[0002] With the improvement of people's living standards and the continuous improvement of the quality of the home environment, the appearance and service life of furniture have become the focus of consumers' attention. In order to maintain the beauty of the furniture surface, a layer of decorative film is usually attached to the surface of the furniture to provide an additional layer of protection for the furniture to prevent scratches, wear, collisions and other damages caused by daily use.

[0003] In the existing technology, traditional furniture decorative films generally only have anti-scratch and wear-resistant protection functions, and cannot effectively isolate ultraviolet rays. When furniture is exposed to sunlight, the ultraviolet rays in the sunlight will cause the surface of the furniture to fade, yellow or age, especially wooden or leather furniture, thereby affecting the service life of the furniture; at the same time, when furniture is exposed to direct sunlight, thermal radiation will cause the surface temperature of the furniture to rise, especially when the sunlight is strong in summer, the heat will gradually erode the coating on the surface of the furniture, causing the furniture coating to peel, crack or lose its luster, thereby affecting the durability and appearance of the furniture.

[0004] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0012] According to the above technical solution, in the anti-ultraviolet composite film, the anti-scratch layer is an acrylic resin coating, and the thickness of the acrylic resin coating is 4-50 μm.

[0013] According to the above technical solution, in the anti-ultraviolet composite film, the thickness of the PET substrate layer is 30-140 μm, and the thickness of the BOPA film layer is 20-50 μm.

[0014] According to the above technical solution, in the anti-ultraviolet composite film, the bonding layer is a polyurethane adhesive layer, and the thickness of the polyurethane adhesive layer is 5-25 μm.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides an anti-ultraviolet composite film, including a PET substrate layer 10, an anti-scratch layer 20, an anti-ultraviolet layer 30, a heat insulation layer 40, a BOPA film layer 50, an adhesive layer 60 and a release film layer 70;

[0028] The PET substrate layer 10 is positioned above the BOPA film layer 50 and is bonded to the BOPA film layer 50 via an adhesive. The PET substrate layer 10 has excellent mechanical strength, tensile strength, and tear resistance, providing overall structural support and durability for the composite film. Its smooth and uniform surface makes it suitable as a substrate for other functional coatings. The BOPA film layer 50 exhibits high impact resistance and toughness, effectively preventing breakage or fracture of the composite film when subjected to external forces or pressure, thereby enhancing its durability. Furthermore, the BOPA film layer 50 exhibits excellent barrier properties, effectively preventing external moisture from entering the furniture surface and causing erosion. In this embodiment, the PET substrate layer 10 is 30 μm thick, and the BOPA film layer 50 is 20 μm thick.

[0029] The thermal insulation layer 40 is coated on the surface of the PET substrate layer 10, the anti-ultraviolet layer 30 is coated on the surface of the thermal insulation layer 40, and the anti-scratch layer 20 is coated on the surface of the anti-ultraviolet layer 30; the anti-scratch layer 20 can enhance the wear resistance and scratch resistance of the composite film, prevent the furniture from being scratched and damaged by external friction and collision during daily use, and maintain the aesthetics of the furniture; the anti-ultraviolet layer 30 can absorb and reflect ultraviolet rays, prevent ultraviolet rays from penetrating the composite film and affecting the surface material of the furniture, and avoid fading, yellowing or aging of the furniture due to ultraviolet radiation; the provision of the thermal insulation layer 40 can reduce heat conduction through the composite film, especially infrared heat radiation in sunlight. The thermal insulation layer 40 can reflect or absorb part of the heat to reduce the temperature increase on the surface of the furniture due to sunlight, and avoid heat affecting the service life of the surface coating of the furniture.

[0030] The adhesive layer 60 is coated on the bottom surface of the BOPA film layer 50, and the release film layer 70 is provided on the adhesive surface of the adhesive layer 60. The release film layer 70 is used to provide isolation protection for the adhesive layer 60. The composite film can be attached to the surface of the furniture through the adhesive layer 60. The provision of the release film layer 70 can keep the adhesive performance of the adhesive layer 60 stable when not in use, so that the adhesive effect of the composite film is not affected during long-term storage and transportation, thereby avoiding failure of the adhesive layer 60 and ensuring the bonding strength and effect of the composite film.

[0031] The anti-ultraviolet layer 30 is a titanium dioxide coating having a thickness of 40 nm. The titanium dioxide coating has excellent ultraviolet absorption and scattering capabilities and can provide good shielding effects on the 320-400 nm and 280-320 nm bands of ultraviolet rays. Setting the thickness of the titanium dioxide coating to 40 nm can provide sufficient ultraviolet blocking capability without affecting transparency, thereby effectively protecting the furniture surface from ultraviolet damage.

[0032] Furthermore, the heat-insulating layer 40 is a tungsten oxide coating having a thickness of 60 nm. The tungsten oxide coating can absorb or reflect infrared rays in sunlight, thereby reducing the accumulation of infrared heat on the surface of the furniture and protecting the furniture materials from damage by high temperatures.

[0033] Furthermore, the anti-scratch layer 20 is an acrylic resin coating having a thickness of 4 μm. The acrylic resin coating has excellent hardness and wear resistance, which can prevent the furniture from being scratched and scratched during daily use, thereby improving the aesthetics and user experience of the furniture.

[0034] Furthermore, the adhesive layer 60 is a polyurethane adhesive layer having a thickness of 5 μm. Polyurethane adhesive not only has excellent bonding properties but also has excellent flexibility, ensuring that the composite film can adapt to curved or irregular shapes of furniture surfaces without cracking or peeling.

[0035] Furthermore, the release film layer 70 is a polyethylene film. Polyethylene film has a low surface energy. When the composite film needs to be bonded to furniture, the polyethylene film can be easily peeled off without damaging the adhesive layer 60, ensuring that the adhesive layer 60 is in optimal bonding performance during use.

[0036] Furthermore, the non-adhesive surface of the release film layer 70 is coated with an antistatic coating. Static electricity buildup can cause dust, impurities, and fine particles to adsorb on the surface of the release film layer 70. Applying an antistatic coating to the non-adhesive surface effectively reduces surface resistance and static electricity generation, thereby preventing dust and particles from adhering to the film surface and maintaining the cleanliness of the composite film.

[0043] Furthermore, the heat-insulating layer 40 is a tungsten oxide coating having a thickness of 240 nm. The tungsten oxide coating can absorb or reflect infrared rays in sunlight, thereby reducing the accumulation of infrared heat on the surface of the furniture and protecting the furniture materials from damage by high temperatures.
