METHOD FOR PRODUCING METAL-RESIN COMPLEX

摘要

Provided is a metal-resin complex in which a metal alloy and a resin composition that are heterogeneous materials are integrated with each other, and more particularly, a method for producing a metal-resin complex capable of improving bonding strength by producing a metal alloy having a more uniform etching surface using an alkaline aqueous solution to which a chelating agent is added and an acid aqueous solution to which the chelating agent and an amic acid are added, and injection-molding the resin composition by using the produced metal alloy.

主权项

1. A method for producing a metal-resin complex comprising:
preparing a surface-etched metal alloy material; and injection-molding a resin composition on a surface of the etched metal alloy material so that the metal alloy material and the resin composition are integrated with each other, wherein the preparing of the surface-etched metal alloy material includes: (i) a primary treatment process of treating the metal alloy material with an alkaline aqueous solution to which a chelating agent is added; and (ii) a secondary treatment process of etching the metal alloy material with an acid aqueous solution to which the chelating agent and an amic acid are added.
