Description

Technical Field

[0001] This utility model belongs to the field of composite panels, and in particular relates to a sandwich structure composite insulation panel. Background Technology

[0002] Building fires are one of the major disasters threatening human life and property. With the popularization of super high-rise buildings and new energy facilities (such as lithium battery energy storage stations), fire risk management faces greater challenges. The insulation boards used in buildings need to have both thermal insulation and excellent fire resistance. Currently, common building insulation boards mainly include organic insulation boards (such as polystyrene boards and polyurethane boards) and inorganic insulation boards (such as rock wool boards and glass wool boards). These boards are usually connected by simple adhesives between layers. Over a long period of use, they are prone to interface delamination, failure of thermal insulation and fire resistance functions under the action of temperature changes, rain corrosion or strong winds. Moreover, the fire-resistant structure inside commonly used composite boards is usually a continuous whole. When a fire occurs in a certain place, there is a lack of effective barrier structure inside, which can easily cause the fire to spread rapidly and make it difficult to effectively achieve the effect of fire compartment isolation. In addition, the gaps at the splicing positions of composite boards can easily become smoke and fire channels, forming thermal bridges, further reducing the overall fire resistance performance. Utility Model Content

[0003] The purpose of this utility model is to provide a sandwich structure composite insulation board to solve the problems of commonly used composite boards, which are usually connected by simple adhesives between layers. Over long-term use, these boards are prone to delamination, failure of insulation and fire resistance due to temperature changes, rain corrosion or strong winds. Furthermore, the fire-resistant structure inside commonly used composite boards is usually a continuous whole. When a fire occurs in a certain area, the lack of an effective barrier structure inside makes it easy for the fire to spread rapidly and it is difficult to effectively achieve the effect of fire compartment isolation. In addition, the gaps at the joints of composite boards can easily become smoke and fire channels, forming thermal bridges and further reducing the overall fire resistance performance.

[0004] To achieve the above objectives, the specific technical solution of this utility model for a sandwich structure composite insulation board is as follows:

[0005] A sandwich-structured composite insulation board includes a core layer; surface layers are provided on both sides of the core layer; and a panel layer is provided on the outer side of the core layer and the surface layers; the core layer is composed of silica aerogel composite material; the surface layer is composed of inorganic glass fiber layer; the panel layer is composed of composite silicate cement; a support mesh is embedded inside the core layer, the support mesh having a honeycomb structure; multiple intersecting partition strips are provided between the two sides of the core layer and the surface layers, the multiple partition strips forming a grid; the partition strips extend from the surface of the core layer and are embedded inside the surface layer.

[0006] Furthermore, the thickness of the support mesh is the same as that of the core material layer; the support mesh is made of rigid or semi-rigid inorganic refractory material.

[0007] Furthermore, the partition strip is made of fiber-reinforced cement board strip.

[0008] Furthermore, the panel layer has protruding edges on its adjacent sides, and the protruding edges of the two panel layers on the same insulation board are arranged at an angle to each other.

[0009] Furthermore, when the two insulation boards are spliced ​​together, the protruding edge of one insulation board overlaps the protruding edge of the other insulation board.

[0010] Furthermore, the panel layer has mounting holes at the protruding edge; fixing bolts are installed in the mounting holes.

[0011] Furthermore, the panel layer is provided with a soft rubber sealing strip on the side of the raised edge; the panel layer is provided with a sealing groove on the side opposite the raised edge where the soft rubber sealing strip is located.

[0012] This utility model discloses a sandwich-structure composite insulation board with the following advantages: The symmetrical sandwich structure comprising a core layer, a surface layer, and a panel layer, along with a support mesh of equal height embedded in the core layer, provides a supporting framework for the core layer, preventing compression deformation or localized collapse during long-term use. Furthermore, the rigid or semi-rigid inorganic refractory material used to make the core layer divides it into multiple independent units, ensuring that the core layer and support mesh do not melt or burn at high temperatures and maintain their shape. The partition strips increase the bonding strength between the core layer and the surface layer, preventing delamination and detachment of the composite board during prolonged use. In addition, multiple partition strips form a grid-like grille, which is extremely effective in preventing the spread of flames and high temperatures inside the composite board during a fire, increasing the fire safety of the composite board. By setting the raised edge of the panel layer, when multiple insulation boards are laid, the staggered overlap effect formed by the raised edge is achieved, and then the adjacent insulation boards are connected and fixed to the building surface by fixing bolts, forming a strong mechanical fixing effect. This greatly increases the connection strength between the building and the composite board. Moreover, the overlapping insulation boards have a better thermal bridging and smoke and fire blocking effect compared to the common straight through gaps, improving the overall thermal insulation, airtightness and fire resistance of the wall.

