Technical Field
[0001] This utility model relates to the field of vacuum insulation board technology, and in particular to a composite vacuum insulation board. Background Technology
[0002] With economic development and social progress, the construction industry has grown rapidly, and living environments have improved dramatically. Consequently, the demands on building materials have become increasingly stringent. To enhance energy efficiency, vacuum insulation panels have gradually gained attention. Vacuum insulation panels are a new type of high-efficiency insulation material based on the principle of vacuum insulation. They combine the advantages of vacuum insulation, microporous insulation, and multi-layer insulation, thus exhibiting outstanding insulation performance.
[0003] Existing composite vacuum insulation panels typically consist of a vacuum insulation panel and a connecting plate. The connecting plate is positioned on one side of the vacuum insulation panel, allowing the composite vacuum insulation panel to be installed on an exterior wall, thereby achieving exterior wall insulation. However, the connection between the vacuum insulation panel and the connecting plate in existing technologies is sometimes not secure enough, thus affecting the usability of the composite vacuum insulation panel. Utility Model Content
[0004] Based on the above-mentioned problems existing in the prior art, the purpose of this application embodiment is to provide a composite vacuum insulation board, wherein the vacuum insulation board includes a bottom shell, and the connection area between the bottom shell and the connecting plate is large, thereby making the connection between the connecting plate and the vacuum insulation board more secure.
[0005] The technical solution adopted by this application to solve its technical problem is: a composite vacuum insulation board, including a vacuum insulation board and a connecting plate;
[0006] The vacuum insulation panel includes a bottom shell, a core material, and a barrier film. The bottom shell includes a lower connecting part, a ring connecting part, and an edge sealing part. The lower connecting part is connected to the lower part of the ring connecting part, and the upper part of the ring connecting part is connected to the edge sealing part. A receiving groove is formed inside the bottom shell, and the core material is disposed in the receiving groove. The barrier film is heat-sealed together with the edge sealing part.
[0007] The connecting plate includes an integrally formed bottom layer and a ring layer. The bottom layer is fixedly connected to the lower connecting part, the inner side of the ring layer is fixedly connected to the ring connecting part, and the top of the ring layer is fixedly connected to the sealing part.
[0008] Furthermore, the barrier film consists of, from the inside out, a heat-sealing layer, an aluminum foil layer, a nylon layer, a PET layer, and a glass fiber layer.
[0009] Furthermore, the vacuum insulation panel also includes an adsorbent, which is disposed on the core material.
[0010] Furthermore, the outer side of the annular layer is recessed to form a positioning groove.
[0011] Furthermore, the positioning groove includes a first positioning groove and a second positioning groove, the first positioning groove being located on one side of the annular layer and the second positioning groove being located on the other side of the annular layer; it also includes a positioning block, one end of which is disposed in the first positioning groove and the other end of which is disposed in the second positioning groove.
[0012] Furthermore, the core material is ultrafine glass wool, centrifugal cotton, or chopped glass fiber.
[0013] Furthermore, the connecting plate is a PU board, XPS board, or EPS board.
[0014] Furthermore, the bottom shell is a stainless steel bottom shell.
[0015] The beneficial effects of this application are as follows: Since the bottom shell includes a lower connecting part, a ring connecting part, and an edge sealing part, after the connecting plate is connected to the vacuum insulation panel, the bottom layer is fixedly connected to the lower connecting part, the inner side of the ring layer is fixedly connected to the ring connecting part, and the top of the ring layer is fixedly connected to the edge sealing part. This results in a large connection area between the connecting plate and the vacuum insulation panel, making the connection between them more secure. Simultaneously, since the vacuum insulation panel includes a bottom shell, a core material, and a barrier membrane, and is a shell-type four-sided sealed vacuum insulation panel, this type of vacuum insulation panel does not require edge folding, and corners are less prone to leakage. After this type of vacuum insulation panel is connected to the connecting plate, the connecting plate and the edge sealing part are fixed together, thus making the composite vacuum insulation panel neat and easy to fix on the exterior wall.

