Description

Technical Field

[0001] This utility model relates to the field of bulletproof technology, and in particular to a high-definition heat-insulating bulletproof film. Background Technology

[0002] Existing transparent enclosure structures, such as glass windows and display cases, typically use bulletproof glass to enhance their bulletproof capabilities. Bulletproof glass is composed of multiple layers of glass and an intermediate polymer or PC board. These multi-layered structures absorb and disperse impact forces, thus preventing bullets from penetrating the glass. Bulletproof glass generally has the following three layers: Load-bearing layer: This layer is the first to break upon impact. It typically uses thick, high-strength glass to weaken the bullet's kinetic energy, causing it to lose its ability to continue moving. Transition layer: This layer usually uses organic adhesive materials with strong adhesion and good light resistance. It absorbs some impact energy and changes the bullet's trajectory. Safety protection layer: This layer uses high-strength glass or high-strength transparent organic materials. It has good elasticity and toughness, absorbs most of the impact energy, and ensures that the bullet cannot penetrate this layer.

[0003] The thickness of bulletproof glass is generally proportional to its bulletproof performance. Typically, the thickness of bulletproof glass can range from 18mm to 40mm. Therefore, bulletproof glass is relatively heavy. This places higher demands on the installation conditions of transparent enclosure structures requiring bulletproof functionality, and also increases costs. To address these shortcomings, this invention provides a lightweight, heat-insulating bulletproof film, aiming to solve the problems of thick, heavy, inconvenient, and energy-saving bulletproof glass. It offers the advantages of easy installation and lightweight design. After being applied to ordinary float glass of a certain thickness (12mm), it provides F64 bulletproof protection. Simultaneously, it possesses a certain degree of heat insulation, resulting in some energy savings in everyday use. Utility Model Content

[0004] In order to overcome the shortcomings of existing bulletproof glass, such as large thickness, heavy weight, inconvenient construction, and lack of heat insulation and energy saving effect, the technical problem of this utility model is to provide a lightweight, heat-insulating bulletproof film.

[0005] Technical solution: A high-definition heat-insulating bulletproof film includes a functional layer, a load-bearing layer, a first pressure-sensitive adhesive layer, a safety protection layer, a second pressure-sensitive adhesive layer, a buffer layer, a third pressure-sensitive adhesive layer, and an adhesive layer protective layer. The load-bearing layer is disposed below the functional layer. The safety protection layer is connected to the first pressure-sensitive adhesive layer below the load-bearing layer. The buffer layer is connected to the second pressure-sensitive adhesive layer below the safety protection layer. The third pressure-sensitive adhesive layer is disposed below the buffer layer. The adhesive layer protective layer is disposed below the third pressure-sensitive adhesive layer.

[0006] Furthermore, it is particularly preferred that the functional layer is composed of a wear-resistant layer and an anti-fouling layer, formed by coating with wear-resistant and anti-fouling materials.

[0007] Furthermore, it is particularly preferred that the load-bearing layer is composed of a high-strength polyester film, polycarbonate film, or polyimide film, which is used to buffer the first impact of the bullet and weaken the bullet's kinetic energy.

[0008] Furthermore, it is particularly preferred that the first pressure-sensitive adhesive layer has a certain buffering effect, and at the same time, it is combined with heat insulation material, so that the bulletproof film as a whole has heat insulation function.

[0009] Furthermore, it is particularly preferred that the safety protection layer is made of modified polyurethane elastomer, which enhances the strength and toughness of the polyurethane, giving it a stronger buffering capacity and absorbing most of the impact energy.

[0010] Furthermore, it is particularly preferred that the buffer layer is composed of a high-strength polyester film, polycarbonate film, or polyimide film to further enhance the buffering capacity.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The bulletproof film provided by this invention significantly reduces thickness and weight compared to traditional bulletproof glass, thus achieving a lightweight design. This improvement not only simplifies and speeds up the installation process and reduces replacement costs, but also greatly expands the application range of the bulletproof film. It is particularly suitable for locations where weight is sensitive or installation conditions are limited, such as transparent enclosures of high-rise buildings and vehicles. Furthermore, its F64 bulletproof performance ensures effective protection of personnel and prevents bullet penetration during attacks. Simultaneously, by cleverly integrating heat-insulating materials into the pressure-sensitive adhesive layer, the bulletproof film also achieves excellent heat insulation and energy-saving effects.

