Description

Technical Field

[0001] This utility model relates to the field of phenolic insulation board technology, and in particular to a composite phenolic insulation board. Background Technology

[0002] With increasing emphasis on building energy conservation and fire safety, phenolic insulation boards, thanks to their excellent fire resistance (Class A non-combustible) and low thermal conductivity (as low as 0.025 W / (m·K), are widely used in building exterior wall insulation, cold chain warehousing, and industrial pipeline insulation. Especially in high-rise buildings, hospitals, schools, and other densely populated areas, the fire safety of phenolic insulation boards is a key advantage. However, with the accelerating pace of building industrialization, prefabricated buildings and integrated prefabricated insulation components place higher demands on the mechanical properties and dimensional stability of insulation materials, gradually revealing the structural drawbacks of traditional phenolic insulation boards.

[0003] Currently, most commercially available phenolic insulation boards are composite structures consisting of a phenolic foam core and a surface reinforcement layer (such as fiberglass mesh or inorganic fiberboard). While this structure improves surface strength to some extent, it suffers from significant performance defects due to the lack of an internal support system: Firstly, it has insufficient tensile and shear strength in the plane, making it prone to breakage and damage under alternating positive and negative wind pressure or construction impacts; secondly, it has poor support stiffness in the thickness direction, making it susceptible to irreversible compressive deformation under long-term loads when used in load-bearing applications such as roofs and floors, leading to a decline in insulation performance. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a composite phenolic insulation board, which solves the problem mentioned in the background art that most commercially available phenolic insulation boards are composite structures of phenolic foam body and surface reinforcement layer (such as fiberglass mesh or inorganic fiberboard). Although this structure improves surface strength to some extent, it has significant performance defects due to the lack of an internal support system.

[0008] As a further embodiment of this utility model, a water-repellent layer A is provided on the top of the phenolic insulation board body, and a water-repellent layer B is provided on the bottom of the phenolic insulation board body. The water-repellent layer B serves to achieve waterproofing.

[0009] As a further embodiment of this utility model, a fibrous mesh layer A is provided on the top of the hydrophobic layer A, and a fibrous mesh layer B is provided on the bottom of the hydrophobic layer B. The fibrous mesh layer B enhances the structural strength.

[0010] As a further embodiment of this utility model, a top plate is provided on the top of the fiber mesh layer A, and a bottom plate is provided on the bottom of the fiber mesh layer B. The top plate and the bottom plate together serve to seal the main body of the phenolic insulation board.

[0011] As a further embodiment of this utility model, an aluminum foil layer A is fixedly connected to the top of the top plate, and an aluminum foil layer B is fixedly connected to the bottom of the bottom plate. The aluminum foil layer A and the aluminum foil layer B serve to provide waterproofing.

[0013] As a further embodiment of this utility model, an adhesive layer is provided at the bottom of the base plate. The adhesive layer is adhesively connected to the external wall, thereby fixing the equipment to the external wall.

[0014] (III) Beneficial Effects

[0015] This utility model provides a composite phenolic insulation board, which has the following beneficial effects:

[0016] 1. This composite phenolic insulation board, through the setting of the reinforcement mechanism, has a placement groove inside the main body of the phenolic insulation board. The placement groove is equipped with several transverse and longitudinal reinforcing ribs, which are cross-woven to form a mesh structure. When the main body of the phenolic insulation board is subjected to external force, the mesh structure composed of transverse and longitudinal reinforcing ribs can quickly disperse the stress to the entire insulation board, avoid damage caused by local stress concentration, and extend the service life of the insulation board.

[0017] 2. This composite phenolic insulation board, through the setting of the sealing mechanism, requires multiple phenolic insulation board bodies to be assembled together during use. Due to the gaps between the phenolic insulation board bodies during the assembly process, the sealing performance of the phenolic insulation board bodies is poor. Therefore, rubber sealing gaskets are set around the phenolic insulation board bodies, and support springs are set inside the rubber sealing gaskets for support. This allows the phenolic insulation board bodies to be tightly fitted together, thereby improving the sealing performance of the equipment, preventing heat loss, moisture intrusion, and air penetration, and ensuring the stability of insulation performance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a composite phenolic insulation board, including a phenolic insulation board body 1, with a placement groove inside the phenolic insulation board body 1, and a reinforcing mechanism 2 installed inside the placement groove. By setting the reinforcing mechanism 2, damage caused by local stress concentration is avoided, and the service life of the insulation board is extended. Sealing mechanisms 3 are set around the surface of the phenolic insulation board body 1. By setting the sealing mechanism 3, the sealing effect of the equipment is improved, heat loss, water vapor intrusion and air penetration are avoided, and the stability of the insulation performance is ensured.

[0025] The reinforcement mechanism 2 includes several transverse reinforcing ribs 201 installed inside the placement groove, and several longitudinal reinforcing ribs 202 installed at the bottom of the transverse reinforcing ribs 201.

[0026] The sealing mechanism 3 includes a rubber sealing gasket 301 disposed around the phenolic insulation board body 1, and a support spring 302 is installed inside the rubber sealing gasket 301.

[0027] A water-repellent layer A4 is provided on the top of the phenolic insulation board body 1, and a water-repellent layer B5 is provided on the bottom of the phenolic insulation board body 1. The water-repellent layer B5 serves to waterproof the board.

[0028] A fiber mesh layer A6 is provided on the top of the hydrophobic layer A4, and a fiber mesh layer B7 is provided on the bottom of the hydrophobic layer B5. The fiber mesh layer B7 enhances the structural strength.

[0029] A top plate 8 is provided on the top of the fiber mesh layer A6, and a bottom plate 9 is provided on the bottom of the fiber mesh layer B7. The top plate 8 and the bottom plate 9 serve to seal the phenolic insulation board body 1.

[0030] An aluminum foil layer A10 is fixedly connected to the top of the top plate 8, and an aluminum foil layer B11 is fixedly connected to the bottom of the bottom plate 9. The aluminum foil layers A10 and B11 serve to waterproof the surface.

[0031] The transverse reinforcing ribs 201 and longitudinal reinforcing ribs 202 are made of basalt fiber. The transverse reinforcing ribs 201 and longitudinal reinforcing ribs 202 are interwoven to form a mesh structure. The setting of transverse reinforcing ribs 201 and longitudinal reinforcing ribs 202 plays a role in improving the strength of the internal structure.

[0032] The bottom of the base plate 9 is provided with an adhesive layer, which is adhesively connected to the external wall. The adhesive layer serves to fix the equipment to the external wall.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When in use, the phenolic insulation board body 1 has a placement groove inside, and several transverse reinforcing ribs 201 and longitudinal reinforcing ribs 202 are installed inside the placement groove. The transverse reinforcing ribs 201 and longitudinal reinforcing ribs 202 are cross-woven to form a mesh structure. When the phenolic insulation board body 1 is subjected to external force, the mesh structure composed of transverse reinforcing ribs 201 and longitudinal reinforcing ribs 202 can quickly disperse the stress to the entire insulation board.

[0035] The second step: When using the product, multiple phenolic insulation board bodies 1 need to be assembled together. Since there will be gaps between the phenolic insulation board bodies 1 during the assembly process, the sealing performance of the phenolic insulation board bodies 1 is poor. Therefore, rubber sealing gaskets 301 are set around the phenolic insulation board bodies 1, and support springs 302 are set inside the rubber sealing gaskets 301 for support, so that the phenolic insulation board bodies 1 can be tightly fitted together.
