Abstract
Official abstract text for this publication.
A surface treatment liquid contains a resin emulsion that contains a cationic urethane resin emulsion and/or a nonionic acrylic resin emulsion, a tetraalkoxysilane, at least one silane coupling agent (c) that contains at least one reactive functional group selected from active hydrogen-containing amino group, an epoxy group, a mercapto group, and a methacryloxy group, a chelating agent (d), a vanadic acid compound (e), a titanium compound (f), and water in a specific ratio. The surface treatment liquid has a pH of 3 to 6. The surface treatment liquid is applied to a surface of a zinc-based metal coated steel sheet and dried by heating to form a first layer. Next, a surface treatment liquid containing an organic resin is applied to a surface of the first layer and dried by heating to form a second layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A zinc-based metal coated steel sheet comprising: a surface film arranged on a surface of a zinc-based metal coated layer, the surface film having a two-layer structure including a first layer and a second layer, wherein the first layer is formed by applying a surface treatment liquid (A) for a zinc-based metal coated steel sheet to the surface of the zinc-based metal coated layer and performing drying by heating, the surface treatment liquid (A) con…
