Title:
SURFACE TREATMENT MEMBRANE, METAL SURFACE TREATMENT AGENT AND METAL SURFACE TREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2011/093282
Kind Code:
A1
Abstract:
Provided are a surface treatment membrane and a metal surface treatment agent which are not susceptible to peeling of the laminate film or resin coating film, even if molding is carried out subsequent to a resin film being laminated or resin-coated onto the surface of a metal material. Specifically provided is a surface treatment membrane which is formed by application to the surface of a metal material. The mass ratio of nitrogen to carbon (N/C) contained in said surface treatment membrane falls within the range 0.005 to 0.5, and the mass ratio of the total metal elements selected from Cr (III), Zr, Ti, V, Nb, Mo, W and Ce to carbon (TM/C) falls within the range of 0.01 to 1.3. This surface treatment membrane contains a first water-based resin such as urethane resin, a second water-based resin such as a polyolefin resin, and a water-soluble metal compound containing a metal element such as Cr (III), and the membrane is preferably formed by applying the coating with a metal surface treatment agent wherein the first water-based resin and/or the second water-based resin contains a nitrogen-containing functional group.
