[0016] The preparation method of the plastic product of the present invention includes sequentially forming a copper layer, a nickel layer and a chromium layer on the surface of a plastic substrate, and then forming a ceramic layer on the chromium layer. The ceramic layer is a titanium nitride layer, a titanium carbide layer and One or more of the titanium carbonitride layers.
[0017] The copper layer, nickel layer, and chromium layer can be formed by various conventional methods, for example, can be formed by physical vapor deposition, or can be formed by electroplating.
[0018] From the perspective of the adhesion of the plating layer to the plastic substrate, the present invention preferably forms the copper layer, the nickel layer and the chromium layer by an electroplating method. The electroplating conditions only need to be such that the thickness of the formed copper layer is 5-15 microns, the thickness of the nickel layer is 5-30 microns, and the thickness of the chromi...
Example Embodiment
[0039] Example 1
[0040] This example illustrates the plastic product of the present invention and its preparation method.
[0041] The electroplating grade acrylonitrile-butadiene-styrene and polycarbonate composite plastic material (GE's C1200HF-GY7B080U LEXAN) is used as the raw material (the weight ratio of acrylonitrile-butadiene-styrene to polycarbonate is about 7: 3) Perform injection molding with an injection molding machine to obtain a plastic substrate.
[0042] The plastic substrate is processed in sequence as follows:
[0043] Degreasing → washing → surface adjustment → washing → roughening → washing → neutralization → washing → presoaking → washing → activation → washing → surface catalysis → washing → copper plating → washing → nickel plating → washing → nickel sealing → washing → chrome plating → Washing → drying
[0044] The degreasing is to scrub the surface of the plastic substrate with a degreasing liquid. The degreasing liquid is a CRP CLEANER produced by Hang...

[0069] Example 2
[0070] This example illustrates the plastic product of the present invention and its preparation method.
[0071] Using electroplating grade acrylonitrile-butadiene-styrene (LG's ABS MP-211) as raw material, injection molding is performed with an injection molding machine to obtain a plastic substrate.
[0072] The plastic substrate is processed in sequence according to the following procedures:
[0073] Degreasing → washing → surface adjustment → washing → roughening → washing → neutralization → washing → presoaking → washing → activation → washing → surface catalysis → washing → copper plating → washing → nickel plating → washing → nickel sealing → washing → chrome plating → Washing → drying
[0074] The degreasing is to scrub the surface of the plastic substrate with a degreasing liquid, the degreasing liquid is a CRP CLEANER produced by Hangzhou Ooye Technology Industrial Co., Ltd., the degreasing temperature can be 80°C, and the degreasing time is generally...
