The diameter of the polyphenyl granules is 3-4 mm. The cement foamed board in unit volume at least contains 60% of polyphenyl granules, and the closed cell rate of the cement foamed board in unit volume is more than 90%. The utility model discloses on can guaranteeing the basis of certain intensity, realize on a large scale giving sound insulation, it is good to realize noise reduction effect.
Description
Technical Field
The utility model relates to a building materials field gives sound insulation, in particular to double-deck compound rock wool board.
Background
Materials that can be used to block noise are collectively referred to as sound insulation materials. The sound insulation material is a five-flower eight-door, and daily people commonly use solid bricks, reinforced concrete walls, wood boards, gypsum boards, iron boards, sound insulation felts, fiber boards and the like. In a strict sense, almost all materials have a sound-insulating effect, and the difference is that the sound volume of the intervals of different materials is different. The sound insulation amount of the same material is greatly changed due to different areal densities. The sound insulation quantity follows the principle of mass law, namely, the larger the unit dense area density of the sound insulation material is, the larger the sound insulation quantity is, and the area density and the sound insulation quantity are in direct proportion.
The rock wool board is an inorganic fiber board which is made by using basalt as main raw material and through high-temperature melting processing, and the artificial inorganic fiber which is made by using the rock wool board through high-temperature melting processing has the characteristics of light weight, small heat conductivity coefficient, heat absorption and non-combustion. If used on large areas of wall, the structural strength is not sufficient. And the sound absorption effect of the single rock wool board is not good.
The sound-absorbing material is provided with a plurality of small holes inside, sound waves can be reflected after entering the sound-absorbing material, and the sound can be reduced after the sound waves are superposed, so that the sound-absorbing material is generally used in places which are easy to echo, such as a studio, a cinema and the like, and the sound can be prevented from being echoed. However, if the conventional soundproof panel has a good soundproof effect, a relatively thick soundproof panel is required, but if the soundproof panel is too thick, the strength of the whole soundproof panel is lowered.
Disclosure of Invention
To exist not enough among the prior art, the utility model provides a double-deck compound rock wool board can guarantee on the basis of certain intensity, realizes on a large scale giving sound insulation, and it is good to realize the noise reduction effect.
The utility model discloses a realize above-mentioned technical purpose through following technological means.
A double-layer composite rock wool board comprises a cement foam board, a reinforcing rib, a rock wool board and a concrete layer; the concrete foaming board is characterized in that rock wool boards are respectively bonded to two ends of the cement foaming board, a plurality of polyphenyl particles are contained in the cement foaming board, the outer side of each rock wool board is coated with concrete, and reinforcing ribs are arranged between the rock wool boards and the concrete layer.
Further, the diameter of the polyphenyl granules is 3-4 mm.
Further, the cement foam board contains at least 60% by volume of polyphenyl particles in a unit volume, and the closed cell rate of the cement foam board in a unit volume is more than 90%.
Furthermore, the reinforcing ribs are steel wire meshes.
Further, the ratio of the thickness of the cement foaming plate to the thickness of the rock wool plate ranges from 1:1 to 1: 2.5.
Further, the concrete layer is diluted C20 concrete.
The beneficial effects of the utility model reside in that:
1. double-deck compound rock wool board, through including a plurality of polyphenyl granules in the cement foaming board, the rock wool board bonds respectively at cement foaming board both ends, is equipped with the strengthening rib between rock wool board and the concrete layer, on can guaranteeing the basis of certain intensity, realize on a large scale giving sound insulation, it is good to realize noise reduction effect.
2. Double-deck compound rock wool board, contain the polyphenyl granule of 60% volume at least in the cement foaming board through unit volume, unit volume the closed pore rate of cement foaming board is greater than 90%, can guarantee compound rock wool board syllable-dividing effect.

Detailed Description
The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.
As shown in fig. 1, the double-layer composite rock wool board of the present invention comprises a cement foam board 1, a reinforcing rib 3, a rock wool board 2 and a concrete layer 4; the concrete foaming board is characterized in that rock wool boards 2 are respectively bonded at two ends of the cement foaming board 1, a plurality of polyphenyl particles are contained in the cement foaming board 1, the outer side of each rock wool board 2 is coated with a concrete layer 4, and reinforcing ribs 3 are arranged between the rock wool boards 2 and the concrete layer 4. The concrete layer 4 is diluted C20 concrete. Contain a plurality of polyphenyl granules through in the cement foaming board 1, rock wool board 2 bonds respectively at 1 both ends of cement foaming board, is equipped with strengthening rib 3 between rock wool board 2 and the concrete layer 4, can guarantee on the basis of certain intensity, realizes on a large scale giving sound insulation, and it is good to realize noise reduction effect. The reinforcing ribs 3 are steel wire meshes.
The diameter of the polyphenyl granules is 3-4 mm. The cement foam board 1 in unit volume at least comprises 60% of polyphenyl granules in unit volume, and the closed cell rate of the cement foam board 1 in unit volume is more than 90%.
Fig. 1 is an embodiment of the present invention, which is used for partition walls in KTV, the diameter of the polyphenyl granules is 3-4 mm, the cement foam board 1 in unit volume contains 60% volume of polyphenyl granules, and the closed cell rate of the cement foam board 1 in unit volume is 95%.
