[0037] refer to figure 1 , according to an embodiment of the present invention, the preparation method of the composite material includes the following steps:
[0038] Surface laser treatment of metal substrates to form fine holes;
[0039] Surface treatment of metal substrates with fine pores with metal wetting agents;
[0040] Injection molding the metal substrate and plastic treated with metal wetting agent to obtain a composite material integrating metal and plastic;
[0041] Wherein, the metal wetting agent contains an organic acid agent for improving the difference in surface tension coefficient between the metal substrate and the plastic.
[0042] The materials used in carrying out the method of the present invention are as follows.
[0043] 1. Metal: The metal can be a metal substrate formed by machining, and can be but not limited to one of stainless steel, titanium alloy, aluminum alloy, magnesium alloy and copper alloy.
[0044] 2. Plastic: said plastic can be b...
Embodiment 1
[0063] Metal wetting agents include the following components:
[0064] In 1000 parts of solvent (wherein water 700 parts, ethanol 300 parts), be furnished with the raw material component of following weight ratio:
[0065] 1) 105 parts of concentrated hydrochloric acid;
[0066] 2) 200 parts of organic acids, including: 120 parts of maleic acid and 80 parts of malic acid.
[0067] The preparation method of composite material comprises the following steps:
[0068] 1) Provide a metal substrate formed by machining, mainly involving one of stainless steel, titanium alloy, aluminum alloy, magnesium alloy and copper alloy.
[0069] 2) Carry out chemical degreasing treatment on the metal substrate with a degreasing agent sold on the market to remove oil stains on the metal surface; the chemical degreasing temperature is 85°C, and the degreasing time depends on the specific degreasing effect.
[0070] 3) Perform surface ultraviolet laser treatment on the degreasing metal substrate...
