[0025] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the scope of protection of the present invention.

[0026] Embodiment 1:

[0027] As attached Figures 1 to 4 As shown:

[0028] The present invention provides a car window sunshade and anti-ultraviolet privacy film that is easy to assemble and disassemble, comprising a base layer 11 and an adhesive layer 12, wherein the base layer 11 is made of a high-transmittance PET material, which gives the privacy film good optical transparency, maximizes the clarity of the field of vision in the car, and does not cause obvious interference to the line of sight of people in the car; a polymer nano coating 14 for privacy protection is coated on one side of the base layer 11, and the polymer nano coating 14 can block the outside line of sight, prevent people outside the car from prying into the situation inside the car, and create a private environment for the space inside the car; an adhesive layer 12 is arranged on the side of the polymer nano coating 14 away from the base layer 11, and the thickness of the adhesive layer 12 is between 2.3 and 2.7 mm, and the adhesive layer 12 is a double-sided adhesive This double-sided tape is made of polymer adhesive material, has strong viscosity and good adaptability, can be tightly adhered to the car window glass, and ensures the stability of the privacy film after installation on the car window. On the side of the polymer nano-coating 14 away from the base layer 11, a polymer silicone layer 19 that can be adsorbed and bonded to the car window glass is also provided, and the polymer silicone layer 19 is located below the adhesive layer 12. The polymer silicone layer 19 can also form a reliable adsorption and bonding effect with the surface of the car window glass, further enhancing the firmness of the connection between the privacy film and the car window, and also making the installation process of the privacy film on the car window more convenient and efficient, without the need for complex installation tools and cumbersome installation steps, thereby improving the user experience.

[0029] When installing the window film, first position the upper adhesive layer 12 and the window glass, and then bond them tightly. The adhesive layer 12 can be firmly attached to the surface of the window glass. Subsequently, with the help of the polymer silicone layer 19 located underneath, the entire window film can be stably adsorbed and bonded to the window glass. During this process, there is no need to perform the tedious and complicated wiping and venting process like the installation of traditional window privacy films, which simplifies the entire operation steps and improves installation efficiency.

[0030] Please refer to Figure 2As shown, a protective layer is provided on one side of the base layer 11 away from the polymer nano coating 14, and the protective layer has multiple protective functions, and an anti-scratch coating 15 is further provided on the other side of the protective layer. The hardness of the anti-scratch coating 15 is between 2 and 3H, so that it can effectively resist various scratches in daily use scenarios, such as frictional contact between the window and external dust particles and tiny impurities during frequent lifting and lowering, or inadvertent wiping and touching of the film surface by cleaning tools during vehicle washing, or slight scratches with other objects caused by some accidental collisions during daily use. The anti-scratch coating 15 can rely on its stable and reliable hardness performance to block these external forces from causing damage to the surface of the window film, thereby avoiding scratches on the surface of the window film, ensuring that the view inside the car can remain clear, and will not be blurred or deformed due to scratches on the film surface to affect the user's driving vision. At the same time, it can also maintain the smoothness and beauty of the surface of the window film, so that it can still maintain a good appearance during long-term use, improve the wear resistance of the window film, and extend the service life.

[0031] Please refer to Figure 4 As shown, the protective layer includes an anti-ultraviolet layer 16 and an anti-infrared layer 17, wherein the anti-ultraviolet layer 16 has a blocking effect on ultraviolet rays, and can effectively intercept harmful bands in ultraviolet rays, making it difficult for ultraviolet rays to penetrate the anti-ultraviolet layer 16 and enter the vehicle interior space, thereby protecting the skin of the occupants from health problems such as sunburn, tanning and skin aging caused by long-term exposure to ultraviolet rays; at the same time, it also reduces the aging and fading of the interior decorative materials caused by ultraviolet erosion, maintains the beauty and texture of the interior, and prolongs the service life of the interior; and the anti-infrared layer 17 is used for infrared The barrier can effectively block the transmission of infrared rays into the car. When the vehicle is in direct sunlight or a high temperature environment, the amount of infrared rays entering the car is significantly reduced, thereby effectively reducing the temperature rise caused by the accumulation of infrared heat in the car, so that the car can maintain a relatively cool and comfortable ambient temperature, thereby improving the comfort experience of the drivers and passengers in the car; one side of the base layer 11 is tightly stacked with an infrared protection layer 16, an ultraviolet protection layer 17 and an anti-scratch coating 15 in sequence from the inside to the outside. Such a stacked structure enables the functional layers to cooperate with each other and give full play to their respective advantages.

[0032] Please refer to Figure 3 As shown, multiple groups of clay particles are evenly distributed on one side of the polymer nano coating 14, so that the polymer nano coating 14 can be firmly adhered to the base layer 11 through the multiple groups of clay particles. These clay particles have suitable viscosity, which can ensure a reliable connection between the polymer nano coating 14 and the base layer 11, so that the polymer nano coating 14 can be firmly attached to the base layer 11 and will not easily shift or fall off.

