[0002] The car body color-changing film changes the appearance of the entire car or part of it by covering and pasting it as a whole. The car body color-changing film is mainly attached to the surface of the car body through high molecular polymer materials and is easy to remove. In recent years, the mainstream car body color-changing film products include transparent film, automotive electroplating film, pearlescent film, glossy film, matte film, painted film, leather texture film, brushed film, electroplating film, electro-optical metal film and matte metal film.
[0003] Existing patent publication number CN215480696U proposes a casting-grade vehicle body color-changing film. By configuring the film body, an isolation layer, an adhesive layer, a flame-retardant layer, a base layer, a heat-insulating layer, a wear-resistant layer, an anti-scratch layer, a UV protection layer, a transparent fiberglass film layer, and a coating, the film's scratch resistance, wear resistance, UV resistance, and heat insulation properties are enhanced. However, the film still has certain drawbacks: for example, during vehicle use, the film body is easily contaminated with dust due to electrostatic adsorption, resulting in dirt on the film body and affecting the overall aesthetics of the vehicle.
[0004] Therefore, a PVC color-changing car cover film structure is needed to solve the above problems. Utility Model Content

To this end, the present invention proposes a PVC color-changing car cover film structure to prevent dust from being adsorbed on the car cover film due to static electricity during vehicle use, thereby affecting the overall appearance of the vehicle. The present invention provides a transparent anti-static protective coating, which can wrap and protect the transparent heat-insulating layer, the self-repairing coating, and the colored layer. Therefore, when the car cover film is applied to the vehicle, it can effectively avoid the adsorption of dust due to static electricity, thereby improving the overall appearance of the vehicle.
[0006] To achieve the above-mentioned purpose, the first aspect of the present invention provides a PVC color-changing car cover film structure, comprising a transparent antistatic protective coating and a transparent heat-insulating layer, a self-repairing coating, a colored layer, an adhesive layer and a release film layer that are compositely connected in sequence from top to bottom;
[0007] The transparent antistatic protective coating has a wrapping chamber with an open bottom, the transparent heat-insulating layer, the self-repairing coating, and the colored layer are all arranged in the wrapping chamber, and the colored layer is flush with the lower surface of the transparent antistatic protective coating;
[0008] The release film layer is connected to the colored layer and the transparent antistatic protective coating through the adhesive layer.
[0009] Furthermore, the transparent antistatic protective coating is coated with a colorless and transparent antistatic coating.
[0010] Furthermore, the transparent heat-insulating layer is configured as a transparent glass fiber layer.
[0011] Furthermore, the transparent heat-insulating layer has a recessed portion in the middle portion for increasing the contact area with the external heat source.
[0012] Furthermore, the cross section of the recessed portion is configured to be thick at both ends and thin in the middle.
[0013] Furthermore, the recessed portion is configured as a spherical arc structure.
[0014] Furthermore, the adhesive layer is a pressure-sensitive adhesive.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] By setting a transparent anti-static protective coating, and the transparent anti-static protective coating has a wrapping chamber to wrap the transparent insulation layer, self-repairing coating and colored layer, when the color-changing car cover film is affixed to the vehicle through the adhesive layer and the release film layer, the transparent anti-static protective coating can effectively prevent static electricity caused by external factors, so that dust will not be adsorbed on the surface of the color-changing car cover film due to static electricity, thereby ensuring that the appearance of the vehicle can remain clean for a long time, thereby achieving the purpose of improving the overall aesthetics of the vehicle.
[0017] In addition, a transparent heat-insulating layer is provided to isolate the colored layer from the influence of the external temperature, preventing the colored layer from turning yellow due to temperature reasons, thereby avoiding discoloration of the color-changing car cover film and extending the service life of the color-changing car cover film.
[0018] Furthermore, by using colorless and transparent antistatic coating to form a transparent antistatic protective coating, since the colorless and transparent antistatic coating is composed of polymer compounds and has the characteristics of obvious antistatic effect, wear resistance, green and pollution-free, and easy to use, it has the effect of wear resistance, so it can further effectively extend the service life of the color-changing car cover film.
