[Prior Art] Plastics are widely used in the manufacture of electronic parts due to their ease of molding and light weight. With the increasing demand for the appearance quality and aesthetics of decorative appearance parts, people are no longer satisfied with the color of the plastic itself or the single, dull color obtained by simple painting. The metallic texture is seen on the surface of the plastic case. In order to obtain the appearance of metal on the surface of the plastic casing, various plastic appearance parts are usually subjected to surface treatment such as electroplating or painting. Among them, the plating solution used in the electroplating method contains a large amount of toxic substances, which is likely to cause environmental pollution, and the sewage disposal cost after plating is high. The conventional paint treatment can produce different color products according to the needs of customers by selecting different kinds of paint colors. However, because of the unique properties of the paint, it is impossible to present a metallic texture, which makes it difficult for the user to feel the texture and added value of the metal on the plastic casing. SUMMARY OF THE INVENTION It is necessary to provide a casing having a metallic texture and a soft touch. Further, it is also necessary to provide a method of manufacturing the above casing. a casing comprising a plastic substrate, the casing further comprising a primer layer formed on the surface of the substrate, a vacuum coating layer having a metallic texture, a transparent intermediate paint layer and a transparent topcoat layer. The primer layer is directly formed on the surface of the substrate. The vacuum coating layer is formed on the primer layer. The intermediate paint layer is formed on the vacuum mineral film layer, and the middle paint layer is formed with a pattern on the surface. A lacquer layer is formed on the lacquer layer, which is formed of a rubber lacquer having a soft touch. A plastic surface treatment method comprising the steps of: providing a plastic substrate and performing surface decontamination treatment on the substrate; forming a primer layer on the surface of the decontaminated substrate; plating a surface on the surface of the primer layer a vacuum coating layer having a metallic texture; 形成 forming a transparent intermediate lacquer layer on the surface of the vacuum coating layer; printing a pattern on the surface of the lacquer layer; forming a transparent topcoat having a soft touch on the surface of the pattern and the lacquer layer Floor. The casing is formed by plating a vacuum coating layer on the surface of the plastic substrate, printing a decorative pattern on the middle lacquer layer, and finally coating an elastic rubber lacquer on the outermost layer to make the casing have a bright metallic texture. It also has a soft touch. The manufacturing method of the above casing is simple in process. [Embodiment] The housing 10 of the preferred embodiment of the present invention comprises a plastic substrate u, a primer layer 12, a vacuum coating layer 13, a transparent intermediate lacquer layer 14, and a clear topcoat layer 15. The primer layer 12 is formed directly on the surface of the substrate U, and the vacuum coating layer 13 is formed on the surface of the primer layer 12. The vacuum rhodium plating layer 13 is a coating having a metallic texture. The material A ^ material of the vacuum coating layer 13 is formed, such as tin, sulphur, titanium, indium, chromium, gold, and non-square steel, and may be a non-gold metal having a metallic appearance, such as titanium carbide. , 201016871 Any of titanium nitride, titanium oxide or oxidation 33. The intermediate lacquer layer 14 is formed on the surface of the vacuum coating layer 13, which may be colorless or colored. The surface of the lacquer layer 14 is formed with a pattern S 142'. S 142 is a color ink printed on the surface of the intermediate lacquer layer 14. The topcoat layer 15 is formed on the surface of the intermediate lacquer layer 14 and the pattern 142. The topcoat layer 15 is composed of an elastic rubber lacquer having a soft touch, which is in a matte or semi-matte state. The manufacturing method of the above casing comprises the following steps: First, a plastic substrate u is provided, and the substrate u is subjected to a surface decontamination treatment. The primer layer 12 is applied to the surface of the sweat-treated substrate u and cured. The primer layer 12 may be composed of an ultraviolet curable lacquer, which effectively adjusts the surface smoothness of the substrate, and also makes the surface gloss of the subsequent vacuum key film layer 13 higher, and the primer layer and the subsequent true line The adhesion of the film is also better. Thereafter, a vacuum bonding film layer 13 is deposited on the surface of the primer layer 12 described above. The scented film layer 13 is formed by a bond 1 having a metallic f feeling. The material of the film layer 13 may be a metal material such as tin, ming, ching, marriage, collateral, gold, hunger, steel or indium tin alloy. Any of them may also be a non-metal having a metallic appearance such as carbon carbide, titanium nitride, titanium oxide or oxide. The vacuum coating layer 13 can be formed on the primer layer 12 by a method such as vapor deposition, money plating, ion plating or electroless plating. When the outer casing of a communication product such as a mobile phone is used, the vacuum layer can be made to affect the radio frequency function of the communication product by the thickness (4) of the vacuum film. A middle lacquer layer 14 of (d) is applied to the surface of the ray film layer 13. 201016871 - The t paint layer 14 can be a helmet color, a pigment of the example. The middle lacquer layer, 4 has; and the effect of adding (d) color and ratio in the t paint layer 真空 f vacuum ruthenium layer. The pattern is printed on the lacquer layer 14 by silk screen or pad printing to the intermediate roll π section w. The pattern 142 is formed by the color ink on the surface of the enamel layer. The surface of the lacquer layer 14 is coated with a transparent topcoat layer, a surface, and the layer 15 is an elastic rubber lacquer having a soft touch, which is chewy 5, '°. & light state 'feeling, smooth, elegant appearance, solemn. The above-mentioned device is formed by plating a vacuum coating layer on the surface of the plastic substrate, printing a decorative pattern on the middle lacquer layer, and finally coating an elastic rubber lacquer on the outermost layer to make the substrate have a bright metallic appearance. It has a soft touch and looks elegant and decorative. The manufacturing method of the above casing is simple in process.
