[0026] Example 1

[0027] Please see Figure 1-4 The present invention provides the following technical solution:

[0028] A vacuum-insulated exterior wall composite panel, comprising:

[0029] Vacuum interlayer 1;

[0030] The vacuum insulation core includes an aerogel vacuum cylinder 2, a vacuum groove 3, and a vacuum connecting layer 4. Multiple aerogel vacuum cylinders 2 and vacuum grooves 3 are provided. Multiple aerogel vacuum cylinders 2 are opened on the inner wall of the vacuum interlayer 1. Multiple vacuum grooves 3 are opened in multiple aerogel vacuum cylinders 2 respectively. The vacuum connecting layer 4 is opened in the vacuum interlayer 1 and is connected to multiple vacuum grooves 3.

[0031] Fiber-reinforced cement board 9 is disposed on the inner wall of vacuum interlayer 1 and sleeved on the outer surface of multiple aerogel vacuum cylinders 2.

[0032] In a specific embodiment of this utility model, the vacuum interlayer 1, as the core functional area of ​​the entire board, is used to contain and maintain a stable environment for the vacuum insulation structure. Multiple aerogel vacuum cylinders 2 are formed on the inner wall of the vacuum interlayer 1 in a regular arrangement to improve the uniformity of the overall thermal resistance distribution. Each aerogel vacuum cylinder 2 further has a vacuum groove 3 inside, which forms a high-efficiency insulation unit through a vacuuming process. A vacuum connecting layer 4 is also provided inside the vacuum interlayer 1, which is interconnected with all the vacuum grooves 3 to achieve pressure balance between the vacuum grooves 3, thereby ensuring the stability of the overall vacuum environment. Fiber-reinforced cement board 9 is set on the inner wall of vacuum interlayer 1 and sleeved on the outer surface of multiple aerogel vacuum cylinders 2, serving as a fixed support and sealing protection. The fiber-reinforced cement board 9 has good bending and crack resistance, and its internal fiber mesh enhances the overall strength, giving the board high structural stability and durability. By organically combining aerogel vacuum cylinders 2, vacuum grooves 3 and vacuum connecting layer 4, a highly efficient and stable vacuum insulation system is formed, realizing the integrated design of heat preservation, heat insulation, structural load-bearing and decorative functions. It is suitable for various application scenarios such as prefabricated buildings, energy-saving renovations and high-rise buildings.

[0033] Please refer to the details. Figures 1-4 Multiple aerogel vacuum cylinders 2 are made of hydrophobic silica aerogel material and are arranged in a matrix. The outer surface of the aerogel vacuum cylinders 2 is covered with a composite gas barrier film, which is composed of alternating layers of aluminum foil and polyvinyl alcohol film.

[0034] In this embodiment, multiple aerogel vacuum cylinders 2 are all made of hydrophobic silica aerogel material. This material has excellent thermal insulation performance and good hydrophobicity, which can effectively prevent the increase in thermal conductivity due to moisture absorption, thereby ensuring thermal stability during long-term use. All aerogel vacuum cylinders 2 are arranged in a matrix within the vacuum interlayer 1. This arrangement helps to improve the uniformity of thermal resistance distribution and space utilization within the overall board. At the same time, the outer surface of each aerogel vacuum cylinder 2 is covered with a composite gas barrier film, which is composed of alternating layers of aluminum foil and polyvinyl alcohol film. Through the synergistic effect of multiple materials, the gas penetration barrier capability is significantly improved, thereby effectively maintaining the long-term stability of the vacuum state inside the aerogel vacuum cylinder 2. This structural design not only enhances the sealing reliability of the aerogel components, but also improves their aging resistance and mechanical strength, providing a solid guarantee for the entire vacuum insulation system.

[0035] Please refer to the details. Figures 1-4 Both ends of the vacuum interlayer 1 are fixedly connected to a buffer support layer 5, and a support matrix 6 is provided inside the buffer support layer 5. The support matrix 6 is a honeycomb aluminum frame matrix.

[0036] In this embodiment, a support matrix 6 is provided in the buffer support layer 5. The support matrix 6 is a honeycomb aluminum frame matrix structure. This structure has the characteristics of light weight, high strength, good compressive performance and strong buffer energy absorption capacity. It can effectively improve the structural stability and impact resistance of the entire composite integrated panel. When subjected to external force, it can evenly disperse stress, prevent local deformation or damage, thereby extending the service life of the panel and improving installation safety.

[0037] Please refer to the details. Figures 1-4 Multiple filling units 7 are provided on the side of the buffer support layer 5, and the filling units 7 are filled with low-density foam ceramic.

[0038] In this embodiment, the filling unit 7 is filled with low-density foam ceramic material. This material has the advantages of low density, low thermal conductivity, high temperature resistance and low water absorption. While effectively filling and enhancing the overall structural integrity of the board, it also further improves the heat insulation performance, fire resistance and sound absorption and noise reduction capabilities of the board, so that the composite integrated board has more functional advantages on the basis of meeting the mechanical performance requirements.

[0039] Please refer to the details. Figures 1-4 The outer surface of the buffer support layer 5 is provided with a microcrystalline glass panel 8, and the surface of the microcrystalline glass panel 8 is pre-decorated with decorative texture.

[0040] In this embodiment, the surface of the microcrystalline glass panel 8 is pre-fabricated with decorative textures. The microcrystalline glass panel 8 has the characteristics of high strength, corrosion resistance, good weather resistance and high surface smoothness. It can not only effectively improve the appearance of the panel, but also has good anti-fouling and self-cleaning properties, extending the service life of the exterior wall panel. At the same time, its pre-fabricated decorative textures can be customized according to different architectural styles, enhancing the visual expression and decorative effect of the overall building facade.

[0041] Please refer to the details. Figures 1-4 A fiber-reinforced cement board 9 is fixedly connected to the side end of the vacuum interlayer 1. The fiber-reinforced cement board 9 covers the gaps of multiple aerogel vacuum cylinders 2 to form a support body. A fiber mesh is provided inside the fiber-reinforced cement board 9.

[0042] In this embodiment, the fiber-reinforced cement board 9 is wrapped in the gaps between multiple aerogel vacuum cylinders 2 to form an integral support body. The fiber-reinforced cement board 9 has a fiber mesh inside. Through the reinforcement effect of the fiber mesh, the bending resistance, crack resistance and impact resistance of the board are significantly improved, giving it good mechanical strength and structural stability. It can effectively support and protect the internal vacuum insulation structure, ensuring the safety and durability of the entire composite integrated board under complex environmental conditions.

[0043] The working principle and usage process of this utility model are as follows: The vacuum interlayer 1, as the core functional area of ​​the entire panel, is used to contain and maintain a stable environment for the vacuum insulation structure. Multiple aerogel vacuum cylinders 2 are formed on the inner wall of the vacuum interlayer 1 in a regular arrangement to improve the uniformity of the overall thermal resistance distribution. Each aerogel vacuum cylinder 2 further has a vacuum groove 3 inside, which forms a high-efficiency insulation unit through a vacuuming process. A vacuum connecting layer 4 is also provided inside the vacuum interlayer 1, which is interconnected with all the vacuum grooves 3 to achieve pressure balance among the vacuum grooves 3, thereby ensuring the stability of the overall vacuum environment.
