Description
本発明は鉄被塗物の錆面への塗装が可能であって、優れた防錆性と耐候性を賦与出来る錆転換用水系塗料に関する。
The present invention relates to a water-based paint for rust conversion that can be applied to a rust surface of an iron coating and can provide excellent rust prevention and weather resistance.
【０００２】
一般に、鉄被塗物の錆面への塗装は錆を完全に取り除く素地調整（ケレン）をして、初めて防錆力のある溶剤系の下塗り塗料を塗布し、次いで耐候性のある溶剤系の上塗り塗料を塗布することができ、この結果鉄被塗物に防錆力と耐候性を付与することができる。
【発明の開示】
【発明が解決しようとする課題】[0002]
In general, iron coating is applied to the rusted surface by completely adjusting the surface to remove rust (Kellen), applying a rust-preventing solvent-based primer coating for the first time, and then applying a weather-resistant solvent-based coating. A top coating can be applied, and as a result, rust prevention and weather resistance can be imparted to the iron coating.
DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
しかし乍ら、近年環境保護の面で溶剤を使用しない下塗り塗料や上塗り塗料が要求されており、無溶剤系や水系の下塗り塗料や上塗り塗料が検討されている。 However, in recent years, an undercoat or topcoat that does not use a solvent is required in terms of environmental protection, and solventless or water-based undercoats and topcoats are being studied.
一方鉄被塗物の錆面への塗装については、鉄被塗物の錆面の錆を完全に取り除く素地調整（ケレン）がおこなわれていない状態では、優れた防錆性と耐候性とを有する塗料が全く開発されておらず、水系の塗料でしかも鉄被塗物の錆面の錆を完全に取り除く素地調整（ケレン）がおこなわれていない条件でも、優れた防錆性を有する塗料が現在強く望まれている。 On the other hand, with regard to the coating of rusted surfaces of iron coatings, excellent rust prevention and weather resistance can be achieved in a state where the substrate adjustment (Kellen) has not been performed to completely remove rust on the rusting surfaces of iron coatings. No paint has been developed, and it is a water-based paint that has excellent anti-rust properties even under conditions that do not have a ground preparation (keren) that completely removes rust on the rust surface of the iron coating. Currently strongly desired.
したがって、本発明は鉄被塗物の錆面の錆を完全に取り除く素地調整（ケレン）がおこなわれていない場合、即ち浮き錆を簡易に除去する程度の素地調整で鉄被塗物の錆面に塗装可能で、しかも優れた防錆性と耐候性を有する錆転換用水系塗料を提供することを目的とする。 Therefore, in the present invention, the rust surface of the iron coating is not adjusted to completely remove the rust on the rust surface of the iron coating, that is, the rust surface of the iron coating is simply adjusted to remove floating rust easily. An object of the present invention is to provide a water-based paint for rust conversion which can be painted on the surface and has excellent rust prevention and weather resistance.

本発明者らは、斯かる現状に鑑み、浮き錆を簡易に除去する程度の素地調整で、鉄被塗物の錆面に塗装可能で、しかも優れた防錆性と耐候性を有する錆転換用水系塗料を開発すべく研究を重ねてきた。この結果、ポリフェノール誘導体、亜リン酸塩、及びステンレス合金粉末を、上記特定のアクリル変性複合エマルジョンに含有せしめた水系組成物が、従来の塗料の上記問題点を解消しうることを見出し、本発明を完成するに至った。

In view of the current situation, the present inventors can coat the rust surface of an iron coated article with a base adjustment that easily removes floating rust, and has excellent rust prevention and weather resistance.

