Description

Technical Field

[0001] This utility model belongs to the field of wall panel technology, specifically a soundproof building decorative wall panel. Background Technology

[0002] Sound is a wave-like form of energy that requires a medium to propagate. When sound travels within the same medium, the greater the density of the medium, the faster the sound travels. Another form of sound propagation is cross-medium propagation. This involves sound traveling from one medium, passing through the interface between the two media, and entering another medium. In this case, the transfer of sound energy is essentially the transfer of vibration amplitude. With the acceleration of urbanization, building noise pollution has become a core issue affecting the living environment. Many residential complaints are related to defects in the sound insulation of walls.

[0003] Some existing building decorative panels use ordinary gypsum board or lightweight composite board with a single-layer structure, and their density is generally much lower than that of red bricks. This results in high sound wave penetration, allowing people to clearly hear neighbors' normal conversations. On the other hand, traditional decorative panels are directly fixed to the wall through a keel frame without sound insulation felt. When sound waves are conducted through solids, there is no elastic material to absorb vibration energy, making it easy for sound waves to penetrate and resulting in poor sound insulation.

[0004] Therefore, we propose a soundproof building decorative wall panel. Utility Model Content

[0005] The purpose of this utility model is to provide a soundproof building decorative wall panel in order to improve the sound insulation effect of the wall panel.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A soundproof building decorative wall panel includes a honeycomb panel layer, a light steel keel frame fixedly connected to the rear side of the honeycomb panel layer, a sound insulation felt fixedly connected to the side of the light steel keel frame away from the honeycomb panel layer, and a plurality of rectangular frame grooves provided inside the light steel keel frame, with a sound insulation layer fixedly connected to the inner sidewall of the rectangular frame groove.

[0008] The sound insulation layer includes a foam layer, one side of which is fixedly connected to the honeycomb panel layer, a centrifugal glass wool layer is fixedly connected to the side of the foam layer away from the honeycomb panel layer, a damping layer is fixedly connected to the side of the centrifugal glass wool layer away from the foam layer, and a rock wool board layer is fixedly connected to the side of the damping layer away from the centrifugal glass wool layer.

[0009] Furthermore, the side of the rock wool board layer away from the damping layer is fixedly connected to the outer surface of the sound insulation felt.

[0010] Furthermore, the damping layer is a butyl rubber damping layer.

[0011] Furthermore, the thickness of the honeycomb panel layer is 9mm, and the thickness of the sound insulation felt is 3mm.

[0012] Furthermore, the thickness of the foamed cotton layer is 15mm, the thickness of the centrifugal glass wool layer is 20mm, the thickness of the damping layer is 5mm, and the thickness of the rock wool board layer is 60mm.

[0013] Furthermore, the foam layer is a polyurethane foam layer.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, during installation, the sound insulation felt of the wall panel is attached to the wall surface to fix the light steel keel frame to the wall. When noise is generated indoors, the honeycomb units on the honeycomb panel force the sound waves to be reflected and scattered multiple times, causing the energy to continuously attenuate. Noise propagates in the air through vibration. When the vibration encounters the porous foam layer, the vibration is transmitted into the interior of the foam layer. It is hindered by friction with the complex internal pores, and the energy is attenuated, thereby weakening the noise. At the same time, the interwoven fibers inside the centrifugal glass wool layer form micropores. After the sound waves enter, the air molecules rub against each other in the narrow channels, converting the sound energy into heat energy. The sound wave vibration causes the air to compress and heat up. The heat is quickly dissipated through the fibers, resulting in a good sound absorption effect. The combination of the above structures can improve the sound insulation effect of the wall panel.

[0016] 2. In this invention, the damping layer is polymerized from isobutylene and a small amount of isoprene. Its molecular chains have densely distributed methyl groups, forming a tight steric hindrance effect. When sound waves propagate within the material, the energy is blocked by the rigid structure of the molecular chains, causing a sharp drop in airborne sound transmission efficiency. Furthermore, the long molecular chains of the damping layer are entangled, and when sound waves induce vibration, the long chains within the damping layer entangle and rub against each other, converting mechanical energy into heat energy for dissipation. The rock wool board layer is formed by high-temperature rotation and stretching of molten rock fibers, possessing an open pore structure. This open pore structure can effectively absorb the energy of sound waves. Simultaneously, the high-density polymer material of the sound insulation felt adhered to the wall absorbs vibration energy, dissipating vibration energy through molecular friction to achieve sound insulation. The combination of these structures further enhances the sound insulation effect of the wall panel. Attached Figure Description

