Description
Technical field
The utility model relates to plate technical field more particularly to a kind of lightweight Composite sound-proof wall plates of insulating against sound.
Background technique
With economic and industrial fast development, noise control gradually becomes particularly important.In the noise of building
In prevention and treatment, existing metope is transformed frequently with some sound-absorbing materials, or directlys adopt with certain soundproof effect
Wallboard.However, the existing most soundproof effect of Acoustic barrier plate is bad, and structure is complicated, is increased by way of stacking charging to it
It adds thickness to reach corresponding oise insulation factor, causes the thickness of wallboard thicker, heavier-weight is not suitable for the construction of modern building.
Utility model content
The purpose of this utility model is to provide the good wallboards of a kind of light weight, environmental protection and soundproof effect.It is above-mentioned to realize
Purpose, the technical solution of the utility model are as follows:
A kind of lightweight Composite sound-proof wall plate, the wallboard are answered by the first calcium silicate board, complex sound insulation layer, the second calcium silicate board
It is combined into；
The complex sound insulation layer is in the thickness direction along wallboard by polystyrene foam filled layer, iron filings layer, silicate cement
Mud layer is combined by glue；The polystyrene foam filled layer has wavy cross-section close to the side of iron filings layer, should
Polystyrene foam filled layer is formed by mould heat pressure and is formed；The iron filings layer is filled by nanometer iron powder to structure in acoustical cotton
At；
First calcium silicate board and the second calcium silicate board with a thickness of 8-12mm, the polystyrene foam filled layer
With a thickness of 15-22mm, the iron filings layer with a thickness of 8-10mm, the silicate cement mud layer with a thickness of 15-20mm.
In a certain embodiment: first calcium silicate board, complex sound insulation layer, the second calcium silicate board pass through laminated compounding
At the wallboard.
In a certain embodiment: the acoustical cotton is glass fibre acoustical cotton or polyester fiber acoustical cotton.
Compared to the prior art, the utility model has the advantage that in complex sound insulation layer and fills out including polystyrene foam
Fill layer, polystyrene foam filled layer is closed pore construction, and porosity is higher so that sound needed when passing through this layer by compared with
Long and irregular propagation path, it is thus possible to weaken the vibration degree of sound wave；And iron filings layer is filled by nanometer iron powder to sound-absorbing
It constitutes in cotton, so that the nanometer iron powder that the sound wave of high band can make occurs high when sound is propagated further to the iron filings layer
Frequency shakes, and the high-frequency vibration of the nanometer iron powder is absorbed by acoustical cotton, and is converted into thermal energy, and since nanometer iron powder is nanometer
Grade, even if high-frequency vibration, which occurs, will not generate the sound of corresponding level, thus the noise of high frequency can be down to by the iron filings layer
Certain level；Equipped with including silicate cement mud layer in complex sound insulation layer, complex sound insulation layer in first, second calcium silicate board,
So that the structural strength of the present embodiment wall has obtained preferable guarantee.
Detailed description of the invention
Fig. 1 shows the schematic diagram of the section structure of the utility model embodiment wallboard.
Specific embodiment
Fig. 1 is please referred to, the utility model provides a kind of lightweight Composite sound-proof wall plate, and the wallboard is by the first calcium silicate board
1, complex sound insulation layer 2, the compound composition of the second calcium silicate board 3.In the present embodiment, first calcium silicate board 1, complex sound insulation layer 2,
Second calcium silicate board 3 is by laminated compounding at the wallboard.
The complex sound insulation layer 2 is in the thickness direction along wallboard by polystyrene foam filled layer 21, iron filings layer 22, silicic acid
Salt water mud layer 23 is combined by glue.The polystyrene foam filled layer 21 has wave close to the side of iron filings layer 22
Tee section, the polystyrene foam filled layer 21 are formed by mould heat pressure and are formed.The iron filings layer 22 is filled out by nanometer iron powder
It is charged in acoustical cotton and constitutes.In the present embodiment, optionally, the acoustical cotton is glass fibre acoustical cotton or polyester fiber sound-absorbing
Cotton.
It include polystyrene foam filled layer, polystyrene foam filled layer 21 in complex sound insulation layer 2 in the utility model
It is constructed for closed pore, and porosity is higher, there is wavy cross-section, so that sound is needed to pass through longer when passing through this layer and not advised
The propagation path of rule, it is thus possible to weaken the vibration degree of sound wave；And iron filings layer 22 is filled by nanometer iron powder to structure in acoustical cotton
At, so that high-frequency vibration occurs for the nanometer iron powder that the sound wave of high band can make when sound is propagated further to the iron filings layer,
And the high-frequency vibration of the nanometer iron powder is absorbed by acoustical cotton, and is converted into thermal energy, and since nanometer iron powder is nanoscale, i.e.,
Just high-frequency vibration, which occurs, will not generate the sound of corresponding level, thus the noise of high frequency can be down to certain water by the iron filings layer
It is flat.In addition, equipped with including silicate cement mud layer 23 in complex sound insulation layer, complex sound insulation layer in the first, second calcium silicate board,
So that the structural strength of the present embodiment wall has obtained preferable guarantee.
In specific structure, first calcium silicate board 1 and the second calcium silicate board 3 with a thickness of 8-12mm, the polyphenyl second
Alkene foam filled layer 21 with a thickness of 15-22mm, the iron filings layer 22 with a thickness of 8-10mm, the silicate cement mud layer 23
With a thickness of 15-20mm.Using above with postponing, in 54-76mm, sound insulation value is in the thickness range of the present embodiment wallboard
Oise insulation factor reaches the range of 35-40dB.Therefore, because relative thickness is smaller, but the Brick wall plasterer facing of oise insulation factor and 120mm thickness
It is essentially identical afterwards, so that every wallboard using every 13 meters the present embodiment, can increase about 1 square metre of usable floor area.Except this it
Outside, the wallboard of the present embodiment, the wiring that can slot, nail, which are hung, to be pasted, as needed any fluting wiring, nailing or expansion bolt hanging weight
Object, single-point hanging force >=50kg, close structure, not loose indeformable, fabricated construction, convenient transport stacks health, without sand
Slurry plastering, is substantially shorter the duration, saves material, and reduce construction and decoration rubbish.
The above is only the preferred embodiment of the present invention, is not intended to limit its scope of the patents, all to utilize this
Equivalent structure transformation made by utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain is also included in the patent protection scope of the utility model.
