Abstract
The present disclosure relates to a method for preparing a metal-polymer resin composite with excellent bonding strength and bonding uniformity. The method includes a pretreatment step (S1) of etching a metal member, an electrolysis process step (S2) of forming an adhesive coating layer on a surface of the pretreated metal member, a drying step (S3) of drying the metal member with the adhesive coating layer formed on the surface, and an injection-molding process step (S4) of bonding a polymer resin to the dried metal member, and the electrolysis process is performed in an electrolyte solution containing a sulfur-containing compound and a metal chelate compound.
Claims13
A method for preparing a metal-polymer resin composite, the method comprising:
- a pretreatment step (S1) of etching a metal member, which is one or more selected from a group consisting of copper, a copper clad, and a copper alloy;
- an electrolysis process step (S2) of forming an adhesive coating layer on a surface of the pretreated metal member;
- a drying step (S3) of drying the metal member with the adhesive coating layer formed on the surface;
- and
- an injection-molding process step (S4) of bonding a polymer resin to the dried metal member,
- wherein the electrolysis process is performed in an electrolyte solution containing a sulfur-containing compound and a metal chelate compound,
- wherein the injection-molding process step (S4) is performed by preheating the metal member to an injection-molding temperature and then directly injection-molding the polymer resin onto the preheated metal member, and
- wherein the electrolyte solution is prepared by mixing 5 g to 500 g of the sulfur-containing compound and 1 g to 100 g of the metal chelate compound for each 1 L of distilled water.
