<p>The present invention provides an anti-corrosive plating steel sheet comprising: a steel sheet; one or more zinc alloy plated layers formed on the steel sheet; and an adhesive layer including one or more materials selected from a group consisting of Mn, Al, Si, Cr, Ni, Ti, Nb, and Mo, wherein the adhesive layer is laid between the steel sheet and a zinc alloy plated layer or between adjacent zinc alloy plated layers. In addition to this, the present invention provides a method for preparing an anti-corrosive plating steel sheet, comprising: a zinc alloy plated layer forming step; and an adhesive layer forming step. According to the present invention, a coating layer for applying flexibility is inserted to a space between brittle anti-corrosive plating layers, thereby allowing the preparation of an anti-corrosive plating steel sheet having improved adhesion for anti-corrosive plating coating. In addition to this, the anti-corrosive plating steel sheet can go through high-speed processing by securing adhesion even when the adhesive layer is thin.</p> |
