Description

Technical Field

[0001] This utility model relates to the field of thermal insulation materials technology, specifically a vacuum insulation and decorative integrated panel. Background Technology

[0002] In the design of some household appliances, machinery, and building exterior panels, thermal insulation is often a key consideration. Heat transfer primarily occurs through three pathways: convection, conduction, and radiation. In a vacuum environment, convection heat transfer ceases to occur, and by using materials with low contact thermal conductivity as the core material, insulation materials with extremely low thermal conductivity can be formed. Current technology utilizes an air-barrier outer layer covering a core material with fine pores, such as glass wool or silica powder, and then depressurizes and seals the interior of the outer layer, thus forming a vacuum insulation panel (VIP). Based on the vacuum principle, the vacuum environment inside the core material of the VIP achieves extremely low thermal conductivity and excellent insulation performance. Furthermore, VIP is environmentally friendly and energy-efficient, making it an advanced, green, and highly efficient thermal insulation material.

[0003] In some machinery and building exterior wall panels, in addition to requiring thermal insulation properties, the external materials also need to have a certain decorative effect. For ease of installation, some panels use vacuum insulation panels as the main body and are covered with decorative panels, thus combining insulation and decoration functions—a vacuum insulation and decoration integrated panel. However, because vacuum insulation panels have poor strength and waterproof performance, they cannot be directly used with MCM (Modified Clay Materials) panels used as decorative panels.

[0004] Specifically, MCM panels are mostly made from inorganic materials such as ordinary urban construction waste soil, cement scraps, ceramic slag, and stone powder. Furthermore, the unique manufacturing process results in a porous internal structure. When MCM panels are used in conjunction with vacuum insulation panels as exterior building or equipment materials, moisture from the environment can directly contact the vacuum insulation panel through the pores of the MCM, causing the outer layer of the vacuum insulation panel to peel off or creating a high-humidity environment. This accelerates the entry of water vapor from the outer layer into the vacuum interior, leading to a deterioration in its thermal insulation performance. Additionally, current MCM panels often use aggregates of rock and ceramic powders; when combined with vacuum insulation panels, the overall structural strength may not be guaranteed. Summary of the Invention

[0005] To address the above issues, this utility model provides a vacuum insulation and decorative integrated panel that can be reasonably combined with vacuum insulation panels and MCM panels, so that the thermal insulation performance and strength of the vacuum insulation panel will not be degraded or will be reduced due to the use of MCM panels, thus extending the service life of the vacuum insulation panel.

[0006] This utility model provides a vacuum insulation and decorative integrated panel, including a vacuum insulation panel, an integrally formed metal plate, and an MCM panel. The vacuum insulation panel includes a core material, an adsorbent assembly, and an outer covering. The adsorbent assembly is disposed on the surface or inside the core material and includes at least a moisture adsorbent capable of adsorbing water. The outer covering covers the outer periphery of the core material and the adsorbent assembly. The metal plate can wrap around the outer surface and sides of the vacuum insulation panel. The MCM panel is disposed on the side of the metal plate away from the vacuum insulation panel.

[0007] Optionally, the vacuum insulation and decorative integrated panel also includes a protective panel disposed on the side of the vacuum insulation panel away from the MCM panel.

[0008] Optionally, the adsorbent assembly also includes a gas adsorbent.

[0009] Alternatively, the MCM plate is an MCM plate composed of rock powder or ceramic powder aggregates.

[0010] Optionally, the metal plate may be an aluminum plate or an aluminum alloy plate.

[0011] Optionally, one or more fasteners may be provided around the perimeter of the metal plate.

