Description

Technical Field

[0001] This invention relates to the field of composite panels for building envelopes, specifically a sound-insulating, fire-resistant, and heat-insulating composite panel. Background Technology

[0002] The technology of building envelope composite panels specifically involves the preparation and application of integrated composite wall structures with multiple functions such as sound insulation, fireproofing, and heat insulation. It is widely used in various building interior and exterior walls, enclosure partitions, and building facade assembly scenarios.

[0003] Existing building wall insulation boards are mostly single-layer simple stacked structures, which are insufficient in terms of protection and durability; they lack dedicated fireproof and soundproof structures, flame-retardant synergistic designs and airtight insulation structures, resulting in poor noise reduction, fire prevention and insulation effects; moreover, the layers are loose and the joints are not tight, making it difficult to meet the needs of modern buildings. Summary of the Invention

[0004] To overcome the shortcomings of existing technical solutions, this invention provides a sound-insulating and fire-resistant composite insulation board, which can effectively solve the technical problems of existing insulation boards, which are mostly single-layer simple stacked structures with insufficient protection and durability; lack of dedicated fire-resistant and sound-insulating structure, flame-retardant synergistic design and airtight insulation structure, resulting in poor noise reduction, fire prevention and insulation effects; and loose layers and loose bonding, making it difficult to meet the technical needs of modern buildings.

[0005] The technical solution adopted by this invention to solve its technical problem is: a sound-insulating and fire-resistant composite insulation board, comprising an insulation board body, the insulation board body comprising a double-sided aluminum panel, a fire-resistant and sound-insulating interlayer, a core insulation layer, an adhesive layer, and a back panel layer, the double-sided aluminum panel being disposed on the outer side of the insulation board body, the back panel being disposed on the inner side of the insulation board body, the fire-resistant and sound-insulating interlayer and the core insulation layer being sequentially bonded together between the double-sided aluminum panel and the back panel layer via the adhesive layer, the fire-resistant and sound-insulating interlayer being provided with multi-level vibration damping and sound insulation support units on both sides inside the fire-resistant and sound-insulating interlayer, the multi-level vibration damping and sound insulation support units being provided with sound-absorbing cavities inside, the sound-absorbing cavities being filled with a composite layer of inorganic fiber felt and flame-retardant sound-insulating felt, the core insulation layer being made of flame-retardant insulation board, and the surface of the double-sided aluminum panel being provided with a protective coating.

[0006] Preferably, the top and bottom of the insulation board body are provided with horizontal edging, and both sides of the insulation board body are provided with vertical edging. Clamping blocks are provided on both sides of the horizontal and vertical edgings. A horizontal sealing gasket is provided on the inner side of the horizontal edging. An adhesive layer is provided at both ends of the horizontal sealing gasket. A vertical sealing gasket is provided on the inner side of the vertical edging. The adhesive layer matches the vertical sealing gasket.

[0007] The horizontal and vertical edging work together to fully wrap and protect the edges of the insulation board, preventing the main structure from being corroded by the external environment. The clamps can enhance the connection between the edging and the insulation board. The horizontal and vertical sealing gaskets are tightly bonded together through the adhesive layer, further improving the overall sealing performance and reducing the potential risks of sound insulation, fire prevention and heat preservation at the gaps.

[0008] Preferably, the outer side of the double-sided aluminum panel is provided with a fluorocarbon coating, and the outer side of the double-sided aluminum panel is provided with a decorative surface.

[0009] Fluorocarbon coating can effectively improve the weather resistance and corrosion resistance of double-sided aluminum panels, extend the service life of the panels, and also have a certain degree of stain resistance, making it easy to clean and maintain daily; the decorative surface can be adapted to different decoration styles according to the needs of actual use scenarios.

[0010] Preferably, the core insulation layer is made of one of rock wool board, rigid polyurethane foam board, and flame-retardant XPS extruded board.

[0011] All selected materials possess excellent flame-retardant properties, effectively preventing the spread of fire and ensuring safety. They also have good thermal insulation properties, reducing heat transfer between indoor and outdoor environments, lowering energy consumption, and adapting to the needs of use in different temperature environments.

[0012] Preferably, the inorganic fiber felt inside the sound-absorbing cavity is glass wool, and the flame-retardant sound-insulating felt is made of rubber.

[0013] Inorganic fiber felt made of glass wool has good sound absorption properties, which can effectively absorb sound waves and reduce noise transmission. Flame-retardant sound insulation felt made of rubber can further enhance the sound insulation effect of the fireproof and sound insulation interlayer, while also having a certain vibration reduction effect. Together with multi-level vibration reduction and sound insulation support units, it forms a multi-layer sound insulation and vibration reduction structure, which greatly improves the overall sound insulation performance of the insulation board.

[0014] Preferably, the adhesive layer is made of flame-retardant polyurethane adhesive, and the backing layer is made of either an aluminum alloy backing or a fireproof gypsum board.

[0015] Flame-retardant polyurethane adhesives not only have high bonding strength, enabling them to firmly bond double-sided aluminum panels, fireproof and soundproof interlayers, core insulation layers, and back panels into a whole, ensuring structural stability, but also possess excellent flame-retardant properties.

[0016] Preferably, both the horizontal and vertical edging are made of aluminum alloy, and the thickness of the horizontal and vertical edging is the same as the thickness of the double-sided aluminum panel.

