AI Technical Summary
The color of the existing color-changing car coat protective film is relatively single, especially for dark vehicles such as black, which is easy to seep the background color and affect the final use effect.
The structure of at least two PET release protective layers is adopted, in which a self-repair coating, a TPU pearlescent layer, a TPU basic color layer and an installation glue layer are arranged in sequence between the two layers, and a TPU transparent base film layer is arranged between the TPU pearlescent layer and the TPU basic color layer. The TPU basic color layer is produced by blowing film or casting adding pigments to achieve rich pearlescent effect and improve coverage of dark car paint.
Through the superposition combination of the TPU basic color layer and the TPU pearlescent layer, a rich pearlescent effect with different dazzling colors is achieved, and the coverage of dark car paints such as black is effectively improved, reducing the problem of transparent background color.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile protective films, in particular to a color-changing car cover protective film. Background Art
[0002] Car color-changing car cover protective film is a film used to protect the car paint. It can be covered on the surface of the vehicle to provide an additional layer of protection, while also being able to change the color of the car surface. At present, the structure of the color-changing car cover protective film is usually composed of multiple layers, such as a release protective layer, a self-repairing coating, a base film layer, and an adhesive layer for installing the adhesive layer. However, the color of the current color-changing car cover protective film is relatively single, especially for dark-colored vehicles such as black, the base color is easy to show through, affecting the final use effect of the color-changing car cover protective film. Utility Model Content
[0003] The purpose of the utility model is to solve the above problems and provide a color-changing car cover protective film.
[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0005] A color-changing car cover protective film, comprising at least two layers of PET release protective layers;
[0006] A self-repairing coating, a TPU pearlescent layer, a TPU basic color layer and an installation adhesive layer are sequentially arranged between the two PET release protective layers.
[0007] As a further description of the above technical solution, a TPU transparent base film layer is also included between the PET release protection layers, and the TPU transparent base film layer is arranged between the TPU basic color layer and the installation adhesive layer.
[0008] As a further description of the above technical solution, the TPU base color layer is produced by adding pigments / masterbatch through film blowing or casting.
[0009] As a further description of the above technical solution, the self-healing coating at least includes a thermoplastic polymer and a cross-linking agent.
[0010] As a further description of the above technical solution, the thickness of the TPU pearlescent layer is 2-40 μm.
[0011] As a further description of the above technical solution, the thickness of the TPU base color layer is 20-200 μm.
[0012] As a further description of the above technical solution, the mounting adhesive layer is a pressure-sensitive adhesive.
[0013] As a further description of the above technical solution, the TPU pearlescent layer is coated on the surface of the TPU basic color layer.
[0014] The beneficial effects of the utility model are as follows:
[0015] 1. The utility model can realize a relatively rich pearlescent effect of different dazzling colors through the superposition combination of TPU basic color film and TPU pearlescent layer through the absorption, reflection and refraction of light. At the same time, due to the provision of TPU basic color layer, the coverage of dark car paint such as black can be effectively improved, and the problem of bottom color transparency can be effectively reduced.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0021] Embodiment 1
[0022] like Figure 1 As shown, in this embodiment, a color-changing car cover protective film is disclosed, which includes, from top to bottom, a PET release protective layer 1, a self-repairing layer, a TPU pearlescent layer 3, a TPU basic color layer 4, an installation glue layer 6 and a PET release protective layer 1 at the bottom.
[0023] Among them, the TPU basic color layer 4 is first produced separately by adding color or masterbatch by film blowing or casting, and then the TPU pearlescent film is produced by coating. Through the two-layer superposition combination of the TPU basic color film and the TPU pearlescent layer 3, a relatively rich pearlescent effect with different dazzling colors can be achieved through the absorption, reflection and refraction of light. At the same time, due to the setting of the TPU basic color layer 4, the coverage of dark car paint such as black can be effectively improved, and the problem of transparent base color can be effectively reduced.
[0024] For the self-repairing coating 2, it at least includes a thermoplastic polymer and a cross-linking agent, which can automatically repair tiny scratches and wear on the surface under external pressure or heat. The working principle of this coating mainly relies on the rearrangement and cross-linking of polymer chains to fill scratches and restore the original state of the film. In other preferred embodiments, ultraviolet stabilizers or antioxidants can be added internally. Ultraviolet stabilizers are usually added to the self-repairing coating 2 to protect the coating from ultraviolet damage. Antioxidants can prevent polymer degradation due to oxidation and maintain the durability and repair ability of the coating.
[0025] The mounting adhesive layer 6 is preferably a pressure-sensitive adhesive, which can quickly form a strong bond when pressure is applied and will not remain on the vehicle paint surface when removed.
[0026] Furthermore, the thickness of the TPU pearlescent layer 3 is 2-40 μm, and the thickness of the TPU base color layer 4 is 20-200 μm.
[0027] Embodiment 2
[0028] refer to Figure 2 In this embodiment, a color-changing car cover protective film is disclosed, which includes, from top to bottom, a PET release protective layer 1, a self-repairing coating 2, a TPU pearlescent layer 3, a TPU basic color layer 4, a TPU transparent base film layer 5 and an installation adhesive layer 6.
[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
