Description

Technical Field

[0001] This utility model relates to the field of stone composite panel technology, specifically a double-layer sound-absorbing stone composite panel. Background Technology

[0002] Ultra-thin stone composite panels are made by bonding two or more different types of panels together with adhesives. The surface material is natural stone, and the substrate is ceramic tile, stone, glass, or aluminum honeycomb, etc.

[0003] Existing patent: CN202969817U, discloses an aluminum honeycomb stone composite panel, including a stone slab, an aluminum honeycomb, and a weather-resistant strong adhesive film, wherein the stone slab and the aluminum honeycomb are bonded to both sides of the strong adhesive film.

[0004] The aforementioned patents or existing stone composite panels have the following problems:

[0005] The sound insulation structure of existing stone composite panels is relatively simple. Most of them are made by filling the honeycomb panels with sound-insulating materials to achieve the sound insulation effect. However, the sound insulation effect of existing stone composite panels with sound-insulating materials is relatively average. Utility Model Content

[0006] The purpose of this utility model is to provide a double-layer sound-absorbing stone composite panel to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer sound-absorbing stone composite panel, comprising a panel layer, a stone panel disposed on the panel layer, a honeycomb panel connected to the panel layer, a base plate layer fixed to the surface of the honeycomb panel, a sound insulation structure disposed on the surface of the honeycomb panel, the sound insulation structure comprising a metal plate, a metal plate fixed to the surface of the honeycomb panel, a keel frame disposed on the metal plate, a sound-absorbing layer disposed in the keel frame, a fiberboard disposed on the keel frame, an adhesive layer disposed on the surface of the fiberboard, and a second sound insulation structure disposed on the surface of the honeycomb panel.

[0008] Preferably, the surface of the keel frame is provided with a gypsum layer, and the keel frame is connected and fixed to the fiberboard and metal plate through the gypsum layer.

[0009] Preferably, the sound-absorbing layer fills the cavity inside the keel frame.

[0010] Preferably, the structure of the second sound insulation structure is the same as that of the sound insulation structure.

[0011] Preferably, the honeycomb panel is located between the second sound insulation structure and the sound insulation structure.

[0012] Preferably, the keel frame in the second sound insulation structure is filled with sound-absorbing cotton.

[0013] Preferably, the bottom of the second sound insulation structure is provided with a waterproof and impermeable surface layer.

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

[0015] The honeycomb panel is located between the second sound insulation structure and the sound insulation structure, which is located between the base layer and the board layer. This achieves double-layer sound insulation in the stone composite panel, thus improving its sound insulation. The keel frame is filled with a sound-absorbing layer made of rock wool. The sound-absorbing layer absorbs sound waves and can absorb indoor sound, effectively preventing indoor sound from spreading outwards. After the sound-absorbing layer is treated, the sound waves are further treated by sound-absorbing cotton, thereby improving the sound insulation effect. The sound-absorbing cotton is made of glass wool. Glass wool is more porous than rock wool and has a faster sound wave attenuation ability, resulting in better sound absorption and effectively preventing external sound from spreading into the room. The stone composite panel with a double-layer sound insulation structure has the beneficial effect of high sound insulation. Attached Figure Description

Detailed Implementation

[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] Please see Figure 1 and Figure 2 This utility model provides a double-layer sound-absorbing stone composite panel, including a panel 1, a stone panel 2 disposed on the panel 1, a honeycomb panel 3 connected to the panel 1, a bottom panel 4 fixed to the surface of the honeycomb panel 3, and a sound insulation structure 5 disposed on the surface of the honeycomb panel 3.

[0022] Please see Figure 2 and Figure 3This utility model provides a double-layer sound-absorbing stone composite panel. The sound insulation structure 5 includes a metal plate 51. The metal plate 51 is welded to the surface of the honeycomb panel 3. The metal plate 51 can rigidly connect to the sound insulation structure 5, so that the sound insulation structure 5 is firmly fixed to the surface of the honeycomb panel 3, avoiding cracking. Moreover, the metal plate 51 also reflects some sound waves, which has a certain sound insulation effect. A keel frame 52 is bonded to the metal plate 51 through a gypsum layer 57. The gypsum layer 57 contains 60% adhesive. The gypsum layer 57 acts as an adhesive layer, which can effectively fill the gap between the keel frame 52 and the metal plate 51 to prevent sound leakage. The keel frame 52 is filled with a sound-absorbing layer 53. The sound-absorbing layer 53 is made of rock wool. The sound-absorbing layer 53 absorbs sound waves to achieve the function of sound absorption and sound insulation. Moreover, the sound-absorbing layer 53 is filled in the keel frame 52, which can prevent sound waves from reflecting in the cavity of the keel frame 52. A fiberboard 54 is bonded to the surface of the keel frame 52 through a gypsum layer 57. The fiberboard 54 reflects some sound waves, improving the sound insulation effect. An adhesive layer 55 is provided on the surface of the fiberboard 54, which is used to connect and fix the board layer 1 to the sound insulation structure 5. A second sound insulation structure 56 is provided on the surface of the honeycomb panel 3. The structure of the second sound insulation structure 56 is the same as that of the sound insulation structure 5. The honeycomb panel 3 is located between the structure of the second sound insulation structure 56 and the sound insulation structure 5 to achieve a double-layer sound absorption effect. The keel frame in the second sound insulation structure 56 is filled with sound-absorbing cotton 58. The sound-absorbing cotton 58 is made of glass wool. The interior of glass wool is more fluffy than rock wool, and its sound wave dissipation ability is faster, resulting in better sound absorption. A waterproof and impermeable surface layer 59 is provided at the bottom of the second sound insulation structure 56 to prevent water vapor and moisture from entering the interior of the sound insulation structure 5, thereby improving the service life of the sound insulation structure 5.

[0023] Specifically, the honeycomb panel 3 is located between the second sound insulation structure 56 and the sound insulation structure 5, while the sound insulation structure 5 is located between the bottom layer 4 and the board layer 1. This achieves double-layer sound insulation in the stone composite panel, thereby improving the sound insulation structure of the stone composite panel. The keel frame 52 is filled with a sound-absorbing layer 53, which is made of rock wool. The sound-absorbing layer 53 absorbs sound waves and can absorb indoor sound, effectively preventing indoor sound from spreading outward. After being treated by the sound-absorbing layer 53, the sound waves are further treated by the sound-absorbing cotton 58, thereby improving the sound insulation effect. The sound-absorbing cotton 58 is made of glass wool. The interior of glass wool is more fluffy than rock wool, and its ability to lose sound waves is faster, resulting in better sound absorption. It effectively prevents external sound from spreading into the room. The stone composite panel with a double-layer sound insulation structure has the beneficial effect of high sound insulation effect.
