Description
本発明は、一液型水性塗料組成物に関し、詳しくは黒皮鋼材に対する付着力に優れた一液型水性塗料組成物に関する。 The present invention relates to a one-component water-based paint composition, and more specifically to a one-component water-based paint composition that has excellent adhesion to black steel materials.
建設機械や産業機械のライン塗装では、種々の基材に対する付着性や耐食性が求められるため、これら性能の優れる溶剤系塗料が一般的に用いられていた。しかし近年では、環境保護の観点から有害大気汚染物質や揮発性有機化合物が規制されており、建機向けのライン塗装においても溶剤系塗料から水系塗料への転換が検討されている(特許文献1)。 In the line painting of construction and industrial machinery, adhesion to various substrates and corrosion resistance are required, so solvent-based paints, which have excellent performance in these areas, have been commonly used. However, in recent years, harmful air pollutants and volatile organic compounds have been regulated from the perspective of environmental protection, and a shift from solvent-based paints to water-based paints is being considered for line painting of construction machinery as well (Patent Document 1).
一方で建設機械や産業機械は部品により鋼材の種類が異なることが多く、鉄やステンレス、アルミニウム等の様々な金属が用いられる。そのため、建設機械用の塗料には、種々の基材に対する付着性が求められるが、従来の建設機械向け水系塗料ではいまだ十分な性能が得られなかった(特許文献2)。 On the other hand, construction and industrial machinery often use different types of steel for different parts, and various metals such as iron, stainless steel, and aluminum are used. Therefore, paints for construction machinery are required to have adhesion to a variety of substrates, but conventional water-based paints for construction machinery have not yet achieved sufficient performance (Patent Document 2).
中でも、表面にミクロな凹凸が存在する黒皮鋼材(表面に黒色の酸化鉄を残した状態の鋼材)上に塗装する場合、水系塗料は溶剤系塗料と比較して表面張力が高く濡れ広がりにくいため、鋼材との付着性が劣り、早期の剥離や赤錆が生じることがあった。 In particular, when painting on black steel (steel with black iron oxide remaining on the surface), which has microscopic irregularities on the surface, water-based paints have a higher surface tension than solvent-based paints and are less likely to wet and spread, resulting in poor adhesion to the steel and early peeling or red rust.
本発明は、黒皮鋼材を含む種々の基材に対して優れた付着性を有し、建機向け水性塗料として耐食性に優れた一液型水性塗料組成物を提供することを目的とする。 The present invention aims to provide a one-component water-based paint composition that has excellent adhesion to various substrates, including black steel, and has excellent corrosion resistance as a water-based paint for construction machinery.
本発明の目的は、下記によって達成された。 The object of the present invention has been achieved by the following:
1. 少なくとも、
(A)エポキシエステル樹脂、
(B)アクリル樹脂、および、
(C)乾性油または乾性油の重合物から選択される少なくとも一種の化合物、
とを含有する一液型水性塗料組成物。
2. 前記一液型水性塗料組成物の固形分中における前記(A)エポキシエステル樹脂の含有量が5~30質量%である前記1記載の一液型水性塗料組成物。
3. 前記一液型水性塗料組成物の固形分中における前記(C)乾性油または乾性油の重合物から選択される少なくとも一種の化合物の含有量が0.1~5.0質量%である前記1または2記載の一液型水性塗料組成物。
4. 前記(A)エポキシエステル樹脂が、ビニル変性エポキシエステル樹脂である前記1~3のいずれかに記載の一液型水性塗料組成物。
5. (D)酸化促進剤を含有する前記1~4のいずれかに記載の一液型水性塗料組成物。
