[0004] Although the above-mentioned existing technology can achieve sound insulation for glass fiber boards, in actual use, on the one hand, the sound insulation effect of glass fiber boards is not good enough. When facing noises in different frequency bands, the sound insulation effects of the same layer of sound insulation boards are different, resulting in noises in some frequency bands passing through the glass fiber boards, thereby affecting the sound insulation effect. On the other hand, it is difficult to protect the surface of glass fiber boards. Glass fiber boards will inevitably be damaged during use. When the surface of the glass fiber boards is damaged, the sound insulation layer will be affected, thereby shortening the service life of the glass fiber boards. Therefore, it does not meet the existing needs. In this regard, we propose a sound insulation glass fiber board. Utility Model Content

[0005] The utility model aims to provide a sound-insulating glass fiber board to solve the problems that the sound-insulating effect of the glass fiber board proposed in the above background technology is not good enough and the surface of the glass fiber board is difficult to protect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sound insulation glass fiber board, including a glass fiber board body; and also including:

[0007] A first sound insulation layer is arranged on one side of the glass fiber board body, and the first sound insulation layer is connected to the glass fiber board body by glue;

[0008] The second sound insulation layer is arranged on the other side of the glass fiber board body. Two second sound insulation layers are arranged, and the second sound insulation layers are connected to the glass fiber board body by glue.

[0009] Preferably, a sound absorbing layer is disposed on one side inside the first sound insulation layer and the second sound insulation layer, and an insulating layer is disposed on the other side inside the first sound insulation layer and the second sound insulation layer.

[0010] Preferably, a vacuum cavity is provided between the sound absorbing layer and the insulating layer, and the vacuum cavity is connected to the sound absorbing layer and the insulating layer respectively by glue.

[0011] Preferably, a functional layer is provided inside the glass fiber board body close to the first sound insulation layer and the second sound insulation layer, and the functional layer is connected to the glass fiber board body by hot pressing.

[0012] Preferably, a flame retardant layer is provided inside the functional layer close to the outer side of the glass fiber board body.

[0013] Preferably, a heat insulating layer is provided inside the functional layer located on one side of the flame retardant layer, and the heat insulating layer and the flame retardant layer are connected by hot pressing.

[0014] Preferably, a buffer layer is provided inside the functional layer located on one side of the thermal insulation layer, and the buffer layer and the thermal insulation layer are connected by hot pressing.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can block noises of different frequency bands through the first sound insulation layer and the second sound insulation layer. When noise is generated, the noise first passes through the first sound insulation layer, and the low-frequency noise is isolated by the first sound insulation layer. At this time, part of the high-frequency noise continues to propagate inside the glass fiber board body until the high-frequency noise contacts the second sound insulation layer, and the high-frequency noise is eliminated by the second sound insulation layer, thereby improving the sound insulation effect of the glass fiber board body.

[0017] 2. The utility model can protect the appearance of the glass fiber board by providing a functional layer. When a fire occurs, the fire source is first contacted with the functional layer of the glass fiber board body, and the fire source is isolated by the outermost flame retardant layer of the functional layer, thereby preventing the fire from spreading. At this time, the heat in the fire source can be isolated by the heat insulation layer, and the thermal insulation effect of the glass fiber board body can also be increased. The buffer layer is provided to protect the glass fiber board body when a collision occurs. When the glass fiber board body collides, the impact force is transmitted to the buffer layer through the surface layer of the glass fiber board body. At this time, the buffer layer deforms to absorb and relieve the impact. When the impact disappears, the buffer layer is reset, and energy is released by the reset of the buffer layer. The service life of the glass fiber board is extended through the functional layer.

[0018] 3. The utility model can improve the sound insulation effect of the first sound insulation layer and the second sound insulation layer through the sound absorption layer and the vacuum cavity. When the glass fiber board body is installed, when the noise is transmitted to the first sound insulation layer and the second sound insulation layer, the noise first passes through the sound absorption layer, and the sound waves are absorbed by the sound absorption layer. When passing through the vacuum cavity, the propagation of the noise is reduced by the vacuum environment, and finally the noise is isolated by the isolation layer. The sound insulation effect of the first sound insulation layer and the second sound insulation layer is improved through multiple sound insulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] During use, when noise is generated, the noise first passes through the first sound insulation layer 2, and the low-frequency noise is isolated by the first sound insulation layer 2. At this time, part of the high-frequency noise continues to propagate inside the glass fiber board body 1 until the high-frequency noise contacts the second sound insulation layer 3, and the high-frequency noise is eliminated by the second sound insulation layer 3, thereby improving the sound insulation effect of the glass fiber board body 1.

[0032] See also Figure 2and Figure 3 A flame retardant layer 401 is arranged inside the functional layer 4 close to the outer side of the glass fiber board body 1 , wherein the flame retardant layer 401 is filled with extruded polystyrene, so that the outer side of the glass fiber board body 1 can be protected by the flame retardant layer 401 .

[0033] See also Figure 2 and Figure 3 A heat insulating layer 402 is arranged inside the functional layer 4 located on one side of the flame retardant layer 401, and the heat insulating layer 402 is connected to the flame retardant layer 401 by hot pressing, wherein the heat insulating layer 402 is filled with ceramic fibers, so that the heat insulating layer 402 can be used to isolate heat while increasing the thermal insulation effect of the glass fiber board body 1.

When the impact disappears, the buffer layer 403 is reset, and energy is released through the reset of the buffer layer 403, and the service life of the glass fiber board body 1 is extended through the functional layer 4. When the glass fiber board body 1 is installed, when the noise is transmitted to the first sound insulation layer 2 and the second sound insulation layer 3, the noise first passes through the sound absorbing layer 5, and the sound waves are absorbed by the sound absorbing layer 5, and then passes through the vacuum cavity 6, the propagation of the noise is reduced by the vacuum environment, and finally the noise is isolated by the insulating layer 7, and the sound insulation effect of the first sound insulation layer 2 and the second sound insulation layer 3 is improved through multiple sound insulation.
