Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a non-chromium type aqueous surface-treating agent which is useful as a ground treating agent for providing a precoated metal material excellent in corrosion resistance, coating adhesiveness (coating primary adhesiveness and coating secondary adhesiveness in T bending test) and coin scratch resistance, or the like. SOLUTION: The aqueous surface-treating agent for an environmental-compatible type pre-coated metal material contains a silane coupling agent and/or the condensate of the silane coupling agent(A), a metal oxide sol (B), a metal compound (C), and a water-dispersible silica (D), wherein the metal compound (C) is at least one kind selected from compounds of V, W, Mo, Al, Sn, Nb, Hf, Y, Ho, Bi, La, Ce and Zn, the mass ratio of (B) to (A) is 1/50-10/1, the mass ratio of (C) to (A) is 1/1000-4/10, and the mass ratio of (D) to (A) is 1/50-10/1. A metal material and a non-chromium type precoated metal material each having a coating of the aqueous surface-treating agent thereon are also provided. COPYRIGHT: (C)2008,JPO&INPIT