[0017] Aluminum alloy material is lightweight, high-strength, corrosion-resistant, and flame-retardant. Its thickness is consistent with that of the double-sided aluminum panel, which can ensure that the overall surface of the insulation board is flat.

[0018] Preferably, the clamping block is made of aluminum alloy, and the clamping block, the horizontal edge, and the vertical edge are integrally formed, with anti-slip texture on the inner side of the clamping block.

[0019] The aluminum alloy clamps are integrally formed with the horizontal and vertical edging, which can enhance the overall structural strength of the edging, prevent the clamps from falling off, and ensure the protective effect of the edging on the insulation board. The anti-slip texture on the inside can increase the friction between the clamps and the insulation board, further improving the connection firmness.

[0020] Preferably, the adhesive layer is a pressure-sensitive adhesive layer, and the bonding surface between the adhesive layer and the vertical sealing gasket is provided with anti-slip protrusions to ensure a tight seal.

[0021] The pressure-sensitive adhesive layer facilitates installation and bonding without the need for additional adhesive. The anti-slip protrusions enhance the tightness of the bonding layer with the vertical sealing gasket, preventing gaps and further improving the overall sound insulation, fire resistance, and thermal insulation performance.

[0022] Preferably, a protective clip is movably engaged at the connection between the horizontal and vertical edging.

[0023] Protective plates can reinforce and protect the connection between horizontal and vertical edging, preventing the connection from loosening or deforming, while also covering the gaps at the connection, further improving the sealing, sound insulation and fireproofing effects.

[0024] Compared with existing technologies, the beneficial effects of this invention are as follows: Through the multi-layer integrated composite structure, the overall structural protection performance and durability can be improved by relying on double-sided aluminum panels and surface protective coatings. With the combination of fireproof and soundproof interlayer with internal multi-level vibration damping and soundproof support units and sound-absorbing cavities, external noise can be effectively blocked and absorbed, and the sound noise caused by vibration transmission can be weakened. At the same time, the composite layer filled inside the cavity and the flame-retardant material can significantly improve the overall fireproof and flame-retardant capabilities. The core insulation layer is made of flame-retardant insulation board combined with the bonding layer between each layer to form a stable and sealed insulation structure, effectively blocking the conduction of hot and cold air, and possessing excellent constant temperature insulation performance. The overall layer arrangement is reasonable and the structure is tightly combined, taking into account multiple functions such as sound insulation, fire prevention and insulation. The structure has strong stability, is suitable for use in various building walls and enclosure scenarios, has a longer service life and outstanding comprehensive practical effect.

The fire-resistant and sound-insulating interlayer 109 has multi-level vibration damping and sound insulation support units 112 on both sides inside. The multi-level vibration damping and sound insulation support units 112 have sound-absorbing cavities 114 inside.

The core insulation layer 110 is made of flame-retardant insulation board, and the surface of the double-sided aluminum panel 108 is provided with a protective coating.

[0033] The insulation board body 100 has horizontal edging 101 at the top and bottom, and vertical edging 102 on both sides.

[0034] The horizontal edging 101 and the vertical edging 102 work together to fully wrap and protect the edges of the insulation board body 100, preventing the main structure from being corroded by the external environment. The clamping block 104 can enhance the connection between the edging and the insulation board body 100. The horizontal sealing gasket 105 and the vertical sealing gasket 107 are tightly bonded together through the adhesive layer 106, further improving the overall sealing performance and reducing the potential hazards of sound insulation, fire prevention and heat insulation at the gaps.

[0037] The core insulation layer 110 uses one of the following: rock wool board, rigid polyurethane foam board, or flame-retardant XPS extruded board.

[0038] All selected materials possess excellent flame-retardant properties, effectively preventing the spread of fire and ensuring safety. They also have good thermal insulation properties, reducing heat transfer between indoor and outdoor environments, lowering energy consumption, and adapting to the needs of use in different temperature environments.

[0039] The inorganic fiber felt inside the sound-absorbing cavity 114 is made of glass wool, and the flame-retardant sound-insulating felt is made of rubber.

[0040] The inorganic fiber felt made of glass wool has good sound absorption properties, which can effectively absorb sound waves and reduce noise transmission. The flame-retardant sound insulation felt made of rubber can further enhance the sound insulation effect of the fireproof sound insulation interlayer 109, while also having a certain vibration reduction effect. Together with the multi-level vibration reduction and sound insulation support unit 112, it forms a multi-layer sound insulation and vibration reduction structure, which greatly improves the overall sound insulation performance of the insulation board.

[0046] The aluminum alloy clamping block 104 is integrally formed with the horizontal edge banding 101 and the vertical edge banding 102, which can enhance the overall structural strength of the edge banding, prevent the clamping block 104 from falling off, and ensure the protective effect of the edge banding on the insulation board body 100; the anti-slip texture on the inner side can increase the friction between the clamping block 104 and the insulation board body 100, further improving the connection firmness.

[0047] The adhesive layer 106 is a pressure-sensitive adhesive layer. The bonding surface between the adhesive layer 106 and the vertical sealing gasket 107 is provided with anti-slip protrusions to ensure a tight seal.

[0048] The pressure-sensitive adhesive layer 106 is easy to install and adhere without the need for additional adhesive.
