INSTRUCTIONS: [Technical Field of the Invention] The present invention relates to a method for producing a three-dimensional visual effect of plastic plating, and more particularly to a processing method of two or more times after plating on a surface of a plastic material. [Prior Art] Generally, plastic materials are widely used in daily necessities, even engineering plastics, due to their low electrical conductivity, light weight, chemical stability, _ impact resistance, transparent wear resistance, easy forming and coloring, and low cost. It can be used in the industry for its excellent strengthening properties, such as PET (polyethylene terephthalate), HDpE (high density polyethylene), PVC (polyvinyl chloride), LDPE (low density polyethylene), PP (polypropylene), PS (polystyrene), ABS are polymers of A (Acryl〇nitrile acrylonitrile), B (Butadiene butadiene), S (Styrene styrene), etc. Polyethylene (PE), polyethylene (IV), polypropylene (pp) or polystyrene (PS), ABS, ABS + PC composite materials are used. In particular, many electronic products are now available, such as computer cases, mobile phone panels, etc. Because plastics have the advantages of the first few, they are widely used as materials, and because of the red interior design and functions of electronic products, the appearance is dazzling. And the eye-catching is also the consumer Wei, so many of the material of the electronic material silk has metallic luster, rust, anti-wear, improve conductivity, run-up, strength, miscellaneous, weather resistance, etc. 'Therefore, it will be used on the exterior. Electroplating to paint. . It is the process of 'electiOplating', which is basically an eleCtr〇deposition process, which uses an electrode (el with de) to flow through the electricity 5 200806821, so that the metal adheres to the surface of the object, but the plastic is generally It is not easy to conduct electricity, and = this is chemically, after the surface of ABS is reduced, a layer of conductor is attached to make it conductive. For example, as shown in the announcement (Report) of the patent application for the "Plastic Surface Plating Process", it mainly reveals that the plastic surface is electrically and suitable for forming on the surface of the plastic component - the multiple metal layer, the plastic surface The electro-mineral process comprises at least the following steps: (a) spraying-the surfactant on the surface of the plastic component, and (8) forming a chemical copper layer on the plastic-rubber component through the interface activity by chemical plating. Riding a sprayed surface; (4) forming a chemical nickel layer on the surface of the chemical copper layer by chemical electrowinning; (4) adjusting the material properties of the surface of the plastic component such that the surface of the plastic component has a relatively negative charge; (4) forming an electroplated copper layer on the surface of the electroless nickel layer by electrolytic plating; (forming an electroplated nickel layer on the surface of the electroplated copper layer by electroplating; and (g) electrolyzing the electric bond Forming an electrochromic chrome layer on the surface of the electroplated nickel layer. However, the prior art described above is only disclosed for the electroplating process, and the general electroplated material is usually not metallic after it has a metallic luster. This can be used for products such as 3 C products, such as computers, communications (c_nicati〇n), and consumer electronics (Consumer Electronics), often requiring text, numbers, symbols, colors, etc. to mark or achieve eye-catching, Therefore, regardless of the general or the prior art mentioned above, the plating layer must be attached by another label or printing. However, the label or printing is basically not "invasive", that is, the indicator sticker. Or printed on the surface of plastic materials, so it is easy to wear out when consumers often touch and use. 200806821 [Invention content] • - The main purpose of this book is to design a three-dimensional visual effect of plastic plating.

Please refer to the first figure, the surface plating process of the plastic material of the present invention comprises at least the following steps: (a) coating an interface activator on the surface of the plastic material as a DISFERSING Surfactant, due to The surfactant has the characteristics of uniform dispersion, so that the quality of the color and the stability of the product are controlled. At the same time, the surface of the electroplated plastic material and the metal and electrolyte body can be fully utilized. (b) a technique of performing chemical reduction deposition on the level of the surfactant to deposit a conductive film by chemical reduction, and the metal of the conductive layer may utilize nickel, copper, silver, cobalt, gold or chromium. Any one. Since the plastic is not easily conductive, the surface of the plastic is first electrically conductive, so that the internal locking surface (interl〇cking Φ surface) ° (c) is mechanically or chemically roughened to the surface of the conductive layer. Forming a layer of electric money; the genus of the plating layer can utilize any one of nickel, copper, silver, diamond, gold or chromium. (d) A two-dimensional or multiple surface "invasive" processing method that allows the plated metal layer to form a "stereoscopic" visual effect on the surface of the plastic material component.
