムを目的に
