摘要:
A surface-treated steel sheet is disclosed, including a zinc based plated steel sheet having thereon a surface-treated film containing titanium, nickel, aluminum and fluorine and having a film thickness of from 0.05 to 1.0 μm, the surface-treated film having a titanium deposition amount of from 0.01 to 0.5 g/m2 and containing from 0.01 to 5 parts by mass of nickel, from 0.1 to 25 parts by mass of aluminum and from 1 to 500 parts by mass of fluorine relative to 100 parts by mass of titanium. This surface-treated steel sheet does not contain hexavalent chromium in the film thereof at all and has excellent heat discoloration resistance, corrosion resistance and resistance to blackening.

摘要:
The invention is to provide a surface-treated steel sheet of good white rust resistance with no chromium in its surface treatment film, and it has realized a surface-treated steel sheet of higher-level corrosion resistance by forming a reaction layer of plating metal with a barrier layer effective for anticorrosion not in a two-layered film but in a single-layered film. The surface-treated steel sheet is fabricated by applying a surface-treating composition that contains: (a) a water-dispersible resin and/or a water-soluble resin obtained through reaction of an epoxy group-containing resin (A) with an active hydrogen-containing compound (B) a part or all of which is an active hydrogen-containing hydrazine derivative and preferably with a hydrophilic organic component (C), (b) a silane coupling agent, (c) a phosphoric acid and/or a hexafluoro-metal acid, and (d) preferably an aqueous dispersion of an urethane resin, to a zinc-plated or aluminium-plated steel sheet followed by drying it to form thereon a surface treatment film having a thickness of from 0.02 to 5 μm. Regarding its film structure, the surface treatment film comprises an amorphous compound layer containing P, Zn and/or Al, and O, and an overlying organic resin matrix layer where the matrix is a hydrazine derivative-modified epoxy group-containing resin or the epoxy group-containing resin and an urethane resin.
