Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing panel technology, specifically a heat-insulating polyester fiber sound-absorbing panel. Background Technology

[0002] Polyester fiber acoustic panels are a type of material made from polyester fiber through hot pressing, which combines sound absorption and decoration functions. They are widely used in places with high requirements for acoustic environment, such as concert halls, theaters, KTVs, and recording studios. They are also suitable for public spaces such as conference rooms, exhibition halls, hotel lobbies, restaurants, and shopping malls, as well as living rooms, bedrooms, and home theaters in home decoration. They can improve the acoustic environment and play a decorative role.

[0003] Existing polyester fiber sound-absorbing panels are installed using adhesive, which often results in them detaching after installation, and gaps between the panels also affect sound insulation. Therefore, we propose a thermal insulation polyester fiber sound-absorbing panel. Utility Model Content

[0004] The purpose of this invention is to provide a heat-insulating polyester fiber sound-absorbing board, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat-insulating polyester fiber sound-absorbing board, comprising a board body, wherein an mounting plate is integrally formed on one side wall of the board body, and a notch is provided at the bottom of the other side wall of the board body;

[0006] The board includes a first sound-absorbing layer, a second sound-absorbing layer, and a thermal insulation layer installed between the first sound-absorbing layer and the second sound-absorbing layer. The surface of the thermal insulation layer is provided with honeycomb holes.

[0007] By adopting the above technical solution, the first and second sound-absorbing layers can achieve good sound absorption effect, and the setting of the thermal insulation cotton layer can improve the thermal insulation performance. Furthermore, the honeycomb holes on the surface of the thermal insulation cotton layer can further enhance the sound absorption effect. During installation, the mounting plate can be used to easily fix it with bolts, and the notch on the other side of the plate can cover the adjacent mounting plate, thereby covering the installation area and helping to avoid gaps that may affect the sound insulation effect.

[0008] In a preferred embodiment of this utility model, both the first sound-absorbing layer and the second sound-absorbing layer are composite material layers of modified polyester fiber and nano-silica aerogel.

[0009] By adopting the above technical solution, nano-silica aerogel has extremely high porosity and extremely low thermal conductivity. When combined with polyester fiber, it can not only retain the good sound absorption and mechanical properties of polyester fiber, but also significantly improve the thermal insulation performance of the board.

[0010] In a preferred embodiment of this utility model, a flame-retardant layer is installed on the outer wall of the second sound-absorbing layer.

[0011] By adopting the above technical solution, the flame retardant layer is a polyurethane material layer, which can improve the overall flame retardant performance of the board.

[0012] In a preferred embodiment of this utility model, the outer wall of the flame-retardant layer is coated with a protective coating.

[0013] By adopting the above technical solution, the protective coating is composed of water-based polyurethane resin, nano antibacterial agent and infrared reflector. Water-based polyurethane resin, as a film-forming substance, has good weather resistance and adhesion, and can protect the surface of the board from external environmental erosion. Nano antibacterial agent can effectively inhibit the growth and reproduction of bacteria and mold, and prevent the board from breeding microorganisms and producing odors in a humid environment. Infrared reflector can reflect infrared rays in sunlight, reduce heat absorption, and further improve the thermal insulation performance of the board.

[0014] In a preferred embodiment of this utility model, mounting holes are provided on both sides of the top of the mounting plate.

[0015] By adopting the above technical solution, the mounting holes are designed to facilitate fixing using bolts passing through them.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application provides a heat-insulating polyester fiber sound-absorbing panel, which has an integrally formed mounting plate on one side wall of the panel and a notch on the lower side of the other side of the panel. The mounting plate has mounting holes for easy fixing with bolts. The notch on the other side of the panel can cover the adjacent mounting plate, thus covering the installation area and helping to avoid gaps that may affect the sound insulation effect.

[0018] The insulation cotton layer installed between the first and second sound-absorbing layers improves the insulation performance. The surface of the insulation cotton layer has honeycomb pores, which further enhances the sound absorption effect. Both the first and second sound-absorbing layers are made of modified polyester fiber and nano-silica aerogel composite material, which further improves the sound absorption and insulation performance.

[0025] Please see Figure 1-3 The present invention provides a technical solution: a heat-insulating polyester fiber sound-absorbing board, including a board body 1, an installation plate 11 integrally formed on one side wall of the board body 1, and a notch 13 opened at the bottom of the other side wall of the board body 1;

[0026] The panel 1 includes a first sound-absorbing layer 14, a second sound-absorbing layer 16, and a thermal insulation layer 15 installed between the first sound-absorbing layer 14 and the second sound-absorbing layer 16. The surface of the thermal insulation layer 15 is provided with honeycomb holes.

[0027] It should be understood that in actual use, the first sound-absorbing layer 14 and the second sound-absorbing layer 16 can achieve good sound absorption effect, and the setting of the thermal insulation layer 15 can improve the thermal insulation performance. Furthermore, the honeycomb holes on the surface of the thermal insulation layer 15 can further improve the sound absorption effect. During installation, the mounting plate 11 can be used to fix it with bolts, and the notch 13 on the other side of the plate 1 can cover the adjacent mounting plate 11, thereby covering the installation area and helping to avoid gaps that may affect the sound insulation effect.

[0028] Furthermore, mounting holes 12 are provided on both sides of the top of the mounting plate 11. The mounting holes 12 are designed to facilitate fixing by using bolts through the mounting holes 12.

[0029] like Figure 1 and 2 As shown; the first sound-absorbing layer 14 and the second sound-absorbing layer 16 are both modified polyester fiber and nano silica aerogel composite material layers. Nano silica aerogel has extremely high porosity and extremely low thermal conductivity. After being combined with polyester fiber, it can not only retain the good sound absorption performance and mechanical properties of polyester fiber, but also greatly improve the thermal insulation performance of the board.

[0030] like Figure 1 and 2As shown; a flame-retardant layer 17 is installed on the outer wall of the second sound-absorbing layer 16. The flame-retardant layer 17 is a polyurethane material layer, which can improve the overall flame-retardant performance of the panel 1.

[0031] like Figure 2 and 3 As shown; the outer wall of the flame retardant layer 17 is coated with a protective coating 18, which is composed of water-based polyurethane resin, nano antibacterial agent and infrared reflector. The water-based polyurethane resin, as a film-forming substance, has good weather resistance and adhesion, and can protect the surface of the board from external environmental erosion; the nano antibacterial agent can effectively inhibit the growth and reproduction of bacteria and mold, and prevent the board from breeding microorganisms and producing odors in a humid environment; the infrared reflector can reflect infrared rays in sunlight, reduce heat absorption, and further improve the thermal insulation performance of the board.
