Embodiment Construction

[0017] see figure 1 , the method for the composite body 100 of metal and plastic according to a preferred embodiment of the present invention includes the following steps:

[0018] (1) Provide a metal base 11, and the material of the metal base 11 can be stainless steel, aluminum or aluminum alloy.

[0019] (2) The metal substrate 11 is subjected to conventional degreasing and degreasing treatment. The metal base 11 made of aluminum or aluminum alloy also needs to be treated with alkali bite or the like to remove the oxide impurity film on the surface of the metal base 11 .

[0020] (3) Performing surface treatment on the metal substrate 11 to form several nanopores on the surface of the metal substrate 11 , and the average pore diameter of the several nanopores is 30-60 nm.

[0021] When the material of the metal substrate 11 is aluminum or aluminum alloy, anodizing treatment can be used to form an aluminum oxide film on the surface of the metal substrate 11, and several na...

Abstract

The invention provides a preparation method of a metal and plastic composite body. The method comprises the following steps of: performing surface treatment on a supplied metal base body so as to form a plurality of nano holes in the surface of the metal base body, wherein the average aperture of the nano holes is 30nm-60nm; and heating the perforated metal base body, and applying pressure on a supplied plastic piece to combine the plastic piece with the metal base body. The method is simple and environmentally-friendly; and the bonding strength of metal and plastic of the composite body prepared by the method is high. The invention also provides the metal and plastic composite body prepared by the method.

Description

technical field [0001] The present invention relates to a preparation method of a metal-plastic composite and a composite obtained by the method. Background technique [0002] The preparation method of the composite body of metal and resin is usually as follows: firstly surface treatment of metal to form uneven hole structure on the metal surface; metal surface. However, when metal is put into injection molding equipment, it is prone to wear and scratches, which leads to lower product yield and is not conducive to the simplification of production. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide a method for preparing a composite of metal and plastic with a simple process. [0004] In addition, it is also necessary to provide a composite obtained by the above method. [0005] A method for preparing a composite of metal and plastic, comprising the steps of: [0006] Provide metal base; [0007] Surface treatment is performed on the metal su...
