Abstract
The utility model discloses a kind of composite damping sound insulationg board, including the first glass magnesium board, bitumen layer and the second glass magnesium board being arranged successively, the first glass magnesium board with a thickness of 6mm, bitumen layer with a thickness of 2mm, the second glass magnesium board with a thickness of 8mm.The composite damping sound insulationg board selects the damping layer of 2mm, greatly reduces the spread speed of sound, reach certain sound insulation effect according to the propagation characteristic of sound, damping layer；Meanwhile the glass magnesium board with a thickness of 6mm and 8mm is respectively adopted in two surface layers, by considering that sound propagates penetrability and refraction performance in same material, two surface layers are better than using same thickness using the sound insulation effect of different-thickness；The composite damping sound insulationg board has good sound insulation effect as a result, and oise insulation factor reaches 35dB.
Description
Technical field
The utility model belongs to a kind of sound insulation product, more particularly, to a kind of composite damping sound insulationg board.
Background technique
Current indoor sound insulation mode generallys use the traditional materials such as some general decor planks, and material is mounted on building
On the smallpox of object, wall and the substrate on ground.Often there is following situation in this mode：Density of material is relatively low, and sound transmission loss is poor；Material
Material is not selected according to the sound in place in the fast slow characteristic of propagation of various media, so without apparent deadening；One
As material be all homogenous material, soundproof effect is unobvious.
As the living standard of the people constantly improves, while the demand of spiritual civilization life increases, more and more joys
Happy place is increasing.However as the progress of science and technology, the acoustic pressure that stereo set can generate is also increasing.Due to domestic and international needle
Really few to the research of soundproofing field, the method and data that can refer to are fewer, so most of place is all seldom specially done
Good sound insulation processing.
Utility model content
The purpose of this utility model is to provide a kind of composite damping for being able to solve at least one of above problem every
Sound plate.
One aspect according to the present utility model provides a kind of composite damping sound insulationg board, including be arranged successively first
Glass magnesium board, bitumen layer and the second glass magnesium board, the first glass magnesium board with a thickness of 6mm, bitumen layer with a thickness of 2mm, the second glass magnesium board
With a thickness of 8mm.
The utility model has the beneficial effects that：Propagation characteristic of the composite damping sound insulationg board according to sound, damping layer selection
The damping layer of 2mm greatly reduces the spread speed of sound, reaches certain sound insulation effect；Meanwhile two surface layers are respectively adopted
With a thickness of the glass magnesium board of 6mm and 8mm, by considering that sound propagates penetrability and refraction performance, two surface layers in same material
It is better than using same thickness using the sound insulation effect of different-thickness；The composite damping sound insulationg board has sound insulation effect well as a result,
Fruit, oise insulation factor reach 35dB.
In some embodiments, bitumen layer is environmental-protective self-adhering pitch.As a result, bitumen layer have vibration damping, noise reduction and
Etch-proof effect.
In some embodiments, composite damping sound insulationg board further includes shock absorption strip, and the first glass magnesium board surrounding offers recessed
Slot, shock absorption strip are mounted in groove, and the outer edge of shock absorption strip exceeds the outer edge of the first glass magnesium board side.It is equipped with damping as a result,
Item can reduce the vibration in a noisy environment of entire composite damping sound insulationg board, meanwhile, composite damping sound insulationg board can be made
During installation, the planarization of the leakproofness and splicing between adjacent panels is improved.
In some embodiments, the bottom surface of the second glass magnesium board offers multiple mounting holes.It is equipped with mounting hole as a result, it can
To facilitate the installation of the composite damping sound insulationg board on wall.
In some embodiments, the apparent density of the first glass magnesium board and the second glass magnesium board is 2360~2460kg/m3。
Sound insulation effect can be enhanced using highdensity glass magnesium board as a result,.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the composite damping sound insulationg board of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Referring to Fig.1.Composite damping sound insulationg board, including the first glass magnesium board 1, bitumen layer 2 and the second glass magnesium board being arranged successively
3, the first glass magnesium board 1 with a thickness of 6mm, bitumen layer 2 with a thickness of 2mm, the second glass magnesium board 3 with a thickness of 8mm；Lead between each layer
Bonding agent is crossed to be adhesively fixed.
Wherein, the apparent density of the first glass magnesium board 1 and the second glass magnesium board 3 is 2360~2460kg/m3, it is high density glass
Magnesium plate contains glass fiber reticular cloth in glass magnesium board, and the material of the two is identical, has reached preferable sound insulation effect.
The composite damping sound insulationg board of the utility model passes through sound equipment power amplifying device noise emissions mainly for bar, KTV etc.
Serious public place of entertainment, that selects the applicable acoustic material of relativity to better solve that section public place of entertainment noise emissions disturb residents asks
Topic, especially there is relatively good performance in acoustic low-pass part.
Bitumen layer 2 is environmental-protective self-adhering pitch, based on modified pitch, with excellent damping noise reduction performance and firmly
Adhesive force.
The composite damping sound insulationg board further includes shock absorption strip 4, and 1 surrounding of the first glass magnesium board opens up fluted, the installation of shock absorption strip 4
In groove, the outer edge of shock absorption strip 4 exceeds the outer edge of 1 side of the first glass magnesium board.Wherein, shock absorption strip 4 can be rubber strip,
Can increase adjacent composite damping sound insulationg board splicing when planarization, and can reduce installation after composite damping sound insulationg board it is whole
The vibratility of a metope.
The bottom surface of second glass magnesium board 3 offers multiple mounting holes.Mounting hole can be threaded hole, and threaded hole is evenly arranged on second
Each apex of glass magnesium board 3 can be convenient the installation of composite damping sound insulationg board by being equipped with mounting hole, improve installation effectiveness.
In order to further increase the sound insulation effect of the composite damping sound insulationg board, composite damping sound insulationg board further includes deadening felt,
Deadening felt is fixed on the bottom of the second glass magnesium board 3, i.e., between the second glass magnesium board 3 and wall.