[0012] <Beneficial Effects>

[0013] By embedding an integrally molded metal plate between the MCM board and the vacuum insulation panel, this metal plate can wrap the outer surface and sides of the vacuum insulation panel. This prevents moisture from directly contacting the vacuum insulation panel through the pores of the MCM, thus preventing the outer skin of the vacuum insulation panel from peeling off or being exposed to a high-humidity environment. This, in turn, accelerates the entry of water vapor from the outer skin into the vacuum interior, leading to a deterioration of its thermal insulation performance. The metal plate also has good structural strength, compensating for the insufficient strength of the MCM board in the integrated vacuum insulation and decorative panel, and providing physical protection for the vacuum insulation panel. This avoids the risk of the vacuum insulation panel rupturing due to collisions with other objects during transportation or installation, thereby ensuring that the vacuum insulation panel and the MCM board can be used together effectively.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0017] This embodiment provides a vacuum-insulated decorative integrated panel 100. Figure 1 This is a cross-sectional schematic diagram of the vacuum insulation and decorative integrated panel 100 provided in this embodiment, as shown below. Figure 1 As shown, the vacuum insulation and decorative integrated panel 100 includes a vacuum insulation panel 1, an integrally formed metal panel 4, and an MCM panel 2. The vacuum insulation panel 1 includes a core material 11, an adsorbent assembly 12, and an outer covering 13. The adsorbent assembly 12 is disposed on the surface or inside the core material 11, and the adsorbent assembly 12 includes at least a water adsorbent 121 capable of adsorbing water. The outer covering 13 covers the outer periphery of the core material 11 and the adsorbent assembly 12. The metal panel 4 can wrap around the outer surface of the vacuum insulation panel 1. Figure 1 (top surface) and sides ( Figure 1 The diagram shows the wrapping of the left and right sides of the vacuum insulation panel 1 (in reality, all four sides are wrapped); the MCM panel 2 is placed on the side of the metal plate 4 away from the vacuum insulation panel 1.

[0018] Vacuum insulation panels 1 are generally composed of a porous dielectric core material 11, a high-performance composite airtight outer casing material 13 that maintains its vacuum level, and an adsorbent assembly 12, all assembled using vacuum encapsulation technology. The vacuum interior of the core material 11 effectively prevents heat transfer caused by air convection, thus significantly reducing its thermal conductivity. It possesses environmentally friendly and energy-efficient characteristics, making it an advanced, green, and highly efficient thermal insulation material.

[0019] In this embodiment, the type of core material 11 is not specifically specified. It is a porous body with an air-layer ratio of approximately 90%, and conventionally known core materials 11 such as glass fiber, polyurethane, and silica powder can be used. Furthermore, in other embodiments, other materials can be used to prepare the core material 11, such as: continuous air bubbles such as urethane foam, styrene foam, and phenolic foam; inorganic fibers such as glass wool, asbestos, alumina fiber, and aluminosilicate fiber; organic fibers such as polyester fiber; and powders such as pearlite. Additionally, a material that combines fibers and powder can also be used as the core material 11. Furthermore, when fibers are used in the core material 11, it is preferable to align the fibers approximately perpendicular to the thickness direction of the vacuum insulation board 1 or the core material 11, and it is preferable not to use adhesives or the like to bond the fibers together, so that the intersections between the fibers are less likely to become thermal bridges. Furthermore, when powder is used in the core material 11, it is preferable to place the powder in a breathable bag for use.

[0020] In this embodiment, the adsorbent assembly 12 is disposed on the surface or inside the core material 11, and is generally manufactured by depressurizing and sealing the various adsorbents contained in the adsorbent assembly 12 together with the core material 11 inside the vacuum insulation plate 1. Figure 1 The illustration shows an adsorbent assembly 12 disposed inside the core material 11. In other embodiments, the adsorbent assembly 12 may also be disposed on the surface of the core material 11.

[0021] In this embodiment, the adsorbent assembly 12 includes a moisture adsorbent 121 and a gas adsorbent 122. The moisture adsorbent 121 can adsorb moisture in the internal space of the vacuum insulation panel 1. Specifically, the moisture adsorbent 121 can use calcium oxide and magnesium chloride as raw materials. The gas adsorbent 122 can adsorb nitrogen in the internal space of the vacuum insulation panel 1, and can also adsorb oxygen, hydrogen, or other gases that may affect the vacuum level inside the vacuum insulation panel 1. In this embodiment, the gas adsorbent 122 can use zeolite and barium-lithium alloy as raw materials. The gas adsorbent 122 can complement the moisture adsorbent 121, improving the adsorbent assembly 12's ability to comprehensively absorb moisture and different types of gases. In other embodiments of this invention, the moisture adsorbent 121 and gas adsorbent 122 are not limited to the materials listed above, and can also be other types of materials, which are not specifically limited here.

[0022] As the encapsulation material of the vacuum insulation panel 1 and an essential condition for maintaining vacuum, the outer packaging material 13 plays a very important role in the vacuum insulation panel 1. The outer packaging material 13 usually needs to have certain strength, ductility, puncture resistance, and excellent water and gas barrier properties.

