[0026] As Figure 2 The aluminum plastic film specifically comprises a nylon protective layer 5, a first aluminum foil layer 6 and a polyethylene PE layer 7 arranged in sequence, and the polyethylene PE layer 7 in the upper aluminum plastic film layer 1 and the lower aluminum plastic film layer 2 is arranged on the side close to the core material 3, that is, the vacuum plate structure in the embodiment is wrapped by the nylon protective layer 5, which improves the durability of the vacuum plate structure, and the first aluminum foil layer 6 in the aluminum plastic film can improve the sound insulation of high-frequency sound in the vacuum plate, reduce the air leakage rate and improve the durability of the vacuum plate.

[0027] Further optimization is that the getter 4 can be blocky or layered, Figure 1 The getter 4 shown in the figure is blocky, and if the getter is layered, it is laid in the vacuum cavity between the upper aluminum plastic film layer 1 and the lower aluminum plastic film layer 2.

[0028] Further optimization is that, in the embodiment, the thickness of the first aluminum foil layer 6 is 10um to 1000um, and is preferably 50um to 150um, the thickness of the first aluminum foil layer 6 in a general aluminum plastic film is 7um to 10um, the first aluminum foil layer 6 is thickened in design, which is used to improve the sound insulation of high-frequency sound in the vacuum plate, and at the same time, the thickening of the first aluminum foil layer 6 can further increase the barrier property of the aluminum plastic film, reduce the air leakage rate and improve the durability of the vacuum plate.

[0029] In the embodiment, the thickness of the core material 3 is preferably 3um to 5um, and the core material 3 uses low-elasticity modulus fibers, which can be one or more of glass fiber, PET fiber, spandex fiber, rubber fiber, polyurethane fiber and silicone rubber fiber.

Based on Embodiment 1, Embodiment 2 provides a rubber damping layer 8 on the side of the lower aluminum-plastic film layer 2 away from the core material 3. The vacuum plate described in Embodiment 1 is combined with the rubber damping layer 8, so that the material as a whole has the functions of heat insulation, shock absorption and sound insulation at the same time.

Furthermore, a second aluminum foil layer (not shown in the drawings) can be provided between the rubber damping layer 8 and the lower aluminum-plastic film layer 2 to further improve the sound insulation effect.

Figure 4 As shown in reference number 9), in actual production, different materials are selected and placed on the side of the upper aluminum-plastic film layer 1 away from the core material 3 according to usage requirements. When the side of the upper aluminum-plastic film layer 1 away from the core material 3 is the side that is easily touched by the human body (such as car roofs, car doors, cockpits, cockpit walls of flying cars, bedroom walls of RVs, etc.), a soft material layer is generally set, such as genuine leather, imitation leather, imitation suede, rubber, TPE, soft plastics, fabrics, memory foam, nylon, modified polypropylene, PVC, ABS, PC, polyester elastomers, non-woven fabric layers, or PU foam layers, etc.; if The side of the upper aluminum-plastic film layer 1 away from the core material 3 needs to have certain protective functions such as wear resistance and hardness (for building interior and exterior walls, roof interior or exterior, building ceilings / floors, etc.). Generally, a rigid material layer is set, such as wood grain, metal decorative panels, ABS, rubber, structural panels, etc.; specific materials can also be selected according to different functions. For example, if a PU foam layer is added, it will play a sound absorption role during use, further improving the sound insulation performance; if a non-woven fabric layer is added, the vacuum panel structure will have waterproof, tear-resistant and flame-retardant properties, etc., which will not be elaborated here.