[0020] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a sandwich structure composite insulation board according to this utility model.

[0021] like Figure 1-6 As shown, this utility model discloses a sandwich structure composite insulation board, comprising a core layer 1; surface layers 2 are provided on both sides of the core layer 1; a panel layer 3 is provided on the outer side of the core layer 1 and the surface layer 2; the core layer 1 is composed of silica aerogel composite material; the surface layer 2 is composed of inorganic glass fiber layer; the panel layer 3 is composed of composite silicate cement; a support mesh 4 is embedded inside the core layer 1, the support mesh 4 having a honeycomb structure; multiple intersecting partition strips 5 are provided between the two sides of the core layer 1 and the surface layer 2, the multiple partition strips 5 forming a grid; the partition strips 5 extend from the surface of the core layer 1 and are embedded inside the surface layer 2.

[0022] Combination Figure 1-6 As shown, a symmetrical sandwich structure is constructed by combining a core layer 1 made of silica aerogel composite material, a surface layer 2 made of inorganic glass fiber, and a panel layer 3 made of composite silicate cement. The core layer 1 made of silica aerogel composite material serves as the core thermal insulation foundation of this composite panel. By utilizing the characteristics of silica aerogel composite material, such as low thermal conductivity, non-flammability at high temperatures, and non-release of toxic gases, the safety of the building and the effect of thermal insulation and energy saving are improved from the material perspective.

[0023] like Figure 3As shown, the thickness of the support mesh 4 is the same as that of the core material layer 1. The support mesh 4 is made of rigid or semi-rigid inorganic refractory material. The core material layer 1 is embedded with the support mesh 4 of the same height. The support mesh 4 provides a support skeleton for the core material layer 1, preventing the core material layer 1 from being compressed or partially collapsed during long-term use. At the same time, due to its rigid or semi-rigid inorganic refractory material characteristics, the core material layer 1 is divided into multiple independent units, ensuring that the core material layer 1 and the support mesh 4 do not melt or burn at high temperatures and can maintain their shape.

[0024] like Figure 3 As shown, multiple intersecting partition strips 5 are provided between the core material layer 1 and the surface layer 2 on both sides. The partition strips 5 are made of fiber-reinforced cement board strips. The partition strips 5 increase the bonding force between the core material layer 1 and the surface layer 2, preventing the composite board from delaminating and falling off during long-term use. At the same time, the multiple partition strips 5 form a grid, and the fire resistance of the fiber-reinforced cement board strips 5 is used to effectively block the spread of flames and high temperatures inside the composite board in the event of a fire, thereby increasing the fire safety of the composite board.

[0025] like Figure 4-5 As shown, the panel layer 3 has protruding edges 6 on both sides. The protruding edges 6 of the two panel layers 3 on the same insulation board are set at an angle to each other. When the two insulation boards are spliced, the protruding edge 6 of one insulation board overlaps the protruding edge 6 of the other insulation board. The panel layer 3 has mounting holes 7 at the protruding edge 6. Fixing bolts 8 are installed in the mounting holes 7. Through the setting of the protruding edge 6 of the panel layer 3, when multiple insulation boards are laid, the staggered overlap effect formed by the protruding edge 6 is achieved. Then, the adjacent insulation boards are connected and fixed to the building surface by fixing bolts 8, forming a strong mechanical fixing effect. This greatly increases the connection strength between the building and the composite board. Moreover, the overlapping insulation boards have a better thermal bridge and smoke and fire channel blocking effect compared with the common straight through gaps, improving the overall thermal insulation, airtightness and fire resistance of the wall.

[0026] like Figure 4-5 As shown, a soft rubber sealing strip 9 is provided on the side of the raised edge 6 of the panel layer 3; a sealing groove 10 is provided on the side of the panel layer 3 opposite to the soft rubber sealing strip 9. During the laying and fixing of this composite panel, when the next composite panel overlaps the previous composite panel, the soft rubber sealing strip 9 is inserted into the corresponding sealing groove 10. Then, the mechanical connection strength is increased by fixing bolts 8, forming a combination sealing connection of upper and lower double layers of soft rubber sealing strip 9 and sealing groove 10 between the two connected composite panels. This constitutes two elastic sealing systems between the two composite panels, which can automatically and effectively seal the gaps between the composite panels, isolate air convection and moisture penetration, greatly improve the airtightness and thermal insulation of the building envelope, and can also effectively block the generation of smoke and fire channels when a fire occurs, preventing the fire from spreading violently.
