Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to a honeycomb aluminum composite insulation board and its production process. Background Technology

[0002] Honeycomb aluminum composite insulation board is an innovative building material that integrates energy-saving, heat insulation, and sound insulation functions. It uses honeycomb aluminum as the base material, and this structure gives the material lightweight and high strength. Its composite insulation layer can effectively block heat transfer, and the sound insulation components in the material can significantly reduce external noise interference, creating a quiet and comfortable indoor environment. This board is suitable for various building walls and roofs, and is an ideal choice for achieving building energy conservation and improving the quality of life.

[0003] Chinese patent CN216276242U discloses a honeycomb aluminum composite insulation board, which includes an insulation board body and fixing connectors. The insulation board body includes an anti-corrosion decorative layer, a honeycomb aluminum layer, and an insulation material layer. The anti-corrosion decorative layer is located on the outside of the honeycomb aluminum layer. In this application, the honeycomb aluminum composite insulation board has a honeycomb structure. Compared with aluminum single panels, it has the advantages of light weight per unit area, good stress deformation resistance, excellent bending and flexural strength, and multiple properties of thermal insulation, heat insulation, and sound insulation. Both the material itself and the structural safety of the installation are very high.

[0004] The honeycomb aluminum composite insulation board in the above-mentioned patent has a fixed orientation of the honeycomb aluminum layer, and the load-bearing capacity of the edge position is limited. Collisions and compressions to the edge position can easily cause damage to the edge position of the board, affecting the service life of the honeycomb aluminum composite insulation board. Summary of the Invention

[0005] The purpose of this invention is to provide a honeycomb aluminum composite insulation board and its manufacturing process. The honeycomb aluminum composite insulation board is spliced ​​with a first honeycomb panel facing a fixed direction in the middle position, and four second honeycomb panels are spliced ​​around the first honeycomb panel. The honeycomb cells in the second honeycomb panels are perpendicular to the honeycomb cells in the first honeycomb panels. The edge position is reinforced without increasing the overall thickness of the honeycomb aluminum composite insulation board, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a honeycomb aluminum composite insulation board, comprising a pair of first honeycomb panels, with rock wool board and foam plastic insulation board respectively disposed on both sides between the two first honeycomb panels, a fixing ring disposed around the two first honeycomb panels, the two fixing rings being welded together, a fixing block being welded around the fixing rings, and four first mounting grooves evenly distributed around the fixing blocks, with a second honeycomb panel welded to the middle position inside the four first mounting grooves, the honeycomb orientations of the first and second honeycomb panels being perpendicular to each other. The perpendicular distribution of the first and second honeycomb panels, without increasing the overall thickness of the honeycomb aluminum composite insulation board, reinforces the edge position and forms a vertically interlaced three-dimensional grid structure, which can improve mechanical properties.

[0007] Preferably, a protective plate with a slot connection is provided on one side of the first mounting groove. Polyurethane foam is provided between the protective plate and the second honeycomb panel. After the polyurethane foam is filled, it is covered by the protective plate on the outside. This can wrap the second honeycomb panel inside and fill the gap between the protective plate and the second honeycomb panel with polyurethane foam.

[0008] Preferably, the protective plate is provided with a second mounting post at each of the four corners facing the second honeycomb plate. The extended second mounting post can facilitate the installation of the protective plate, avoid the protective plate being overly embedded in the first mounting groove, and avoid the protective plate being overly squeezed by the polyurethane foam.

[0009] Preferably, reinforcing strips are provided on both sides of the first mounting groove, and the reinforcing strips are welded and fixed to the fixing block. The upper and lower ends of the reinforcing strips are recessed with second mounting grooves, and the second mounting grooves are connected to the second mounting post slots. The reserved second mounting grooves facilitate the insertion of the second mounting post, which helps to improve the stability of the protective plate after installation.

[0010] Preferably, a decorative panel is provided on one side of the exterior of each of the two first honeycomb panels, and epoxy resin is provided between the decorative panel and the first honeycomb panel. A groove is provided inside the decorative panel facing the middle of the honeycomb aluminum composite insulation board. The epoxy resin fills the gaps inside the first honeycomb panel to avoid the formation of a hollow frame structure inside the honeycomb aluminum composite insulation board.

