Embodiment Construction

[0016] see figure 1 , the preparation method of the metal-plastic composite 100 in a preferred embodiment of the present invention includes the following steps:

[0017] (1) Provide aluminum or aluminum alloy substrate 11.

[0018] (2) Perform conventional degreasing and degreasing treatment on the aluminum or aluminum alloy substrate 11 . Alcohol, acetone, and water are used to clean the aluminum or aluminum alloy substrate 11 in order to remove surface dirt.

[0019] (3) Soaking and corroding the aluminum or aluminum alloy substrate 11 with a cleaning solution. The cleaning solution contains 18% nitric acid (HNO 3 ) and 10% hydrofluoric acid (HF). The immersion corrosion can remove the oxide film layer formed on the surface of the aluminum or aluminum alloy substrate 11 .

[0020] (4) Electrochemically corroding the aluminum or aluminum alloy substrate 11 after immersion corrosion, so that the surface of the aluminum or aluminum alloy substrate 11 is corroded to form a ...

Abstract

The invention provides a manufacturing method of a metal and plastic combination body. The method comprises the steps that an aluminum or aluminum alloy base body is provided; a solution is used for soaking and corroding of the aluminum or aluminum alloy base body; the soaked and corroded aluminum or aluminum alloy base body is subjected to electrochemistry corrosion, water solution of sodium bicarbonate is used as electrolyte, a multi-hole layer which is provided with a plurality of corrosion holes is formed on the surface of the aluminum or aluminum alloy base body, the plurality of corrosion holes comprise holes with nanoscale diameters and holes with micrometer-scale diameters, the corrosion holes are communicated in a mutual-staggering mode so that a three-dimension network multi-hole structure of the multi-hole layer is formed; fused plastic is injected on the surface of the multi-hole layer, and the metal and plastic combination body is formed. The method is simple in technology and environmental-friendly, and the combination body manufactured with the method is high in combining strength of metal and the plastic. The invention further provides the metal and plastic combination body manufactured with the method.

Description

technical field [0001] The invention relates to a method for preparing a composite of metal and plastic and the composite obtained by the method. Background technique [0002] At present, the combination of aluminum alloy and plastic parts still adopts a large number of adhesive methods. In order to improve the bonding force of the adhesive, in addition to the selection of high-performance adhesive, the surface treatment of aluminum alloy workpieces, such as anodic oxidation, is often carried out. Aluminum alloy can form a layer of anodic oxidation film on its surface after anodic oxidation process. This layer of anodic oxidation film is porous, and the pore size is usually nano-scale. However, the binding force between the aluminum alloy and the plastic parts prepared by this method is not strong, which limits its further application. Contents of the invention [0003] In view of this, it is necessary to provide a method for preparing a composite body in which an alumin...
