Resin carbon steel joined body and method for producing the same

摘要

A resin carbon steel joined body having joining strength and a method for producing the joined body are provided. A method for producing a resin-carbon steel joined body according to the present invention includes a degreasing step of cleaning a carbon steel member with an alkaline solution, an acid treatment step of cleaning the carbon steel member with an acidic solution, and a carbon steel member. An activation treatment step in which a constant voltage or constant current is applied to the electrode by immersion in an alkaline solution, and a carbon steel member is used as an anode, and a predetermined current density is applied in an alkaline solution containing a triazine thiol derivative, and carbon A step of forming an anodized film having a thickness of 30 to 2000 nm on a steel member, a washing step of washing the carbon steel member having the anodized film formed with water, and a carbon steel member having the anodized film formed thereon; And insert-molding a thermoplastic or thermosetting resin.
