Description

Technical Field

[0001] This utility model belongs to the field of XPS extruded polystyrene board, specifically a multifunctional XPS extruded polystyrene board. Background Technology

[0002] XPS extruded polystyrene board is a high-performance thermal insulation material made from polystyrene resin as the main raw material through processes such as heating and mixing and extrusion molding. Its unique closed-cell structure gives it excellent thermal insulation performance, high strength, and good waterproof and moisture-proof performance. It is widely used in building exterior wall insulation, roof insulation, ground moisture-proofing, cold storage insulation, pipeline insulation and other fields.

[0003] Because XPS (extruded polystyrene) is a flammable material, it will burn when exposed to high temperatures or fire sources, causing the boards to ignite and potentially leading to fires. In addition, the high strength of XPS extruded boards makes them relatively brittle, and they may break under heavy loads or prolonged high pressure, thus reducing their effectiveness.

[0004] In summary, this utility model provides a multifunctional XPS extruded board to solve the above problems. Utility Model Content

The top layer includes a first flame-retardant layer, a first mesh layer, and a surface layer. The first flame-retardant layer, the first mesh layer, and the surface layer are bonded together with a composite adhesive. The bottom layer includes a second flame-retardant layer, a sound-insulating layer, and a second mesh layer. The second flame-retardant layer, the sound-insulating layer, and the second mesh layer are bonded together with a composite adhesive.

[0019] Example 1

[0020] like Figure 1-3 As shown, this is the first embodiment of the present invention. This embodiment provides a multifunctional XPS extruded board, including an XPS extruded board assembly 1. The XPS extruded board assembly 1 includes an intermediate layer 11, a top layer 12, and a bottom layer 13. The top layer 12 is located on the front side of the intermediate layer 11, and the bottom layer 13 is located on the back side of the intermediate layer 11. The top layer 12 includes a first flame-retardant layer 121, a first mesh layer 122, and a surface layer 123. The first flame-retardant layer 121, the first mesh layer 122, and the surface layer 123 are bonded together by a composite adhesive. The bottom layer 13 includes a second flame-retardant layer 131, a sound-insulating layer 132, and a second mesh layer 133. The second flame-retardant layer 131, the sound-insulating layer 132, and the second mesh layer 133 are bonded together by a composite adhesive. Both the top layer 12 and the bottom layer 13 are bonded to the intermediate layer 11 by a composite adhesive.

[0021] like Figure 1-3 As shown, the intermediate layer 11 effectively blocks heat transfer through its closed-cell honeycomb structure. By setting the first flame-retardant layer 121, the second flame-retardant layer 131, and the sound insulation layer 132, it helps to prevent the occurrence and spread of fire. The sound insulation layer 132 also has a certain sound absorption effect, thereby improving the sound insulation effect. The waterproof and moisture-proof capability of the surface layer 123 can prevent moisture intrusion and ensure the long-term stability of thermal insulation performance. Through the reinforcement of the second grid layer 133 and the first grid layer 122, the overall structural strength of XPS extruded board is enhanced, and the crack resistance and compressive strength are improved, thereby extending its service life. Through the multi-layer composite structure of the intermediate layer 11, the top layer 12, and the bottom layer 13, XPS extruded board achieves multiple functions of fire resistance, moisture resistance, and crack resistance, meeting the needs of diverse application scenarios.

[0022] Example 2

[0023] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] The sound insulation layer 132 is made of rock wool, the surface layer 123 is made of aluminum foil, and the composite adhesive can be made of polyurethane adhesive.

[0026] The first flame-retardant layer 121 is bonded to the front side of the intermediate layer 11, the first mesh layer 122 is bonded to the surface of the first flame-retardant layer 121, and the top layer 123 is bonded to the surface of the first mesh layer 122.

[0028] like Figure 1-3 As shown, the intermediate layer 11 is formed by extruding polystyrene resin, foaming agent, stabilizer, antioxidant, catalyst, plasticizer and colorant through an extruder. The first flame retardant layer 121 and the second flame retardant layer 131 are bonded to the surface of the intermediate layer 11 with composite adhesive. The first mesh layer 122 is bonded to the surface of the first flame retardant layer 121 with composite adhesive. The top layer 123 is bonded to the surface of the top layer 123 with composite adhesive. The sound insulation layer 132 is bonded to the surface of the second flame retardant layer 131 with composite adhesive. The second mesh layer 133 is bonded to the surface of the sound insulation layer 132 with composite adhesive. After each layer is bonded, a certain pressure needs to be applied to ensure that the bonding is seamless. After bonding, the excess adhesive around the bonding layer needs to be scraped off to improve the appearance quality of the XPS extruded board.

[0029] In use, the first flame-retardant layer 121 and the second flame-retardant layer 131 are bonded to the surface of the intermediate layer 11 with a composite adhesive. The first mesh layer 122 is bonded to the surface of the first flame-retardant layer 121 with a composite adhesive. The top layer 123 is bonded to the surface of the top layer 123 with a composite adhesive. The sound insulation layer 132 is bonded to the surface of the second flame-retardant layer 131 with a composite adhesive. The second mesh layer 133 is bonded to the surface of the sound insulation layer 132 with a composite adhesive. After each layer is bonded, a certain pressure needs to be applied to ensure that the bonding is seamless. The intermediate layer 11, through its closed-cell honeycomb structure, effectively blocks the transfer of heat. By setting the first flame-retardant layer 121 and the second flame-retardant layer 122, the heat transfer is effectively blocked. The first grid layer 122 and the second grid layer 133 help prevent the occurrence and spread of fire. The second grid layer 133 and the first grid layer 122 strengthen the overall structure of the XPS extruded board, improve its crack resistance and compressive strength, and extend its service life. Through the multi-layer composite structure of the middle layer 11, the top layer 12 and the bottom layer 13, the XPS extruded board achieves multiple functions such as fire resistance, moisture resistance and crack resistance, and meets the needs of diverse application scenarios.