[0023] In this embodiment, reference Figure 1The outer packaging material 13 covers the outer periphery of the core material 11 and the adsorbent assembly 12. The outer packaging material 13 primarily functions to enclose and isolate the core material 11 and the adsorbent assembly 12, preventing penetration. Firstly, it encloses the core material 11 and the adsorbent assembly 12 to isolate them from outside air, maintaining a vacuum state inside the outer packaging material 13 through pressure reduction and sealing. Secondly, the outer packaging material 13 itself is a dense material, effectively preventing nitrogen, oxygen, and water vapor from penetrating into the vacuum insulation panel 1 and thus damaging its vacuum level and reducing its thermal insulation performance. In this embodiment, the outer packaging material 13 is a metal layer or a laminate with a barrier layer such as a metal or ceramic vapor deposit. In other embodiments, the outer packaging material 13 is not limited to the materials listed above and can be other types of materials, which are not specifically limited here.

[0024] For some building walls or equipment surfaces that require decorative effects while meeting the requirements of modern green and energy-saving building decoration materials, MCM board 2 can be installed on the outer surface of vacuum insulation board 1. MCM board 2, short for modified inorganic powder composite building veneer sheet, is mainly made of modified inorganic powder, commonly known as soft porcelain. The main raw materials of MCM board 2 series products include ordinary urban construction waste soil (including loess, red soil, white soil, and black soil), cement waste blocks, porcelain slag, and stone powder, etc. Depending on the color and material of the raw materials, MCM board 2 series products have a variety of colors and textures. In practical use, MCM board 2 can be customized according to specific decorative requirements, including the specific pattern on the MCM board 2 panel and the materials used to prepare MCM board 2. In the vacuum insulation and decoration integrated panel 100 of this embodiment, MCM board 2 is a rock powder and ceramic powder agglomerated board. In other embodiments, MCM board 2 is not limited to the materials listed above and can also be other types of materials, which are not specifically limited here. As a safe and environmentally friendly decorative panel, by combining MCM board 2 with vacuum insulation board 1, the vacuum insulation and decorative integrated panel 100 can not only have good thermal insulation performance for the outer surface of walls or machinery and equipment, but also achieve good decorative effect in actual use.

[0025] In this embodiment, an integrally formed metal plate 4 is provided between the vacuum insulation panel 1 and the MCM panel 2. This metal plate 4 can cover the outer surface and sides of the vacuum insulation panel 1. Its integral structure prevents external moisture from invading the vacuum portion of the vacuum insulation panel 1 through the pores in the MCM panel 2 and the sides of the vacuum insulation panel 1. The metal plate 4 can be made of aluminum or aluminum alloy. Due to the high metal strength of these materials, the metal plate 4 can be used as the metal frame of the vacuum insulation and decorative integrated panel 100, addressing the relatively low structural strength of the MCM panel 2. This provides higher structural strength to the vacuum insulation and decorative integrated panel 100 and provides physical protection for the vacuum insulation panel 1 during transportation and installation, preventing the outer cladding material 13 from being accidentally damaged or deformed due to collisions with other objects, thus avoiding a reduction in the thermal insulation performance of the vacuum insulation panel 1. The aluminum or aluminum alloy plate surface easily forms an oxide layer, giving it good corrosion resistance and allowing for long-term use in water-containing environments. Meanwhile, the low metal density of aluminum plates or aluminum alloy plates makes the installation process of the vacuum insulation and decorative integrated panel 100 easier. The metal plate 4 of this utility model is not limited to the materials listed above, and can also be other types of materials, which are not specifically limited here.

[0026] In this embodiment, reference Figure 1 A protective plate 3 is provided on the side of the vacuum insulation panel 1 away from the MCM panel 2, which can be made of calcium silicate board. This protective plate 3 improves the puncture resistance of the outer cladding material 13, preventing damage to the outer cladding material 13 from collisions with other objects during transportation or installation of the integrated vacuum insulation and decorative panel 100, thus extending the service life of both the outer cladding material 13 and the vacuum insulation panel 1. The protective plate 3 is not limited to the materials listed above and can also be other types of materials; no specific limitations are made here.

[0027] In this embodiment, reference Figure 1 One or more fasteners 5 are provided around the periphery of the metal plate 4. Rivets can be used as fasteners 5 to thread the vacuum insulation decorative integrated panel 100 to the wall or equipment surface, or other connection methods can be used; this invention does not limit this. Compared to the embodiment of using adhesives to bond the vacuum insulation decorative integrated panel 100 to the wall or equipment surface, the embodiment of this invention, which uses fasteners 5 to fix the vacuum insulation decorative integrated panel 100 to the wall or equipment surface, has a more secure connection. The specific number of fasteners 5 can be determined according to the specific usage environment and fixing requirements, and is not limited here.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