[0011] Preferably, the epoxy resin fills the gaps inside the first honeycomb panel, and after curing, the epoxy resin forms a firm structure with the first honeycomb panel.

[0012] Preferably, the outer wall of the protective plate is provided with a sheet-like protruding reinforcing plate, which is welded and fixed to the edge of the decorative plate. The protruding reinforcing plate facilitates the final welding and fixing of the decorative plate.

[0013] Preferably, the fixing block has mounting holes at all four corners of the side facing the decorative panel, and the decorative panel has a first mounting post facing the mounting hole. The first mounting post is connected to the internal slot of the mounting hole, and the first mounting post is welded and fixed to the decorative panel. The reserved mounting holes facilitate the decorative panel to embed the first mounting post into the mounting hole together during installation.

[0014] A manufacturing process for a honeycomb aluminum composite insulation board includes the following steps: Step 1: Weld fixing rings to the outside of the two first honeycomb panels; Step 2: Place the foam plastic insulation board and rock wool board between the two first honeycomb boards, and then splice the two fixing rings and the first honeycomb boards in sequence to make the rock wool board and the foam plastic insulation board fit together. Weld the edges of the two fixing rings together. Step 3: The fixing block is placed on the outside of a pair of fixing rings, and the edges between the inner wall of the fixing block and the outer wall of the fixing rings are welded together. Step 4: Place the second honeycomb panel in the middle of the first mounting groove inside the fixing block. Spray polyurethane foam on the outside of the first mounting groove. Install and attach the protective plate on the outside of the polyurethane foam. Insert the second mounting post into the second mounting groove and weld the upper and lower ends of the protective plate to the edge of the recessed position of the first mounting groove. Step 5: Epoxy resin is applied to the inside of the first honeycomb panel, and the epoxy resin will fill the gaps inside the entire first honeycomb panel. Step Six: Insert the decorative panel into the mounting hole through the first mounting post at each of the four corners. The edge of the decorative panel should be aligned with the reinforcing plate protruding from the surface of the protective panel. Finally, weld the reinforcing plate and the decorative panel at their contact points.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In the production of the honeycomb aluminum composite insulation board, the middle position of the honeycomb aluminum composite insulation board is mirrored by a first honeycomb panel facing the fixed direction. Four second honeycomb panels are spliced ​​around the first honeycomb panel. The honeycomb cells in the second honeycomb panels are perpendicular to the honeycomb cells in the first honeycomb panels. The edge position is reinforced without increasing the overall thickness of the honeycomb aluminum composite insulation board. When the edge position of the honeycomb aluminum composite insulation board is subjected to collision and compression, the second honeycomb panels and the fixed blocks around the outside can effectively bear the pressure, preventing the surrounding pressure from easily damaging and deforming the first honeycomb panel in the middle position.

[0016] 2. This invention involves covering the edge of the second honeycomb panel with polyurethane foam. The polyurethane foam has adhesive properties, which helps to fix the protective panel. Furthermore, after the polyurethane foam is filled between the protective panel and the second honeycomb panel, it can fill the gap between them, providing excellent waterproof, moisture-proof, and airtight properties. It is worth mentioning that polyurethane foam itself is also an excellent thermal insulation material, which can protect the weaker insulation areas at the edges of the entire honeycomb aluminum composite insulation board, further enabling the entire honeycomb aluminum composite insulation board to become a thermal insulation material for buildings.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, a honeycomb aluminum composite insulation board of this embodiment includes a first honeycomb panel 4, a pair of first honeycomb panels 4 are arranged laterally, and a rock wool board 6 is arranged on one side between the two first honeycomb panels 4. The rock wool board 6 can provide strong fire resistance, and the rock wool board 6 has good high temperature resistance and sound absorption. In addition, the rock wool board 6 has high hardness and high strength, which can further improve the strength of the entire honeycomb aluminum composite insulation board.

