This application relates to the technical field of a building material, especially a sound insulation board.

With the changes in economic structure, social structure, and spatial structure, the population has begun to concentrate on cities. Due to the increase in population, buildings began to develop towards tall buildings. Whether it is a commercial building used for office, or an apartment or community building used for residence, the population that it houses has gradually increased. The increase in population means that the noise generated by people will also increase. Not only that, even in Toutian houses, due to people's requirements for the quality of life and the importance of personal privacy, soundproof and shockproof walls have become an important issue.

In addition, in a densely populated situation, in order to effectively reduce the occurrence of disasters, the fireproof properties of building materials are gradually being valued. Under normal circumstances, the construction personnel need to install the sound insulation material on the wall first. Then, the construction personnel set the flame-resistant fireproof material on the sound insulation material. In this way, the wall can block the sound with the sound insulation material and reduce the flame propagation speed with the fireproof material. However, installing sound insulation materials and fireproof materials on the walls in order not only consumes manpower but also takes a lot of time.

Please refer to FIG. 1 and FIG. 2, which are respectively a cross-sectional view and a perspective view of a sound insulation board according to an embodiment of the present application. As shown in the figure, the sound insulation board 1A includes a sound insulation board main body 10 and a locking assembly 11. The sound insulation board main body 10 includes a first sub-layer 100 and a second sub-layer 101. The locking component 11 is arranged on the second sub-layer 101.

The first sub-layer 100 is used for sound insulation. Therefore, the first sublayer 100 contains a porous material. Porous materials refer to materials that contain many pores. The large number of two-phase interfaces formed by the multiple pores can hinder the transmission of sound and/or heat energy (for example, be absorbed or diverged irregularly). In this way, the sound insulation effect and heat insulation effect of the sound insulation board can be further improved. For example, the porous material can be styrofoam, organic fiber material, inorganic fiber material, foam, glass wool, rock wool, mineral wool, urea formaldehyde resin (urea formaldehyde resin) or polyurethane (polyurethane, PUR). One, but not limited to this.

In some embodiments, the first sub-layer 100 may also include a high damping material. The high damping material can increase the damping coefficient of the first sub-layer 100, so that the first sub-layer 100 has over-damping characteristics, that is, when the first sub-layer 100 is subjected to a force, no obvious oscillation or even vibration is produced. In this way, the first sub-layer 100 can absorb low-frequency vibrations transmitted in the building frame (for example, compressor vibration of air-conditioning, low-frequency vibration of audio-visual equipment, or building resonance caused by vehicle operation, etc.). Specifically, the high damping material may be a polymer damping material, a ceramic damping material, a piezoelectric damping material, or an electrorheological fluid material, or any combination thereof. Taking the polymer damping material as an example, it can include polyacrylate, polyurethane, epoxy resins, isobutylene isoprene rubber (IIR), nitrile butadiene rubber (NBR), or Any combination of it. However, the above-mentioned materials are only examples, and any materials recognized by a person with ordinary knowledge in the relevant technical field can be used in this application.

The second sublayer 101 is disposed on the first sublayer 100, and the smoke coefficient per unit area of the second sublayer 101 is lower than that of the first sublayer 100. The smoke coefficient is used to measure the amount of smoke emitted by the material when it is burned. More specifically, the smoke coefficient can be known from Formula 1. Formula 1: C _A =240*log ₁₀ (I ₀ / I)

Wherein, C _A is a coefficient fuming, I ₀ is the intensity度heating (Lux) when the start of the test, I is the light intensity度lowest value (Lux) of the heating test.

As mentioned above, when a material is burned, the elements in the material (for example, carbon, nitrogen, sulfur, oxygen and other elements) will combine with each other and produce new solid particles or liquid molecules. Solid particles or liquid molecules suspended in the air can hinder the travel of light (for example, cause light reflection, scattering, or refraction). Therefore, based on the penetration of light (the intensity of light after penetration will decrease with the concentration of smoke), it can be used to determine whether the material is easy to burn and a large number of solid particles or liquid molecules will be generated after combustion. In other words, the lower the smoke coefficient, the less flammable the material, or the less toxic substances are released from combustion.

Therefore, in some embodiments, the second sub-layer 101 may include a flame-resistant material. For example, when the smoke coefficient per unit area of the second sub-layer 101 is lower than 120, it means that the flame-resistant material in the second sub-layer 101 complies with the third-class flame-resistant material in the building regulations. For example, the second sub-layer 101 may include flame-resistant plywood, flame-resistant fiberboard, flame-resistant plastic board, gypsum board, or any combination thereof, or flame-resistant grade 3 materials recognized by those with ordinary knowledge in the technical field.

