Description

Technical Field

[0001] This application belongs to the technical field of fireproof board structures, specifically relating to a sound-absorbing fireproof board. Background Technology

[0002] Fire-resistant boards, also known as fire-resistant panels, are scientifically called thermosetting resin-impregnated paper high-pressure laminates (HPL). They are fire-resistant building materials used for surface decoration, offering a wide variety of colors, textures, and unique physical properties. Fire-resistant boards are widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, and exterior walls. However, most existing fire-resistant boards prioritize hardness and haven't fully considered their sound insulation capabilities. Utility Model Content

[0003] The purpose of this application is to provide a sound-absorbing and fireproof board that addresses the shortcomings of existing technologies. In practical applications, by setting sound-absorbing holes of different diameters, it can absorb sound of different wavelengths and achieve better sound insulation.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A sound-absorbing and fireproof board includes a first board assembly and a second board assembly laminated together. The first board assembly and the second board assembly are respectively provided with a plurality of first sound-absorbing holes and a plurality of second sound-absorbing holes. The diameter of the first sound-absorbing holes is larger than the diameter of the second sound-absorbing holes. The first board assembly includes a calcium silicate board and a flame-retardant layer laminated together. The second board assembly includes an aluminum foil layer and a natural wood veneer layer laminated together. The aluminum foil layer is connected to the flame-retardant layer.

[0006] As an improvement to the sound-absorbing and fireproof board described in this application, the diameter of the first sound-absorbing hole is set to 4 mm to 7 mm, and a plurality of the first sound-absorbing holes are arranged in an array on the first board assembly with equal spacing of 30 mm to 50 mm.

[0007] As an improvement to the sound-absorbing and fireproof board described in this application, the diameter of the second sound-absorbing hole is set to 0.1 mm to 0.2 mm, and a plurality of the second sound-absorbing holes are arranged in an array on the second board assembly with equal spacing between 2 mm and 5 mm.

[0008] As an improvement to the sound-absorbing and fireproof board described in this application, the sound-absorbing and fireproof board further includes a fireproof paint layer coated on the side of the natural wood veneer layer away from the aluminum foil layer.

[0009] As an improvement to the sound-absorbing and fireproof board described in this application, the thickness of the first board assembly is greater than the thickness of the second board assembly, and the thickness of the aluminum foil layer is less than the thickness of the natural wood veneer layer.

[0010] The beneficial effects of this application are as follows: In actual use, by setting sound-absorbing holes of different diameters on different board layers, different wavelengths of sound can be absorbed, resulting in better sound insulation; at the same time, the aluminum foil layer in this application can increase the toughness and strength of the second board assembly, while further improving the fire resistance of the sound-absorbing fireproof board.

[0025] Implementation

[0026] A sound-absorbing and fireproof board includes a first board assembly 1 and a second board assembly 2 that are laminated together. The first board assembly 1 and the second board assembly 2 are respectively provided with a plurality of first sound-absorbing holes 11 and a plurality of second sound-absorbing holes 21. The diameter of the first sound-absorbing holes 11 is larger than the diameter of the second sound-absorbing holes 21. The first board assembly 1 includes a calcium silicate board 12 and a flame-retardant layer 13 that are laminated together. The second board assembly 2 includes an aluminum foil layer 22 and a natural wood veneer layer 23 that are laminated together. The aluminum foil layer 22 is connected to the flame-retardant layer 13.

[0027] In practical applications, the side of the calcium silicate board 12 away from the second board assembly 2 is used for installation on the surface of objects requiring protection, such as walls or boxes. The setting of first sound-absorbing holes 11 and second sound-absorbing holes 21 with different diameters can absorb sound of different wavelengths, resulting in better sound insulation. At the same time, the setting of the aluminum foil layer 22 in this application can increase the toughness and strength of the second board assembly 2, while further improving the fire resistance of the sound-absorbing fireproof board.

[0028] Specifically, the diameter of the first sound-absorbing hole 11 is set to 4 mm to 7 mm, and multiple first sound-absorbing holes 11 are arranged in an array on the first plate assembly 1 with equal spacing of 30 mm to 50 mm; the diameter of the second sound-absorbing hole 21 is set to 0.1 mm to 0.2 mm, and multiple second sound-absorbing holes 21 are arranged in an array on the second plate assembly 2 with equal spacing of 2 mm to 5 mm.

[0029] In this embodiment, the diameter of the first sound-absorbing hole 11 is 6 mm, the spacing between each first sound-absorbing hole 11 is 40 mm, the diameter of the second sound-absorbing hole 21 is 0.2 mm, and the spacing between each second sound-absorbing hole 21 is 3 mm. The above settings can achieve better sound absorption effect. It is understood that the selection of its diameter and spacing can also be adapted within the above settings according to the specific usage environment.

[0030] Specifically, the sound-absorbing fireproof board also includes a fireproof paint layer 3, which is coated on the side of the natural wood veneer layer 23 away from the aluminum foil layer 22 to further increase the fireproof performance.

[0031] Specifically, the thickness of the first board assembly 1 is greater than the thickness of the second board assembly 2, and the thickness of the aluminum foil layer 22 is less than the thickness of the natural wood veneer layer 23. In this embodiment, the thickness of the calcium silicate board 12 is set to 9 mm, the thickness of the flame retardant layer 13 is set to 5 mm, the thickness of the aluminum foil layer 22 is set to 0.2 mm, and the thickness of the natural wood veneer layer 23 is set to 0.3 mm. It can be understood that the selection of its thickness can also be adapted to the specific use environment.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or variations made by those skilled in the art based on this application are within the scope of protection of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
