Problems solved by technology

[0002] In the field of construction, wall panels are one of the most common building materials. Nowadays, many wall panels are made of perforated bricks or fly ash bricks. In this way, the construction strength is high, and the construction site is easy to cause pollution, and the wall panels themselves are not There is no function of sound insulation and fire prevention, which seriously affects the normal life of residents. There are also many sound insulation panels on the market, but most of these sound insulation panels are single-layer structures, and the sound insulation effect is very poor.

Embodiment 1

[0027] Such as Figures 1 to 4 The shown sound-insulating building board includes a substrate layer 1 , a first sound-insulating layer 2 , a second sound-insulating layer 3 and a panel layer 4 sequentially from inside to outside. In the present invention, the panel layer is coated with a waterproof and wear-resistant coating.

[0028] The first sound insulation layer 2 sequentially includes the first sound insulation cotton layer 21, the glass fiber mesh cloth layer 22 and the second sound insulation cotton layer 23 which are closely attached from the inside to the outside. The design of the first sound insulation layer, on the one hand, the first sound insulation The cotton layer and the second sound-insulating cotton layer have the function of heat insulation, and the glass fiber mesh cloth layer has the function of heat preservation, so that the alternation of cold and heat inside and outside can be reduced. In winter, the indoor heat is not easy to go out; in summer, the ...

Embodiment 2

[0033] Such as figure 1 , 3 , 6, 7 shows a kind of sound insulation building board, which includes substrate layer 1, first sound insulation layer 2, second sound insulation layer 3 and panel layer 4 in order from inside to outside. In the present invention, the panel layer is coated with a waterproof and wear-resistant coating. The difference from Example 1 is:

[0034] The sides of the first sound-insulating cotton layer 21 and the second sound-insulating cotton layer 23 close to the glass fiber mesh layer 22 form a plurality of protrusions 5 toward the glass fiber mesh layer 22, and the protrusions 5 can be inserted into corresponding hollow parts. 222. On the one hand, the protrusions are placed in the hollowed out part and fit together, which can strengthen the strength of the glass fiber mesh cloth layer to a certain extent, and improve the strength of the first sound insulation cotton layer; In the case of the sound insulation quality of the sound insulation cotton,...

Embodiment 3

[0038] Embodiment 3: as image 3 , 5 A sound-insulating building board shown in 7 includes a substrate layer 1 , a first sound-insulating layer 2 , a second sound-insulating layer 3 and a panel layer 4 sequentially from inside to outside. In the present invention, the panel layer is coated with a waterproof and wear-resistant coating. The difference from Example 2 is:

[0039] The hollow part 222 is provided with sound-insulating filling particles. When producing the first sound insulation layer, first cover the glass fiber mesh cloth layer on the first sound insulation cotton layer or the second sound insulation cotton layer, and then fill the hollow part with some porous sound insulation filling particles, such as ceramics and bentonite, and then cover Another layer of sound-proof cotton is pressed to form the first sound-proof layer. This operation can further improve the effect of sound insulation, and also improve the thermal insulation effect of the glass fiber mesh ...

Abstract

The invention discloses a sound-proof building board which comprises a base plate layer, a first sound-proof layer, a second sound-proof layer and a panel layer from inside to outside in turn; the first sound-proof layer includes a first sound-proof cotton layer, a glass fiber mesh cloth layer and a second sound-proof cotton layer fitted closely from inside to outside in turn, and the glass fibermesh cloth layer comprises a fiber part and a hollow part; the second sound-proof layer comprises a foam glass plate passing through the length direction of the sound-proof building plate and a wood plate arranged in a through groove. The sound-proof building board has the advantages of good sound-proof effect, good stability and long service life.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a sound-insulating building board. Background technique [0002] In the field of construction, wall panels are one of the most common building materials. Now many wall panels are made of perforated bricks or fly ash bricks. In this way, the construction strength is high, and the construction site is easy to cause pollution, and the wall panels themselves are not There is no function of sound insulation and fire prevention, which seriously affects the normal life of residents. At present, there are many sound insulation panels on the market, but most of these sound insulation panels are single-layer structures, and the sound insulation effect is very poor. Contents of the invention [0003] The object of the present invention is to propose a sound-insulating building board aiming at the above-mentioned deficiencies of the prior art. [0004] The technical solution adopt...