[0033] A specific proportion of colorant is mixed in the polymer nano coating 14, wherein the mass of the colorant accounts for 10% to 20% of the total mass of the polymer nano coating 14, so that the polymer nano coating 14 can realize the privacy protection function. When people outside the car window try to observe the interior of the car, the colorant is evenly distributed in the polymer nano coating 14, which will change the characteristics of light passing through the film, making the scene inside the car blurred, thereby effectively blocking the line of sight and preventing people outside the car from spying on the specific situation inside the car, creating a relatively private space environment for users in the car and ensuring the privacy and security of users. Whether in daily driving or when the vehicle is parked, users do not need to worry about privacy leakage in the car and can use the vehicle with peace of mind.

[0034] The components of the colorant are divided by weight, among which the content of carbon black is between 40 and 60 parts. Carbon black, as a pigment component, can give the colorant a deep and rich black tone, which helps to enhance the overall light-shielding and privacy protection performance of the window film, and can improve the color durability to a certain extent; the weight of organic pigments is between 10 and 20 parts. These organic pigments can bring rich and diverse color choices to the colorant, and cooperate with carbon black. Through different proportions, various tones and color effects can be presented to meet the needs of different users for personalized privacy film colors, making the window film more attractive in appearance; the weight of additives is between 5 and 10 parts, which is used to improve the use effect of the window film; the weight of the carrier is between 10 and 30 parts, which is used to provide a stable processing environment for each component and ensure the quality of the window film.

[0035] The organic pigment is phthalocyanine blue or azo red. Phthalocyanine blue or azo red is known for its excellent color brightness, good light resistance and chemical stability. It can give the colorant a corresponding color tone, and can improve the color saturation and visual effect in the polymer nano coating 14. At the same time, its stable chemical structure enables it to maintain color durability under various environmental conditions and is not easy to fade or change color; the additives include dispersants, stabilizers and plasticizers. The dispersant can ensure that the carbon black and the various components of the organic pigment are evenly dispersed in the colorant to avoid the phenomenon of pigment agglomeration and ensure the consistency and uniformity of the color. The stabilizer can prevent the colorant from chemically reacting or physically reacting during long-term storage or under different environmental conditions. The plasticizer can adjust the flexibility and plasticity of the colorant, so that it can be better integrated with the polymer nano coating 14, and improve the overall processing performance and use effect; the carrier has the function of basic bearing and dispersion medium in the whole colorant system, and it can be selected from organic solvents or resins. The organic solvent can fully dissolve and mix the carbon black, organic pigments and additives with its good solubility and volatility, which is convenient for the uniform dispersion and processing operation of each component in the preparation process, and affects the drying speed and film-forming performance of the colorant to a certain extent; when the resin is selected as the carrier, it can provide a more stable physical support for the colorant by virtue of its own polymer structure characteristics.

[0036] The specific usage and function of this embodiment are as follows: when installing the window film, first take out the window film and prepare the window glass surface to ensure that it is clean and free of impurities. Then, the upper surface of the adhesive layer 12 is lightly contacted with the top edge of the window glass and begins to fit. Press slightly to make the adhesive layer 12 initially bonded to the window glass. Afterwards, with the help of the polymer silicone layer 19 located below the adhesive layer 12, the polymer silicone layer 19 can be adsorbed and bonded to the window glass. Starting from the top of the window glass, it is slowly and evenly pushed downward under the action of its own gravity, so that the entire polymer silicone layer 19 is tightly adsorbed to the window glass until the entire window film is completely bonded to the window glass. The entire process does not require complicated water spraying, wiping and exhaust operations, which simplifies the installation process and improves installation efficiency.

[0037] The anti-ultraviolet layer 16 in the protective layer can block a large amount of ultraviolet rays. Long-term exposure to ultraviolet rays will cause sunburn and tanning to the skin of people in the car, and will also cause aging and fading of decorative materials in the car. The anti-ultraviolet layer 16 can effectively reduce these risks; and the anti-infrared layer 17 in the protective layer can reduce the entry of infrared rays into the car. Infrared rays are an important carrier of heat transfer. Reducing the entry of infrared rays can significantly reduce the temperature in the car, especially in hot summer. It can effectively reduce the load of the vehicle's air-conditioning system, improve the comfort in the car, and create a relatively cool and comfortable environment for the car.

[0038] The anti-scratch coating 15 is located on the outside of the window film and has a hardness of 2 to 3H. In daily use, the windows are often raised and lowered, and come into contact with dust, sand and other impurities from the outside. When cleaning the windows, they are also wiped by cleaning tools. The anti-scratch coating 15 can effectively resist these scratches, prevent the film surface from being scratched, and keep the film surface smooth and flat, which not only ensures good visual clarity, but also maintains the beauty of the privacy film, improves the wear resistance and service life of the privacy film, reduces the frequency of replacement due to scratches, and reduces the cost of use.

[0039] The base layer 11 is made of high-transmittance PET material, which provides a stable basic support structure for the entire window film and ensures the shape and strength of the film; the polymer nano coating 14 is adhered to the base layer 11 through multiple groups of clay particles, and a colorant is mixed in the polymer nano coating 14, so that the polymer nano coating 14 can achieve a privacy protection function. When people outside the window try to observe the interior of the car, the colorant is evenly distributed in the polymer nano coating 14, which will change the characteristics of light passing through the film, making the scene inside the car blurred, thereby effectively blocking the line of sight and improving privacy.