[0019] In addition, since the transparent heat-insulating layer has a concave portion with a spherical arc structure, it can effectively increase the contact area between it and the external heat source, thereby further improving its heat-insulating performance and achieving a better protection effect on the colored layer.

[0024] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1 The first embodiment of the utility model provides a PVC color-changing car cover film structure, including a transparent anti-static protective coating 1 and a transparent heat-insulating layer 2, a self-repairing coating 3, a colored layer 4, an adhesive layer 5 and a release film layer 6 that are compositely connected in sequence from top to bottom.
[0026] In this embodiment, the transparent antistatic protective coating 1 has a wrapping chamber with an opening at the bottom, and the transparent heat-insulating layer 2, the self-repairing coating 3 and the colored layer 4 are all arranged in the wrapping chamber, so that the transparent antistatic protective coating 1 can wrap the transparent heat-insulating layer 2, the self-repairing coating 3 and the colored layer 4, and complete the bonding to the vehicle surface through the adhesive layer 5 and the release film layer 6, so it can effectively prevent the outer surface of the color-changing car cover film structure from dust adsorption due to static electricity, thereby ensuring that the color-changing car cover film structure is always in a clean state, so it can effectively improve the overall aesthetics of the vehicle.
[0027] The colored layer 4 is flush with the lower surface of the transparent antistatic protective coating 1 to ensure the smoothness of the subsequent adhesive layer 5 and release film layer 6 when they are laid.
[0028] It should be noted that the release film layer 6 is connected to the colored layer 4 and the transparent antistatic protective coating 1 through the adhesive layer 5, so as to be used for subsequently covering and bonding the color-changing car cover film structure to the vehicle surface.
[0029] This device is provided with a transparent antistatic protective coating 1, and the transparent antistatic protective coating 1 has a wrapping chamber to wrap the transparent heat-insulating layer 2, the self-repairing coating 3 and the colored layer 4. Therefore, when the color-changing car cover film is affixed to the vehicle through the adhesive layer 5 and the release film layer 6, the transparent antistatic protective coating 1 can effectively prevent static electricity caused by external factors, so that dust will not be adsorbed on the surface of the color-changing car cover film due to static electricity, thereby ensuring that the appearance of the vehicle can remain clean for a long time, thereby achieving the purpose of improving the overall aesthetics of the vehicle.
[0030] In addition, a transparent heat-insulating layer 2 is provided to isolate the colored layer 4 from the influence of the external temperature, thereby preventing the colored layer 4 from turning yellow due to temperature reasons, thereby avoiding discoloration of the color-changing car cover film and extending the service life of the color-changing car cover film.
[0031] In this embodiment, the transparent antistatic protective coating 1 is coated with a colorless transparent antistatic paint. The transparent antistatic protective coating 1 is formed by coating with a colorless transparent antistatic paint. Since the colorless transparent antistatic paint is polymerized by high molecular compounds and has the characteristics of obvious antistatic effect, wear resistance, green and pollution-free, and easy to use, it has the effect of wear resistance, so it can further effectively extend the service life of the color-changing car cover film.
[0032] In other embodiments, the transparent heat-insulating layer 2 is configured as a transparent glass fiber layer. Since transparent glass fiber has a better heat-insulating effect, it can improve the heat-insulating capacity of the color-changing car cover film.
[0033] In a further embodiment, the transparent heat-insulating layer 2 has a recessed portion in the middle thereof, so as to increase the contact area with the external heat source and improve the heat-insulating effect.
[0034] Specifically, the cross section of the recessed portion is configured to be thick at both ends and thin in the middle.
[0035] Preferably, the recessed portion is configured as a spherical arc structure, so that the contact area between the recessed portion and the external heat source can be effectively increased, thereby further improving the heat insulation performance and achieving a better protection effect on the colored layer 4.
[0036] In this embodiment, the adhesive layer 5 is a pressure-sensitive adhesive.
[0037] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
