Embodiment 1

[0025] refer to figure 1 , this embodiment provides a sound insulation wall for a studio, comprising a first wall 1 and a second wall 5, a sound insulation module is arranged between the first wall 1 and the second wall 5, and the sound insulation The module includes a first sound-absorbing cotton layer 2, a second sound-absorbing cotton layer 4 and a damping plate 3 arranged between the first sound-absorbing cotton layer 2 and the second sound-absorbing cotton layer 4, the first sound-absorbing cotton layer 2 and the second sound-absorbing cotton layer Both sides of the second sound-absorbing cotton layer 4 are coated with adhesive, and the sides of the first wall 1 and the second wall 5 away from the sound-insulating module are sprayed with paint.

[0026] Among them, in order to enhance the supporting and fixing effects of the first sound-absorbing cotton layer 2 and the second sound-absorbing cotton layer 4, keels, preferably light steel keels, are arranged in the first so...

Embodiment 2

[0029] The provision of a sound insulation wall for a broadcasting room in this embodiment is an improvement on the basis of Example 1, the difference is that the adhesive is prepared from the following components by weight: 25 parts of polyacrylamide, 15 parts of sodium silicate 5 parts, 5 parts of filler, 6 parts of additive, 3 parts of Terotex-218 soundproof agent, 2.5 parts of surfactant, 23 parts of acetone, 40 parts of water.

[0030] The filler is a mixture of kaolin, silicon carbide and titanium dioxide, the weight ratio of kaolin: silicon carbide: titanium dioxide is 1:2:4, and the particle size is 200 mesh.

[0031] The auxiliary agent is a mixture of sodium chromate, nonylphenol polyoxyethylene ether and p-toluenesulfonic acid, and the weight ratio of sodium chromate: nonylphenol polyoxyethylene ether: p-toluenesulfonic acid is 1:5:3.5.

[0032] The surfactant is dioctyl sodium sulfosuccinate.

Embodiment 3

[0034] The provision of a sound insulation wall for a broadcasting room in this embodiment is an improvement on the basis of Embodiment 1, the difference is that: the adhesive is prepared from the following components by weight: 27 parts of polyacrylamide, sodium silicate 18 parts, 6 parts of filler, 6.5 parts of additives, 4 parts of Terotex-218 soundproof agent, 3 parts of surfactant, 25 parts of acetone, 42 parts of water.

[0035] The filler is a mixture of kaolin, silicon carbide and titanium dioxide, the weight ratio of kaolin: silicon carbide: titanium dioxide is 1:3:4, and the particle size is 250 mesh.

[0036] The auxiliary agent is a mixture of sodium chromate, nonylphenol polyoxyethylene ether and p-toluenesulfonic acid, and the weight ratio of sodium chromate: nonylphenol polyoxyethylene ether: p-toluenesulfonic acid is 1:5:4.

[0037] The surfactant is sodium laurylalanine.

Abstract

The invention provides a sound insulation wall for a studio, and belongs to the technical field of sound pollution control. The sound insulation wall for a studio comprises a first wall body and a second wall body, wherein the first wall body and the second wall body are provided with a soundproof module therebetween, the soundproof module includes a first sound absorbing cotton layer, a second sound absorbing cotton layer, and a damping plate disposed between the first sound absorbing cotton layer and the second sound absorbing cotton layer, each of the first sound absorbing cotton layer andthe second sound absorbing cotton layer is provided with a binder on both sides, and each of the first wall and the second wall is sprayed with paint on a side away from the soundproof module. The sound insulation wall has good sound insulation effect, and solves the problem that the sealed sound insulation device is detachably connected, the fixation is not firm, the contact between adjacent components is not tight, and the sound leakage is caused. Meanwhile, the binder for adhesion between the components of the sound insulation wall is additionally provided. The joint strength is excellent and the sound insulation effect is good.
