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 waterproofing 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 enters 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, ultimately deteriorating its thermal insulation performance. Summary of the Invention

[0005] To address the above problems, 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 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 MCM panel, and a waterproof layer. 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 MCM panel is disposed on the outer surface of the vacuum insulation panel. The waterproof layer is disposed between the vacuum insulation panel and the MCM panel.

[0007] Alternatively, the waterproof layer may be a waterproof cloth, waterproof membrane, or waterproof sheet covering one side of the vacuum insulation panel.

[0008] Optionally, the waterproof layer is a waterproof adhesive layer applied to one side of the vacuum insulation panel and covering the surface.

[0009] Optionally, the vacuum insulation and decorative integrated panel also includes a sealing portion that surrounds the periphery of the vacuum insulation panel.

[0010] 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.

[0011] Optionally, the adsorbent assembly also includes a gas adsorbent.

[0012] Alternatively, the MCM plate is an MCM plate composed of rock powder or ceramic powder aggregates.

[0013] Optionally, the vacuum insulation and decorative integrated panel also includes a reinforcing plate disposed between the MCM panel and the vacuum insulation panel.

[0014] By placing a waterproof layer between the MCM board and the vacuum insulation panel, moisture can be prevented 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 would accelerate the entry of water vapor from the outer skin into the vacuum interior, leading to a deterioration of its thermal insulation performance. Therefore, even when using the MCM board as a decorative panel, the thermal insulation performance of the vacuum insulation panel will not decrease or will not decrease significantly, effectively extending or guaranteeing the service life of the vacuum insulation panel.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] 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 MCM panel 2, and a waterproof layer 3. 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-absorbing 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 MCM panel 2 is disposed on the outer surface of the vacuum insulation panel 1. The waterproof layer 3 is disposed between the vacuum insulation panel 1 and the MCM panel 2.

[0020] 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.

[0021] 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. Furthermore, a material that combines fibers and powder can also be used as the core material 11. 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. When powder is used in the core material 11, it is preferable to place the powder in a breathable bag for use.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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 compromising its vacuum level and 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.

[0026] For building walls or equipment surfaces requiring decorative effects while meeting the requirements of modern green and energy-saving building decoration materials, in this embodiment, an MCM board 2 is provided on the outer surface of the vacuum insulation board 1. MCM board 2, short for Modified Inorganic Powder Composite Building Facing Sheet, is mainly made of modified inorganic powder, commonly known as soft porcelain. The main raw materials of the MCM board 2 series include ordinary urban construction waste soil (including loess, red soil, white soil, and black soil), cement waste, porcelain slag, and stone powder, etc., and the MCM board 2 series products have various colors and textures depending on the color and material of the raw materials. In practical use, the 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 the MCM board 2. In the vacuum insulation and decorative integrated panel 100 of this utility model, the MCM board 2 is a rock powder and ceramic powder agglomerated board. In other embodiments, the 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 placing the MCM board 2 on the outer surface of the vacuum insulation board 1, the vacuum insulation and decorative integrated panel 100 not only has good thermal insulation performance for the outer surface of walls or machinery and equipment, but also achieves a good decorative effect in actual use.

[0027] Because the MCM board 2 has high thermal conductivity, a thermal bridging effect may occur when it is used in combination with the vacuum insulation board 1. Compared with the prior art of setting two MCM boards 2 on the sides of the vacuum insulation board 1, in this embodiment, the MCM board 2 is only set on one side of the vacuum insulation board 1, which can significantly reduce the thermal bridging effect.

[0028] Meanwhile, the characteristics of the raw materials and manufacturing process of the MCM board 2 result in the presence of tiny pores in its internal structure. Therefore, during the use of the vacuum insulation and decorative integrated panel 100 with the MCM board 2 on its outer surface, moisture from the external environment can penetrate through the pores of the MCM board 2 and contact the outer packaging material 13, and then enter the vacuum portion of the vacuum insulation panel 1 through the outer packaging material 13. Although the vacuum insulation panel 1 contains a moisture absorbent 121, as the usage time of the vacuum insulation and decorative integrated panel 100 increases, moisture from the pores of the MCM board 2 continues to penetrate into the vacuum portion of the vacuum insulation panel 1, ultimately leading to a significant increase in the thermal conductivity of the vacuum insulation panel 1 and affecting its insulation performance.

[0029] Therefore, in this embodiment, a waterproof layer 3 is provided between the vacuum insulation panel 1 and the MCM panel 2. This waterproof layer 3, through physical barrier means, can prevent external moisture from invading the vacuum portion of the vacuum insulation panel 1 through the pores in the MCM panel 2. The waterproof layer 3 can be a waterproof cloth, waterproof membrane, or waterproof sheet (e.g., PVC sheet) covering one side surface of the vacuum insulation panel 1; in other embodiments of this utility model, the waterproof layer 3 is a waterproof adhesive layer (e.g., silane polymer adhesive) applied to one side surface of the vacuum insulation panel 1 and covering the entire surface.

[0030] In this embodiment, reference Figure 1 A protective plate 5 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 5 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 5 is not limited to the materials listed above and can also be other types of materials; no specific limitations are made here.

[0031] In this embodiment, reference Figure 1A sealing part 4 is provided around the perimeter of the vacuum insulation panel 1. The sealing part 4 is made of waterproof material, and the specific material type is not limited. The upper and lower edges of the sealing part 4 are in contact with the waterproof layer 3 and the protective plate 5, respectively, so that the outer surface of the outer casing 13 of the vacuum insulation panel 1 is completely covered by the waterproof layer 3, the sealing part 4, and the protective plate 5. The sealing part 4 is mainly used to seal the perimeter of the vacuum insulation panel 1 to protect it. Through the combined covering of the waterproof layer 3, the sealing part 4, and the protective plate 5, water or other harmful substances can be prevented from penetrating into the interior of the vacuum insulation panel 100 through the outer casing 13 during use. At the same time, during the transportation and installation of the vacuum insulation panel 100, the sealing part 4 and the protective plate 5 can also provide physical protection for the vacuum insulation panel 1, preventing damage to the outer casing 13 of the vacuum insulation panel 1 and affecting its thermal insulation performance, thus effectively extending the service life of the vacuum insulation panel 100.

[0032] In some other implementations, refer to Figure 2 A reinforcing plate 6 is also provided between the MCM board 2 and the vacuum insulation board 1. It can be used to improve the overall strength of the vacuum insulation and decorative integrated board 100, and can also be combined with a waterproof layer 3 to prevent moisture or other harmful substances from penetrating the vacuum insulation board 1. Figure 2 The illustration shows a case where the reinforcing plate 6 is disposed above the waterproof layer 3. In other embodiments, the reinforcing plate 6 may also be disposed below the waterproof layer 3. The reinforcing plate 6 may be made of aluminum or cement board. In other embodiments, other types of materials may also be used for the reinforcing plate 6, which are not specifically limited here.

[0033] 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.
