Chrome free composition for surface treating metal and surface-treated metal sheet

The present invention relates to a conductive, corrosion-resistant, alkali metal and high-temperature moisture resistance is excellent and also not containing chromium having a coating not containing chromium surface treatment composition and surface-treated steel sheet. The surface treatment composition comprises i) a vinyl based binder resin is a corrosion-resistant inorganic composite; ii) an acrylic binder resin of the corrosion resistance inorganic composite; And iii) and a solvent, and 10 to 70% by weight of the amount of the total solid content of the vinyl based binder resin and 15 to 75% by weight of the amount of the total solid content of the acrylic binder resin, wherein the corrosion-resistant inorganic material is 3 in the total solid content to 25 present in a weight%. Zinc-plated steel sheet, the surface treatment solution, the Cr-free, resin-coated steel sheet, the steel sheet within the fingerprint, the conductive
