Title:
WATER-BASED TREATMENT AGENT, ZINC-PLATED STEEL MATERIAL OR ZINC ALLOY-PLATED STEEL MATERIAL, AND COATED ZINC-PLATED STEEL MATERIAL OR COATED ZINC ALLOY-PLATED STEEL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/010571
Kind Code:
A1
Abstract:
The present invention provides a water-based treatment agent that imparts, even without including chromium, corrosion resistance, alkali resistance, acid resistance, and coating-film adhesiveness to a forming-processing section. Provided is a water-based treatment agent containing (A) a zirconium compound, (B) an epoxy resin, (C) a silanol group-containing compound represented by formula (I) and/or a condensate thereof:
XY(Z)nSi(OH)3-n ... (I),
(D) a phosphate compound, and (E) a quadrivalent vanadium compound, wherein, with respect to the mass in terms of Zr of the zirconium compound (A), the mass ratio [(B)/Zr] of the mass of the epoxy resin (B) is 0.7-1.5, the mass ratio [SiO2/Zr] of the mass in terms of SiO2 of the silanol group-containing compound and/or condensate thereof (C) is 0.15-1.5, the mass ratio [P/Zr] of the mass in terms of P of the phosphate compound (D) is 0.025-0.1, and the mass ratio [V/Zr] of the mass in terms of V of the quadrivalent vanadium compound (E) is 0.02-0.05.