[0013] 2. This utility model effectively improves the heat insulation performance of bulletproof membranes by employing a composite heat insulation material bonding buffer layer, providing a sun-protection and energy-saving solution for large enclosure structures. Especially in hot or sunny areas, this design can significantly reduce indoor temperature and decrease energy consumption of air conditioning and other cooling equipment, achieving green energy saving. Simultaneously, the application of modified polyurethane elastomer not only enhances the strength and toughness of the buffer layer but also improves its compatibility with other material layers by reducing tensile strength, solving problems such as delamination and difficulty in construction that often occur with traditional multi-layer composite materials. This innovative material modification technology not only improves the overall performance of bulletproof membranes but also lays a solid foundation for their widespread application in fields such as safety films and bulletproof membranes.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] Example: A high-definition heat-insulating and bulletproof film, such as Figure 1 As shown, the structure includes a functional layer 1, a load-bearing layer 2, a first pressure-sensitive adhesive layer 3, a safety protection layer 4, a second pressure-sensitive adhesive layer 5, a buffer layer 6, a third pressure-sensitive adhesive layer 7, and an adhesive layer protective layer 8. The load-bearing layer 2 is disposed below the functional layer 1. The first pressure-sensitive adhesive layer 3 connects the first load-bearing layer 3 to the safety protection layer 4. The second pressure-sensitive adhesive layer 5 connects the safety protection layer 4 and the buffer layer 6. The third pressure-sensitive adhesive layer 7 is disposed below the buffer layer 6. The pressure-sensitive adhesive layer 7 can be repeatedly positioned, peeled, and reattached for calibration and installation. The adhesive layer protective layer 8 is disposed below the third pressure-sensitive adhesive layer 7. The adhesive layer protective layer 8 serves a dustproof function, protecting the cleanliness of the adhesive layer during construction.

[0018] The functional layer 1 is composed of a wear-resistant layer and an anti-fouling layer, which are coated with wear-resistant and anti-fouling materials to improve the durability and ease of cleaning of the membrane. The wear-resistant material is mainly polyurethane, a high-molecular wear-resistant material, which has excellent wear resistance and chemical corrosion resistance and can maintain stable performance in harsh operating environments. The anti-fouling layer is mainly made of fluorocarbon resin with low surface energy. Due to its unique molecular structure, fluorocarbon resin has extremely low surface energy and excellent anti-fouling performance, which can effectively prevent dust, oil and other pollutants from adhering to the surface of the membrane material.

[0019] The load-bearing layer 2 is composed of a high-strength polyester film, polycarbonate film, or polyimide film, and is used to buffer the first impact of the bullet and weaken the bullet's kinetic energy.

[0020] The first pressure-sensitive adhesive layer 3 has a certain buffering effect, and at the same time, it is combined with heat insulation material, so that the bulletproof film as a whole has heat insulation function.

[0021] The safety protection layer 4 uses modified polyurethane elastomer, which enhances the strength and toughness of the polyurethane, giving it a stronger buffering capacity and absorbing most of the impact energy. The modification makes the tensile capacity of the polyurethane elastomer match that of the load-bearing layer 2 and the buffer layer 6, preventing production and construction difficulties caused by tensile mismatch.

[0022] The buffer layer 6 is composed of a high-strength polyester film, polycarbonate film, or polyimide film, which further enhances the buffering capacity.

[0023] The principle of this embodiment:

[0024] Existing bulletproof films are heavy, inconvenient to install, and lack heat insulation and energy-saving effects. Furthermore, film installation is difficult. This invention addresses this by sequentially compositing functional layer 1, load-bearing layer 2, first pressure-sensitive adhesive layer 3, safety protection layer 4, second pressure-sensitive adhesive layer 5, buffer layer 6, third pressure-sensitive adhesive layer 7, and adhesive layer protective layer 8 from top to bottom. This creates a lightweight, heat-insulating bulletproof film that is easy to install. During installation, the adhesive layer protective layer 8 is peeled off, allowing the film to be installed onto the glass via the third pressure-sensitive adhesive layer 7, ensuring a tight bond between the bulletproof film and the glass. The third pressure-sensitive adhesive layer 7 can be repeatedly peeled and removed during installation, facilitating calibration and installation by workers.

