Description

Technical Field

[0001] This utility model relates to the field of automotive films, and in particular to a high-barrier, antioxidant automotive film. Background Technology

[0002] Automobiles are a means of transportation that shortens the perceived distance between cities and has a significant impact on the economic and cultural development of modern society. With economic development, people increasingly pursue fashion and trends, placing greater emphasis on the appearance of their cars. This has led to the emergence of various types of car films. Car films are applied to the surface of the car paint, protecting the original paint and decorating the vehicle body. To improve practical performance, existing car films sometimes add an anti-UV layer to enhance their UV protection and an abrasion-resistant layer to improve their wear resistance. However, their overall performance is relatively poor, making it difficult to comprehensively improve the film's effectiveness. For example, while improving UV protection, it's difficult to comprehensively improve the film's ability to block infrared rays and glare, which can easily affect its performance. Furthermore, existing car films have poor oxidation resistance, making them susceptible to environmental factors that accelerate aging, such as discoloration and cracking, significantly shortening their lifespan. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a high-barrier anti-oxidation car film to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-barrier antioxidant car film, comprising a car film body, wherein an antioxidant coating is provided on the upper surface of the car film body, an acrylic resin coating is coated on the upper surface of the antioxidant coating, and a barrier layer is provided on the acrylic resin coating.

[0005] The barrier layer includes a zinc oxide coating disposed on an acrylic resin coating and a nano-ceramic coating coated on the zinc oxide coating, wherein a number of nano-silver particles are embedded in the nano-ceramic coating.

[0006] Preferably, the upper surface of the nano-ceramic coating is coated with a protective coating.

[0007] Preferably, the protective coating is a nano-silica coating material.

[0008] Preferably, the zinc oxide coating is bonded to the upper surface of the acrylic resin coating by an adhesive layer.

[0009] Preferably, the nano-silver particles in the nano-ceramic coating are distributed at equal intervals.

[0010] The beneficial effects of this utility model are:

[0011] This invention effectively improves the glare blocking effect of the car film by setting a zinc oxide coating, while the nano silver particles have high reflectivity and can effectively reflect infrared rays, reducing the penetration of infrared rays and thus lowering the temperature inside the car. The nano ceramic coating improves the ultraviolet blocking effect of the car film, thereby comprehensively improving the use effect of the car film. The antioxidant coating and acrylic resin coating improve the antioxidant performance of the car film, reduce the aging rate of the car film affected by external environmental factors, and help to extend the service life of the car film.

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] like Figure 1 As shown, this utility model provides a high-barrier, antioxidant car film, including a car film body 1;

[0017] In this embodiment, the car film body 1 is made of PET material, which has high transparency and good heat insulation effect;

[0018] like Figure 1 and Figure 2 As shown, in this embodiment, an antioxidant coating 2 is provided on the upper surface of the car film body 1 to improve the antioxidant effect of the car film. An acrylic resin coating 3 is uniformly coated on the upper surface of the antioxidant coating 2, and a barrier layer 4 is provided on the acrylic resin coating 3.

[0019] The barrier layer 4 includes a zinc oxide coating 41 disposed on the acrylic resin coating 3 and a nano-ceramic coating 42 uniformly coated on the upper surface of the zinc oxide coating 41. Several nano-silver particles 43 are fixedly embedded inside the nano-ceramic coating 42, and the nano-ceramic coating 42 completely covers each nano-silver particle 43, reducing the shedding of the nano-silver particles 43.

[0020] Acrylic resin coating 3: High oxidation resistance, high transparency, and chemical resistance, which can effectively provide oxidation protection for the car film body 1 and also effectively reduce the erosion of the car film body 1 by external corrosive objects;

[0021] Among them, the nano-silver particles 43 in the nano-ceramic coating 42 are distributed at equal intervals, which can reflect infrared rays more uniformly and effectively.

[0022] In this embodiment, the upper surface of the nano-ceramic coating 42 is coated with a protective coating 6, which provides enhanced protection for the car film and improves the performance of the car film.

[0023] In this embodiment, the protective coating 6 is made of nano-silica material, which has extremely high hardness and can effectively prevent scratches and wear on the surface of the car film. It also has good hydrophobicity and oleophobicity, which can reduce the adhesion of dirt and keep the car film clean.

[0024] In this embodiment, the zinc oxide coating 41 is bonded to the upper surface of the acrylic resin coating 3 by the adhesive layer 5, thereby improving the stability of the zinc oxide coating 41 bonded to the acrylic resin coating 3.

[0025] Specifically, the zinc oxide coating has high reflectivity and partial absorption properties, which can effectively reduce light transmission and reflection, thereby reducing glare and improving the glare blocking effect of the car film. The nano-ceramic coating 42 has excellent optical properties, which can effectively reflect the ultraviolet part of sunlight, while maintaining a high visible light transmittance, thereby improving the ultraviolet blocking effect of the car film. The nano-silver particles 43 have high reflectivity, which can effectively reflect infrared rays, so that the car film can effectively block the penetration of infrared rays, thereby reducing the temperature inside the car. Furthermore, the nano-silver particles 43 have a high transmittance of visible light and will not significantly affect the light transmittance and appearance of the car film.