[0021] A foam plastic insulation board 12 is provided on the other side between the two first honeycomb panels 4. The foam plastic insulation board 12 can provide excellent thermal insulation capabilities. The foam plastic insulation board 12 has an extremely low thermal conductivity, which can effectively block the thermal bridge that may be formed by a pair of first honeycomb panels 4, greatly improving the overall thermal insulation performance of the board. The foam plastic insulation board 12 is made of foam plastic. Foam plastic has a low density, and its addition has a negligible increase in the overall weight of the board, thus retaining the core advantage of the lightweight honeycomb aluminum panel.

[0022] Furthermore, each of the two first honeycomb panels 4 is surrounded by a fixing ring 5, and the fixing ring 5 is welded and fixed to the first honeycomb panel 4. The fixing ring 5 can provide protection for the first honeycomb panel 4 and facilitate subsequent connection, making it easier to produce honeycomb aluminum composite insulation board.

[0023] In this embodiment, after the fixing ring 5 is welded around the edge of the first honeycomb panel 4, the fixing ring 5 can simultaneously cover one of the rock wool board 6 and the foam plastic insulation board 12. The two fixing rings 5 ​​are welded and fixed together. After the two fixing rings 5 ​​are spliced ​​together, they can cover and wrap the foam plastic insulation board 12 and the rock wool board 6 in the middle position.

[0024] To provide support for the edges of the first honeycomb panel 4 and prevent deformation of the first honeycomb panel 4 due to collisions at the edges, such as... Figure 6 As shown, a fixing block 7 is arranged around the fixing ring 5. The inner wall of the fixing block 7 is welded and fixed to the fixing ring 5. Four first mounting grooves 9 are evenly distributed around the fixing block 7. A second honeycomb plate 10 is arranged in the middle position inside the four first mounting grooves 9. The second honeycomb plate 10 is welded and fixed to the fixing block 7. The second honeycomb plate 10 can support and protect the edge position of the first honeycomb plate 4.

[0025] The first honeycomb plate 4 and the second honeycomb plate 10 are oriented perpendicularly to each other. By oriented perpendicularly to each other, they can adapt to collisions at the edge positions. The first honeycomb plate 4 and the second honeycomb plate 10 can form a vertically intersecting three-dimensional grid structure, which can improve mechanical performance.

[0026] In order to cover and protect the second honeycomb panel 10, a sheet-like protective plate 14 is provided on one side of the outside of the first mounting groove 9, and the protective plate 14 is connected to the first mounting groove 9 by a slot. When splicing the honeycomb aluminum composite insulation board and welding the second honeycomb panel 10 into the first mounting groove 9, the reinforcing piece 17 is inserted into the first mounting groove 9 to cover the second honeycomb panel 10.

[0027] Furthermore, in this application, in order to fill the gap between the second honeycomb panel 10 and the protective panel 14, a polyurethane foam 13 is provided between the protective panel 14 and the second honeycomb panel 10. Before the protective panel 14 is fixed, the polyurethane foam 13 is sprayed onto the surface of the second honeycomb panel 10 so that the gap between the second honeycomb panel 10 and the protective panel 14 can be filled after the protective panel 14 is installed.

[0028] It is worth mentioning that, such as Figure 4 As shown, strip-shaped second mounting posts 15 are provided at the four corners of the side of the protective plate 14 facing the second honeycomb panel 10. In order to further improve the load-bearing capacity of the second honeycomb panel 10, reinforcing strips 11 are provided on both sides of the first mounting groove 9, and the reinforcing strips 11 are welded and fixed to the fixing block 7. The upper and lower ends of the reinforcing strips 11 are recessed with second mounting grooves 18, and the second mounting grooves 18 are connected to the second mounting posts 15 by slots. After the protective plate 14 covers the surface of the second honeycomb panel 10 and the polyurethane foam 13 is squeezed, the second mounting posts 15 will be embedded in the honeycomb position inside the second honeycomb panel 10, which facilitates the production and splicing of the honeycomb aluminum composite insulation board.