Detailed Implementation
[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] like Figures 1 to 5 As shown, the present invention discloses a composite vacuum insulation board, comprising a vacuum insulation board 1 and a connecting plate 2. The vacuum insulation board 1 comprises a bottom shell 11, a core material 12, and a barrier film 13. The bottom shell 11 comprises a lower connecting part 111, a ring connecting part 112, and an edge sealing part 113. The lower connecting part 111 is connected to the lower part of the ring connecting part 112, and the upper part of the ring connecting part 112 is connected to the edge sealing part 113. A receiving groove 114 is formed inside the bottom shell 11, and the core material 12 is disposed in the receiving groove 114. The barrier film 13 is heat-sealed together with the edge sealing part 113. The connecting plate 2 comprises an integrally formed bottom layer 21 and a ring layer 22. The bottom layer 21 is fixedly connected to the lower connecting part 111, the inner side of the ring layer 22 is fixedly connected to the ring connecting part 112, and the top of the ring layer 22 is fixedly connected to the edge sealing part 113.
[0025] Thus, the composite vacuum insulation board of this utility model has a bottom shell 11 including a lower connecting part 111, a ring connecting part 112 and an edge sealing part 113. After the connecting plate 2 is connected to the vacuum insulation board 1, the bottom layer 21 is fixedly connected to the lower connecting part 111, the inner side of the ring layer 22 is fixedly connected to the ring connecting part 112, and the top of the ring layer 22 is fixedly connected to the edge sealing part 113. This results in a large connection area between the connecting plate 2 and the vacuum insulation board 1, making the connection between the connecting plate 2 and the vacuum insulation board 1 more secure.
[0026] Meanwhile, since the vacuum insulation panel 1 includes a bottom shell 11, a core material 12 and a barrier film 13, the vacuum insulation panel 1 is a shell-type four-sided sealed vacuum insulation panel 1. This type of vacuum insulation panel 1 does not require folding edges, and the corner positions are not prone to leakage. After this type of vacuum insulation panel 1 is connected with the connecting plate 2, the connecting plate 2 is fixed together with the sealing part 113, so that the composite vacuum insulation panel is neat and easy to fix on the exterior wall.
[0027] Optionally, the barrier film 13 consists of, from the inside out, a heat-sealing layer 131, an aluminum foil layer 132, a nylon layer 133, a PET layer 134, and a fiberglass layer 135. The fiberglass layer 135 is essentially fiberglass cloth placed within the PET layer 134. On one hand, the fiberglass cloth enhances the overall mechanical properties of the vacuum insulation panel 1. Since the vacuum insulation panel 1 is relatively fragile, the fiberglass cloth acts like a layer of "armor," improving its tensile and bending resistance, making it less prone to damage during installation and use. On the other hand, the fiberglass cloth provides protection. It prevents external moisture, dust, and other substances from entering the vacuum insulation panel 1, avoiding these factors from affecting its insulation performance. Once moisture enters, it may disrupt the vacuum environment inside the vacuum insulation panel 1, reducing the insulation effect.
[0028] Furthermore, the vacuum insulation panel 1 also includes an adsorbent 14, which is disposed on the core material 12. By providing the adsorbent 14, after the vacuum insulation panel 1 is formed by vacuum heat sealing, the adsorbent 14 adsorbs the residual moisture in the core material 12, resulting in good heat preservation effect of the vacuum insulation panel 1.
[0029] In a preferred embodiment of this invention, a positioning groove 221 is formed by recessing the outer side of the annular layer 22. Specifically, the positioning groove 221 includes a first positioning groove 2211 and a second positioning groove 2212. The first positioning groove 2211 is located on one side of the annular layer 22, and the second positioning groove 2212 is located on the other side of the annular layer 22. It also includes a positioning block 3, with one end of the positioning block 3 disposed in the first positioning groove 2211 and the other end of the positioning block 3 disposed in the second positioning groove 2212.
[0030] By setting positioning grooves 221 and positioning blocks 3, after multiple composite vacuum insulation boards are fixed to the wall, adjacent composite vacuum insulation boards are connected together, thus firmly fixing the composite vacuum insulation boards to the wall. Specifically, the first positioning groove 2211 can be a left groove, the second positioning groove 2212 can be a right groove, and / or the first positioning groove 2211 can be an upper groove, and the second positioning groove 2212 can be a lower groove. The positioning grooves 221 and positioning blocks 3 cooperate to connect together, achieving a firm connection between multiple composite vacuum insulation boards.
