Description

Technical Field

[0001] This utility model relates to the technical field of exterior wall insulation materials, specifically to a fire-resistant and flame-retardant exterior wall insulation material. Background Technology

[0002] Exterior wall insulation materials are decorative materials installed on the exterior walls of buildings to provide thermal insulation. Currently, exterior wall insulation materials are usually single-material insulation materials, such as extruded polystyrene (XPS) boards sprayed with stone-like paint and then cut into blocks, or foamed cement boards sprayed with stone-like paint and then cut into blocks. While XPS board insulation materials offer good thermal insulation, their fire resistance is poor; similarly, foamed cement insulation materials, while offering good fire resistance, suffer from poor thermal insulation. Therefore, there is an urgent need to design a fire-resistant and flame-retardant exterior wall insulation material to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a fire-resistant and flame-retardant exterior wall insulation material to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fire-resistant and flame-retardant exterior wall insulation material includes an outer shell, a decorative layer on one side of the outer wall of the outer shell, an extruded polystyrene board and a foamed cement board inside the outer shell, the foamed cement board being located on the side of the extruded polystyrene board away from the decorative layer, the outer wall of the foamed cement board away from the extruded polystyrene board having a corrugated pattern, and a fire-resistant and permeable layer being provided on the outer wall of the extruded polystyrene board.

[0005] Furthermore, an adhesive layer one is provided between the extruded polystyrene board and one side inner wall of the outer shell, and an adhesive layer two is provided between the extruded polystyrene board and the foamed cement board.

[0006] Furthermore, the top outer wall of the housing is integrally formed with a mounting plate, the side wall of the mounting plate has evenly distributed mounting holes, and the bottom outer wall of the housing is provided with a clearance groove that matches the mounting plate.

[0007] Furthermore, the top outer wall of the housing is provided with a plug-in groove, and the bottom outer wall of the housing is provided with a plug-in plate.

[0008] Furthermore, the top outer wall of the outer casing is provided with a first inclined surface, and the bottom outer wall of the outer casing is provided with a second inclined surface that matches the first inclined surface.

[0009] Furthermore, the sidewall of the mounting plate is provided with evenly distributed circular grooves, and the mounting hole is located at the center of the circular groove.

[0010] In the above technical solution, the fire-retardant exterior wall insulation material provided by this utility model has the following advantages: by wrapping the extruded polystyrene board with an outer shell and sealing the extruded polystyrene board inside the outer shell with foamed cement board, the exterior wall insulation material has a good insulation effect, high fire resistance, and is lightweight; by setting a circular groove on the outside of the mounting plate and placing the mounting hole in the center of the circular groove, the exterior wall insulation material can be installed using a nail gun, and the retaining ring of the nail can be located inside the circular groove, which has a high installation efficiency compared to the traditional method of drilling holes and installing with expansion tubes and screws; by using the cooperation of the first and second inclined surfaces of the upper and lower insulation materials, rainwater is less likely to seep into the wall surface through the gap between the upper and lower insulation materials, thus achieving a good waterproof effect for the exterior wall insulation material.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-3As shown in the figure, the fireproof and flame-retardant exterior wall insulation material provided by this utility model includes an outer shell 1, a decorative layer 2 is provided on one side of the outer wall of the outer shell 1, an extruded polystyrene board 5 and a foamed cement board 6 are provided inside the outer shell 1, the foamed cement board 6 is located on the side of the extruded polystyrene board 5 away from the decorative layer 2, the outer wall of the foamed cement board 6 away from the extruded polystyrene board 5 is provided with a corrugated pattern 9, and the outer wall of the extruded polystyrene board 5 is provided with a fireproof and permeable layer 14.

