preparation example Construction

[0020] A method for preparing a metal-resin composite 100, comprising the steps of:

[0021] A shaped metal substrate 10 is provided, which can be any one of aluminum, aluminum alloy, titanium alloy, aluminum-magnesium alloy and zinc alloy.

[0022] The metal substrate 10 is degreased. The metal substrate 10 is immersed in a neutral metal cleaning agent with a concentration of 5-20g / L. The metal cleaning agent can be an aluminum alloy cleaning agent, a titanium alloy cleaning agent or a zinc alloy cleaning agent, and the temperature of the metal cleaning agent is kept at Clean the metal substrate 10 for 3-10 minutes under ultrasonic conditions at 40-75° C. to remove oil stains on the surface of the metal substrate 10 .

[0023] The degreased metal substrate 10 is dipped in alkaline solution for 2-5 minutes to remove the natural oxide layer on the surface of the metal substrate 10 . The concentration of the alkaline solution is 5-40g / L, and the alkaline solution can be any on...

Embodiment 1

[0035] In this embodiment, the material of the metal substrate 10 is an aluminum alloy substrate Al5052, and the material of the resin layer 40 is PBT.

[0036] Degrease, immerse the metal substrate 10 in a neutral aluminum alloy cleaning agent with a concentration of 25 g / L, keep the temperature of the aluminum alloy cleaning agent at 60° C., and clean under ultrasonic conditions for 6 minutes.

[0037] The degreased metal substrate 10 was immersed in an alkaline solution of NaOH with a concentration of 50 g / L for 0.5 min.

[0038] The metal substrate 10 bitten by the alkali is immersed in a nitric acid solution with a concentration of 150 g / L to peel off the black film, and the time for peeling off the black film is 60 seconds.

[0039] The metal substrate 10 that has been stripped of the black film is subjected to anodic oxidation treatment. The electrolytic solution for anodic oxidation is 300g / L sulfuric acid solution, the voltage is 13V, the temperature is 20°C, and the ...

Embodiment 2

[0044] In this embodiment, the material of the metal substrate 10 is aluminum-magnesium alloy, and the material of the resin layer 40 is PPS.

[0045] Degrease, immerse in a neutral aluminum alloy cleaning agent with a concentration of 25g / L, keep the temperature of the aluminum alloy cleaning agent at 60°C, and clean under ultrasonic conditions for 6 minutes.

[0046] The degreased metal substrate 10 was immersed in an alkaline NaOH solution with a concentration of 30 g / L for 1 min.

[0047] The metal substrate 10 bitten by the alkali is immersed in a nitric acid solution with a concentration of 150 g / L to peel off the black film, and the time for peeling off the black film is 60 seconds.

[0048]The metal substrate 10 with the black film peeled off is subjected to anodic oxidation treatment, the electrolytic solution for anodic oxidation is 100g / L sulfuric acid solution, the voltage is 13V, the temperature is 20°C, and the anodic oxidation time is 30min. The resulting anodi...

Abstract

The invention provides a method for preparing a composite of metal and resin. By immersing an anodized metal base material in a coupling agent, a coupling connection layer is formed on the surface of the anodized film and holes, so that the injection-molded resin layer It is combined with the coupling connection layer by chemical bonds, so that the resin layer and the metal substrate are combined by chemical bonds. Therefore, the resin layer on the surface of the metal substrate in the prepared composite is not easy to peel off, crack (crack) ), breakage, etc. In addition, the present invention also provides a composite body prepared by the above method, which composite body includes a metal substrate, an anodized film covering the surface of the metal substrate, a coupling connection layer bonded to the surface of the anodized film, and a coupling layer bonded to the coupling layer. The resin layer on the surface of the connection layer.

Description

technical field [0001] The invention relates to a method for preparing a composite of metal and resin and the composite obtained by the method. Background technique [0002] In recent years, the manufacturing requirements of portable electronic devices, automobiles and IT industry products have become more and more difficult. How to make products lighter, thinner and more functional has always been the goal of the industry. The weight is particularly important. The various material components of portable electronic devices, automobiles, and IT industry products can be bonded together effectively and quickly without taking up space, which can reduce the thickness of the product and improve the ability of signal transmission and reception. [0003] At present, there are many ways to combine metal and plastic materials, including adding a layer of adhesive between the two, or fixing them together mechanically, or firstly treating the metal surface with a special surface treatm...
