摘要: Provided are a chromium-free passivated and film-covered tinned plate, a passivation treatment solution for manufacturing a passivation film, and a manufacturing method for a tinned plate. The chromium-free passivated and film-covered tinned plate comprises a tinned plate and a polyester film laminated on a surface of the tinned plate. The tinned plate comprises a substrate, a tin coating and a passivation film covering a surface of the tin coating. The passivation film does not contain chromium, and contains 2.0-20 mg/m2 of zinc and 10-60 mg/m2 of silicon. A solvent in the passivation treatment solution is water, and the solution contains 0.5-5.0 wt% of a zinc salt and 10-30 wt% of an organosiloxane or a polysiloxane. The manufacturing method for the tinned plate comprises: (1) electrotinning a steel substrate to form a tin coating; (2) subjecting the steel substrate having the tin coating to a soft melting treatment to form an iron-tin alloy layer; (3) spray-coating a passivation treatment solution to form a tinned plate having a passivation film; (4) squeeze-drying the tinned plate; (5) hot air drying; and (6) thermally laminating a polyester film onto a surface of the surface-treated tinned plate.
