[0049] As Figures 1 - 7 shown, the present invention provides an enhanced thermal insulation decorative board, including:

[0050] A metal plate 1, the metal plate 1 has a front side and a back side. The vacuum insulation panel 3 is pasted on the back side of the metal plate 1 through the self-leveling mortar layer 2, and the lightweight inorganic plaster layer 4 is arranged around the vacuum insulation panel 3.

[0051] In this embodiment, the metal plate 1 serves as the outer layer. Its relatively strong material and good weather resistance not only endow the decorative board with a bright and lasting appearance, but also can effectively resist various physical impacts from the outside. With its self-leveling property, the self-leveling mortar layer 2 can evenly and tightly fill the tiny gaps between the metal plate 1 and the vacuum insulation panel 3, achieving seamless bonding, thus minimizing the thermal bridge effect and improving the heat insulation effect to the greatest extent. The vacuum insulation panel 3, with its excellent low thermal conductivity, becomes the core of the entire heat insulation system and can achieve efficient heat insulation at a very small thickness. The lightweight inorganic plaster layer 4 surrounds the vacuum insulation panel 3. It not only forms an all-round protection for the vacuum insulation panel 3, but also, due to its lightweight characteristics, reduces the weight of the overall structure, facilitates construction and installation, and reduces the requirements for the firmness of installation. In addition, the lightweight inorganic plaster layer 4 also has good fire resistance, further enhancing the safety of the heat insulation decorative board. The arrangement of the self-leveling mortar layer 2, the lightweight inorganic plaster layer 4 and the lightweight inorganic plaster layer 4 on the back of the metal plate 1 improves the ability of the metal plate 1 to prevent deformation, makes the metal plate 1 flatter, and enhances the aesthetic effect.

[0052] Furthermore, it further includes a permeable crystalline mortar layer 5. The permeable crystalline mortar layer 5 is arranged on the side of the vacuum insulation panel 3 away from the self-leveling mortar layer 2. The self-leveling mortar layer 2, the lightweight inorganic plaster layer 4 and the permeable crystalline mortar layer 5 completely cover the surface of the vacuum insulation panel 3.

[0053] In this embodiment, the addition of the permeable crystalline mortar layer 5 brings multi-faceted performance improvements to the heat insulation decorative board. It can deeply penetrate into the tiny pores and cracks on the surface of the vacuum insulation panel 3 and generate insoluble crystalline substances through chemical reactions, thereby blocking the pores and cracks and forming a dense waterproof layer, effectively preventing the intrusion of moisture. Even when exposed to a humid environment for a long time or frequently washed by rain, it can ensure the dryness of the vacuum insulation panel 3 and maintain its excellent heat insulation performance. At the same time, the permeable crystalline mortar layer 5 has excellent self-healing ability. When fine cracks appear on the surface, it can react again under the condition of water to repair the cracks, further enhancing the waterproof performance. In addition, its good compatibility and adhesion with the vacuum insulation panel 3 ensure that there will be no problems such as delamination and peeling during long-term use, greatly extending the service life of the heat insulation decorative board. In addition, the self-leveling mortar layer 2, the lightweight inorganic plaster layer 4 and the permeable crystalline mortar layer 5 achieve all-round wrapping protection for the vacuum insulation panel 3, improving the service life.

[0054] Furthermore, it further includes a fiberglass mesh 6. The fiberglass mesh 6 is provided in both the self-leveling mortar layer 2 and the lightweight inorganic plaster layer 4.

[0055] In this embodiment, the incorporation of the mesh fabric 6 has a profound impact on the performance of the self-leveling mortar layer 2 and the lightweight inorganic plaster layer 4. The mesh fabric 6 is woven from high-strength fiber materials. When subjected to tensile force, the mesh fabric 6 can bear most of the stress and disperse it over a larger area, thus significantly improving the tensile strength of the self-leveling mortar layer 2 and the lightweight inorganic plaster layer 4. This means that under conditions such as thermal expansion and contraction caused by temperature changes, the self-leveling mortar layer 2 and the lightweight inorganic plaster layer 4 are not prone to cracking. At the same time, the mesh fabric 6 can also effectively inhibit the expansion of cracks. Even if there are tiny cracks in the self-leveling mortar layer 2 and the lightweight inorganic plaster layer 4, the mesh fabric can prevent the cracks from further extending and avoid the formation of through cracks, thereby maintaining the structural integrity and thermal insulation performance of the thermal insulation decorative board.

[0056] Furthermore, the mesh fabric 6 is of an integrated structure. A part of the mesh fabric 6 is located within the self-leveling mortar layer 2, and the other part is located within the lightweight inorganic plaster layer 4.

[0057] In this embodiment, the integrated structure of the mesh fabric 6 provides a strong guarantee for the coordinated work between the self-leveling mortar layer 2 and the lightweight inorganic plaster layer 4. Due to the continuity of the mesh fabric 6, when subjected to external forces, the stress can be smoothly transmitted between the two layers, avoiding local damage caused by stress concentration. This synergistic effect enables the two layers of materials to jointly bear various complex loads, improving the stability and reliability of the entire structure. In addition, the integrated design reduces the splicing and connection links during construction, reduces the construction difficulty and human error, and improves the construction quality and efficiency.

