Description

Technical Field

[0001] This utility model relates to the field of glass film technology, and in particular to a heat-insulating window film for automobiles. Background Technology

[0002] With the continuous increase in car ownership and people's growing demands for driving safety and comfort, car window tinting has become an important part of car decoration and functional enhancement. In daily driving scenarios, glare problems bring many troubles and safety hazards to drivers. For example, when driving at night, the direct glare from the high beams of oncoming vehicles often causes drivers to momentarily fall into a blind spot, making it difficult to clearly distinguish road conditions ahead, such as potholes, the curvature of curves, and whether there are pedestrians or obstacles on the roadside.

[0003] Traditional automotive window films rely solely on simple light-blocking or light-absorbing principles to reduce light intensity, failing to address glare issues. When exposed to strong sunlight, they not only fail to effectively disperse and weaken glare but may also exacerbate glare interference with the driver's vision due to irregular reflection and refraction of light within the film layer. Therefore, a new type of automotive window film is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a heat-insulating window film for automobiles, which aims to improve the problem of the lack of effective anti-glare design in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating window film for automobiles, comprising an anti-scratch coating, an anti-glare layer adhered to the inner wall of the anti-scratch coating, a heat insulation layer fixedly connected to the inner wall of the anti-glare layer, a substrate layer fixedly connected to the inner wall of the heat insulation layer, an adhesive layer adhered to the inner wall of the substrate layer, a protective film adhered to the inner wall of the adhesive layer, and an anti-fouling coating, a nano-prism coating, an anti-reflective coating, and a weather-resistant protective coating fixedly connected sequentially from the outside to the inside of the anti-glare layer.

[0006] As a further description of the above technical solution:

[0007] The nanoprism coating is composed of multiple prism units with a height of 20nm to 50nm and a bottom diameter of 10nm to 30nm. Each unit is arranged in a regular pattern with a spacing of 5nm to 15nm.

[0008] As a further description of the above technical solution:

[0009] The scratch-resistant coating consists of a diamond-like carbon coating with a thickness of 1 mm to 3 mm.

[0010] As a further description of the above technical solution:

[0011] The heat insulation layer is a composite layer containing nano-ceramic particles with a particle size ranging from 10 nm to 100 nm.

[0012] As a further description of the above technical solution:

[0013] The substrate layer is made of polyester material and has a thickness of 20 nm to 50 nm.

[0014] As a further description of the above technical solution:

[0015] The adhesive layer is made of polyurethane adhesive and has a thickness ranging from 5 nm to 15 nm.

[0016] As a further description of the above technical solution:

[0017] The weather-resistant protective coating is made by UV-curing paint and has a thickness of 2 nm to 5 nm.

[0018] As a further description of the above technical solution:

[0019] The antireflective coating is made of a fluorosiloxane-containing polymer material with a thickness of 1 nm to 3 nm.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, the nano-prism coating in the anti-glare layer effectively disperses and weakens glare through multiple refractions and scattering when light is incident. This prevents the driver's vision from being obstructed by strong light, reducing visual fatigue and eye discomfort caused by glare, and greatly improving driving safety and comfort.

[0027] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 This utility model provides an embodiment of an automotive heat-insulating window film, comprising an anti-scratch coating 1, which effectively resists external mechanical scratches and improves the durability of the heat-insulating window film. An anti-glare layer 2 is adhered to the inner wall of the anti-scratch coating 1. The multi-functional layered design of the anti-glare layer 2 enables light adjustment and glare control. A heat-insulating layer 3 is fixedly connected to the inner wall of the anti-glare layer 2. The heat-insulating layer 3 has excellent infrared reflection and heat blocking performance, which can effectively reduce the temperature inside the vehicle. A substrate layer 4 is fixedly connected to the inner wall of the heat-insulating layer 3. The substrate layer 4 provides structural stability and ensures the overall performance of the film. An adhesive layer 5 is attached to the inner wall of the substrate layer 4, which achieves a firm adhesion to the window glass and enhances the safety of the window film. A protective film 6 is attached to the inner wall of the adhesive layer 5. The protective film 6 can be removed after the window film is installed to protect the integrity of the window film during transportation and installation. The anti-glare layer 2 is fixedly connected from the outside to the inside with an anti-fouling coating 7, a nano-prism coating 8, an anti-reflective coating 9, and a weather-resistant protective coating 10.

[0029] Reference Figures 1-3 The nanoprism coating 8 consists of multiple prism units with heights ranging from 20nm to 50nm and bottom diameters from 10nm to 30nm. Each unit is arranged regularly with a spacing of 5nm to 15nm. The prism structure of the nanoprism coating 8 can effectively reduce glare interference with the driver's vision through multiple refractions and scattering of light, while maintaining high light transmittance and improving the driving experience. The regularly arranged prism units further enhance the uniformity of optical performance and avoid visual distortion caused by light focusing.

[0030] Reference Figure 2 The scratch-resistant coating 1 is composed of a diamond-like carbon coating with a thickness of 1mm to 3mm. The diamond-like carbon material of the scratch-resistant coating 1 has high hardness and high wear resistance, which can effectively protect the surface of the window film from scratches and extend its service life.

[0031] Reference Figure 2 The heat insulation layer 3 is a composite layer containing nano-ceramic particles with a particle size ranging from 10nm to 100nm. The heat insulation layer 3 significantly reduces the interior temperature of the vehicle and improves the energy utilization efficiency of the vehicle through the efficient infrared reflection performance of the nano-ceramic particles.

[0032] Reference Figure 2 The substrate layer 4 is made of polyester material with a thickness of 20nm to 50nm. The polyester material of the substrate layer 4 has excellent mechanical strength and flexibility, which can provide stable support for the overall film layer.

[0033] Reference Figure 2 The adhesive layer 5 is made of polyurethane adhesive with a thickness ranging from 5nm to 15nm. The polyurethane adhesive in the adhesive layer 5 can maintain stable adhesion performance under different temperature and humidity environments, ensuring a tight bond between the window film and the car window glass.

[0034] Reference Figure 3 The weather-resistant protective coating 10 is made of UV-cured coating and has a thickness of 2nm to 5nm. The weather-resistant protective coating 10 can resist the effects of ultraviolet rays, moisture and temperature changes, and extend the service life of the anti-glare layer 2 and the heat insulation layer 3.

[0035] Reference Figure 3 The antireflective coating 9 is made of a polymer material containing fluorosiloxane and has a thickness of 1 nm to 3 nm. The antireflective coating 9 can significantly reduce the reflectivity of light and increase the transmittance of visible light, thereby enhancing the clarity of the in-vehicle vision.

[0036] Working principle: When applying film to car windows, peel off one end of the cut heat-insulating window film from the protective film 6, align the peeled end with the top edge of the window glass, and slowly apply the window film to the glass. At the same time, use a squeegee to scrape downwards from the top of the window film with even force to gradually squeeze out the air and excess installation fluid between the window film and the glass, so that the window film adheres tightly to the glass surface.

[0037] While the car is in motion, the scratch-resistant coating 1 protects against everyday elements such as wind, sand, and tree branches. When light is incident, the prism units in the nano-prism coating 8 cause multiple refractions and scatterings of the light, effectively dispersing and weakening glare. Meanwhile, the anti-reflective coating 9 reduces light reflectivity and increases visible light transmittance. A further weather-resistant protective coating 10 effectively blocks the erosion of the internal anti-glare layer 2 and heat insulation layer 3 by ultraviolet rays, moisture, and temperature changes. Simultaneously, the nano-ceramic particles in the heat insulation layer 3 reflect a large amount of this glare back, preventing heat from entering the vehicle interior.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
