[0002] Vacuum insulation panels are a high-performance insulation material with a thermal conductivity 10-20 times lower than that of conventional insulation cotton. The technical principle is to evacuate the core material (usually glass fiber, fumed silica, etc.) and heat-seal it with aluminum-plastic film. This design eliminates the heat conduction of air inside the core material, thereby greatly improving its thermal insulation performance. The aluminum-plastic film wrapped on the outside protects the internal vacuum and blocks the entry of external gas.

[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0031] The following is combined with Figure 1-4 The present invention is further described in detail.

[0032] Embodiment 1, refer to Figure 1-2 A vacuum panel structure comprises an aluminum-plastic film, a core material 3 and a getter 4; the aluminum-plastic film is provided with two layers, namely an upper aluminum-plastic film layer 1 and a lower aluminum-plastic film layer 2, and the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2 are circumferentially sealed; the core material 3 is filled between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2, the getter 4 is arranged between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2, and the space between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2 is vacuumed; in this way, the core material 3 and the getter 4 are filled between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2, and vacuuming is performed, thereby improving the sound insulation properties of the vacuum panel.

[0033] like Figure 2 As shown, the aluminum-plastic film specifically includes a nylon protective layer 5, a first aluminum foil layer 6 and a polyethylene PE layer 7 which are stacked in sequence. 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 to say, the vacuum panel structure in this embodiment is wrapped by the nylon protective layer 5, which improves the durability of the vacuum panel structure. In addition, the first aluminum foil layer 6 in the aluminum-plastic film can improve the sound insulation of high-frequency sounds in the vacuum panel, reduce the air leakage rate, and improve the durability of the vacuum panel.

[0034] It is further optimized that the getter 4 can be in block or layer form. Figure 1 The getter 4 shown in the figure is in block shape. If the getter is in layer shape, it is spread flat in the vacuum cavity between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2.

[0035] It is further optimized that, in the present embodiment, the thickness of the first aluminum foil layer 6 is 10um to 1000um, and the optimal thickness is 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 to improve the sound insulation of high-frequency sounds in the vacuum panel. At the same time, the thickening of the first aluminum foil layer 6 can further increase the barrier properties of the aluminum-plastic film, reduce the air leakage rate, and improve the durability of the vacuum panel.

[0036] In this embodiment, the thickness of the core material 3 is preferably 3um to 5um, and the core material 3 uses low elastic modulus fiber, specifically one or more of glass fiber, PET fiber, spandex fiber, rubber fiber, polyurethane fiber and silicone rubber fiber.

[0037] Embodiment 2, as Figure 3 As shown, in addition to Example 1, the present application also includes Example 2. Based on Example 1, Example 2 is provided with a rubber damping layer 8 on the side of the lower aluminum-plastic film layer 2 away from the core material 3, and the vacuum panel recorded in Example 1 is compounded 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, the rubber damping layer 8 can protect the vacuum panel from damage by sharp objects on the wall surface, and improve the adaptability of the vacuum panel structure to the adhesion; and a second aluminum foil layer (not shown in the drawing) can also be provided between the rubber damping layer 8 and the lower aluminum-plastic film layer 2 to further improve the sound insulation effect.

[0038] Embodiment three, as Figure 4 As shown, in addition to the above embodiments, the present application also includes embodiment 3. Based on the embodiment 3, a soft material layer or a hard material layer or other functional layer (such as Figure 4 9), in actual production, according to the use requirements, materials of different properties are selected to be arranged on the side of the upper aluminum-plastic film layer 1 away from the core material 3. 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 (car roof, car door, cockpit, flying car cockpit wall, RV bedroom wall, etc.), a soft material layer is generally set, such as genuine leather, imitation leather, imitation suede, rubber, TPE, soft plastic, fabric, memory foam, nylon, modified polypropylene, PVC, ABS, PC, polyester elastomer, non-woven fabric layer or PU foam layer, 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 (inside and outside walls of buildings, inside or outside roofs, building ceilings / floors, etc.). Generally, a hard 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 role in sound absorption during use, further improving the sound insulation performance; for example, if a non-woven fabric layer is added, the vacuum panel structure will have waterproof, tear-resistant and flame-retardant properties, which are not described here one by one.

[0039] Embodiment 4, a method for producing a vacuum panel structure, used for producing the vacuum panel structure described in Embodiment 2, the method comprising:

[0040] Fill the core material 3 and the getter 4 between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2;

[0041] The upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2 are vacuumed and edge-sealed;

[0042] Use alcohol wiping or plasma to clean the surface of the lower aluminum-plastic film layer 2;

[0043] The second aluminum foil layer is back-glued and cut, the rubber damping layer is cut, and then the second aluminum foil layer is firstly laminated on the lower aluminum-plastic film layer 2 and rolled; then the rubber damping layer 8 is laminated on the second aluminum foil layer and rolled; finally, the cost is inspected and the products are packaged and put into storage.

[0044] Embodiment 5, application of vacuum panel structure, the vacuum panel structure is applied to automobiles (car roofs, car doors, cockpits, flying car cockpit walls, RV bedroom walls, etc.), interior and exterior walls of buildings (including the inside or outside of the roof), building ceilings, floors or door panels, etc.

[0045] In summary: by filling the core material 3 and the getter 4 between the upper aluminum-plastic film layer 1 and the lower aluminum-plastic film layer 2 and performing a vacuum treatment, the sound insulation properties of the vacuum panel are improved; and the first aluminum foil layer 6 in the aluminum-plastic film can improve the sound insulation of high-frequency sounds in the vacuum panel, reduce the leakage rate, and improve the durability of the vacuum panel.
