Description

Technical Field

[0001] This utility model relates to the field of building decoration materials technology, and in particular to a high sound insulation all-aluminum honeycomb wall panel. Background Technology

[0002] All-aluminum honeycomb panels are a new type of building material, mainly composed of two layers of aluminum plates and a honeycomb structure in the middle. The honeycomb structure in the middle is similar to the natural structure of a honeycomb, which allows all-aluminum honeycomb panels to provide good sound insulation and heat insulation while ensuring lightweight. Due to its lightweight, high strength, and environmentally friendly characteristics, it has gradually gained attention in the construction and decoration industries in recent years.

[0003] Currently, most aluminum honeycomb wall panels on the market rely on the single structure of the internal honeycomb core for sound insulation. The aluminum honeycomb core only blocks sound waves through its cavity structure and mainly reflects sound waves, lacking an active sound-absorbing structure. Its noise reduction effect is limited, making it unsuitable for some high-acoustic environments (such as recording studios, hospitals, etc.). Therefore, this utility model provides a high-sound-insulating all-aluminum honeycomb wall panel to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a high-sound-insulating all-aluminum honeycomb wall panel. A first sound-absorbing cotton is filled inside the honeycomb core, and the honeycomb core and the first sound-absorbing cotton form multiple reflections and attenuation, improving the sound insulation performance of the honeycomb wall panel. Furthermore, perforations are made inside the back panel, which, together with the second sound-absorbing cotton embedded in its internal grooves, can enhance the mid-to-high frequency sound absorption effect, further improving the sound insulation performance of the honeycomb wall panel.

[0005] To achieve the above objectives, a high sound insulation all-aluminum honeycomb wall panel is provided, including a back panel and an outer panel. The back panel and the outer panel are provided with a first protective layer and a second protective layer on the side of the back panel and the outer panel that are separated from each other. A honeycomb core is connected by an adhesive layer, and the honeycomb core is filled with a first sound-absorbing cotton.

[0006] The back panel has perforations to form a porous structure, and the back panel has an embedding groove filled with a second sound-absorbing cotton.

[0007] According to the aforementioned high sound insulation all-aluminum honeycomb wall panel, the first protective layer includes a base plate, and the base plate and the back plate are also connected by an adhesive layer.

[0008] According to the aforementioned high sound insulation all-aluminum honeycomb wall panel, the second protective layer includes a chromated layer disposed on the surface of the outer layer panel and a fluorocarbon paint layer disposed on the surface of the chromated layer.

[0009] According to the aforementioned high sound insulation all-aluminum honeycomb wall panel, the first protective layer further includes a polyester paint layer disposed on the back side of the base plate.

[0010] According to the aforementioned high sound insulation all-aluminum honeycomb wall panel, each of the multiple adjacent first sound-absorbing cotton tops is jointly and fixedly connected with a connecting strip, and the outer layer plate has a groove on the side near the connecting strip that is inserted into the connecting strip.

[0011] According to the aforementioned high sound insulation all-aluminum honeycomb wall panel, the first sound-absorbing cotton has a gradient density structure, with the density of the first sound-absorbing cotton increasing from the outside to the inside.

[0012] According to the aforementioned high sound insulation all-aluminum honeycomb wall panel, the first sound-absorbing cotton is melamine sound-absorbing cotton, and the second sound-absorbing cotton is sound-absorbing non-woven fabric.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, the honeycomb core is filled with a first sound-absorbing cotton, which creates multiple reflections and attenuation between the honeycomb core and the first sound-absorbing cotton, thus improving the sound insulation performance of the honeycomb wall panel. Furthermore, perforations are made inside the back panel, which, together with the second sound-absorbing cotton embedded in its internal grooves, enhance the mid-to-high frequency sound absorption effect, further improving the sound insulation performance of the honeycomb wall panel.

