preparation example Construction

[0016] The preparation method of the plastic product described in the present invention comprises sequentially forming a copper layer, a nickel layer and a chromium layer on the surface of the plastic substrate, and then forming a ceramic layer on the chromium layer, and the ceramic layer is a titanium nitride layer, a titanium carbide layer and One or several layers in the titanium carbonitride layer.

[0017] The copper layer, nickel layer and chromium layer can be formed by various conventional methods, such as physical vapor deposition or electroplating.

[0018] From the viewpoint of adhesion between the plating layer and the plastic substrate, the copper layer, the nickel layer and the chromium layer are preferably formed by electroplating in the present invention. The conditions of the electroplating are as long as 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 chromium layer is 5-30 ...

Embodiment 1

[0040] This example illustrates the plastic product of the present invention and its preparation method.

[0041] Use electroplating grade acrylonitrile-butadiene-styrene and polycarbonate composite plastic material (GE's C1200HF-GY7B080U LEXAN) as 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 base material.

[0042] The plastic substrate is processed in turn according to the following procedures:

[0043] Degreasing→water washing→surface adjustment→water washing→roughening→water washing→neutralization→water washing→presoaking→water washing→activation→water washing→surface catalysis→water washing→copper plating→water washing→nickel plating→water washing→nickel sealing→water 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 CRP CLEAN...

Embodiment 2

[0070] This example illustrates the plastic product of the present invention and its preparation method.

[0071] Electroplating grade acrylonitrile-butadiene-styrene (LG's ABS MP-211) is used as a raw material, and injection molding is performed by an injection molding machine to obtain a plastic substrate.

[0072] The plastic substrate is processed in turn according to the following procedures:

[0073] Degreasing→water washing→surface adjustment→water washing→roughening→water washing→neutralization→water washing→presoaking→water washing→activation→water washing→surface catalysis→water washing→copper plating→water washing→nickel plating→water washing→nickel sealing→water 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 CRP CLEANER produced by Hangzhou Aoye Technology Industry Co., Ltd. The degreasing temperature can be 80° C., and the degreasing time is gener...

Abstract

The invention relates to a plastic product, comprising plastic substrate. The plastic product is characterized in that the product also comprises a copper coating, a nickel coating, a chrome coating and a ceramic coating from the surface of the plastic substrate to the outside in sequence; the ceramic coating is one or more layer of titanium nitride, titanium carbide and titanium carbonitride. The plastic product made by the invention has excellent wearing resistance, the film formed on the surface of the plastic product has excellent adhesiveness, and the plastic product that is obtained finally also has ceramic texture and good handfeel.

Description

technical field [0001] The invention relates to a plastic product and a preparation method thereof. Background technique [0002] At present, raw materials for preparing plastic products usually include thermoplastics and thermosetting plastics, such as acrylonitrile-butadiene-styrene (ABS), polypropylene (PP), nylon (PA), polytetrafluoroethylene (PTFE), polyoxymethylene (POM), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PST), polysulfone (PSF), polyphenylene oxide (PPO), polyethylene terephthalate One or more of polyester (PET), polycarbonate (PC) and polymethyl methacrylate (PMMA); the thermosetting plastic can be, for example, phenolic plastic and / or epoxy plastic. In addition, the plastic base material may also include various additives commonly used in plastic base materials to improve the performance of the plastic base material, for example, glass fibers may be added to increase the strength of the plastic base material. [0003] Plastic products made ...
