CONVERSION-COATED METAL PLATE FOR NON-CONDENSED THERMOPLASTIC RESIN BONDING, SURFACE-TREATED METAL PLATE FOR NON-CONDENSED THERMOPLASTIC RESIN BONDING, COMPOSITE MEMBER, AND METHOD FOR PRODUCING CONVERSION-COATED METAL PLATE FOR NON-CONDENSED THERMOPLASTIC RESIN BONDING

摘要

According to one aspect of the present invention, there is provided a chemical conversion coated metal sheet for non-condensed thermoplastic resin bonding, the chemical conversion coated metal sheet including a metal substrate and a chemical conversion coating film disposed on at least one surface of the metal substrate, in which the chemical conversion coating film is obtained by coating the metal substrate with a coating liquid that contains an ethylene-acrylic acid copolymer, colloidal silica, and a silane coupling agent. The ethylene-acrylic acid copolymer has an acrylic acid content of 10 mass% or more and a melt flow rate of 80g/10min or less.