Can be used in combination. Of these, gallic acid and tannic acid are particularly preferred from the viewpoint of rust prevention.
本発明に於いて使用する亜リン酸塩は、亜リン酸カルシウムと亜リン酸マグネシウムであり、これ等は単独でまたは併用して使用することができる。 The phosphites used in the present invention are calcium phosphite and magnesium phosphite, and these can be used alone or in combination.
本発明のステンレス合金粉末は公知のステンレス鋼の粉末状及びフレーク状のものである。例えばステンレス鋼は、オーステナイト系、フェライト系、マルテンサイト系などのステンレス鋼が例示できる。粉末の大きさは５〜１００μ、フレーク状の大きさは５〜１００μのものが好ましい。 The stainless alloy powder of the present invention is a known stainless steel powder and flake. For example, examples of the stainless steel include austenitic, ferritic, and martensitic stainless steels. The size of the powder is preferably 5 to 100 μm, and the flake size is preferably 5 to 100 μm.
本発明に於いて使用するアクリル変性複合エマルジョンは、アクリル樹脂エマルジョン、アクリル−酢酸ビニル樹脂エマルジョン、アクリル−エチレン酢酸ビニル樹脂エマルジョン、シリコンアクリル樹脂エマルジョン、アクリルニトリル−塩化ビニル−塩化ビニリデン共重合体エマルジョン、アクリルウレタン樹脂エマルジョン、およびアクリルエポキシ樹脂エマルジョンの少なくとも１種である。 The acrylic modified composite emulsion used in the present invention is an acrylic resin emulsion, an acrylic-vinyl acetate resin emulsion, an acrylic-ethylene vinyl acetate resin emulsion, a silicon acrylic resin emulsion, an acrylonitrile-vinyl chloride-vinylidene chloride copolymer emulsion, At least one of an acrylic urethane resin emulsion and an acrylic epoxy resin emulsion .
アクリル変性複合エマルジョンの最低造膜温度（ＭＦＴ）は、錆への浸透性や作業性の点で、０〜４０℃が好ましい。これらの中でも、アクリル樹脂エマルジョン、アクリルウレタン樹脂エマルジョン、シリコンアクリル樹脂エマルジョン、アクリルニトリル−塩化ビニル−塩化ビニリデン共重合体エマルジョンが好ましい。これらの樹脂は単独或いは２種以上の混合系で用いることができる。 The minimum film-forming temperature (MFT) of the acrylic-modified composite emulsion is preferably 0 to 40 ° C. from the viewpoint of permeability to rust and workability. Among these, an acrylic resin emulsion, an acrylic urethane resin emulsion, a silicon acrylic resin emulsion, and an acrylonitrile-vinyl chloride-vinylidene chloride copolymer emulsion are preferable. These resins can be used alone or in a mixture of two or more.
本発明に於いて使用する上記アクリル変性複合エマルジョンと、ポリフェノール誘導体、亜リン酸塩、及びステンレス合金粉末との使用割合は、アクリル変性複合エマルジョンの固形分１００重量部に対して、ポリフェノール誘導体２〜２０重量部、亜リン酸塩２〜２０重量部、ステンレス合金粉末５〜５０重量部である。 The ratio of the acrylic modified composite emulsion used in the present invention to the polyphenol derivative, phosphite, and stainless steel alloy powder is 2 to 100 parts by weight of the solid content of the acrylic modified composite emulsion. 20 parts by weight, 2 to 20 parts by weight of phosphite, and 5 to 50 parts by weight of stainless alloy powder .
ポリフェノール誘導体２重量部未満では、錆への密着性が低下し、防錆性も低する。２０重量部を超えると耐水性が低下する。 If it is less than 2 weight part of polyphenol derivatives, the adhesiveness to rust will fall and rust prevention property will also fall. If it exceeds 20 parts by weight, the water resistance decreases.
亜リン酸塩が２重量部未満では防錆性が低下し、２０重量部を超えると耐水性が低下する。 When the amount of phosphite is less than 2 parts by weight, the rust resistance is lowered, and when it exceeds 20 parts by weight, the water resistance is lowered.
ステンレス合金粉末が５重量部未満では耐候性が低下し、逆に５０重量部を超えると作業性が低下し密着性が低下する。 When the stainless alloy powder is less than 5 parts by weight, the weather resistance is lowered. On the other hand, when it exceeds 50 parts by weight, the workability is lowered and the adhesiveness is lowered.
本発明の錆転換用水系塗料には、必要に応じて、塗料特性や接着特性を向上させるために、公知の各種の添加剤を使用することができる。例えば、界面活性剤等の分散剤、レベリング剤、カップリング剤、増粘剤、顔料、可塑剤、充填剤、架橋剤などの添加剤を適宜に混ぜることができる。 In the water-based paint for rust conversion of the present invention, various known additives can be used as required in order to improve paint properties and adhesive properties. For example, a dispersant such as a surfactant, a leveling agent, a coupling agent, a thickener, a pigment, a plasticizer, a filler, a cross-linking agent, and the like can be appropriately mixed.
本発明の錆転換用水系塗料はポリフェノール誘導体、亜リン酸塩、及びステンレス合金粉末をアクリル変性複合エマルジョンに公知の方法で混合、分散することにより容易に製造することができる。本発明の錆転換用水系塗料のＰＨは７．０〜１０．０の範囲に調整され、必要に応じ水で希釈して使用される。 The water-based paint for rust conversion of the present invention can be easily produced by mixing and dispersing a polyphenol derivative, a phosphite, and a stainless alloy powder in an acrylic-modified composite emulsion by a known method. The pH of the water-based paint for rust conversion of the present invention is adjusted to a range of 7.0 to 10.0, and is diluted with water as necessary.
本発明の錆転換用水系塗料が、水系の塗料でしかも鉄被塗物の錆面の錆を完全に取り除く素地調整（ケレン）がおこなわれていない条件でも、優れた防錆性と耐候性を有する機能は、本発明者らによると次のように考察される。即ち、鉄被塗物の錆面の錆（酸化鉄）を、ポリフェノール誘導体と亜リン酸塩により安定で緻密で防錆性のある四三酸化鉄に転換し、しかもステンレス合金粉末とアクリル変性複合エマルジョンに併用することにより、塗料の安定性と優れた耐候性が得られる。The water-based paint for rust conversion according to the present invention is a water-based paint and has excellent rust prevention and weather resistance even under conditions where the substrate is not completely adjusted to remove the rust on the rust surface of the iron coating. The functions possessed by the present inventors are considered as follows. That is, the rust (iron oxide) on the rust surface of the iron coating is converted into a stable, dense and rust-proof iron tetroxide by polyphenol derivative and phosphite, and the stainless alloy powder and acrylic modified composite By using it together with the emulsion, the stability of the paint and excellent weather resistance can be obtained.
本発明の錆転換用水系塗料の使用方法は、鉄被塗物の錆面の錆を完全に取り除く素地調製（ケレン）がおこなわれていない条件、即ち浮き錆を簡易に除去する程度の素地調製で鉄被塗物の錆面に従来どおり塗装すればよく、その結果優れた防錆性と耐候性を有する錆転換用水系塗料を提供することができる。また、本発明の錆転換用水系塗料の使用は錆の発生していない鉄被塗物や錆を完全に取り除いた鉄被塗物へも使用することができる。The method of using the water-based paint for rust conversion according to the present invention is the condition that the base preparation (keren) that completely removes rust on the rust surface of the iron coating is not performed, that is, the base preparation that can easily remove floating rust Thus, it is only necessary to paint on the rust surface of the iron coating as usual, and as a result, it is possible to provide a water-based paint for rust conversion having excellent rust prevention and weather resistance. Further, the use of the water-based paint for converting rust of the present invention can be used for an iron coating without rust and an iron coating from which rust has been completely removed.