[0058] Furthermore, the metal plate 1 is polygonal and also includes side plates 11. The side plates 11 are provided at each side of the metal plate 1 close to the edge of the metal plate 1.

[0059] In this embodiment, designing the metal plate 1 as polygonal and setting the side plates 11 at its edges is an optimization and innovation of the structure of the thermal insulation decorative board. The polygonal design can better adapt to the diverse geometric shapes and facade design requirements of buildings, enabling the thermal insulation decorative board to fit the wall surface more closely during installation, reducing the gaps and unevenness at the corners, and improving the overall aesthetics. The presence of the side plates 11 greatly enhances the strength and rigidity of the edge of the metal plate 1, effectively preventing deformation and damage at the edge during transportation, installation, and use. Especially when subjected to lateral pressure or impact, the side plates 11 can provide additional support and protection to maintain the shape and structural stability of the decorative board.

[0060] Furthermore, there are bending notches at the intersections of adjacent sides of the metal plate 1, and the side plates 11 are formed by bending the part close to the edge of the metal plate 1.

[0061] In this embodiment, by setting a bending notch at the intersection of two adjacent sides of the metal plate 1 and forming the side plate 11 by bending the part close to the edge of the metal plate, this unique design brings multiple benefits. First, the design of the bending notch makes the bending process of the side plate 11 smoother, reducing the concentration of internal stress of the material, thereby improving the forming quality and strength of the side plate 11. Second, using the material of the metal plate 1 itself to form the side plate not only saves raw materials, reduces production costs, but also avoids additional welding or connection processes, reducing potential connection defects and quality hazards. Moreover, the side plate 11 formed by bending has natural continuity and consistency with the metal plate 1, with a tight combination, no gaps and connection weaknesses, and can better withstand external forces from all directions, improving the integrity and stability of the entire structure.

[0062] Furthermore, it further includes a first fixing plate 7. The first fixing plate 7 is arranged around the metal plate 1 and is used to connect with the wall.

[0063] In this embodiment, the setting of the first fixing plate 7 establishes a reliable connection bridge between the thermal insulation decorative board and the wall. Through the first fixing plates 7 evenly distributed around the metal plate 1, the connection force between the decorative board and the wall is evenly distributed, avoiding connection failure caused by excessive local stress. In addition, the first fixing plate 7 is usually made of corrosion-resistant stainless steel material and undergoes surface treatment, having good durability and being able to maintain stable connection performance during long-term use. Moreover, through the first fixing plate 7, during the construction of the building, it can be directly cast and connected to the exterior wall, and during post-installation, it can also be anchored to the exterior wall through the fixing holes 71.

[0064] Furthermore, fixing holes 71 are formed on the first fixing plate 7.

[0065] A connection structure includes a thermal insulation decorative board. The metal plate 1 is polygonal. Side plates 11 are arranged at each side close to the metal plate 1. First strip-shaped holes 12 are formed on the side plates 11. The connection structure includes a connecting plate 81. One end of the connecting plate 81 is provided with a first plate 82 and a second plate 83. The first plate 82 and the second plate 83 are arranged back to back. The first plate 82 is used to be inserted into the first strip-shaped hole 12 of one thermal insulation decorative board, and the second plate 83 is used to be inserted into the first strip-shaped hole 12 of another adjacent thermal insulation decorative board. A second fixing plate 84 is used to be arranged on the wall, and the connecting plate 81 is movably connected with the second fixing plate 84

[0066] In this embodiment, the cooperation between the first strip-shaped hole 12 on the side plate 11 and the connecting plate 81 realizes flexible connection in the horizontal direction. The first plate 82 and the second plate 83 are respectively inserted into the first strip-shaped holes 12 of adjacent thermal insulation decorative boards, which can not only limit the relative displacement of adjacent boards in the horizontal direction, but also allow fine adjustment within a certain range to adapt to the dimensional errors and wall surface unevenness during the installation process. This connection method enables multiple thermal insulation decorative boards to form a continuous and flat decorative surface, greatly improving the overall aesthetics of the exterior wall.

[0067] Furthermore, a second strip-shaped hole 85 is formed on the connecting plate 81, a connecting screw hole 86 is provided on the second fixing plate 84, and a connecting screw 87 is further included. The connecting screw 87 is arranged in the second strip-shaped hole 85, and one end thereof is threadedly connected to the connecting screw hole 86. The connecting screw 87 is used to connect the connecting plate 81 and the second fixing plate 84.

[0068] In this embodiment, the movable connection method of the second strip-shaped hole 85 on the connecting plate 81 and the connecting screw hole 86 on the second fixing plate 84 through the connecting screw 87 provides great flexibility and adjustability for the installation of the thermal insulation decorative board. The length of the second strip-shaped hole 85 allows the connecting plate to move and adjust the angle within a certain range, so as to better adapt to the unevenness of the wall surface and installation errors. The threaded connection between the connecting screw 87 and the connecting screw hole 86 provides a reliable fastening force to ensure that the connecting plate 81 can be firmly fixed on the second fixing plate 84 after the adjustment. This movable connection method not only facilitates the on-site installation and adjustment by construction workers, but also can absorb the deformation and vibration of the wall to a certain extent, reduce the influence on the thermal insulation decorative board, and improve the durability and stability of the connection structure.
