Problems solved by technology

However, due to the strong corrosiveness of the chemical corrosion solution or electrochemical corrosion electrolyte to the stainless steel substrate itself, it will cause corrosion of the non-injection area of ​​the stainless steel product, especially the corrosion of the appearance surface, so it must be shielded and protected before treatment, or It is to add polishing or CNC machine tools (CNC) after the injection molding is completed, and the process is complicated, which limits its scope of use. At the same time, the composite of stainless steel and resin prepared by this corrosion method, the combination of stainless steel and resin is not ideal. Effect

Abstract

The invention discloses a stainless steel-resin composite. The composite comprises a stainless steel substrate (1), an aluminum film layer (3), a anode oxide film (4) and a resin layer (5), wherein the aluminum film layer (3) is disposed on at least partial surface of the stainless steel substrate (1); and the anode oxide film (4) and the resin layer (5) are laminated on the aluminum film layer (3) in sequence. The invention also provides a preparation method of the stainless steel-resin composite. The stainless steel-resin composite provided by the invention has a strong binding force between the stainless steel substrate and the resin layer. The method provided by the invention is environment-friendly. The preparation process is simple. The method provided by the invention can be universally applied on metals such as the stainless steel with relatively stable properties, and can compound the metal and the resin on metals with complex structures.

Description

technical field [0001] The invention relates to a composite body of stainless steel and resin and a preparation method thereof, in particular to a composite body with strong binding force between stainless steel and resin and a preparation method of the composite body. Background technique [0002] The technology of integrating metal and resin is required in a wide range of industries such as automobiles, household electrical products, industrial equipment and other parts manufacturing. [0003] At present, there are two main methods of combining stainless steel and resin. One is to use adhesives to combine the two with stainless steel and formed resin through chemical adhesives respectively; the other is to chemically bond the stainless steel surface. Or electrochemical etching to create holes on the surface of stainless steel, through which holes are combined with plastic injection molding. [0004] Among them, although the method of using an adhesive can prepare a compos...
