ANTICORROSIVE UNDERCOAT MATERIAL FOR STEEL MATERIAL
PROBLEM TO BE SOLVED: To provide an anticorrosive undercoat material for steel material maximumly utilizing chloride ion capture (absorption) function of nitrite type hydrocalumite, a method for anticorrosive undercoat for steel material and an anticorrosive steel material.SOLUTION: A water curable undercoat material excellent in steel material corrosive prevention and coatability by blending a re-emulsified shape powder resin and a thickener with a main components of cement water curable material, a fine aggregate and a nitrite type hydrocalumite. In a corrosion prevention method for under coating, intermediate coating and top coating the steel material, the undercoat material is used as an undercoat material, a weak solvent epoxy resin coating is used as an intermediate coating material and uniform undercoat layer is formed on the steel material without unevenness, an intermediate layer strongly adhered to the porous undercoat layer can be formed and, as the result outstanding corrosion prevention function can be added to the steel material.SELECTED DRAWING: Figure 1
【課題】亜硝酸型ハイドロカルマイトの塩化物イオン捕捉（吸着）機能を最大限に活かした、鋼材防食用下塗り材、鋼材防食塗装方法及び防食鋼材を提供する。【解決手段】セメント系水硬化材、細骨材、亜硝酸型ハイドロカルマイトの主要成分に、再乳化形粉末樹脂及び増粘剤を配合することにより、鋼材防食性に優れ、かつ塗装性に優れる水硬化性下塗り材とすることが出来た。また、鋼材に、下塗り、中塗り及び上塗り塗装する防食方法において、下塗り材として上記下塗り材を用い、中塗り材として弱溶剤エポキシ樹脂塗料を採用することにより、鋼材にムラなく均一な下塗り層を形成させ、かつ、多孔質の下塗り層に強固に密着した中塗り層を形成させることを可能にし、結果鋼材に卓越した防食機能を付与することを可能にした。【選択図】図１