[0031] Furthermore, the bottom shell 11 can be a stainless steel bottom shell 11. The bottom shell 11 can be formed by a stamping process or by a vacuum forming process.
[0032] In this embodiment, the core material 12 is ultrafine glass wool, centrifugal wool, or short chopped glass fiber, and the connecting plate 2 is a PU board, XPS board, or EPS board. The connecting plate 2 can be directly foamed and molded on the vacuum insulation board 1.
[0033] The connecting plate 2 is directly foamed and molded onto the vacuum insulation board 1. This process allows the connecting plate 2 to be tightly bonded to the vacuum insulation board 1, reducing the thermal bridging effect, improving the overall thermal insulation performance and structural stability, while also increasing production efficiency and reducing production costs.
[0034] The vacuum insulation board 1 of this type of composite vacuum insulation board, when combined with materials such as EPS and XPS, has the following advantages:
[0035] 1. Significantly improved thermal insulation performance. Vacuum insulation board 1 itself has an extremely low thermal conductivity. When combined with EPS and XPS, it can further reduce the overall thermal conductivity of the material. Under the same thickness, it can greatly improve the thermal insulation effect and reduce heat transfer.
[0036] 2. Compensating for each other's shortcomings. EPS and XPS materials may experience aging and deformation during long-term use, while vacuum insulation board 1 has better stability. The composite can improve the overall stability and durability of the material. At the same time, vacuum insulation board 1 is relatively brittle, while EPS and XPS have certain flexibility and cushioning properties. The composite can combine the advantages of both to a certain extent, improving the impact resistance.
[0037] 3. Enhanced waterproof and moisture-proof performance. XPS boards themselves have good moisture resistance, but EPS boards have a relatively high water absorption rate. Vacuum insulation boards usually have good barrier properties. When combined with EPS and XPS, they can compensate for the shortcomings of EPS to a certain extent, improve the overall waterproof and moisture-proof performance of the material, and enable it to maintain good thermal insulation effect in humid environments.
[0038] 4. Optimized construction performance. EPS and XPS boards are lightweight and easy to cut and install, while vacuum insulation board 1 may require special treatment during construction. The composite material combines the construction advantages of both, making the material easier to operate, improving construction efficiency, and reducing construction difficulty and cost.
[0039] The main application areas of this type of composite vacuum insulation board are:
[0040] 1. Building Insulation: In building exterior wall insulation systems, composite materials can reduce the thickness of the insulation layer while ensuring insulation performance, increasing the usable area of the building. They also improve the fire resistance and durability of the exterior walls, making them suitable for building insulation in various climates, especially in cold regions where they effectively reduce winter heating energy consumption. In roof insulation, they can prevent heat from entering the room from the roof in summer, reducing indoor air conditioning energy consumption, and also prevent indoor heat loss through the roof in winter.
[0041] 2. Cold chain logistics. Used for insulation and heat preservation of cold chain equipment such as refrigerated trucks, insulated boxes, and cold storage, it can better maintain a low-temperature environment, reduce cold loss, lower energy consumption, extend the distance and time of cold chain transportation, and ensure the quality and safety of goods during transportation and storage. Furthermore, the composite material can be customized to meet the specific needs of different cold chain equipment, improving insulation performance and equipment usability.
[0042] 3. Home Appliance Sector. In household refrigerators, freezers, and other refrigeration equipment, composite materials can improve the insulation performance of the equipment, allowing for thinner walls and increased internal effective volume, while reducing energy consumption, thus meeting consumer demand for large-capacity, energy-efficient appliances. In addition, in some high-end home appliances, such as wine cabinets and cigar cabinets, where high requirements are placed on insulation performance and appearance, composite materials can also provide better solutions.
[0043] 4. Aerospace Industry. In the thermal insulation systems of aerospace vehicles, high-performance insulation materials are required to protect the internal equipment and personnel from extreme temperatures. Vacuum insulation panels, when combined with materials such as EPS and XPS, can be customized to meet specific needs and the aerospace industry's requirements for lightweight, high-efficiency insulation, and high-temperature resistance.
[0044] The composite vacuum insulation board of this invention has application value in the fields of building insulation, cold chain logistics, home appliances and aerospace. The appropriate core material, connecting plate material and molding process can be selected according to the specific usage requirements and environmental conditions.
