Abstract
Description
Technical Field
[0001] This utility model belongs to the field of in-mold injection molding technology, specifically relating to a three-dimensional effect film with a two-color center and a colored electroplated surface. Background Technology
[0002] Automotive interior trim pieces are accessories installed inside vehicles primarily for aesthetic purposes. With the continuous development and rise of automotive culture, many car manufacturers are constantly evolving and updating their interiors to reflect the meaning and symbolism of different car brands. In recent years, the styles and functions of automotive interiors have proliferated. For example, some interior trims with lighting effects rely on internal light-emitting elements to enhance their decorative effect and display vibrant colors, satisfying both the quality and practicality needs of ordinary consumers and the aesthetic demands of younger consumers. However, the current three-dimensional effect relies entirely on the internal lighting of the trim pieces. If the internal light-emitting elements are damaged, they need to be removed for repair, and the need for electricity to power the lighting does not comply with current environmental protection, energy conservation, and emission reduction requirements.

[0010] 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.
[0011] 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.
[0012] 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.
[0013] Please see Figure 1 This utility model provides a technical solution: a three-dimensional effect film with a two-color center and a colored electroplated surface. The three-dimensional effect film includes a PC layer 1 at the bottom; an adhesive layer 2 on top of the PC layer 1; a varnish layer 3 on top of the adhesive layer 2; a printing layer 4 on top of the varnish layer 3; an electroplating protective layer 5 on top of the printing layer 4; a bright silver PVD electroplating layer 6 on top of the electroplating protective layer 5; a gradient NCVM electroplating layer 7 on top of the bright silver PVD electroplating layer 6; a UV transfer layer 8 on top of the gradient NCVM electroplating layer 7; a high-precision etched texture layer 9 on top of the UV transfer layer 8; a PMMA layer 10 on top of the high-precision etched texture layer 9; a UV paint layer 11 on top of the PMMA layer 10; a PET film layer 12 on top of the UV paint layer 11; and a PE film layer 13 at the bottom of the PC layer 1.
[0014] The bottom layer of the film is PC layer 1, a thin film layer made of PC material. An adhesive layer 2 is placed on top of PC layer 1 for bonding. Above the adhesive layer 2 is a varnish layer 3, a synthetic resin layer formed from varnish, a type of coating that does not contain coloring substances; its main components are resin and solvent, or resin, oil, and solvent. Above the varnish layer 3 is a printing layer 4, and after the pattern is printed on the printing layer 4, an electroplating protective layer 5 is applied. The electroplating protective layer 5 provides protection for subsequent electroplating operations, mainly using electroplated silicon dioxide for protection. Above the electroplating protective layer 5, a bright silver PVD electroplating layer 6 and a gradient NCVM electroplating layer are sequentially electroplated. The bright silver PVD electroplating layer 6 is made of bright silver material using PVD electroplating, which is a vacuum electroplating process, including vacuum evaporation, sputtering, and ion plating. After electroplating a bright silver PVD layer, a gradient NCVM electroplating layer is then electroplated 7. NCVM electroplating is a discontinuous coating technology or non-conductive electroplating technology, which is a technique derived from ordinary vacuum electroplating. Vacuum electroplating, abbreviated as VM, refers to the organic transformation of metal materials under vacuum conditions using specific chemical and physical methods, causing the metal to be converted into particles and deposited or adsorbed on the surface of plastic materials to form a film, also known as a coating. Vacuum non-conductive electroplating is also called NCVM electroplating. UV transfer is then performed on top of the gradient NCVM electroplating layer to obtain a UV transfer layer 8. UV transfer utilizes the non-adhesive properties of UV transfer adhesive to transfer various ultra-thin effects onto special sheets through the UV transfer process. High-precision etching is then performed on top of the UV transfer layer to obtain a high-precision etched texture layer 9. Etching is also commonly known as photochemical etching, which refers to removing the protective film of the area to be etched after exposure and development, and then contacting the chemical solution during etching to achieve a dissolving and corroding effect, forming concave or convex shapes. A PMMA layer 10 is then placed on top of the high-precision etched texture layer 9. PMMA, or polymethyl methacrylate, is a thin film layer that achieves high transparency, low cost, ease of processing, and good toughness. A UV coating layer 11 is then placed on top of the PMMA layer 10. This UV coating layer 11 provides a hard and wear-resistant protective layer for the product through specific coatings and UV curing technology. The coating can be polyurethane coating, inorganic nano-ceramic coating, or radiation-cured coating, etc. These coatings are applied to the product surface through spraying, dipping, or other methods, and then cured by UV light to form a hard protective layer. A PET film layer 12 is placed on top of the film, and a PE film layer 13 is placed on the bottom, both serving to protect the film.
[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
