Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing panels, specifically a heat-insulating polyester fiber sound-absorbing panel. Background Technique

[0002] The polyester fiber sound-absorbing panel is a sound-insulating material mainly made of polyester fiber, with excellent sound absorption performance. It effectively reduces the reflection and propagation of sound waves through the staggered arrangement of fibers and the porous structure, reducing indoor echo and noise. It is light and easy to install, and is widely used for acoustic optimization in places such as offices, meeting rooms, and home theaters.

[0003] After retrieval, it is found that the Chinese patent with the publication number CN217353306U discloses a polyester fiber sound-absorbing panel with good moisture-proof performance, belonging to the technical field of ecological panels. The polyester fiber sound-absorbing panel with good moisture-proof performance includes a panel body. Grooves are provided on the surface of the panel body, and a moisture-absorbing component is placed inside the grooves for absorbing moisture inside the panel body. The moisture-absorbing component is installed through a connecting component, so that the moisture-absorbing component can be stable and not easily fall off. By setting the moisture-absorbing component, the moisture inside the panel body is absorbed, the moisture content inside the panel body is reduced, correspondingly reducing the possibility of deformation, mildew, and insect infestation of the panel body, and at the same time being more adaptable to a humid use environment. At the same time, the moisture-absorbing component is installed using a clamping strip and a clamping groove, and its installation method is simple and relatively firm, with a wider scope of application.

[0004] The above-mentioned utility model has the following problems:

[0005] 1. For the existing polyester fiber sound-absorbing panels, only the sound absorption effect of the polyester fiber sound-absorbing panel itself is processed, and the sound absorption effect is limited, reducing the noise reduction and sound insulation effect, and the fire prevention effect is poor, unable to effectively block the fire source, reducing its practicability.

[0006] Therefore, the technical personnel in this field provide a heat-insulating polyester fiber sound-absorbing panel to solve the problems raised in the above background technique. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a heat-insulating polyester fiber sound-absorbing panel to solve the problems raised in the above background technique.

[0009] The heat-insulating polyester fiber sound-absorbing panel includes a sound-absorbing layer, a sound-insulating layer, a heat-insulating layer, a first flame-retardant layer, and a second flame-retardant layer. The upper surface of the sound-absorbing layer is fixedly connected to the sound-insulating layer, the upper surface of the sound-insulating layer is fixedly connected to the heat-insulating layer, the lower surface of the sound-absorbing layer is fixedly connected to the first flame-retardant layer, and the upper surface of the heat-insulating layer is fixedly connected to the second flame-retardant layer.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The sound-absorbing layer made of polyester fiber material can effectively absorb sound waves through its porous structure and staggered arrangement of fibers. When sound waves enter the board, friction and vibration will occur between the fibers, converting sound energy into heat energy, thereby reducing reflection and transmission and achieving sound absorption. The sound-insulating layer made of foam polyurethane material has excellent heat insulation performance and can effectively block the conduction of heat and sound, which is used to improve the heat preservation and sound insulation effects and achieve sound insulation. Through sound absorption and sound insulation treatment, the noise reduction and sound insulation effects are guaranteed. At the same time, it also has excellent shock absorption and buffering performance, which can effectively reduce the impact of vibration and shock on the structure, indirectly increasing the structural strength. The heat-insulating layer made of polystyrene resin has a closed-cell structure, reducing the heat exchange between the building and the external environment, providing good heat preservation effects, and having high mechanical properties such as compressive and flexural strength, capable of withstanding a certain load and increasing the overall structural strength. The first flame-retardant layer and the second flame-retardant layer made of polyurethane material have good flame-retardant performance, can effectively avoid rapid combustion, greatly improve the fire resistance of the sound-absorbing board, effectively prevent the spread of fire, reduce potential safety hazards, and increase the practicability of the sound-absorbing board.
