Technical Field

[0001] This utility model relates to the field of sound-absorbing sponge technology, specifically to a sound-absorbing and noise-reducing porous polymer sponge. Background Technology

[0002] Currently, noise pollution is one of the three major public hazards threatening human society. Sound-absorbing sponges, due to their excellent sound absorption and insulation effects, are widely used in fields such as building decoration, transportation vehicles, ships, aerospace, electromechanical equipment, and industrial sound absorption and insulation.

[0003] However, the existing sound-absorbing sponges have a very simple sound-absorbing structure, and the sound-absorbing capacity of the wave-shaped sound-absorbing grooves is limited, which makes it impossible to further improve the sound absorption effect of the sound-absorbing sponges. Therefore, traditional sound-absorbing sponges can no longer meet people's growing demand for noise reduction. Utility Model Content

[0004] This invention provides a sound-absorbing and noise-reducing porous polymer sponge, which solves the problem that the sound-absorbing structure of the sound-absorbing sponge in the background art is very simple and the sound absorption capacity is limited.

[0006] A sound insulation layer is fixedly installed on the upper end of the upper polymer sponge, an antibacterial layer is fixedly installed on the upper end of the sound insulation layer, and a flame-retardant sponge layer is fixedly installed on the upper end of the antibacterial layer. Air holes are opened on the side walls of the flame-retardant sponge layer, the antibacterial layer, the sound insulation layer, and the upper polymer sponge.

[0007] Furthermore, several sound-absorbing strips are uniformly fixedly installed on the outer end of the sound-absorbing cotton, and sound-absorbing grooves are opened on the sound-absorbing cotton between two adjacent sound-absorbing strips. The sound-absorbing grooves and sound-absorbing strips are all triangular prisms.

[0008] Furthermore, a plurality of sound-absorbing holes are evenly provided on the side wall of the sound-absorbing strip, and a plurality of sound-absorbing holes are evenly provided on the inner wall of the sound-absorbing groove.

[0011] Furthermore, an adhesive layer is provided at the lower end of the second sound insulation layer.

[0012] Furthermore, an isolation layer is provided at the lower end of the adhesive layer.

[0013] This invention provides a sound-absorbing and noise-reducing porous polymer sponge. It has the following beneficial effects:

[0014] This invention allows the polymer sponge to be adhered to the wall by peeling off the isolation layer from the adhesive layer.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a sound-absorbing and noise-reducing porous polymer sponge, comprising: a lower polymer sponge body 1 and an upper polymer sponge body 2. Each of the adjacent ends of the lower polymer sponge body 1 and the upper polymer sponge body 2 has a sound-absorbing cavity 3. Sound-absorbing cotton 4 is fixedly adhered to the inner wall of each sound-absorbing cavity 3. Several sound-absorbing strips 5 are evenly fixedly installed on the outer end of the sound-absorbing cotton 4. Sound-absorbing grooves 7 are formed on the sound-absorbing cotton 4 between adjacent sound-absorbing strips 5. Both the sound-absorbing grooves 7 and the sound-absorbing strips 5 are triangular prisms. The side walls of the sound-absorbing strips 5 are... A number of sound-absorbing holes 6 are evenly distributed on the inner wall of the sound-absorbing groove 7. A number of sound-absorbing holes 8 are evenly distributed on the inner wall of the upper polymer sponge 2. An air hole 13 is provided on the side wall of the upper polymer sponge 2. The air hole 13 passes through the sound-absorbing cavity 3 and penetrates the side wall of the sound-absorbing cotton 4, allowing sound to enter the sound-absorbing cavity 3 through the air hole 13 and then be absorbed by the sound-absorbing cotton 4, the sound-absorbing strip 5, and the sound-absorbing groove 7, thereby increasing the sound absorption effect of the polymer sponge. At the same time, the sound-absorbing holes 6 on the sound-absorbing strip 5 and the sound-absorbing holes 8 in the sound-absorbing groove 7 further increase the sound absorption effect of the sound-absorbing strip 5 and the sound-absorbing groove 7.

[0023] Specifically, both the sound-absorbing cotton 4 and the sound-absorbing strip 5 are made of polyester sound-absorbing cotton with excellent sound absorption performance. Polyester sound-absorbing cotton is composed of 100% polyester fiber through high-tech hot pressing and formed into a cocoon shape. It not only has good sound absorption performance, but is also soft, highly elastic, and has fire-resistant properties.

[0024] The lower polymer sponge 1 and the upper polymer sponge 2 are fixed together by an adhesive layer 9. The sound-absorbing cavities 3 on the lower polymer sponge 1 and the upper polymer sponge 2 are connected to form a large cavity. The air inside the cavity has a sound insulation effect, which increases the sound insulation effect of the polymer sponge.

[0025] A sound insulation layer 10 is fixedly installed on the upper end of the upper polymer sponge body 2. The sound insulation layer 10 is made of high-density sponge with high resilience and good support. An antibacterial layer 11 is fixedly installed on the upper end of the sound insulation layer 10. The antibacterial layer 11 is made of bamboo fiber blended with cotton and viscose, all of which have natural antibacterial properties. A flame-retardant sponge layer 12 is fixedly installed on the upper end of the antibacterial layer 11. The flame-retardant sponge enables the polymer sponge to have fire-retardant and flame-retardant properties. Air holes 13 are opened on the side walls of the flame-retardant sponge layer 12, the antibacterial layer 11, the sound insulation layer 10, and the upper polymer sponge body 2. The air holes 13 penetrate the side wall of the sound-absorbing cotton 4. Sound enters the sound insulation layer 10, the polymer sponge, the sound-absorbing cavity 3, the sound-absorbing cotton 4, and the sound-absorbing strip 5 through the air holes 13, absorbing the sound in batches and gradually improving the absorption effect of the polymer sponge. At the same time, the air holes 13 also make the polymer sponge breathable.

[0026] A second sound insulation layer 14 is fixedly installed at the lower end of the lower polymer sponge 1. The second sound insulation layer 14 is made of the same material as the first sound insulation layer 10, which further improves the sound absorption effect of the polymer sponge.

[0027] Specifically, sound enters the sound insulation layer 10, polymer sponge, sound absorption cavity 3, sound absorption cotton 4 and sound absorption strip 5 through the pores 13, absorbing the sound in batches and gradually improving the absorption effect of the polymer sponge. At the same time, the pores 13 also make the polymer sponge breathable.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, the adhesive layer 9 is orifice-shaped and located at the outer end of the sound-absorbing cavity 3. More specifically, after the sound-absorbing cotton 4 is installed in the sound-absorbing cavity 3, the upper polymer sponge 2 and the lower polymer sponge 1 are bonded together by the adhesive layer 9, which facilitates the installation of the sound-absorbing cotton 4.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, an adhesive layer 15 is provided at the lower end of the sound insulation layer 14, and an isolation layer 16 is provided at the lower end of the adhesive layer 15. More specifically, the isolation layer 16 is a plastic film. The isolation layer 16 serves to protect the adhesive layer 15. When it is necessary to install the polymer sponge, the isolation layer 16 can be peeled off from the adhesive layer 15, and the polymer sponge can be adhered to the wall through the adhesive layer 15, which is convenient for installation.

[0030] When in use: peel the isolation layer 16 off the adhesive layer 15, and the polymer sponge can be bonded to the wall through the adhesive layer 15. Noise enters the sound insulation layer 10, polymer sponge, sound absorption cavity 3, sound absorption cotton 4 and sound absorption strip 5 through the air hole 13, and the sound is absorbed in batches and gradually, improving the absorption effect of the polymer sponge.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
