Description

The coating structure that 3C Product is used

Technical field

The utility model relates to a kind of about the technology to surperficial coating liquid or other fluid, is meant a kind of 3C Product metallic luster coating structure that nonmetal characteristic as the metalloid gloss is provided especially.

Background technology

3C Product is meant three classes in conjunction with computer (Computer), communication (Communication) and consumer electronics (Consumer electronics).

Along with money communication industry technology progresses greatly year by year, the development of 3C Product built-in function is also day by day attained ripe, present outward appearance also becomes the user gradually and buys one of necessary consideration, in view of this, manufacturer is devoted to create the sight of product fashion invariably and leads the product popularity to attract the consumer to buy, it is flourish day by day to bring up the 3C Product sufacing, at present the two non-engineering plastics of big class material and the light metal of extensive utilization do not belong to 3C Product, both all provide the 3C Product interior structural support, also be devoted to show the design aesthetic feeling of product, be to have good mouldability with the engineering plastics advantage, and low price, and the light metal advantage is to have superior stiffness and intensity, and anti-electromagnetic wave and thermal diffusivity are good, and it is main flow that present 3C Product still adopts engineering plastics.

In order to give the 3C Product metallic luster that engineering plastics are made, be provided with metal coating structure 90 at 3C Product now, as shown in Figure 1, it is made up of a basic unit 91 and a chromium atom layer 92 that is incorporated in this basic unit 91, perhaps form by a basic unit 92 with al atomic layer or tin atom layer or indium stannum alloy layer or silico-aluminum layer, aforementioned existing 3C Product is further analyzed with the metal coating structure, is still had following problem:

1. this 3C Product, will influence the 3C Product wireless transmission and hinder signal receiving/transmission because have decay of RF RF-reflective and the characteristic that absorbs with metal coating structure 92, and in a single day the user finds that the easy signal of 3C Product is bad, and negative evaluation will spread out of thereupon.

2. this 3C Product because film thickness uniformity is difficult in first space control repeatedly, and then loses the outward appearance that attracts the consumer originally with metal alloy coating structure 92.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of 3C Product metalloid gloss coating structure, and its purpose is to provide 3C Product metallic luster outward appearance and the transmission of unimpeded signal.

For solving the problems of the technologies described above, the utility model 3C Product with the technical scheme of the coating structure of metalloid gloss and undamped RF RF energy is, comprise the increase anti-and following layer, that a basic unit, be incorporated in this basic unit and be incorporated into this and increase germanium or germanium alloy layer on anti-and the following layer, its thickness is This germanium or germanium alloy layer, color matching and a following layer and a protective layer that is incorporated on this color matching and the following layer that is incorporated on this germanium or the germanium alloy layer; Can obtain following effect by aforementioned further analysis:

1. this 3C Product avoids the 3C Product wireless transmission to be influenced with the non-conductive material of metalloid gloss coating structure employing germanium atom or germanium alloy, and the transmitting-receiving ability of unimpeded 3C Product is kept transmission quality, and the positive evaluation of lifting increases the city and accounts for rate.

2. this 3C Product adopts this protective layer opposing wearing and tearing with the metalloid coating structure, and the protection outward appearance is kept metallic luster.

3. this 3C Product sees through this with the metalloid coating structure and increases the ability of following between anti-and following layer and this color matching and following layer and then strengthening layer and the layer, and use this to increase anti-and following layer lifting reinforcement of reflex gloss, and use this color matching and following layer that the diversity of color matching is provided.

The specific embodiment

The technology that relevant the utility model adopted, means and other effect are now lifted a preferred embodiment, and cooperate diagram to be described in detail as follows.

The utility model as shown in Figure 3, comprises a basic unit 10, one and increases anti-and following layer 20, germanium (Ge) or 30, color matching of germanium alloy (Ge Alloy) layer and a following layer 40 and a protective layer 50;

This basic unit 10 is acrylonitrile-butadiene-styrene copolymer (Acrylonitrile-Butadiene-Styrene, ABS), Merlon and acrylonitrile-butadiene-styrene copolymer (PC/ABS), Merlon (Polycarbonate, PC), polymethyl methacrylate (Polymethylmethacrylate, PMMA) and Merlon and polymethyl methacrylate copolymer (PC/PMMA) to select a material one-body molded.

This increase anti-and following layer 20 then material is one-body molded for UV-cured, this increases anti-and following layer 20 is incorporated in this basic unit 10, this increases anti-and following layer 20 is used to fill up this basic unit 10 surfaces and increases light reflection.

This germanium or germanium alloy layer 30 thickness are The resistance of this germanium or germanium alloy layer 30 is more than or equal to 1000M Ω, this germanium or germanium alloy layer 30 see through physical vapour deposition (PVD) (Physical vapordeposition, PVD) vacuum plating in is incorporated into this and increases on anti-and the following layer 20, and this increases anti-and following layer 20 is used for then this germanium or germanium alloy layer 30 and this basic unit 10, this metal coating structure is to adopt this germanium or germanium alloy layer 30 nonmetal characteristic to avoid hindering 3C Product to carry out wireless transmission and keep wireless unimpededly compared to commonly using, and provides the gloss as the 3C Product metalloid to strengthen the visual perception.

This color matching and following layer 40 be polyurethane resin (Polyurethane, it is one-body molded PU) to mix colorant, this color matching and following layer 40 change and mix to such an extent that colorant carries out colour switching, this color matching and following layer 40 are incorporated on this germanium or the germanium alloy layer 30.
