Technical Field

[0001] This utility model relates to the technical field of foamed sponge insulation boards, specifically a foamed sponge insulation board with flame-retardant function. Background Technology

[0002] Insulation boards are widely used in industries such as construction and refrigerated transportation. While traditional foamed sponge insulation boards possess some insulation properties, they are significantly lacking in flame retardancy. They are easily ignited by open flames, posing a significant risk of fire spread and threatening life and property. Furthermore, the stability of the connection structure during installation is poor, leading to loosening and displacement during use, resulting in a decrease in insulation performance. In addition, some insulation boards have unreasonable internal structural designs, failing to fully utilize the material's properties. Therefore, those skilled in the art have developed a foamed sponge insulation board with flame-retardant properties to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this utility model is to provide a foamed sponge insulation board with flame-retardant function to solve the problems mentioned in the background art.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the present invention, a flame-retardant foamed sponge insulation board has an insulation board body 1 as its core structure. One end of the insulation board body 1 has a splicing groove 6, and the other end has a splicing insert 7, with a limiting groove 8 on the splicing insert 7. Simultaneously, the outer surface of the insulation board body 1 near the splicing groove 6 has a limiting slot 5, inside which a fixing insert 4 is inserted. The fixing insert 4 consists of an insert rod 16 and a cover plate 17. The size of the insert rod 16 matches the limiting slot 5, and threaded grooves are provided on the sides of the insert rod 16 and the splicing insert 7. This splicing structure design allows adjacent insulation boards to interlock with each other through the splicing groove 6 and the splicing insert 7. Then, the fixing insert 4 is inserted into the limiting slot 5. At this time, the fixing insert 4 passes through the limiting groove 8 of the adjacent insulation board to achieve limiting. The insulation board body 1 and the fixing insert 4 are fixedly connected by fixing screws 3, further reinforcing the splicing joint and preventing the insulation board from loosening or falling off during use.

[0021] Both sides of the insulation board 1 are covered with flame-retardant boards 13, and a first isolation board 9 and a second isolation board 14 are arranged in parallel inside. Foamed sponge 12 is filled between the first isolation board 9 and the second isolation board 14 to fully utilize the excellent insulation performance of the foamed sponge. Flame-retardant polystyrene particles 11 are filled between the first isolation board 9 and the flame-retardant board 13, and between the second isolation board 14 and the flame-retardant board 13, effectively improving the overall flame retardancy of the insulation board. A second connecting rod 15 is provided on the first isolation board 9, and a first connecting rod 10 is provided on the second isolation board 14. The first connecting rod 10 passes through the first isolation board 9 and is fixedly connected to the left inner wall of the flame-retardant board 13, while the second connecting rod 15 passes through the second isolation board 14 and is fixedly connected to the right inner wall of the flame-retardant board 13. The alternating arrangement of the first connecting rod 10 and the second connecting rod 15 not only provides space for the filler but also provides support, enhancing the connection strength and stability between the structural layers.

[0022] In addition, both outer surfaces of the flame-retardant board 13 are provided with outer protective panels 2 made of rock wool board. Rock wool board is non-combustible and resistant to high temperature, which further enhances the flame-retardant performance and protective ability of the insulation board. The flame-retardant board 13 is made of polyurethane, which has good heat insulation and certain flame retardancy. It works in synergy with other structures to improve the overall performance of the insulation board.

[0023] During production, the insulation board 1 is first prepared. A splicing groove 6 is machined at one end of the insulation board 1, and a splicing insert 7 is made at the other end with a limiting groove 8. A limiting slot 5 is machined on the outer surface near the splicing groove 6. The insert rod 16 and the cover plate 17 are assembled into a fixed insert 4, and threaded grooves are machined on the sides of the insert rod 16 and the splicing insert 7.

[0024] A flame-retardant board 13 is made of polyurethane and covers both sides of the insulation board 1. An outer protective panel 2 is made of rock wool and installed on the outer surface of the flame-retardant board 13. A first isolation panel 9 and a second isolation panel 14 are installed parallel to each other inside the insulation board 1. Foamed sponge 12 is filled between the first isolation panel 9 and the second isolation panel 14. Flame-retardant polystyrene particles are filled between the first isolation panel 9 and the flame-retardant board 13, and between the second isolation panel 14 and the flame-retardant board 13. A first connecting rod 10 and a second connecting rod 15 are fixed to the second isolation panel 14 and the first isolation panel 9, respectively, and are fixedly connected to the inner wall of the flame-retardant board 13 through the corresponding isolation panels, ensuring alternating installation.

[0025] During installation and use, insert the splicing plate 7 of the adjacent insulation board into the splicing groove 6 of another insulation board. After the initial splicing, insert the rod 16 of the fixing plate 4 into the limiting slot 5. At this time, the rod 16 passes through the limiting groove 8 of the adjacent insulation board. Finally, tighten the fixing screw 3 through the threaded groove to complete the stable splicing and realize the construction of insulation walls and other structures.
