As a supplement to the technical scheme, the back of the exterior trim needs to be close to the light-emitting source, and in order to avoid damaging the second PVD metal plating, a second protective layer is arranged on the back of the second PVD metal plating.
When transparent material itself material is softer, when the adhesive force is relatively poor, transparent priming coat need have been arranged between transparent material and first PVD metallic coating, and transparent priming coat can make things convenient for the shaping of first PVD metallic coating.
Whether a front protection layer needs to be arranged on the front surface of the transparent material is selected according to the material of the transparent material, and when the material of the transparent material is acrylic, the front protection layer does not need to be added.
The transparent priming coat is formed by improving the back adhesive force of the transparent material, so the transparent priming coat can be made of transparent paint or printing ink materials and a transparent dielectric film, and the transparent dielectric film is arranged in a PVD mode by selecting silicone oil, silicon dioxide and the like.
In order to form the appearance effect of the back electroplating silver of the decorative piece, the first PVD metal coating and the second PVD metal coating are generally selected from aluminum or chromium or indium or tin as metal coating materials.
The first PVD metal coating and the second PVD metal coating are selectively used for evaporation coating, sputtering coating or ion coating as coating modes.
Has the advantages that: the invention relates to a light-tight and light-tight automobile luminous exterior trim part, which is characterized in that a first PVD metal coating, a first transparent protective layer and a second PVD metal coating are arranged, so that the shading effect of the inner side of the exterior trim part is improved, the defects of light transmission and light leakage are avoided, the first transparent protective layer is arranged, the first PVD metal coating and the second PVD metal coating are isolated, and the first PVD metal coating is protected from being damaged. The invention has the advantages of enlarging the selection range of the coating material, realizing the purpose of lighttightness, eliminating light leakage, reducing the process difficulty, reducing the coating thickness, reducing the cost and the like.

Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
Originally, when the luminous exterior trimming part of an automobile is produced, a thick metal coating needs to be arranged on the back of the exterior trimming part to solve the technical problems of light transmission and light leakage.
As shown in fig. 1, in the present technical solution, by providing the first PVD metal plating layer 4 and the second PVD metal plating layer 6, since pinholes existing in the first PVD metal plating layer 4 itself can generate light leakage and light transmission, by adding the second PVD metal plating layer 6 at the rear end of the first PVD metal plating layer 4, the pinholes of the first PVD metal plating layer 4 can be covered by the second PVD metal plating layer 6, and the pinholes of the two are not overlapped, thereby effectively avoiding the light leakage and light transmission, and by providing the first transparent protection layer 5 between the two, the purpose of solving the technical problems of light transmission and light transmission can be achieved, on the other hand, by using the first transparent protection layer 5, the adhesion of the second PVD metal plating layer 6 can be significantly enhanced, and the first PVD metal plating layer 4 can be prevented from being damaged by the second PVD metal plating layer 6, and the overall thickness of the plating layer can be reduced, greatly reduces the production cost and the process difficulty.
The back of the decorative piece is close to the strong light source, and in order to ensure that the second PVD metal coating 6 cannot be damaged, a second transparent protective layer 7 is arranged on the back of the second PVD metal coating 6.
When the decoration is coated, the first PVD metal coating 4, the first transparent protective layer 5, the second PVD metal coating and the second transparent protective layer 7 are completed, then a removing process is carried out, a hollowing operation is carried out according to pre-designed pictures and texts, the picture and text parts are exposed, and a light transmission area 8 is formed.
When the transparent material 2 is selected to be soft in texture and poor in coating adhesive force, the transparent priming coat 3 needs to be arranged on the back surface of the transparent material 2, and the coating adhesive force can be increased by the transparent priming coat 3, so that the coating operation is facilitated.
In order to protect the transparent material 2 and improve the aesthetic appearance of the garnish, a front surface protection layer 1 is provided on the front end surface of the transparent material 2.
The following are specific embodiments of the technical scheme:
the front protection layer 1 can be selected according to the material of the transparent material 2 to determine whether the front protection layer 1 is needed, for example, when the transparent material 2 is PMMA, the front protection layer 1 is not needed, the first PVD metal plating layer 4 is a metal with an electroplated silver appearance, such as aluminum, chromium, indium, tin, and the like, and the PVD mode can be any plating mode, such as evaporation plating, sputtering plating, ion plating, and the like; the first transparent protective layer 5 may be a transparent dielectric film realized in a light-transmitting PVD manner, such as silicone oil, silicon dioxide, or the like, or may be a transparent paint realized in a light-transmitting spray manner, or may be a transparent ink realized in a printing manner; the second PVD metal plating layer 6 is a metal having an appearance of electro-silvering, such as aluminum, chromium, indium, tin, and the like, and may be the same as or different from the metal of the first PVD metal plating layer 4, and the PVD method may be any plating method, such as evaporation plating, sputtering plating, or ion plating; the second transparent protective layer 7 may be a transparent dielectric film implemented by a light-transmitting PVD method, such as silicone oil, silicon dioxide, or a transparent paint implemented by a light-transmitting spray coating method, or a transparent ink implemented by a printing method, and may also be omitted under the condition of non-harsh use conditions.
