[0026] The present application provides a three-dimensional pattern plate, comprising a base layer 10, a base layer 11, a first color layer 12, a first rubbing layer 14, a first ink layer 15, a second rubbing layer 17, and a protective layer 18 arranged in sequence; the first rubbing layer 14 and the second rubbing layer 17 have textures; the first ink layer 15 can be magnetized. The base layer 10 has a certain thickness and elasticity, and can restore its shape after bending. The base layer 11 is arranged on the base layer 10, and can be used to enhance the connection firmness between the first color layer 12 and the base layer 10. The base layer 11 can be colored or colorless. When the base layer 11 is colored, the plate has a composite color and richer colors. The first color layer 12 can be set with any color as needed. The first color layer 12 can be used to set off the first rubbing layer 14, the first ink layer 15, and the second rubbing layer 17, so that the first rubbing layer 14, the first ink layer 15, and the second rubbing layer 17 have better display effects, more colorful colors, and more vivid textures. The first rubbing layer 14 and the second rubbing layer 17 can be used to print various textures (for example: 3D and / or 2D), so that the plate has a good 3D effect. A first ink layer 15 that can be magnetized is arranged between the first rubbing layer 14 and the second rubbing layer 17. The first ink layer 15 can produce a three-dimensional 3D pattern under the effect of magnetic attraction. Therefore, the first ink layer 15 can give the first rubbing layer 14 and the second rubbing layer 17 a very good 3D pattern transition feeling, and the 3D effect is better. During production, the magnet with a shape attracts the first ink layer 15, and a pattern similar to the magnet is produced on the first ink layer 15. In this way, the first ink layer 15 can provide a transition effect for the first rubbing layer 14 and the second rubbing layer 17, and the 3D effect is better. The protective layer 18 has a very high hardness, and the protective layer 18 can provide protection for the plate, making it more scratch-resistant. Furthermore, a three-dimensional pattern plate includes a base layer 10, a base layer 11, a first color layer 12, a first sealing layer 13, a first rubbing layer 14, a first ink layer 15, a second sealing layer 16, a second rubbing layer 17, and a protective layer 18. Preferably, the base layer 10 is provided with a rough surface to increase the bonding strength between the base layer 10 and the base layer 11.

[0027] Preferably, the base layer 10 is a plate made of polypropylene or polyethylene terephthalate. The base layer 10 has a certain thickness, for example, any value of 0.05mm-1mm, such as 0.02mm, 0.04mm, 0.06mm, 0.08mm. The base layer 10 in this embodiment is polypropylene. Polypropylene, referred to as PP, is a polymer formed by polyaddition reaction of propylene. It is a white waxy material with a transparent and light appearance, and is very suitable for making the back cover of electronic products. Of course, the base layer 10 in this embodiment can also be added with color powder to make the base layer 10 with color.

[0028] Preferably, the base layer 11 is an acrylic resin layer; the first color layer 12 is an acrylic resin layer with color. The acrylic resin layer can be quickly cured by ultraviolet light (UV), which is conducive to rapid prototyping of the product. The first color layer 12 is an acrylic resin mixed with color powder, so it has color. The thickness of the base layer 11 and the first color layer 12 is very thin, so the base layer 11 and the first color layer 12 can be quickly formed under the action of ultraviolet light. The thickness of the base layer 11 and the first color layer 12 in this embodiment is between 1-20µm, and of course it can also be other numerical ranges, without specific limitation.

[0029] Preferably, a first sealing layer 13 is provided between the first color layer 12 and the first rubbing layer 14; and a second sealing layer 16 is provided between the first ink layer 15 and the second rubbing layer 17. The first sealing layer 13 and the second sealing layer 16 are preferably transparent. The first sealing layer 13 and the second sealing layer 16 can play a role of separation. After the first color layer 12 is cured, the first sealing layer 13 encapsulates the first color layer 12 to avoid interference from subsequent layers, thereby ensuring the purity of the color of the first rubbing layer 14. After the first ink layer 15 is cured, the second sealing layer 16 separates the first ink layer 15 and the second rubbing layer 17 to avoid interference between the first ink layer 15 and the second rubbing layer 17, thereby ensuring the purity of the color and pattern of the second rubbing layer 17.

[0030] Preferably, the first sealing layer 13 and the second sealing layer 16 are transparent or colored acrylic resin layers. The thickness of the first sealing layer 13 and the second sealing layer 16 in this embodiment is between 1-20 μm, and ultraviolet (UV) is used for rapid curing. The first sealing layer 13 and the second sealing layer 16 in this embodiment are transparent, which can achieve a good light transmission effect and make the color more vivid.

[0031] Preferably, the first rubbing layer 14 and the second rubbing layer 17 are acrylic resin layers; wherein the texture of the first rubbing layer 14 is a 2D or 3D texture; the texture of the second rubbing layer 17 is a 2D or 3D texture. In this embodiment, the texture of the first rubbing layer 14 is a 2D texture, and the texture of the second rubbing layer 17 is a 3D texture, and this combination can better highlight the 3D effect. Of course, the texture patterns of the first rubbing layer 14 and the second rubbing layer 17 can be arbitrarily set as needed, and the above combination is just one of the combinations.

[0032] Preferably, the first ink layer 15 is a magnetizable acrylic resin layer. The first ink layer 15 is an acrylic resin mixed with pigments, additives, butyl acetate, propylene glycol methyl ether acetate, and magnetic materials (such as magnetic powder, magnetizable metal powder, magnetizable metal oxide, etc.). Of course, the first ink layer 15 can also be a magnetizable pigment, such as black iron oxide (Fe3O4) and brown iron oxide (Fe2O3), most of which are needle-shaped crystals less than 1μm. It is very easy to achieve magnetic arrangement after magnetic field treatment and obtain high residual magnetism. The ink prepared after adding it to the ink shows magnetism and becomes magnetic ink. It is widely used in the classification, retrieval, and identification of bank tickets and postal services. It can be made into varieties such as magnetic lead printing ink and magnetic offset printing ink.

[0033] Preferably, the protective layer 18 is one of an acrylic resin layer and a polyurethane layer. Both the acrylic resin layer and the polyurethane layer can be quickly cured by ultraviolet light (UV), which is conducive to rapid product molding. The thickness of the protective layer 18 is relatively thin and is between 1-20 μm.

[0034] Preferably, a metal wire is embedded in the base layer 10. This design is conducive to enhancing the thermal conductivity of the base layer 10 and is more conducive to the heat dissipation of the mobile phone. The metal wire in this embodiment is preferably copper wire or aluminum wire.
