技術分野  Technical field
本発明は、 新規な被膜形成可能なキレー ト形成性樹脂 その製造方法、 その用途及び電着塗膜形成方法に関する  The present invention relates to a chelate-forming resin capable of forming a novel film, a method for producing the same, a use thereof, and a method for forming an electrodeposition film.
背景技術  Background art
従来、 金属の腐食を防止するために、 リ ン酸塩やクロ ム酸塩等の無機質被膜を金属素材表面に形成する金属表 面処理、 エポキシ樹脂やフユノール樹脂等の有機質被膜 を金属表面に形成する塗膜防食の技術、 等が利用されて きた。  Conventionally, to prevent metal corrosion, metal surface treatment to form an inorganic film such as phosphate or chromate on the surface of the metal material, and organic film such as epoxy resin or fuanol resin to the metal surface The technology of coating corrosion protection has been used.
しかしながら、 金属表面処理の場合、 重金属廃液によ る環境汚染公害の発生、 酸 · アルカリ · シァン等の劇毒 物の使用、 複雑な工程を要する、 といった欠点がある。  However, in the case of metal surface treatment, there are drawbacks such as generation of environmental pollution due to heavy metal waste liquid, use of toxic substances such as acid, alkali and cyanide, and a complicated process.
また、 塗膜防食の場合、 金属との結合力が腐食反応を 完全に抑える程強固ではないといつた問題がある。  Also, in the case of coating corrosion protection, there is a problem that the bonding strength with metal is not strong enough to completely suppress the corrosion reaction.
従って、 現在、 無公害で実用性があり、 優れた防食性 を示す防食技術が確立されておらず、 その開発が待たれ ている。  Therefore, at present, no anticorrosion technology that is pollution-free and practical and has excellent anticorrosion properties has not been established, and its development is awaited.
一方、 自動車車体や電気機器などの塗装においては、 金属表面の防食性、 金属表面と塗装塗膜との密着性、 塗 膜の仕上り外観や耐久性、 生産性などの観点から、 金属 の塗装前処理として上記リ ン酸塩で表面処理し、 プライ マーとして電着塗料を塗装することが幅広く採用されて いる。 On the other hand, in the coating of automobile bodies and electrical equipment, the corrosion resistance of the metal surface, the adhesion between the metal surface and the paint film, From the viewpoints of the finished appearance of the film, durability and productivity, it has been widely adopted to apply a surface treatment with the above phosphate as a pretreatment for metal coating and apply an electrodeposition paint as a primer.
しかし、 この場合において、 電着塗料は低公害塗料で あるが、 リ ン酸塩処理についてみると、 リ ン酸塩処理工 程からの廃水中のリ ンが水質の富栄養化をもたらし水質 汚染の原因になっていることや、 将来、 リ ンの供給不足 が予想されていることなどから、 リ ン酸塩処理に代わる 新しい塗装前処理方法の開発が急務となっている。  However, in this case, the electrodeposition paint is a low-pollution paint, but regarding the phosphate treatment, phosphorus in the wastewater from the phosphate treatment process leads to eutrophication of the water quality and water pollution. It is urgently necessary to develop a new paint pretreatment method to replace the phosphate treatment, because of the cause of such problems and the shortage of phosphorus supply in the future.