The honeycomb panel layer 1 has a thickness of 9mm, and the sound insulation felt 4 has a thickness of 3mm. The light steel keel frame 2 has several rectangular slots 21 inside, and a sound insulation layer 3 is fixedly connected to the inner wall of the rectangular slots 21. The sound insulation layer 3 includes a polyurethane foam layer 31, one side of which is fixedly connected to the honeycomb panel layer 1, and a centrifugal glass wool layer 32 fixedly connected to the side of the foam layer 31 away from the honeycomb panel layer 1. The foam layer 31 has a thickness of 15mm, and the centrifugal glass wool layer 32 has a thickness of 20mm. Specifically, during installation, the honeycomb panel layer 1 is... The sound insulation felt 4 of the wall panel is installed against the wall surface to fix the light steel keel frame 2 to the wall surface. When noise is generated indoors, the honeycomb units on the honeycomb panel layer 1 force the sound waves to be reflected and scattered multiple times, causing the energy to continuously attenuate. Noise propagates in the air in the form of vibration. When the vibration encounters the porous foam layer 31, the vibration is transmitted into the interior of the foam layer 31. It is hindered by friction with the complex internal pores, and the energy is attenuated, thereby weakening the noise. At the same time, the internal fibers of the centrifugal glass wool layer 32 interweave to form micropores. After the sound waves enter, the air molecules rub against each other in the narrow channels, converting the sound energy into heat energy. The sound wave vibration causes the air to compress and heat up. The heat is quickly dissipated by the fibers, resulting in a good sound absorption effect. The combination of the above structures can improve the sound insulation effect of the wall panel.

[0023] Reference Figures 1-3A damping layer 33 is fixedly connected to the side of the centrifugal glass wool layer 32 away from the foam layer 31. The damping layer 33 is a butyl rubber damping layer. A rock wool board layer 34 is fixedly connected to the side of the damping layer 33 away from the centrifugal glass wool layer 32. The thickness of the damping layer 33 is 5 mm, and the thickness of the rock wool board layer 34 is 60 mm. The side of the rock wool board layer 34 away from the damping layer 33 is fixedly connected to the outer surface of the sound insulation felt 4. Specifically, the damping layer 33 is polymerized from isobutylene and a small amount of isoprene. The methyl groups in its molecular chain are densely distributed, forming a tight steric hindrance effect. When sound waves propagate inside the material, the energy is... The rigid structure of the molecular chains obstructs sound transmission, drastically reducing airborne sound transmission efficiency. Furthermore, the long molecular chains of the damping layer 33 become entangled, and when sound waves induce vibrations, the entangled and rubbing chains within the damping layer 33 convert mechanical energy into heat energy, which is then dissipated. Meanwhile, the rock wool board layer 34, formed from molten rock fibers through high-temperature rotation and stretching, possesses an open-pore structure that effectively absorbs sound wave energy. Simultaneously, the high-density polymer material of the sound insulation felt 4, adhered to the wall, absorbs vibration energy, dissipating it through molecular friction to achieve sound insulation. The combination of these structures further enhances the sound insulation effect of the wall panel.

[0024] The implementation principle of an embodiment of a soundproof building decorative wall panel in this application is as follows:

[0025] During installation, the sound insulation felt 4 of the wall panel is attached to the wall surface to fix the light steel keel frame 2 to the wall surface. When noise is generated indoors, the honeycomb units on the honeycomb panel layer 1 force the sound waves to be reflected and scattered multiple times, causing the energy to continuously attenuate. Noise propagates in the air in the form of vibration. When the vibration encounters the porous foam layer 31, the vibration is transmitted into the interior of the foam layer 31. It is hindered by friction with the complex internal pores, and the energy is attenuated, thereby weakening the noise. At the same time, the interwoven fibers inside the centrifugal glass wool layer 32 form micropores. After the sound waves enter, the air molecules rub against each other in the narrow channels, converting the sound energy into heat energy. The sound wave vibration causes the air to compress and heat up. The heat is quickly dissipated by the fibers, resulting in a good sound absorption effect. The combination of the above structures can improve the sound insulation effect of the wall panel.

[0026] On the other hand, the damping layer 33 is polymerized from isobutylene and a small amount of isoprene. The methyl groups in its molecular chain are densely distributed, forming a tight steric hindrance effect. When sound waves propagate inside the material, the energy is blocked by the rigid structure of the molecular chain, and the air transmission efficiency drops sharply. Moreover, the long molecular chains of the damping layer 33 are entangled. When the sound waves cause vibration, the long chains in the damping layer 33 entangle and rub against each other, converting mechanical energy into heat energy and dissipating it. The rock wool board layer 34 is formed by high-temperature rotation and stretching of molten rock fibers and has an open pore structure. This open pore structure can effectively absorb the energy of sound waves. At the same time, the high-density polymer material of the sound insulation felt 4 attached to the wall can absorb vibration energy and dissipate vibration energy through molecular friction to achieve sound insulation. The combination of the above structures can further improve the sound insulation effect of the wall panel.
