Strong combination method of metal material and plastic material

Abstract

The invention discloses a treatment method of forming nano holes on the surface of an aluminum alloy and a strong combination method of a metal material and a plastic material. The treatment method comprises the following steps of: S1, selecting a workpiece and mounting the workpiece on a rack, S2, performing preliminary treatment: washing the workpiece with water, removing dust or residual fragments after machining from the surface of the workpiece, S3, performing hole preforming treatment-chemical corrosion, S4, performing hole forming treatment-electrolysis, S5, performing post treatment, and S6, performing soaking treatment to accomplish an entire experiment. The chemical corrosion is adopted during the hole preforming treatment; electrochemical corrosion is adopted during the hole forming treatment; the method is applicable to aluminum alloy materials with different strength; for example, uniform nanoscale holes are formed on the surface of a harder aluminum alloy AL6061-T6; the soaking treatment is performed after the hole forming treatment; the aluminum alloy materials are soaked in an amine compound; and the bonding degree between the aluminum alloy materials and a glue solution can be increased.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to a method for strongly combining metal materials and plastic materials. Background technique [0002] Nano-injection molding technology, referred to as NMT (Nano Molding Technology), is to directly inject plastic onto the metal surface after nano-treatment, so that the metal and plastic can be integrally formed. This technology is different from the traditional adhesion technology. The adhesion strength is greatly enhanced, which not only improves the metal performance of the product, but also takes into account the texture of the metal appearance, and can also simplify the design of product mechanical components, making the product lighter, thinner, shorter and smaller. NMT can be used in industrial and consumer electronics, power batteries, mobile communications, biomedical, aerospace, auto parts, and even military products. Its material properties are mainly m...
