Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a high-efficiency self-adhesive automobile solar film and a preparation method thereof. Background Art

[0002] In many key areas of the modern automobile industry, such as automobile safety systems, interior protection, and improved driving comfort, extremely demanding requirements are placed on the performance of solar films. The existing automobile solar films have many shortcomings during use, such as the generation of odor in the car after long-term use, the cumbersome replacement process, the possibility of damaging the silver-painted antenna on the rear windshield, the communication module of the GPS radio and the automatic collision avoidance system, and the proneness to bubbles. These problems not only affect the appearance of the car, but may also affect the signal reception and driving safety in the car. Obviously, traditional solar films are gradually unable to meet the growing demand in terms of UV protection, durability, and ease of use.

[0003] Although there are patent documents that have studied and improved the above problems, such as CN214354635U discloses a car anti-ultraviolet solar film, which includes a multi-layer structure, and provides high anti-ultraviolet and anti-wear performance through the cooperation between the inner protective film layer, the anti-ultraviolet layer, the outer protective film layer and the anti-scratch and wear-resistant layer. However, this design may have some limitations in practical applications, such as the multi-layer structure may increase costs, and may require more time and skills during the installation process.

[0004] Therefore, in view of the technical improvement of the existing solar film, the present invention provides a high-efficiency self-adhesive automobile solar film, which realizes quick installation and high durability by simplifying the structure and optimizing the materials, while maintaining excellent anti-ultraviolet performance. The manufacturing method is relatively simple, which reduces the production cost to a certain extent and improves the production efficiency. While providing the necessary protection performance, the high-efficiency self-adhesive automobile solar film of the present invention also has the advantages of easy operation, environmental protection and pollution-free, antenna protection and recyclability, so it has important strategic significance and broad application prospects in the field of automobile solar films. Summary of the invention

[0005] The purpose of the present invention is to provide a self-adhesive car solar film to solve the problems of complicated operation, easy generation of bubbles, odor in the car, damage to printed antennas and waste of resources in the prior art. By using ultra-thin glass material or ultra-thin hard material, and a film design customized according to the shape of the car glass, the technical effects of fast self-adhesion, no bubbles, antenna protection, environmental protection, no pollution and recyclability are achieved.

[0006] To achieve the above object, the present invention proposes the following technical solutions: The self-adhesive automobile solar film of the present invention comprises a solar film body made of ultra-thin glass material or ultra-thin hard material. The solar film body has a self-adhesive design and can be directly adhered to the automobile glass surface.

[0007] In view of claim 2, the solar film body is designed to start from the black lace border of the front windshield and the rear windshield, and the diaphragms of the front windshield and the rear windshield are composed of two symmetrical glass solar films. The diaphragm is designed to go from the black lace border of the front windshield of the car to the microwave window, and the black lace border of the rear windshield to the printed silver paint antenna, and bypass the key components, and then split into two from the middle to form a complete solar film. In order to better adapt to the curved surface of the glass and ensure the accuracy of the film, the diaphragm is split into two from the middle. The split design allows the solar film to fit the glass surface more flexibly and reduce the generation of bubbles and wrinkles.

[0008] Furthermore, the solar film for the front and rear windshields consists of two symmetrical films, which helps ensure that the solar film fits the glass perfectly while maintaining a consistent and aesthetic appearance. The films are designed with key components on the car glass in mind, such as the microwave window of the front windshield, the base of the rearview mirror, and the silver-painted antenna of the rear windshield. The cut and shape of the film are designed to precisely bypass these components, avoiding any interference or damage to them during installation.

[0009] Preferably, with respect to claim 3, the solar film of the rear windshield is specially designed to have no microwave window and to have a rear brake light base, and the solar film goes around the black lace and is divided into two in the middle to form a whole sheet.

[0010] With respect to claim 4, the solar film of the front and rear side window glasses is designed with the flat glass seen after the automobile glass is fully raised as the target, so as to be directly bonded.

