[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 To be continued Figure 4 A prefabricated house insulation integrated wall panel includes a decorative layer 1, a first adhesive layer 2, an insulation layer 3, a second adhesive layer 4, and a structural layer 5 arranged sequentially. The decorative layer 1 is connected to the insulation layer 3 through the first adhesive layer 2, and the insulation layer 3 is connected to the structural layer 5 through the second adhesive layer 4. A plurality of vacuum insulation cavities 31 are uniformly distributed in the insulation layer 3, and the vacuum insulation cavities 31 are filled with nano-aerogel insulation material 32.

[0024] The decorative layer 1 is a fiber cement board with a pattern layer resembling stone or wood grain on its surface. Both the first adhesive layer 2 and the second adhesive layer 4 are polyurethane adhesive layers. The vacuum insulation cavity 31 is arranged in a honeycomb pattern. The structural layer 5 is a reinforced concrete layer with a crisscrossing steel mesh 51 within it. A dovetail groove 52 is provided on the side of the structural layer 5 away from the second adhesive layer 4. The dovetail groove 52 is arranged along the length of the structural layer 5, and a connecting strip 6 is provided in the dovetail groove 52 adjacent to the integrated wall panel. The connecting strip 6 is made of aluminum alloy, has a dovetail-shaped cross-section, and is interference-fitted with the dovetail groove 52.

[0025] The working principle of this utility model of an integrated thermal insulation wall panel for prefabricated houses is as follows: The corresponding functions are achieved through the material properties of each layer. The decorative layer 1 serves as the exterior display part, providing fire resistance, moisture resistance, and decorative effect thanks to the properties of fiber cement board. The first adhesive layer 2 uses the adhesive properties of polyurethane adhesive to firmly connect the decorative layer 1 to the insulation layer 3. The insulation layer 3 relies on the uniformly distributed honeycomb-shaped vacuum insulation cavity 31 and the nano-aerogel insulation material 32 filled within the cavity to reduce heat conduction and achieve efficient insulation. The second adhesive layer 4 then tightly bonds the insulation layer 3 to the structural layer 5. The structural layer 5 provides mechanical support through reinforced concrete and the internal crisscrossing steel mesh 51, ensuring the strength of the wall panel. During installation, adjacent wall panels are quickly spliced ​​together through a dovetail groove 52 set along the length of one side of the structural layer 5 and an aluminum alloy connecting strip 6 with a dovetail-shaped cross-section and an interference fit.

[0026] The functions of each layer of the integrated thermal insulation wall panel for prefabricated houses according to this utility model are as follows:

[0027] Decorative layer 1: Made of fiber cement board, it has fireproof and moisture-proof properties. Its surface is decorated with a pattern layer that imitates stone or wood grain, which serves a decorative and aesthetic purpose and meets the appearance requirements of different architectural styles.

[0028] First adhesive layer 2: Composed of a polyurethane adhesive layer, utilizing the excellent bonding properties of polyurethane adhesive to tightly bond the decorative layer 1 and the insulation layer 3 together, ensuring a stable connection between the two layers and avoiding delamination.

[0029] Insulation layer 3: The interior contains uniformly distributed, honeycomb-shaped vacuum insulation cavities 31, filled with nano-aerogel insulation material 32. The vacuum environment effectively prevents air convection heat loss, and the nano-aerogel insulation material 32 has extremely low thermal conductivity. The combination of the two greatly reduces heat transfer, achieving efficient thermal insulation and meeting building energy conservation standards.

[0030] The second adhesive layer 4 is also a polyurethane adhesive layer, which is used to firmly bond the insulation layer 3 to the structural layer 5, ensuring the integrity and stability of the entire wall panel structure.

[0031] Structural layer 5: This is a reinforced concrete layer with a crisscrossing steel mesh 51 inside. Reinforced concrete has high compressive and flexural strength, and the steel mesh 51 further enhances its structural strength, providing mechanical support for the entire wall panel, enabling it to withstand various loads and ensuring the structural safety of the prefabricated house.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
