Japanese Patent JP6964809

Kind Code:

B2

Abstract:

To provide a metal-resin bonded article that is capable of stably retaining a sufficient bonding strength for a long period of time, and a method for producing the same. A metal-resin bonded article including a composite laminate including a metal base material having laminated thereon one layer or plural layers of a resin coating layer, and a resin material bonded and integrated thereto, the resin coating layer being laminated on a surface-treated surface of the metal base material, at least one layer of the resin coating layer containing a resin composition containing a linear chain polymer having a linear polymer structure polymerized on the metal base material, a bonding strength between the composite laminate and the resin material satisfying the following condition 1, and an adhesion force between the metal base material and the resin coating layer satisfying the following condition 2: (condition 1) a value evaluated by a tensile shear test according to the evaluation methods for the adhesion interface performance in plastic-metal assemblies of ISO 19095, after retaining the composite laminate and the resin material having been bonded and integrated to each other, under ordinary temperature and ordinary humidity for 24 to 48 hours, being 10 MPa or more, (condition 2) values evaluated according to the crosscut test of JIS K5600_5_6, after retaining the composite laminate having been produced, under ordinary temperature and ordinary humidity for 24 to 48 hours, and after immersing the composite laminate having been produced, in warm water at 60°C for 24 hours, being both 0.