[0011] Preferably, for claim 5, the preparation method of the self-adhesive automobile solar film of the present invention has three key features and steps. First, the raw materials are selected. The first step of the preparation method is to select film-making raw materials with properties such as heat insulation, UV protection, and durability. These properties are crucial to the performance of the solar film and can effectively improve the comfort in the car and protect the equipment in the car. When selecting raw materials, the environmental protection and recyclability of the materials must also be considered to meet the strict requirements of the modern automobile industry for environmental protection and reduce the impact on the environment. Then customize the film and use precision cutting technology to customize the solar film according to the glass size and shape of various models. Ensure that the solar film can perfectly fit the glass of different models, whether it is standard shape or special shape. Further expand the scope of application of the solar film, the process of customizing the film involves high-precision manufacturing technology to meet the specific needs of various models, and improve the applicability and user experience of the solar film. Finally, the film is divided and self-bonded, and the customized film is divided into two from the middle so that it can be bonded to both sides of the glass. The design allows the solar film to bypass specific parts on the glass, such as the microwave window, rearview mirror base, silver painted antenna and rear brake light base, avoiding interference and damage to these parts during the application process.

[0012] Furthermore, the hardness and rigidity of the solar film material enable it to have a self-adhesive effect, and it can automatically and tightly adhere to the glass surface without the need for additional tools and technical assistance. The self-adhesive ability reduces the bubbles that may appear during the film application process, ensures seamless contact between the solar film and the glass, and improves the overall quality and effect of the film application. Furthermore, through these steps, the preparation method of the present invention can produce a high-performance, environmentally friendly, easy-to-use self-adhesive automotive solar film, which meets the comprehensive requirements of the modern automotive industry for solar films and has broad application prospects.

[0013] The self-adhesive car solar film described in claim 6 has an easily peelable surface film layer, which significantly simplifies the film application process. The user can directly tear off this film layer and then align it with the glass surface for application. This easy-to-use design means that the user can complete the film application without professional knowledge or special tools, which greatly reduces the technical threshold for film application and makes it easy for ordinary consumers to operate.

[0014] Furthermore, it helps to reduce possible errors in the film application process, such as bubbles and wrinkles, thereby improving the success rate of film application and the final effect. Through this innovation of easy-to-peel surface film layer, the solar film of the present invention provides a more convenient and user-friendly film application solution, making the film application process more efficient and accurate, while also reducing dependence on professional installation services, providing greater convenience for users.

[0015] Preferably, with respect to claim 7, the solar film is tailor-made for a specific car model, and each piece of solar film perfectly matches the glass size and shape of the corresponding car model. The user does not need to perform additional cutting of the solar film, as the solar film has been pre-cut according to the glass size of the specific car model.

[0016] Preferably, during the installation of traditional solar films, it is often necessary to use heating tools such as a baking gun to adjust the shape of the film to ensure that it can fit the curve of the glass. However, since the solar film of the present invention is designed for a specific car and has a preset suitable shape, this step is omitted. Furthermore, since the solar film has a preset suitable shape, the user can directly stick it on the car glass, which greatly reduces the risk of installation failure due to improper cutting or baking. Furthermore, omitting the cutting and baking steps not only simplifies the installation process, but also improves the efficiency of film application, allowing users to quickly complete the film application work.

[0017] With respect to claim 8, the raw materials and manufacturing processes used in the production process of the self-adhesive car solar film ensure that no odor is generated during use, avoiding the problem of traditional solar films releasing volatile organic compounds (VOCs) after a period of use, causing air pollution in the car. This is consistent with the characteristics of high-quality films mentioned in some materials. Even after being exposed to the sun, high-quality films will not emit volatile gases that are harmful to the human body, while the residual solvents in the adhesive layer of low-quality car films have a high benzene content and may have odors that affect the health of car owners. Furthermore, due to the self-adhesive properties of the solar film, bubbles are not easily generated during the film application process, which ensures the durability, overall quality and effect of the solar film, while avoiding the problems of blistering and cracking.

