Abstract:
(EN) Disclosed are: a chromium-free surface-treating agent which can form, on the surface of a metallic material, a coating film having excellent corrosion resistance at a bent part in a steel sheet, excellent solvent resistance and excellent coating properties after alkali degreasing and has excellent storage stability when prepared in the form of a one-part preparation; a process for manufacturing a plated steel sheet using the surface-treating agent; and a plated steel sheet. Specifically disclosed are: a surface-treating agent characterized by comprising a resin compound having a specific bisphenol skeleton, a cationic urethane resin emulsion, a silane coupling agent, an organic titanium chelate compound, a tetravalent vanadyl compound and water in a specified proportion and having a pH value of 4 to 5; a process for manufacturing a plated steel sheet using the surface-treating agent; and a plated steel sheet.
(FR) L'invention concerne: un agent de traitement de surface sans chrome susceptible de former, sur la surface d'un matériau métallique, un film de revêtement présentant une résistance à la corrosion excellente au niveau d'une partie pliée dans une tôle d'acier, une résistance aux solvants excellente et des propriétés de revêtement excellentes après dégraissage alcalin et présente une stabilité au stockage excellente lorsqu'il est préparé sous la forme d'une préparation monobloc. L'invention concerne en outre un procédé de fabrication de tôle d'acier plaquée utilisant l'agent de traitement de surface. Elle concerne également une tôle d'acier plaquée. Plus précisément, l'invention concerne: un agent de traitement de surface qui se caractérise en ce qu'il comprend un composé de résine présentant un squelette bisphénol spécifique, une émulsion de résine uréthanne cationique, un agent de couplage silane, un composé chélaté de titane organique, un composé de vanadyle tétravalent et de l'eau dans une proportion spécifiée et qui a une valeur pH comprise entre 4 et 5. L'invention concerne enfin un procédé de fabrication de tôle d'acier plaquée utilisant l'agent de traitement de surface, ainsi qu'une tôle d'acier plaquée.
