Embodiment 1

[0030] The preparation method of the metal-resin composite body includes the following steps: metal workpiece—oil removal and degreasing treatment—surface layer treatment for metal natural oxide removal—microporous treatment—nitrogen atom adsorption treatment—water washing and drying treatment—injection molding treatment—obtaining the metal resin composite body.

[0031] Specifically, degreasing is as follows: Ultrasonic treatment of CNC or punched metal workpieces at 40°C-60°C for 3-5 minutes, the ultrasonic power is 2-2.6KW, and the concentration of the ultrasonic liquid is 100-300g / L acid, alkali or organic solvent. This step is mainly for degreasing and degreasing. The ultrasonic power and concentration of ultrasonic liquid can remove as much grease as possible on the surface of the workpiece without corroding the metal workpiece body to prepare for the next step. The metal workpiece can be various metals such as copper, steel, titanium, magnesium, etc., or various metal ...

[0039] The preparation method of the metal-resin composite body includes the following steps: metal workpiece—oil removal and degreasing treatment—surface treatment for removing metal natural oxide—anodic oxidation treatment—microporous treatment—washing and drying treatment—injection molding treatment—obtaining the metal resin composite body.

[0040] Specifically, degreasing is as follows: Ultrasonic treatment of CNC or punched metal workpieces at 40°C-60°C for 3-5 minutes, the ultrasonic power is 2-2.6KW, and the concentration of the ultrasonic liquid is 100-300g / L acid, alkali or organic solvent. This step is mainly for degreasing and degreasing. The ultrasonic power and concentration of ultrasonic liquid can remove as much grease as possible on the surface of the workpiece without corroding the metal workpiece body to prepare for the next step. The metal workpiece can be various metals such as copper, steel, titanium, magnesium, etc., or various metal alloys, and aluminu...

Abstract

The invention relates to the technical field of material preparation, and particularly relates to a preparation method of a metal-resin composite and the metal-resin composite. The preparation method comprises the step of oil removing and degreasing treatment, native metal oxide surface layer removing treatment, secondary etching treatment, washing with water, drying treatment, and resin injection molding on a metal workpiece in sequence, so as to obtain the metal-resin composite. The composite has excellent characteristics of metal force and resin, metal and the resin can be firmly bonded, and experiments indicate that under relatively large action, even if the resin is broken off, the resin and the metal are still firmly bonded.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a method for preparing a metal-resin composite and the resulting metal-resin composite. Background technique [0002] A composite material is a heterogeneous solid material that combines two or more substances with different physical and chemical properties. The first advantage of composite materials is the composite effect of their properties, that is, several different properties are combined in one material to make them play a role at the same time. The second is that the most suitable composite material can be designed according to the requirements of use, that is, designability. Among them, the metal-resin composite material has a metal decorative layer and a resin layer as a supporting layer, and the supporting layer is connected to the decorative layer by spraying, injection molding or stamping, and has a small weight and a high-quality appearance; Therefore, it is wid...