[0018] Preferably, with respect to claim 9, the self-adhesive car solar film has the function of protecting the printed silver wire antenna, GPS radio and automatic anti-collision system on the rear windshield, which is a significant improvement compared with the traditional solar film. The traditional solar film may damage these sensitive antenna elements during the installation process, while the solar film of the present invention ensures that these key components will not be damaged during the film application process through precise cutting and bonding technology. The solar film can perfectly fit the glass, and at the same time cleverly prevents the problem of tearing off the silver paint antenna when replacing due to over-tight bonding, thereby maintaining the quality of signal reception in the car and avoiding the antenna damage and signal interference problems that may be caused by the traditional film application method. Maintain the quality of signal reception in the car and avoid affecting the normal use of electronic equipment in the car. Furthermore, the self-adhesive property of this solar film also helps to avoid the generation of bubbles during the film application process, thereby ensuring the durability of the solar film and the overall quality and effect. Not only the performance of the solar film is improved, but also its protective effect on sensitive electronic equipment in the car is enhanced, so that the solar film of the present invention has important application value in the field of automotive accessories.

[0019] According to claim 10, the waste solar film replaced by the self-adhesive automobile solar film is made of recyclable materials. When the solar film reaches the end of its service life and needs to be replaced, it can be recycled and reprocessed, thereby reducing resource waste and environmental pollution.

[0020] Through the above technical solution, the present invention provides a self-adhesive car solar film, which can not only be quickly self-adhesive on various car glasses, but also remain free of bubbles and odors after long-term use, while protecting the signal reception of the antenna in the car, and has the characteristics of environmental protection and recyclability. This design makes the solar film have significant advantages in car beauty and protection, and is suitable for glass films of various models, with broad application prospects.

[0021] The above technical solution can achieve the following beneficial effects: Compared with the prior art, the present invention has the following advantages and positive effects: (1) The present invention provides a self-adhesive car solar film, which is customized according to the glass size and shape of a specific car model, ensuring precise adhesion to the car glass. Users do not need to perform additional cutting or heating treatment, and can directly apply the film, greatly improving installation efficiency.

[0022] (2) The solar film provided by the present invention is made of ultra-thin hard material with high elastic modulus and is designed to adapt to the glass shape of different car models, which significantly increases the equivalent coverage area of ​​the solar film. This not only improves the stability of the solar film when subjected to external forces, thereby enhancing its durability, but also ensures the mechanical strength and reliability of the solar film under high impact conditions.

[0023] (3) The solar film provided by the present invention is made of environmentally friendly materials, ensuring that the solar film does not generate odor during use and avoiding the release of volatile organic compounds, thereby maintaining the cleanliness of the air in the car and protecting the health of the passengers. The self-adhesive property reduces the generation of bubbles and odor, further improving the accuracy and reliability of the film.

[0024] (4) The solar film design of the present invention allows the replaced waste solar film to be recycled and reused, thereby reducing resource waste and meeting environmental protection requirements. This design not only improves the environmental performance of the solar film, but also simplifies the processing process of waste solar film and improves the recycling rate of resources.

[0025] (5) The solar film of the present invention adopts an easy-to-peel surface film design, allowing the user to directly tear off the surface film layer and stick it on the glass surface without the need for professional knowledge or the use of other tools, thereby simplifying the film application process and providing a more convenient and user-friendly film application solution.

[0031] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0032] Figure 1 The invention shows a schematic diagram of the relationship between the shape customization and installation position of the windshield solar film provided by the present invention. The figure details the customized shapes and installation positions of the front windshield solar film (1), the front side window glass solar film (2), the rear side window glass solar film (3), the triangular area glass solar film (4) and the rear windshield glass solar film (5). These films are customized according to the specific shape of the automobile glass to ensure perfect fit.

[0033] Figure 2 The schematic diagram of the structure of the self-adhesive car solar film windshield is shown. As can be seen in the figure, the design of the windshield solar film (1) takes into account the position of the microwave window and the rearview mirror base. Through precise cutting and self-adhesive technology, it is ensured that the solar film can perfectly fit the windshield while avoiding interference with these key components.

[0034] Figure 3 The schematic diagram of the structure of the self-adhesive automobile solar film rear windshield is shown. Similar to the front windshield, the rear windshield solar film (5) also uses precise cutting and self-adhesive technology to adapt to the shape and structure of the rear windshield, especially considering the characteristics of the rear windshield without a microwave window and with a rear brake light base. In a specific embodiment, firstly, according to the shape and size of the automobile glass, the film-making raw materials with heat insulation, UV protection, durability and other characteristics are selected, and the requirements of environmental protection and recyclability are taken into consideration. Then, the film is customized according to the shape of the automobile glass using precise cutting technology.

