    摘要: An aqueous surface-treatment liquid is a treatment liquid containing a water-soluble zirconium compound, water-dispersive particulate silica, a silane coupling agent, a vanadic acid compound, a phosphoric acid compound, a nickel compound, and an acrylic resin emulsion in particular proportions. A surface-treated galvanized steel sheet produced using the treatment liquid is a galvanized steel sheet having a surface-treatment coating on a surface thereof, and the coating contains a zirconium compound, particulate silica, a silane-coupling-agent-derived component, a vanadic acid compound, a phosphoric acid compound, a nickel compound, and an acrylic resin in particular proportions. The amount of coating on a zirconium basis is 10 to 200 mg/m2. This surface-treated galvanized steel sheet is chromate-free and has superior flat-portion corrosion resistance, blackening resistance, and appearance and corrosion resistance after press forming.

    摘要: A surface-treated galvanized steel sheet includes a steel sheet, a zinc coating disposed on the steel sheet, and a film disposed on the zinc coating. The film has a thickness in the range of 0.01 to 3 μm and contains certain amounts of resin compound having a particular chemical structure, cationic urethane resin, vanadium compound, zirconium compound, compound having a phosphate group, and acid compound. The surface-treated galvanized steel sheet contains no hexavalent chromium in the film and is excellent in terms of corrosion resistance, alkali resistance, and solvent resistance.