[0018] Specifically, in this embodiment, the shell includes an outer casing 1 made of aluminum alloy. A decorative layer 2, which is a fluorocarbon coating, is provided on one side of the outer wall of the outer casing 1. The interior of the outer casing 1 contains an extruded polystyrene (XPS) board 5 and a foamed cement board 6. The outer casing 1 encloses the XPS board 5 and the foamed cement board 6. Compared to using sprayed stone paint, the fluorocarbon coating on the outer casing 1 is lighter. The foamed cement board 6 is located on the side of the XPS board 5 furthest from the decorative layer 2, and the thickness of the XPS board 5 is approximately three times that of the foamed cement board 6. This is because the XPS board 5 is lightweight and has good thermal insulation properties, while the foamed cement board 6 has good fire resistance but is heavier. This design effectively combines the advantages of both materials. The advantages of this material are that it achieves good fire resistance and thermal insulation performance. The outer wall of the foamed cement board 6 away from the extruded polystyrene board 5 is provided with a wavy pattern 9. The wavy pattern 9 increases its contact area with the adhesive, making the thermal insulation material more firmly bonded when bonded with adhesive. The outer wall of the extruded polystyrene board 5 is provided with a fireproof penetrating layer 14. The penetrating layer 14 is formed by the penetration of fireproof coating into the outer wall of the extruded polystyrene board 5. The specific construction method is as follows: First, make several micro holes on the outer wall of the extruded polystyrene board 5. The depth of the micro holes is 1-3cm. Then, immerse the extruded polystyrene board 5 in fireproof coating for 2-5 hours. The fireproof coating can then enter the micro holes to form the penetrating layer 14. Then, take it out and let it dry.

[0019] This utility model provides a fireproof and flame-retardant exterior wall insulation material, in which an extruded polystyrene board 5 is wrapped by an outer shell 1, and a foamed cement board 6 is used to seal the extruded polystyrene board 5 inside the outer shell 1, so that the exterior wall insulation material has good insulation effect, high fire resistance, and lightweight.

[0020] In another embodiment of this utility model, an adhesive layer 7 is provided between the extruded polystyrene board 5 and one inner wall of the outer shell 1, and an adhesive layer 8 is provided between the extruded polystyrene board 5 and the foamed cement board 6. Both the adhesive layer 8 and the adhesive layer 7 are formed after the adhesive is dried, so that the extruded polystyrene board 5 and the foamed cement board 6 can be fixed inside the outer shell 1.

[0021] In another embodiment of this utility model, the top outer wall of the outer shell 1 is integrally formed with an installation plate 3, and the side wall of the installation plate 3 is provided with evenly distributed installation holes 4. The bottom outer wall of the outer shell 1 is provided with a relief groove 12 that is adapted to the installation plate 3. The installation plate 3 and the relief groove 12 cooperate to make the upper and lower insulation materials fit together more closely. The top outer wall of the outer shell 1 is provided with an insertion groove 10, and the bottom outer wall of the outer shell 1 is provided with an insertion plate 11. In use, the insertion plate 11 at the bottom of the second insulation material is inserted into the insertion groove 10 at the top of the first insulation material, and then the second insulation material is attached to the wall.

[0022] In another embodiment of this utility model, the top outer wall of the outer shell 1 is provided with a slope 15, and the bottom outer wall of the outer shell 1 is provided with a slope 16 that matches the slope 15. By cooperating with the slope 15 and the slope 16 of the upper and lower insulation materials, rainwater is less likely to seep into the wall surface from the gap between the upper and lower insulation materials, thus achieving a better waterproof effect for the exterior wall insulation material. The side wall of the mounting plate 3 is provided with evenly distributed circular grooves 13, and the mounting hole 4 is located in the center of the circular groove 13. By setting the circular groove 13 on the outside of the mounting plate 3 and placing the mounting hole 4 in the center of the circular groove 13, the exterior wall insulation material can be installed using a nail gun. The retaining ring of the nail can be located inside the circular groove 13. Compared with the traditional method of drilling holes and then installing with expansion tubes and screws, this method has a high installation efficiency.

[0023] Working principle: When using, apply adhesive to the wall surface to be covered, and horizontally bond one side of the foamed cement board 6 of the first insulation material to the wall surface. Then, use a nail gun to aim at the mounting hole 4 and fire, so that the nail passes through the mounting hole 4 and drives into the interior of the wall. At this time, the retaining ring on the nail will be located inside the circular groove 13. Then, place the second insulation material on top of the first insulation material. After applying adhesive to the wall surface, insert the bottom plug plate 11 of the second insulation material into the top plug groove 10 of the first insulation material. Then, attach the second insulation material to the wall surface and fix the second insulation material with nails. The installation can be completed by repeating this process.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
