Problems solved by technology

But the well-known critical frequency propagation loss performance degradation is particularly detrimental to the sound insulation ability of glass, that is, vibrating glass becomes an efficient sound radiator at or above a certain frequency.
As a result, the glass becomes transparent to sound causing transmission loss droop, and increasing glass thickness does not effectively resolve transmission loss droop
Moreover, laminated glass can only be applied to the window part of the building, and cannot be used on other wall parts of the building.

Embodiment 1

[0046] Such as figure 1 As shown, a soundproof wall sticker includes a decorative layer 1, a non-woven fabric layer 3, and a soundproof layer 2 for sound insulation. One side of the soundproof layer 2 and the decorative layer 1 are bonded by an adhesive layer B, and the soundproof layer 2 The other side of and the non-woven fabric layer 3 are bonded by the adhesive layer A.

[0047] The thickness of the sound insulation layer 2 is 0.01-5 mm, the thickness of the non-woven fabric layer 3 is 0.01-2 mm, and the sum of the thicknesses of the decorative layer 1, the sound insulation layer 2 and the non-woven fabric layer 3 is 0.2-10 mm.

[0048] The sound insulation layer 2 is made of high-damping rubber and is vulcanized rubber with a damping coefficient greater than or equal to 0.3, preferably the vulcanized rubber with a damping coefficient greater than or equal to 0.4. Rubber is a high-elastic polymer material. The damping of rubber is the internal frictional resistance of the movem...

Embodiment 2

[0054] Such as figure 2 As shown, the sound insulation layer 2 includes a plurality of sound insulation sheets 21, and the plurality of sound insulation sheets 21 are laminated by pressing sheets. The plurality of sound insulation sheets 21 can be made of the same type of rubber, and the plurality of sound insulation sheets 21 can also be of different types. The multiple sound-insulating sheets 21 can be made of rubber with the same damping coefficient, and the multiple sound-insulating sheets 21 can also be made of rubber with different damping coefficients.

[0055] This embodiment is the same as the first embodiment except that the above-mentioned structure is different from the first embodiment.

Embodiment 3

[0057] Such as figure 1 with 3 As shown, a method for producing a soundproof wall sticker includes the following steps:

[0058] Step one: calender the sound-insulating material into a sheet structure with a calendering equipment to form the sound-insulating layer 2.

[0059] The rolling thickness of the sound insulation layer 2 is made into a thickness of 0.01-5mm, and the thickness of the sound insulation layer 2 is 0.01-5mm, preferably a soundproof layer 2 with a thickness of 0.1-3mm, more preferably a soundproof layer with a thickness of 0.2-2mm 2.

[0060] Step two, bonding one side of the sound insulation layer 2 with the non-woven fabric layer 3;

[0061] Use non-woven materials to make a non-woven fabric layer 3 with a thickness of 0.01-2 mm, preferably a non-woven fabric layer 3 with a thickness of 0.01-1 mm, more preferably a non-woven fabric layer 3 with a thickness of 0.01-0.5 mm; The machine coats the adhesive uniformly on the surface of the non-woven fabric layer 3, so ...

Abstract

The invention relates to the field of decorative building materials and particularly relates to a sound insulation wall coat layer including a decorative layer, a non-woven cloth layer and a sound insulation layer for insulating sounds. One side of the sound insulation is adhered to the decorative layer via an adhesive layer B; the other side of the sound insulation is adhered to the non-woven cloth layer via an adhesive layer A. The sound insulation wall coat layer has simple structure, is convenient to use, is low in cost and is aesthetic, wherein the non-woven cloth layer has certain soundabsorption effect, and furthermore, with combination of the sound insulation layer, transmission of sound is weakened, so that the sound insulation wall coat layer has excellent sound insulation effect.

Description

Technical field [0001] The invention relates to the field of decoration building materials, in particular to a soundproof wall paste layer and a production method thereof. Background technique [0002] With the rapid development of industry, agriculture, and transportation, noise pollution has become increasingly serious, especially in large and medium-sized cities with dense populations and developed economies. Noise is an unpleasant sound. When people are often exposed to noise, it can cause stress, tension, insomnia, inattention, and cardiovascular problems, which seriously disturb people's work and rest. [0003] To have a comfortable and peaceful quality of life, it is necessary to isolate the noise outside the building. However, the sound insulation effect of traditional building wall sound insulation materials is not ideal. The thickness and volume of the sound insulation materials are large and the indoor space is compressed, and the later maintenance and replacement proce...