In some embodiments, when the smoke coefficient per unit area of the second sub-layer 101 is lower than 60, it means that the flame-resistant material in the second sub-layer 101 meets the flame-resistant secondary material in the building regulations. For example, the second sub-layer 101 may include wood wool cement board, flame-resistant gypsum board, or any combination thereof, or flame-resistant secondary materials recognized by those with ordinary knowledge in the technical field.

In some embodiments, when the smoke emission coefficient per unit area of the second sub-layer 101 is lower than 30, it means that the flame-resistant material in the second sub-layer 101 meets the flame-resistant first-class material in the building regulations. More specifically, the flame-resistant first-class materials will not cause combustion, melting, rupture, deformation, and harmful gas generation due to fire heat. Therefore, the use of first-class flame-resistant materials can significantly improve the fire-proof capability of the sound insulation board 1A. For example, the second sub-layer 101 may include concrete, bricks, hollow bricks, tiles, stone, artificial stone, asbestos products, steel, aluminum, glass, glass fiber, mineral wool, ceramics, mortar, lime, or any of them. Combination, or flame-resistant first-class materials recognized by those with ordinary knowledge in the technical field.

The locking component 11 is arranged on the second sub-layer 101. The locking assembly 11 is used to install the sound insulation board main body 10 on the wall of the house. More specifically, the locking component 11 may include a plurality of locking accessories 110, and the plurality of locking accessories 110 are respectively disposed on the second sub-layer 101. Each of the plurality of locking accessories 110 may include a locking hole 110A and a screw 110B. For example, the number of the locking holes 110A may be four, and the four locking holes 110A are respectively provided on the four corners of the second sub-layer 101 (as shown in FIG. 2). Alternatively, in some other embodiments, the number of the locking holes 110A may be twelve. Twelve locking holes 110A may be spaced apart on the four sides of the second sub-layer 101 (for example, each side has three locking holes 110A). Two ends of the screw 110B correspond to the locking hole 110A and the wall respectively. In this way, the construction personnel can quickly install the sound insulation board 1A on the wall through the locking holes 110A and the screws 110B. It should be noted that the number of locking holes 110A described above is only an example, and the application is not limited to this. The number of locking holes 110A in the present application can be 4, 8, 12, or more than 12, and different numbers can be set according to actual conditions.

In some embodiments, the locking hole 110A may also be drilled through the first sub-layer 100 and the second sub-layer 101. In this case, the first sub-layer 100 and the second sub-layer 101 can be connected to each other by the locking hole 110A and the screw 110B. The above-mentioned "connection" can be a direct connection or an indirect connection. For example, the first sub-layer 100 and the second sub-layer 101 can be separated from each other by a certain distance by using elements such as a screw cap. When the first sub-layer 100 and the second sub-layer 101 are not in direct contact, the transmission of vibration and heat energy can be effectively reduced.

Please refer to FIG. 3, which is a cross-sectional view of a sound insulation board according to another embodiment of the present application. As shown in the figure, the sound insulation board 1B includes a sound insulation board main body 10 and a locking assembly 11.

Compared with the foregoing embodiment, the sound insulation board body 10 in this embodiment further includes a first adhesive layer 102. The first adhesive layer 102 is disposed between the first sub-layer 100 and the second sub-layer 101. The first adhesive layer 102 is used to connect the first sublayer 100 and the second sublayer 101.

The first adhesive layer 102 may be a single layer or a multilayer film. For example, if the thermal expansion coefficients of the first sub-layer 100 and the second sub-layer 101 differ greatly, the first adhesive layer 102 may include a first sub-adhesive layer and a second sub-adhesive layer, and the first sub-adhesive layer And the second sub-adhesive layer may have different thermal expansion coefficients. More specifically, the first sub-layer 100 is first adhered to the first sub-adhesive layer with similar thermal expansion coefficient, and the second sub-layer 101 is adhered to the second sub-adhesive layer with similar thermal expansion coefficient, and finally the first sub-adhesive layer and The second sub-adhesive layers are adhered to each other. By providing multi-layer films with different thermal expansion coefficients, the adhesion between the first sub-layer 100 and the second sub-layer 101 can be made more stable. However, the above two layers are only examples, and the application is not limited thereto. In other embodiments, the first adhesive layer 102 may be a multi-layer film with more than two layers. For example, the first adhesive layer 102 may be a three-layer, four-layer, five-layer, or a multi-layer film with more than five layers. In addition, the above-mentioned coefficient of thermal expansion is only an example, and the present application is not limited to this.
