Water-based metal material surface treatment agent, surface-treated metal material and surface treatment method

摘要

In one molecule, the invention functions represented by (alkyl group, represents hydroxyl or alkoxy groups, one an alkoxy group, at least ^{R 3} and ^R 1, ^{R 2)} formula -SiR ¹ R ² R ³ and 2 or more, and one or more (b) a hydrophilic functional group selected from a hydroxyl group, an amino group, a carboxyl group, a phosphoric acid group, a phosphonic acid group, a sulfonic group, an amide group and a polyoxyethylene chain (a) group A content, and blending the organic silicon compound is 100 to 10,000 molecular weight functional group (b) per, an organic polymer selected from urethane resins, epoxy resins, acrylic resins, phenolic resins, polyolefin resins and polyester resins water-based metal surface treatment agent comprising Te, on the treated metal material and processing method. Excellent corrosion resistance to the metal material surface, adhesion, as well as the treatment agent, can form a film having both the alkali resistance and acid resistance.
