Embodiment 1

[0026] The manufacturing process of electrochemical deposition products using PCVD coloring includes implementing the following steps in sequence:

[0027] 1) Thermoforming plastic raw materials to form a plastic matrix;

[0028] 2) Chemical deposition is carried out on the surface of the plastic substrate to form an electroless nickel coating;

[0029] 3) Electrochemical deposition is carried out on the surface of the chemical nickel coating to form a Watt nickel coating;

[0030] 4) Electrochemical deposition is carried out on the surface of the Watt nickel coating to form a copper coating, and the thickness of the copper coating remains at about 35um;

[0031] 5) Electrochemical deposition is carried out on the surface of the copper coating to form a multi-layer nickel coating consisting of a semi-gloss nickel layer, a light nickel layer and a sealing nickel layer. The thickness of the multi-layer nickel coating remains at about 20um, and the number of micropores in the se...

Abstract

The invention discloses a manufacturing technology using PCVD coloring of an electrochemical deposition product . The manufacturing technology comprises the following steps: arranging a metal coatingon a plastic base material through electrochemical deposition to form an electrochemical deposition original piece, and then, carrying out PCVD coloring on the electrochemical deposition original piece to obtain the PCVD colored electrochemical deposition product, so that the binding force of a wet process plated metal layer and a paint spraying film layer is enhanced, the PCVD coloring technologyis combined with the electrochemical deposition original piece to improve the functionality of the PCVD colored product, and at the same time, the metal appearance and the cold touch of an electrochemical deposition layer are completely kept, and the electrochemical deposition layer is suitable for serving as high-end vehicle model interior trimming.

Description

technical field [0001] The invention relates to the technical field of plastic surface treatment, in particular to the surface treatment technology combining PCVD and electrochemical deposition. Background technique [0002] The diversification and fashion of interior color matching is the development trend of the future automobile field. There are mainly two traditional processes for color metallization of automotive interior parts: PVD aluminum layer + intermediate paint toning; and toning metallic paint. The disadvantage of these two processes is that the outermost layer needs topcoat protection, resulting in a lower metallic texture of the product. However, since the metallic paint is realized by adding silver powder, the appearance of the finished product has a grainy feel, and it is difficult to approach the color of the light chrome of the electroplated part. [0003] Plastic color metallization can also be realized by using PCVD process. The PCVD process is plasma...