[0015] 2. Compared with existing technologies, by setting a base plate to protect the second sound-absorbing cotton, the polyester paint layer on the back of the base plate improves the corrosion resistance of the base plate; by setting a chromate layer and a fluorocarbon paint layer on the outer layer plate, the weather resistance and UV resistance of the outer layer plate are enhanced, thereby improving the corrosion resistance of the honeycomb wall panel in outdoor applications.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses a high-sound-insulating all-aluminum honeycomb wall panel, comprising a back panel 1 and an outer panel 3. A first protective layer and a second protective layer are respectively provided on the side of the back panel 1 and the outer panel 3 that are separated from each other. A honeycomb core 2 is connected by an adhesive layer 6. The back panel 1, outer panel 3, honeycomb core 2, and bottom panel 9 are all made of aluminum. The honeycomb core 2 is filled with a first sound-absorbing cotton 4. The back panel 1 has perforations 7 forming a porous structure. An embedding groove is formed inside the back panel 1, and the embedding groove is filled with a second sound-absorbing cotton 8. The second sound-absorbing cotton 8 is a sound-absorbing non-woven fabric. The material of the sound-absorbing non-woven fabric has many interconnected micropores. Sound waves passing through the non-woven fabric structure generate friction. This friction causes kinetic energy loss, thereby reducing the sound wave value.

[0025] The honeycomb structure of the honeycomb core 2 provides excellent sound and heat insulation, effectively reducing the intrusion of external noise and lowering the temperature difference between indoors and outdoors. Simultaneously, the honeycomb core 2 is filled with first sound-absorbing cotton 4, which creates multiple reflections and attenuation between the honeycomb core 2 and the first sound-absorbing cotton 4, improving the sound insulation performance of the honeycomb wall panel. Furthermore, perforations 7 are opened inside the back panel 1, which, together with the second sound-absorbing cotton 8 embedded in its internal grooves, enhance the mid-to-high frequency sound absorption effect, further improving the sound insulation performance of the honeycomb wall panel.

[0026] The first protective layer includes a base plate 9 and a polyester paint layer 10 on the back side of the base plate 9. The base plate 9 protects the second sound-absorbing cotton 8, and the polyester paint layer 10 improves the corrosion resistance of the base plate 9. The base plate 9 is bonded to the back plate 1 by an adhesive layer 6, and the base plate 9 and the back plate 1 are also connected by an adhesive layer 6. The second protective layer includes a chromate layer 11 on the surface of the outer layer plate 3 and a fluorocarbon paint layer 12 on the surface of the chromate layer 11, which enhances the weather resistance and UV resistance of the outer layer plate 3.

[0027] Each of the adjacent first sound-absorbing cotton 4 is fixedly connected to a connecting strip 5 at its top, facilitating the filling of the honeycomb core 2 inside the honeycomb core 2. The outer layer plate 3 has a groove on the side near the connecting strip 5 that mates with the connecting strip 5, ensuring the outer layer plate 3 fits snugly against the honeycomb core 2 and guaranteeing tight adhesion.

[0028] The first sound-absorbing cotton 4 is melamine sound-absorbing cotton. The first sound-absorbing cotton 4 has a gradient density structure, with the density increasing from the outside to the inside, in order to optimize the sound absorption performance of different frequency bands.

[0029] Working principle: The honeycomb structure of the honeycomb core 2 provides excellent sound and heat insulation, effectively reducing the intrusion of external noise and lowering the temperature difference between indoors and outdoors. Simultaneously, the honeycomb core 2 is filled with first sound-absorbing cotton 4, which, through multiple reflections and attenuation, enhances the sound insulation performance of the honeycomb wall panel. Furthermore, perforations 7 are opened inside the back panel 1, which, together with the second sound-absorbing cotton 8 embedded in its internal grooves, enhance the mid-to-high frequency sound absorption effect, further improving the sound insulation performance of the honeycomb wall panel.

[0030] By setting a base plate 9 to protect the second sound-absorbing cotton 8, the polyester paint layer 10 on the back side of the base plate 9 improves the corrosion resistance of the base plate 9; by setting a chromate layer 11 and a fluorocarbon paint layer 12 on the outer layer plate 3, the weather resistance and UV resistance of the outer layer plate 3 are enhanced, thereby improving the corrosion resistance of the honeycomb wall panel in outdoor applications.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