[0029] A decorative panel 1 is provided on one side of each of the two first honeycomb panels 4. Epoxy resin 3 is placed between the decorative panel 1 and the first honeycomb panel 4. A groove is provided inside the decorative panel 1 facing the middle of the honeycomb aluminum composite insulation board. The groove facilitates the covering and wrapping of the epoxy resin 3. The epoxy resin 3 fills the gaps inside the first honeycomb panel 4. Filling the gaps inside the first honeycomb panel 4 with epoxy resin 3 can prevent the formation of a hollow frame structure inside the honeycomb aluminum composite insulation board. After the epoxy resin 3 is cured, it is firmly bonded to the first honeycomb panel 4, providing solid lateral support for each fragile honeycomb wall. This greatly enhances the compressive, shear, and deformation resistance of the honeycomb core. When subjected to impact, the stress can be more evenly distributed, avoiding local collapse, making the board more impact-resistant, and improving the load-bearing capacity and bending resistance of the first honeycomb panel 4.

[0030] The filled epoxy resin 3 can effectively block the heat conduction path through the aluminum honeycomb wall, thereby improving the overall thermal insulation performance of the honeycomb aluminum composite insulation board.

[0031] To facilitate the welding of the decorative panel 1, a sheet-like reinforcing plate 17 is provided on the outer wall of the protective plate 14. During welding, the edge of the decorative panel 1 is attached to the side of the reinforcing plate 17. The attachment of the reinforcing plate 17 to the decorative panel 1 facilitates subsequent welding processing. The reinforcing plate 17 is welded and fixed to the edge of the decorative panel 1.

[0032] To prevent decorative panel 1 from loosening after installation, such as Figure 3As shown, the fixing block 7 has mounting holes 8 at the four corners of the side of the decorative panel 1 facing both sides. The side of the decorative panel 1 facing the mounting holes 8 has a first mounting post 2, and the first mounting post 2 is connected to the internal slot of the mounting hole 8. The first mounting post 2 is welded and fixed to the decorative panel 1. After the decorative panel 1 is pressed on both sides of the outside of the honeycomb aluminum composite insulation board, the first mounting post 2 will be embedded into the inside of the mounting hole 8 at the same time.

[0033] Working principle: During the production of honeycomb aluminum composite insulation board, fixing rings 5 ​​are welded to the outside of two first honeycomb panels 4. An area is reserved between the edge of the fixing ring 5 and the edge of the first honeycomb panel 4 for placing a rock wool board 6 and a foam insulation board 12. The rock wool board 6 and the foam insulation board 12 are inserted into the reserved area. The foam insulation board 12 and the rock wool board 6 are placed between the two first honeycomb panels 4. The two fixing rings 5 ​​and the first honeycomb panels 4 are sequentially spliced ​​together, making the rock wool board 6 and the foam insulation board 12 fit together. The edges of the two fixing rings 5 ​​are welded together. A fixing block 7 with a recessed first mounting groove 9 and a protruding reinforcing strip 11 is fitted over the pair of fixing rings 5. The edges between the inner wall of the fixing block 7 and the outer wall of the fixing ring 5 are welded together. The second honeycomb panel 10 is placed in the middle of the first mounting groove 9 inside the fixing block 7. Polyurethane foam 13 is sprayed onto the outside of the first mounting groove 9. The protective plate 14 is externally installed and attached. The second mounting post 15 on the side of the protective plate 14 penetrates the polyurethane foam 13 and is inserted into the interior of the second honeycomb panel 10. At the same time as the second mounting post 15 is inserted, it is inserted into the second mounting groove 18 recessed at the position of the reinforcing strip 11. The upper and lower ends of the protective plate 14 are welded and fixed to the edge of the recessed position of the first mounting groove 9. Epoxy resin 3 is applied inside the first honeycomb panel 4. The epoxy resin 3 will fill the gaps inside the entire first honeycomb panel 4. A decorative plate 1 is installed on the outside of the epoxy resin 3. The decorative plate 1 is inserted into the mounting holes 8 at the four corners of the fixing block 7 through the first mounting post 2 at the four corners. The edge of the decorative plate 1 is attached to the reinforcing piece 17 protruding from the surface of the protective plate 14. Finally, the contact position of the reinforcing piece 17 and the decorative plate 1 is welded to complete the production of the honeycomb aluminum composite insulation board. During the welding process, the epoxy resin 3 is wrapped by the decorative plate 1, which will not cause sparks during welding that could damage the epoxy resin 3.
