DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 3The utility model provides a technical solution: a building sound insulation board with good sound insulation effect, comprising a sound insulation board body 1, the sound insulation board body 1 comprising a substrate 11, the substrate 11 is made of metal, the high-quality metal material has a higher density and hardness, can better isolate noise, and is also more durable, a plurality of vacuum cavities 12 are opened inside the substrate 11, the vacuum cavity 12 is not a completely vacuum environment, and contains a small amount of gas, while the sound insulation effect of the substrate 11 is improved by using the shock absorption and damping effect of the air, when a single vacuum cavity 12 is damaged, it will not affect the use of the remaining vacuum cavities 12, and the plurality of vacuum cavities 12 are not completely vacuum environments, but contain a small amount of gas, and the sound insulation effect of the substrate 11 is improved by using the shock absorption and damping effect of the air, and when a single vacuum cavity 12 is damaged, it will not affect the use of the remaining vacuum cavities 12, and the plurality of vacuum cavities 12 are not completely vacuum environments, but contain a small amount of gas, and the sound insulation effect of the substrate 11 is improved by using the shock absorption and damping effect of the air, and the plurality of vacuum cavities 12 are not completely vacuum environments ... The distances between the cavities 12 are the same, so that the sound insulation effect of the substrate 11 is more uniform. The first foam board 13 and the second foam board 14 are respectively installed on both sides of the substrate 11. The excellent sound insulation performance, flame retardancy and elasticity of the first foam board 13 and the second foam board 14 are conducive to enhancing the sound insulation effect and performing shock absorption and buffering on the sound insulation board body 1. The first foam board 13 and the second foam board 14 are respectively glued with a first metal mesh 15 and a second metal mesh 16 on the side away from the substrate 11, which protects the first foam board 13 and the second foam board 14, increases their strength, and is conducive to To prevent it from breaking, the first metal mesh 15 and the second metal mesh 16 are glued with the first sound insulation felt 17 and the second sound insulation felt 18 on the side away from the first foam board 13 and the second foam board 14 respectively. The fine fibers inside have a high porosity and can absorb the energy of sound waves. When the sound waves contact the sound insulation felt, their vibration energy is absorbed by the fibers and converted into heat energy, thereby reducing the energy of the sound waves. As a professional sound insulation material, it is increasingly widely used in modern buildings and home environments. The surfaces of the first sound insulation felt 17 and the second sound insulation felt 18 are respectively installed with the first waterproof film 5 and the second waterproof film 6. The waterproof performance of the sound insulation board body 1 is increased, which is beneficial to prevent the sound insulation board body 1 from getting wet. A mounting frame 2 is installed on the outer side of the sound insulation board body 1, and a magnetic metal layer 3 and a magnet layer 4 are installed on the corresponding two sides of the mounting frame 2. Through the adsorption between the magnetic metal layer 3 and the magnet layer 4, different sound insulation board bodies 1 can be quickly fixed together under the action of the mounting frame 2. A sealing gasket 7 is installed on one side of the sound insulation board body 1, which is beneficial to increase the fit between the sound insulation board body 1 and the wall, and has excellent elasticity, is not easy to tear, is suitable for the fitting surface with low temperature, and can be reused many times.

The sound inside and outside the room is reduced in volume after being absorbed by the first sound insulation felt 17 and the second sound insulation felt 18. At the same time, under the action of the first foam board 13 and the second foam board 14 in the sound insulation board body 1 and the multiple vacuum cavities 12 in the substrate 11, the sound is insulated by utilizing the sound insulation performance of the first foam board 13 and the second foam board 14 and the shock absorption and damping effect of the air in the vacuum cavity 12. At the same time, when the sound insulation board body 1 is hit, the first foam board 13 and the second foam board 14 are deformed to absorb energy and disperse it, so as to shock and buffer the sound insulation board body 1.
