Abstract:
(EN) [Problem] To provide a surface-treated steel sheet with excellent blushing resistance and corrosion resistance. [Solution] A surface-treated steel sheet with a steel sheet, a zinc-containing plating layer formed on a surface of the steel sheet, and a coating formed on the plating layer, wherein: the coating comprises a resin component containing resin particles made of a polyurethane resin of 20 nm to 200 nm average particle size, and P, Ti, V and Si; the coating 3 comprises 2.5 mass% to 7.5 mass% of P; the area ratio of the resin component in a cross-section of the coating is 35% to 80%; the resin particles are dispersed in the coating; and the maximum distance between centers of gravity of the resin particles is not more than 3.0 times the average particle size of the resin particles.
(FR) Le problème décrit par la présente invention est de fournir une tôle d'acier traitée en surface présentant une excellente résistance au voilage et une excellente résistance à la corrosion. La solution selon l'invention porte sur une tôle d'acier traitée en surface avec une tôle d'acier, une couche de placage contenant du zinc formée sur une surface de la tôle d'acier, et un revêtement formé sur la couche de placage, le revêtement comprenant un composant résine contenant des particules de résine constituées d'une résine de polyuréthane d'une taille de particule moyenne de 20 nm à 200 nm, et du P, du Ti, du V et du Si ; le revêtement (3) comprenant de 2,5 % en masse à 7,5 % en masse de P ; le rapport surfacique du composant résine dans une section transversale du revêtement étant de 35 % à 80 % ; les particules de résine étant dispersées dans le revêtement ; et la distance maximale entre les centres de gravité des particules de résine n'étant pas supérieure à 3,0 fois la taille de particule moyenne des particules de résine.