[0035] In the traditional film application method, the printed silver paint antenna on the rear windshield may be damaged after long-term use. This is because the glue layer of the traditional solar film may be oxidized after installation, resulting in the glue from the old film remaining on the silver paint antenna when replacing it, and the antenna may even be torn off when the old film is torn off, thus damaging the antenna. This situation not only affects the signal reception quality in the car, but may also require professional repair or replacement of the glass, adding additional costs and inconvenience.

[0036] In contrast, the self-adhesive car solar film of the present invention fully considers the protection of the printed silver wire antenna on the rear windshield. Through precise cutting and self-adhesion technology, the solar film can perfectly fit the glass while avoiding the antenna area and will not damage the antenna. This design not only maintains the signal reception quality in the car and avoids affecting the normal use of electronic equipment in the car, but also reduces the damage that may be caused to the antenna when replacing the solar film. In addition, the solar film of the present invention is also environmentally friendly and recyclable, further reducing environmental pollution and waste of resources. Finally, the installation of the solar film is completed through the segmentation and self-adhesion steps of the film.

[0037] Embodiment 1: Installation of the front windshield solar film 1.

[0038] First of all, we select materials and choose ultra-thin environmentally friendly films with heat insulation, UV protection and durability as the raw materials for film making to ensure the environmental friendliness and recyclability of the materials.

[0039] The next step is to customize the diaphragm using precision cutting technology based on the specific shape and size of the windshield. The diaphragm is designed to start from the black lace border, bypass the microwave window, and be divided into two in the middle.

[0040] Next, the film is bonded, and the customized film is divided into two parts from the middle and bonded to the two sides of the glass. Due to the hardness and rigidity of the film material, the solar film can automatically and tightly bond to the glass to avoid bubbles.

[0041] The symmetrical division of the film ensures the consistency and aesthetics of the lamination on both sides, and improves the accuracy and efficiency of the film. It also has a self-adhesive effect. The self-adhesive characteristics of the solar film material reduce bubbles and wrinkles during the installation process, ensuring the durability and overall quality of the solar film. Compared with the traditional film lamination method, the traditional film lamination requires on-site cutting and heating to adjust the shape, which is complicated and prone to errors. The solar film of the present invention presets a suitable shape, does not require cutting and baking, simplifies the installation process, and reduces the risk of installation failure.

[0042] Embodiment 2: Installation of the rear windshield solar film 5 .

[0043] The first step is to select materials. We also choose ultra-thin environmentally friendly films with heat insulation, UV protection and durability as raw materials, taking environmental protection and recyclability into consideration.

[0044] Secondly, the diaphragm is customized according to the shape and size of the rear windshield. Considering that the rear windshield has no microwave window and has a rear brake light base and a silver-painted antenna, the diaphragm is designed to go around the black lace and split in two from the middle.

[0045] Next, the film is bonded: the film is split in half from the middle and bonded to the two sides of the glass. The self-bonding properties of the solar film ensure a tight fit and avoid the generation of bubbles.

[0046] Symmetrical design, the symmetrical split design of the rear windshield solar film 5 ensures the consistency and accuracy of the film and improves the efficiency of the film. Protect the antenna, the precise cutting and laminating technology avoids damage to the printed silver wire antenna on the rear windshield, maintaining the signal reception quality in the car.

[0047] Compared with the traditional film method, the traditional film will damage the antenna on the rear windshield during installation, affecting the normal use of electronic equipment in the car. The solar film design of the present invention takes the protection of the antenna into consideration. Through precise cutting and bonding technology, it ensures that the solar film can perfectly fit the glass while avoiding the antenna area.

[0048] The above-mentioned configuration can also be set in other embodiments, and the scope of protection of the present invention includes but is not limited to the situations listed in this embodiment. Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so the scope of protection of the present invention shall be subject to the scope defined by the claims.

[0049] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
