The substrate layer 5 is co-extruded with the adhesive layer 4 to ensure the connection strength of the two.

[0026] The composite decorative surface for the automobile of the embodiment mainly adopts the structure of the above five layers. The protective layer 1, i.e. the acrylic layer, mainly uses PMMA or organic glass as the raw material, has the characteristics of high transparency, good processing performance and strong weather resistance, can provide the overall automobile decorative film with basic transparency, helps to realize the visual effect of bright and elegant combination, and provides an attachment basis for the subsequent layers. As the outermost layer of the decorative film, the acrylic layer needs to ensure a certain degree of transparency while taking into account the production cost and production efficiency. The thickness of the acrylic layer of the embodiment is preferably within 50-200 um.

[0027] The pattern layer 2 is an ink layer, which is used to provide color and patterns for the automobile decorative film. Through careful design and printing, the ink layer can realize a variety of visual effects, including bright colors, matte colors and patterns, etc., thereby meeting the personalized needs of the car owner. The thicker the ink layer, the more vivid and full the color it can provide. However, the cost and processing difficulty will also increase accordingly. Therefore, considering the above factors, the thickness of the ink layer in the embodiment is preferably 10-50 um.

[0028] Compared with the automobile decorative film in the prior art, the metal plating layer 3 and the adhesive layer 4 are arranged between the ink layer and the substrate layer 5 in the embodiment. The metal plating layer 3 can form a nanoscale metal layer on the film by vacuum evaporation or vacuum magnetron sputtering technology. The metal material includes but is not limited to aluminum, silver, nickel, etc. These metals have high reflectivity to light and help to improve the heat insulation effect. At the same time, the metal plating layer 3 can also increase the hardness and wear resistance of the overall decorative film, thereby improving the overall structural performance. Due to the reflection effect of the metal plating layer 3 on light, the automobile decorative film can add bright metallic color and visual effect.

[0029] The adhesive layer 4 is preferably a polyurethane layer, which can tightly combine the metal plating layer 3 and the substrate layer 5 together. As a material with good wear resistance and weather resistance, the polyurethane layer can ensure the stability and durability of the overall structure of the decorative film. In addition, the polyurethane layer also has a certain elasticity, which helps to resist external impact and reduce scratches, further enhancing the structural performance.

[0030] The substrate layer 5 as the innermost layer of the decorative film is preferably an ABS layer, ABS is a thermoplastic plastic with high strength, impact resistance and processed characteristics, which provides additional protection and support for the overall automobile decorative film, enhances the overall strength and durability of the decorative film, in order to ensure good support effect and control the production cost, the thickness of the ABS layer is preferably within 0.5-2mm.

[0031] In summary, the automobile decorative film of the embodiment can give the automobile decorative film a combination of bright and elegant appearance display effect and enhance the structural performance through the synergistic effect of the acrylic layer, the ink layer, the metal plating layer 3, the polyurethane layer and the ABS layer, which is reflected in: first, the ink layer can provide rich pattern and color selection, the metal plating layer 3 increases the metal luster effect, the acrylic layer ensures high transparency, and the combination of bright and elegant visual effect is realized; second, the polyurethane layer ensures the close combination of the metal plating layer 3 and the ABS layer, improves the stability of the decorative film, the metal plating layer 3 and the ABS layer increase the hardness and wear resistance of the film, and the polyurethane layer and the ABS layer also have certain elasticity, which helps to resist external impact and reduce scratches.

Figure 2 Specifically, the embossed pattern 11 can be formed on the acrylic layer opposite to the pattern layer 2, so that the embossed pattern 11 is integrally formed on the acrylic layer. After the above-mentioned mode is adopted, the texture or pattern can be generated on the surface of the acrylic layer, compared with the smooth surface of the acrylic layer in the first embodiment, the visual effect of the automobile decorative film product can be significantly improved, the touch feeling is enhanced, and the market competitiveness of the product is improved.

[0034] Third embodiment

[0035] As shown in the first embodiment, the automobile decorative film with a combination of bright and elegant of the utility model, based on the first embodiment, the difference lies in, the one side of the protection layer 1 opposite to the pattern layer 2 is provided with the embossed pattern 11.

[0036] Figure 3 Compared with the second embodiment, the ink layer of the embodiment mainly includes the ink printing area and the digital jet printing area, the ink coating 21 and the digital jet printing layer 22 are respectively filled and arranged, the digital jet printing layer 22 and the ink coating 21 are sealingly connected and combined to form the pattern layer 2.

[0037] Compared with the second embodiment, the ink layer of the embodiment mainly includes the ink printing area and the digital jet printing area, the ink coating 21 and the digital jet printing layer 22 are respectively filled and arranged, the digital jet printing layer 22 and the ink coating 21 are sealingly connected and combined to form the pattern layer 2.

[0038] ​The ink coating 21 can be applied on the specific area of the metal plating layer 3, that is, the area corresponding to the ink printing area, and the metal luster particles are doped in the ink coating 21, so that the main raw material of the ink coating 21 is a metal luster ink made of fine metal flakes, usually aluminum flakes for silver ink and copper flakes for gold ink, and when the ink is dried, the flakes can form a layer of embossed metal foil, showing bright metal luster and adding color to the decorative film.

[0039] On the remaining area of the metal plating layer 3, a digital inkjet layer 22 is formed by using a digital inkjet technology, which can form different patterns or characters through high-precision printing according to the needs of users, and the digital inkjet technology has high resolution and flexibility, so the digital inkjet layer 22 can form various complex patterns and colors, thereby realizing contrast and complementary effect with the ink coating 21. By using the combination of the above two technologies, two or more different ink display patterns can be formed on the metal plating layer 3, which can be simple lines, geometric shapes, or complex image and pattern combinations. Due to the characteristics of the metal luster ink and the digital inkjet technology, the patterns will show unique visual effects and tactile experiences, and the combination of these technologies provides more possibilities for the decorative effect and personalized customization of the decorative film.
