Technical Field
The invention relates to a sticker, in particular to a three-dimensional embossed crystal sticker and a method thereof, wherein the three-dimensional embossed crystal sticker is formed by laminating and overlapping multiple material layers to generate multilayer reflection and refraction to simulate the luster of a crystal.
Background
In daily life, ornaments capable of producing gloss are often needed, and the ornaments can achieve an aesthetic effect. The decoration usually can reach the effect that produces the gloss through two kinds of ways, one of them is that the decoration contains the light source among them, directly plays the luminous effect through the light source in the decoration, for example uses LED etc. uses the light source and need use external power supply or battery energy supply, and is comparatively suitable for the article that needs very strong illumination effect of decoration.
The other approach is to use the principle of light reflection and refraction to achieve the effect of generating gloss, and a built-in light source is not needed by using the approach. The decorative materials capable of achieving the reflection and refraction effects can be roughly classified into a cut type and an embossed type.
Cutting type ornamental material includes diamond, quartzy and glass etc. in order to reach the effect that produces bright gloss, needs earlier to cut above-mentioned material, makes its formation have the structure of a plurality of tangent planes, later need right the tangent plane is polished, uses the processing machine of cutting type ornamental material needs higher precision, has higher requirement to operator's operating skill, and the course of working is comparatively loaded down with trivial details, therefore the cost of manufacture is higher. Because the cutting type decorative material has a multi-section structure, when the cutting type decorative material is required to be adhered to the surface of an ornament, the contact area is small, and the adhesion is not very firm; the cutting type ornament is usually used for inlaying, and the inlaying mode comprises the steps of directly inlaying the cutting type ornament on the surface of an ornament to be decorated and inlaying the cutting type ornament on a specific object and then fixing the specific object on the surface of the ornament to be decorated; either way requires the use of an inlay, thus limiting the design of the decorative pattern.
The embossed decorative material is manufactured by electroplating a single material layer and then bending, a reflection plane is formed by utilizing an electroplating surface, a plurality of reflection planes are formed by bending the single material layer, and light is emitted by the plurality of reflection planes to achieve the effect of generating gloss. Compared with a cutting type decorative material, the press convex type decorative material has less reflecting surface and does not have a refraction structure in structure, so the light splitting effect of the cutting type material cannot be achieved, and the luster is not as good as that of the cutting type material. Only through single face electroplating as the plane of reflection, the electroplating face easily produces wearing and tearing, and the electroplating face reflection effect after wearing and tearing descends seriously, not only influences the bright degree of gloss, and aesthetic measure also can receive the influence. For cutting type material, use and press protruding type ornamental material comparatively to conveniently paste on by embellishment surface, single-layer embossing type ornamental material adopts the sticker mode to paste on by embellishment surface, can the person of facilitating the use decorate according to own hobby very conveniently.

Detailed Description
Referring to fig. 1 to 3, which are schematic views illustrating a preferred embodiment of the present invention, the embossed crystal sticker 1 of the embodiment includes a first material layer 10, a second material layer 20, and a third material layer 30.
As shown in fig. 1, the embossed crystal sticker 1 may take a wide variety of designs, for example, in the embodiment of fig. 1, the embossed crystal sticker may be implemented in, but not limited to, a butterfly shape. The first material layer 10 and a solid border area 101 printed on the lower surface of the first material layer 10 can be seen. The three-dimensional border area 101 serves as a boundary between the embossed area and the flat area of the first material layer 10, and is printed on the inner surface of the first material layer 10 before the first material layer is pressed. The first material layer 10 is made of transparent hard PVC materials, so that the transmittance of the first material layer 10 can be ensured, the material strength can be ensured by adopting PVC plastic materials, and the service life is prolonged.
As shown in fig. 2, the first material layer 10 is sharply pressed along the solid border area 101 with the solid border area 101 as a boundary during pressing, so that the first material layer 10 forms a sharp protrusion at the position of the solid border area 101. The convex area of the solid border area 101 has no light refraction. The closed inner area of the three-dimensional border area 101 is pressed according to the crystal structure to be achieved, and the simulated crystal structure has a parallel surface parallel to the plane of the first material layer 10 and a plurality of transmission surfaces surrounding the parallel surface, so that the structure shown in fig. 1 is formed. Since the first material layer 10 is made of a transparent material, the light reflection capability is weak, the main function of the first material layer 10 is to make light pass through to the reflection surface of the second material layer 20, make reflected light from the reflection surface of the second material layer 20 pass through, and have a refraction effect on the passed light, and the first material layer 10 and the second material layer 20 together form a crystal structure.
As shown in fig. 2, the second material layer 20 is made of the same PVC material as the first material layer 10. Before the second material layer 20 is pressed, an aluminum plating film operation is firstly performed on the upper surface of the second material layer 20, and after the operation is completed, an aluminum plating film 201 is formed in a specific area of the upper surface of the second material layer, wherein the area covered by the aluminum plating film 201 corresponds to the area printed by the three-dimensional binding area 101 on the first material layer 10 and does not include the area covered by the three-dimensional binding area 101. After the coating operation is completed, the second material layer 20 needs to be pressed in the same manner as the first material layer 10 but in the opposite direction, so that the embossed regions of the first material layer 10 are symmetrical to the embossed regions of the second material layer. The aluminum film 201 of the second material layer 20 reflects light, and the light transmitted from the first material layer 10 is reflected by the plurality of reflection surfaces formed by pressing. The embossed regions of the first material layer 10 and the embossed regions of the second material layer combine to form a three-dimensional embossed crystal structure 102. The light rays in the three-dimensional crystal structure 102 are reflected by the first material layer 10 and the second material layer 20, and then are emitted through each surface of the first material layer 10, so that the viewer can see luster. As shown in fig. 2, the third material layer 30 does not need to be pressed, but only needs to be fixed together with the upper surface thereof and the lower surface thereof, and the lower surface thereof is subjected to a glue coating process.
