If the internal spray painting and laser etching are adopted, due to the wall thickness factor of the ornament, light emitted by a light source inside the ornament is refracted when passing through the ornament, and the image of the pattern is also refracted together, so that the pattern boundary seen by human eyes is fuzzy and unclear;
if the outer surface is painted and the laser etching is adopted, a boundary line can be formed on the outer surface after the laser etching, although the boundary of the luminous pattern can be clear when the luminous pattern is lightened, the boundary line trace of the very obvious pattern can be seen by naked eyes when the luminous pattern is not lightened, and the attractiveness of the ornament is seriously affected.

FIG. 2 is a schematic sectional view of the garnish of embodiment 2.
Detailed Description
The invention is further described below with reference to the accompanying drawings and specific examples.
Example 1, referring to fig. 1, a surface treatment method of a decorative member includes:
s101, providing a transparent or semitransparent plastic base material;
s102, forming a shading priming paint layer on the outer surface of the base material; in the step, the shading primer layer has the functions of covering the flaws of the plastic base material, shading the light rays emitted from the inner surface direction of the plastic base body and enhancing the adhesion;
s103, removing the shading primer layer in a preset area on the outer surface of the shading primer layer through laser etching to form a light-transmitting pattern area, wherein the thickness removed through laser etching is larger than or equal to that of the shading primer layer; in the step, the purpose of removing the shading primer layer by laser radium carving is to enable light rays emitted by a light source in the plastic substrate to form a preset luminous pattern according to the shape of the transparent pattern area;
s104, forming a PVD vacuum coating layer on the outer surfaces of the shading primer layer and the light-transmitting pattern region, wherein the PVD vacuum coating layer is a light-transmitting or semi-light-transmitting PVD vacuum coating layer; in the step, the PVD vacuum coating layer is a material appearance with metal texture finally embodied by the decoration, and meanwhile, due to the special process of PVD, the thickness of the vacuum coating layer is much thinner than that of a coating layer or a paint layer of the traditional process, so that the vacuum coating layer cannot completely absorb shielding light, and the decoration has certain light transmission capacity; the thickness of the vacuum coating layer in this embodiment is less than 0.2 μm, and the material is indium, but the thickness and the material are not limited to those provided in this embodiment as long as the finally formed vacuum coating layer has a light transmission effect;
s105, forming a protective finish paint layer on the outer surface of the PVD vacuum coating layer, wherein the protective finish paint layer is transparent; in the step, the protective finish paint layer has the functions of protecting the vacuum coating layer and transmitting light.
When the decoration piece after the surface treatment method is installed on a product for actual use, when a light source in the decoration piece is not lightened, a user can only see a vacuum coating layer on the surface of the decoration piece, namely the decoration piece with metal texture, and cannot see a light-transmitting pattern area below the vacuum coating layer and a pattern boundary generated by the color difference of the shading primer layer and the material color of the decoration piece or influence elements on the attractive surface of the decoration strip; when the light source in the decoration is lightened, the user can see the luminous pattern with clear pattern boundary on the decoration, thus the aesthetic property of the decoration and the definition of the luminous pattern are considered integrally.
The principle that a user cannot see a light-transmitting pattern area and a pattern boundary when a light source is not lighted is as follows:
the appearance of the surface of an object which can be seen by human eyes is actually the result of the integration of all reflected light rays which enter the eyes after external light rays irradiate the object. Theoretically, the human eye should be able to externally view the see-through pattern area and the pattern boundaries, but in practice it is substantially impossible. The external light irradiating the surface of the decoration part occurs in three conditions, firstly, the external light enters eyes after being reflected by the vacuum coating layer, and the part of reflected light actually forms the appearance of the decoration part seen by a user; secondly, the light absorbed by the vacuum coating layer is not considered; the light rays penetrating through the vacuum coating layer, the lower layer of the vacuum coating layer comprises a shading primer layer and a light-transmitting pattern area, and the shading primer layer directly absorbs the light rays and does not reflect the light rays, so that the appearance of the decorating part is not influenced; although the light-transmitting pattern region can transmit light, the light rays pass through the light-transmitting pattern region and then enter the interior of the decoration, the light rays which can be reflected by the surface of an object in the interior of the decoration and then enter the light-transmitting pattern region are few in proportion, and in addition, the part of the light rays can enter eyes after continuously passing through the vacuum coating layer and being absorbed by the part of the light rays; that is, in fact, in the case of only external light, the light reflected back from the transparent pattern area is weak even if there is any light, and the weak light is directly negligible compared with the light reflected from the vacuum coating layer, and human eyes cannot recognize the difference, so that the human eyes cannot actually observe the transparent pattern area and the pattern boundary in the case of only external light.
Because the shading priming paint layer also has certain thickness, after the shading priming paint layer in the light-transmitting pattern area is removed by laser radium carving, the light-transmitting pattern area has certain depth difference with other areas, and finally the edge of the light-transmitting pattern area can be seen to have a sense of point depression although the light-transmitting pattern area and the pattern boundary cannot be seen in the decoration. To solve this problem, in this embodiment, the step of forming a PVD vacuum coating layer on the outer surfaces of the opaque primer layer and the transparent pattern region includes: forming a transparent intermediate paint layer on the outer surfaces of the shading primer layer and the light-transmitting pattern region, and forming a PVD vacuum coating layer on the outer surface of the transparent intermediate paint layer; transparent medium coat layer can fill printing opacity pattern area because the laser radium carving removes the vacancy that produces behind the shading priming paint layer, avoids the printing opacity pattern area of decoration to have sunken flaw.
Example 2 referring to fig. 2, a decorative part, which can be obtained by the surface treatment method of example 1, comprises a transparent or semitransparent plastic substrate 1, wherein the outer surface of the plastic substrate 1 is coated with a shading primer layer 2, a PVD vacuum coating layer 3 and a protective finish layer 4 in sequence from inside to outside; the preset area of the shading primer layer 2 is provided with a light-transmitting pattern area, the light-transmitting pattern area is formed by removing the shading primer layer in the area through laser etching, and the PVD vacuum coating layer 3 covers the light-transmitting pattern area; the PVD vacuum coating layer 3 is a transparent or semi-transparent coating layer; the protective finish paint layer is a transparent paint layer.
In the embodiment, the shading primer layer on the surface of the decoration part is used for covering flaws of the plastic base material, shading light rays emitted from the inner surface direction of the plastic base body and enhancing adhesive force; the purpose of removing the shading primer layer by laser radium carving is to enable light rays emitted by a light source in the plastic substrate to form a preset light-emitting pattern according to the shape of the light-transmitting pattern area; the PVD vacuum coating layer has the function of finally embodying the appearance of a material with metal texture for the decoration and has a certain light transmission function; the protective surface paint layer is used for protecting the vacuum coating layer and transmitting light.
On the basis of the scheme, in order to avoid the defect that the light-transmitting pattern area of the decoration piece is sunken, a transparent middle paint layer is further covered between the shading primer layer and the PVD vacuum coating layer of the decoration piece.
The thickness of the coating of the PVD vacuum coating layer is less than 0.2 μm; the PVD vacuum coating layer is made of indium.
Although the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and various changes in form and details may be made within the scope of the appended claims.
