[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0017] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] Please see Figure 1 This utility model provides a technical solution: a high-hardness, scratch-resistant 3D high-strength automotive door panel decorative part, comprising a 3D imitation molding layer 1 disposed at the bottom; a high-temperature resistant protective layer 2 disposed on the top of the 3D imitation molding layer 1; a printing layer 4 connected to the top of the high-temperature resistant protective layer 2 by an adhesive layer 3; a high-strength coating layer 5 disposed on the top of the printing layer 4; a PC layer 6 disposed on the top of the high-strength coating layer 5; a PMMA layer 7 disposed on the top of the PC layer 6; a high-hardness nano-coating layer 8 disposed on the top of the PMMA layer 7; a UV hardening layer 9 disposed on the top of the high-hardness nano-coating layer 8; an upper PE protective film layer 10 disposed on the top of the UV hardening layer 9; and a lower PE protective film layer 11 disposed at the bottom of the 3D imitation molding layer 1.

[0019] The 3D molding layer 1 is designed based on the shape of the car door panel, allowing the entire decorative part to better fit the car door panel. A high-temperature resistant protective layer 2 is attached to the upper surface of the 3D molding layer 1. This high-temperature resistant protective layer 2 is mainly used to protect the door panel product from damage to the printed layer due to overheating during subsequent in-mold injection molding. It is primarily protected by an electroplated silica layer. An adhesive layer 3 connects the high-temperature resistant protective layer 2 to the printed layer 4, which displays the various textures of the decorative part. To ensure good tensile strength, a high-tensile coating 5 is applied above the printed layer 4. The high-tensile coating 5 is primarily a PLA coating. PLA products will not break or deteriorate after bending. PLA, or polylactic acid, is superior to materials such as polyethylene and polypropylene in terms of strength, compressive stress, cushioning, and sealing performance. A PC layer 6, a thin film layer made of PC material, is then applied above the high-tensile coating 5. A PMMA layer 7 is placed on top of the PC layer 6, using a thin film layer of PMMA, or polymethyl methacrylate. To enhance the hardness of the door panel trim, a high-hardness nano-coating layer 8 is placed on top of the PMMA layer 7. This high-hardness nano-coating layer 8 mainly adds nanophases to the high-hardness, wear-resistant coating, further improving the coating's hardness and wear resistance while maintaining high toughness. Adding nanoparticles to the surface coating can reduce the coefficient of friction, forming a self-lubricating material, and even achieving super-lubricating properties. In some coatings, C60, buckytubes, etc., are combined to prepare new super-lubricating materials. Introducing nanomaterials into the coating can significantly improve the material's high-temperature resistance and oxidation resistance. For example, depositing a nano-Ni-La2O3 coating on the surface of Ni, due to the action of nanoparticles, prevents the short-circuit diffusion of nickel ions, improving the growth mechanism and mechanical properties of the oxide layer. A UV hardening layer 9 is formed on top of the high-hardness nano-coating layer 8. This UV hardening layer 9, through specific coatings and UV curing technology, provides a hard and wear-resistant protective layer for the product. The coating can be polyurethane coating, inorganic nano-ceramic coating, or radiation-cured coating, etc. These coatings are applied to the product surface by spraying, dipping, or other methods, and then cured by UV light irradiation to form a hard protective layer. PE protective films are formed on the top and bottom surfaces of the product, serving as the upper PE protective film layer 10 and the lower PE protective film layer 11.
