Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically to a sound-insulating composite board. Background Technology

[0002] Composite panels are multifunctional boards made of two or more materials with different properties, bonded and pressed together. The core advantage of composite panels lies in the complementary properties of each layer of materials. For example, a high-strength base material can be used to improve the structural load-bearing capacity, achieving comprehensive characteristics that a single material cannot possess. The design concept of this material stems from the need to optimize material performance. When the strength, weather resistance, functionality, and other indicators of a single material cannot meet the requirements of a specific scenario, the advantages of different materials are superimposed through the composite process to form a "performance synergy." For example, a metal base layer provides structural strength, thermal insulation is achieved by combining it with thermal insulation cotton, and a fireproof coating is applied to improve safety. This allows the board to simultaneously possess multiple properties such as load-bearing, thermal insulation, and fire resistance, meeting the comprehensive needs of building, industrial, and other scenarios. However, in the use of existing composite panels, traditional composite panels often use a single-layer or simple double-layer structure, lacking the effect of absorbing and blocking sound waves, resulting in poor sound insulation and affecting the use of composite panels. Utility Model Content

[0003] The purpose of this utility model is to provide a sound-insulating composite board to solve the problem mentioned in the background art of lacking the effect of absorbing and blocking sound waves, resulting in poor sound insulation effect of the composite board and affecting its use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sound-insulating composite board, comprising a gypsum board layer, wherein a barrier layer is installed on one side surface of the gypsum board layer, and a reinforcing layer is connected to the surface of the gypsum board layer.

[0005] A rock wool layer is installed at the end of the reinforcement layer, and damping rubber sheets are installed at equal intervals on the surface of the rock wool layer. A gypsum board is installed on the other side of the damping rubber sheets.

[0006] Preferably, the barrier layer and the reinforcing layer are symmetrically installed on the surface of the first gypsum board layer.

[0007] Using the above technical solution, the barrier layer blocks sound from one side of the gypsum board layer while absorbing sound at the same time.

[0008] Preferably, the reinforcing layer is an interlaced plate-like structure, and the cross-section of the reinforcing layer is set as an X-shaped structure, and the reinforcing layer is installed on top of the first gypsum board layer.

[0012] Preferably, a cavity is provided between the rock wool layer and the second gypsum board, and the cavity between the rock wool layer and the second gypsum board is an air layer.

[0013] By adopting the above technical solution, the sound waves transmitted to this location are absorbed by the rock wool layer, thus providing sound insulation for the composite board.

[0014] Preferably, the damping rubber sheet is disposed inside the air layer between the rock wool layer and the gypsum board.

[0015] By adopting the above technical solution, when sound waves enter the air layer between the rock wool layer and the gypsum board, the elasticity of the air inside the air layer can be used to buffer the sound waves.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a sound-insulating composite board, comprising a gypsum board layer 10, a barrier layer 20, a reinforcing layer 30, a rock wool layer 40, a damping rubber sheet 50, and a second gypsum board 60;

[0028] This composite board can improve its sound insulation effect. The specific implementation method is as follows:

[0029] A barrier layer 20 is installed on one side of the surface of gypsum board layer 10, and a reinforcing layer 30 is connected to the surface of gypsum board layer 10. A rock wool layer 40 is installed at the end of the reinforcing layer 30, and damping rubber sheets 50 are installed at equal intervals on the surface of the rock wool layer 40. A second gypsum board 60 is installed on the other side of the damping rubber sheets 50. The barrier layer 20 and the reinforcing layer 30 are symmetrically installed on the surface of gypsum board layer 10. The reinforcing layer 30 has an interlaced plate structure, and the cross-section of the reinforcing layer 30 is set as an X-shaped structure. The reinforcing layer 30 is installed on the surface of gypsum board layer 10. At the top, the damping rubber sheet 50 is set in a square structure, and the damping rubber sheet 50 is evenly arranged between the rock wool layer 40 and the second gypsum board 60. A cavity is set between the rock wool layer 40 and the second gypsum board 60, and the cavity between the rock wool layer 40 and the second gypsum board 60 is an air layer. The damping rubber sheet 50 is set inside the air layer between the rock wool layer 40 and the second gypsum board 60. The second gypsum board 60 is fixed on top of the damping rubber sheet 50, and the reinforcement layer 30, the rock wool layer 40, the damping rubber sheet 50 are between the first gypsum board layer 10 and the second gypsum board 60.

[0030] Damping coating is sprayed onto the surface of gypsum board layer 10 using a spraying device, forming a barrier layer 20 on the surface of gypsum board layer 10. Reinforcing layer 30 is fixed to the top surface of gypsum board layer 10 using a hot pressing device. Rock wool layer 40 is then fixed to the surface of reinforcing layer 30 using a hot pressing device. Damping rubber sheet 50 is then adhered to the surface of rock wool layer 40, ensuring that the damping rubber sheet 50 is evenly and equidistantly adhered to the surface of rock wool layer 40. Finally, gypsum board layer 60 is fixed to the surface of damping rubber sheet 50 using a hot pressing device.

[0031] When the sound wave reaches the surface of the barrier layer 20, the viscoelastic material of the damping coating of the barrier layer 20 can absorb the energy of the mid-to-high frequency sound wave. Then, when the sound wave penetrates the barrier layer 20 and reaches the gypsum board layer 10, most of the sound wave is reflected back to the outside. The remaining sound wave is transmitted to the inner layer in a small amount through the pores of the board, so that the sound wave is transmitted to the surface of the rock wool layer 40. The rock wool layer 40 absorbs the sound wave, and then the sound wave enters the cavity between the rock wool layer 40 and the gypsum board 60. At the same time, the air buffers the sound wave, and the damping rubber sheet 50 dampens the sound wave. The sound wave is transmitted to the gypsum board 60, so that the gypsum board 60 absorbs and reflects the sound wave, preventing the sound wave from being transmitted to the other side of the composite board.

[0032] When sound waves are transmitted to the surface of gypsum board 260, gypsum board 260 can reflect the sound waves. A small amount of sound waves enter the cavity between rock wool layer 40 and gypsum board 260 through gypsum board 260. The elasticity of the air inside the cavity can buffer the propagation of sound waves. When the sound waves excite the rock wool layer 40 of gypsum board 2 to vibrate, the damping rubber sheet 50 consumes the vibration energy through the movement of molecular chains, avoiding the resonance of the board and amplification of noise. At the same time, when the sound waves enter the surface of rock wool layer 40 through the cavity, rock wool layer 40 absorbs the sound waves. Rock wool layer 40 transmits the sound waves through reinforcing layer 30 to gypsum board layer 10. Gypsum board layer 10 reflects the sound waves and transmits them to barrier layer 20, where the barrier layer 20 absorbs the sound waves.

[0033] Working principle: When using this sound-insulating composite board, the rock wool layer 40, damping rubber sheet 50 and gypsum board 60 are set, which can improve its sound insulation effect and increase its overall practicality.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