[0025] Functional layer 1, through the combined use of abrasion-resistant and anti-fouling materials, not only possesses excellent abrasion resistance, effectively resisting external scratches and wear, but also exhibits outstanding anti-fouling properties, preventing dust, oil, and other contaminants from adhering to the membrane surface.

[0026] As a core component of the bulletproof membrane structure, the load-bearing layer 2 bears the important task of buffering the initial impact of the bullet and weakening its kinetic energy. The polyester film has high tensile strength and elongation at break, which can quickly disperse energy when the bullet impacts, effectively slowing down the bullet's penetration speed. The polycarbonate film, with its excellent impact resistance and transparency, has high toughness and fracture toughness, which can absorb a large amount of energy when the bullet impacts, thus significantly reducing the threat of the bullet to the subsequent protective layer. The polyimide film has extremely high strength and heat resistance, which can maintain stable performance under extreme high temperature and high pressure environments and withstand the powerful impact of the bullet. By selecting these high-strength polyester film, polycarbonate film, or polyimide film as the materials for the load-bearing layer, we ensure that the bulletproof membrane can quickly disperse and absorb energy when impacted by a bullet, effectively weakening the bullet's kinetic energy, thereby protecting the subsequent protective layer from serious damage.

[0027] Functional layer 1 employs a high-definition optical coating material. Through a special coating treatment with low reflectivity and high transmittance, it effectively reduces light scattering and refraction. The transmittance of this layer material reaches over 95%, ensuring that light maintains a high-definition effect after passing through the film and does not affect visual clarity.

[0028] Functional layer 1 also includes anti-glare treatment, which ensures that it maintains a high-definition transparency under strong light or direct sunlight, and avoids interference from reflected light on the line of sight.

[0029] The wear-resistant and anti-fouling layers of functional layer 1 utilize nano-level transparent coatings, processed through advanced techniques such as vacuum deposition, enabling the film to possess self-cleaning capabilities while maintaining high transparency. This nano-level transparent coating exhibits low refractive index and high optical uniformity, making it suitable for high-definition applications.

[0030] The load-bearing layer 2 uses a high-optical-transparency polyester film, polycarbonate film, or polyimide film material to ensure that it has high strength without affecting light transmittance. The optical transmittance of this layer material reaches over 90%, ensuring a high-definition visual effect and preventing the bulletproof membrane from obstructing the field of vision.

[0031] The load-bearing layer 2 also reduces interlayer optical interference by eliminating internal stress, ensuring uniform overall film thickness and thus avoiding blurring caused by thickness differences.

[0032] The fourth safety layer utilizes a highly transparent modified polyurethane elastomer, which undergoes special optical modulation to reduce dispersion and distortion when light enters the film. This ensures that the safety layer effectively absorbs impact energy without affecting the direct path of light, achieving a high-definition effect. Furthermore, this layer employs nanotechnology to make the polyurethane material molecules more regularly arranged, further improving transparency and impact resistance, ensuring both bulletproof protection and high-definition performance.

[0033] Each pressure-sensitive adhesive layer (such as the first pressure-sensitive adhesive layer 3) is made of optically transparent pressure-sensitive adhesive material. Its thickness and uniformity have been optimized through multiple bonding experiments to achieve seamless bonding between layers without affecting the light propagation path, thereby ensuring the high-definition effect of the overall structure.

[0034] Vacuum bonding technology is used to ensure that there are no air bubbles or tiny particles inside the film layer, so as to avoid visual blurring and loss of high definition caused by tiny impurities.

[0035] The materials of each layer are tested using precise optical simulations, and parameters such as film thickness and material refractive index are adjusted to minimize light refraction, reflection, and scattering in each layer, thereby reducing visual interference and achieving better high-definition effects.

[0036] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
