Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, the technical solution in embodiment is carried out it is clear, complete
Ground description.Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts
There are other embodiments, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of alluminium decorating plate of absorbing sound and lowering noise, including aluminum substrate 1, panel 3, it is set to 1 and of aluminum substrate
Sound-absorbing component 2 between panel 3, the sound-absorbing component 2 include the sound absorbing layer 21 and puigging 22 set gradually, the sound absorbing layer
21 be to connect the internal voids of panel 3 and aluminum substrate 1 to gradually become smaller the nonwoven layer for becoming close from outside to inside, such as can for multilayer without
Woven fabric is combined by fibre density is successively low from low to high, and a few septum femorale intermedium silks are introduced when can also pass through braiding, is formed internal empty
Gap gradually becomes smaller the sound absorbing layer 21 for becoming close from outside to inside；The puigging 22 is keriotheca.The sound wave come from noise source is used as
Ejected wave is incident in sound-absorbing component 2 via panel 3, and fraction is reflected by panel 3, most of to be absorbed by sound-absorbing component 2, another portion
Divide to be converted into and penetrate sound, is balanced out by keriotheca, further more, the back wave from the panel 3 is synthesized with incidence wave, arrived as standing wave
Up to sound-absorbing component 2.The staggered porous structure of fiber can be used for sound-absorbing in nonwoven layer, and sound absorbing layer 21 makes the sky of Acoustic Wave Propagation on the way
Gap becomes smaller more, greatly reduces the propagation and reflection of sound wave, thus reinforcement sound can consumption, sound-absorbing effect is obvious, especially
Centering high frequency sound wave.Keriotheca is made of cellular board, and internal is honeycomb structure, and hole interpenetrates, and is full of air, many
Well known, sound propagation velocity is most slow in air, thus can effectively prevent sound transmission, penetrate sound and decay through sound absorbing layer 21
Sound wave reach keriotheca after, absorb the deformation energy for shaking and being converted to core material by its internal honeycomb core and slow release, make
Noise is significantly decayed, in addition, the vibration of air and cellular board can be caused after sound wave enters honeycomb core, due to by
Air molecule friction and viscosity resistance enable a part of sound to be converted into thermal energy and lose, and then noise are effectively reduced, and realize drop
It makes an uproar function；Honeycomb also improves the rigidity and intensity of alluminium decorating plate itself simultaneously.
In the present embodiment, hollow glass micropearl 23, hollow glass micropearl are filled in the internal cellular hole of the keriotheca
23 be a kind of small, hollow ball sprills, the only thin gas in inside, sound insulation, heat-insulated good, micro- by hollow glass
Pearl 23 increases porosity and viscosity resistance, greatly increases the propagation path of sound wave, " locks " sound wave in turn, is reflecting sound wave
Middle continuation is absorbed by cellular board, and the maximized absorbing sound and lowering noise effect for playing cellular board enhances sound-absorbing effect；Secondly, by honeycomb
Plate and hollow glass micropearl 23 are used in combination, and can expand sound-absorbing range, improve sound-absorption coefficient；As a result, being reached from noise source
The sound wave of sound absorbing layer 21 is suitably decayed by the sound absorbing layer 21, and rest part penetrates sound absorbing layer 21, reaches keriotheca, then by honeycomb
Plate and hollow glass micropearl 23 completely consume, and can prevent sound wave from exporting as noise to 1 side of aluminum substrate.
In the present embodiment, the sound-absorbing component 2 further includes reinforcing prop 24, and the reinforcing prop 24 is evenly distributed on aluminum substrate
Between 1 and panel 3, i.e., reinforcing prop 24 penetrates sound-absorbing component 2, and one end is Nian Jie with aluminum substrate 1, and the other end is Nian Jie with panel 3, uses
In reinforcing the bonding strength between panel 3, sound-absorbing component 2 and aluminum substrate 1, alluminium decorating plate overall structure is promoted to stablize, to mention
Whole intensity is risen, sound-absorbing component 2 is unlikely to deform, suitable for the use of Indoor decorative plate, avoids using rear plate body for a long time
Deformation, extends the service life of cellular board.Preferably, the reinforcing prop 24 is made of metal material；Metal material has good
Thermal conductivity, heat can be conducted outward, effectively cooled down to alluminium decorating plate, avoided as gathered heat in summer room under high-heat environment,
So that sound-absorbing component 2 has both noise reduction and thermally conductive function simultaneously.
In the present embodiment, the panel 3 is perforated plate, and punching rate is 3%~5%, in order to eliminate different noises
The diameter of frequency, perforation is different, spaced apart by the barrier and wall of sound-absorbing component 2 to improve erasure effect
Installation, to form many a cavities, when the frequency of sound wave is consistent with the natural frequency of vibration of perforated plate, resonates, and
Amplitude is set to reach maximum, so that sound energy consumption, achievees the purpose that sound absorption, absorption is maximum in low frequency, and when high frequency is reduced, from
And total absorption band is made to broaden, further expansion sound absorption range；Secondly, before perforated plate is set to sound absorbing layer 21 and puigging 22
Side, sound absorbing layer 21 and puigging 22 can increase the air drag near pore-throat, further increase sound energy loss, enhancing sound-absorbing effect
Fruit.
In the present embodiment, the panel 3 is made of one of metal plate, cement asbestos board.
In the present embodiment, the top of the sound absorbing layer 21 is equipped with one layer of polytetrafluoroethylene ethylene layer 4, it is preferred that the polytetrafluoro
The surface of pvdf layer 4 is equipped with several hole lines and enhances collision area to make the rough surface of entire sound-absorbing component 2, therefore,
Also erasure effect can be further enhanced；And 4 surface of polytetrafluoroethylene ethylene layer of concave-convex type, the shape between sound absorbing layer 21 and perforated plate
At air layer, due to the presence of the air layer, vibration can more easily be generated by the sound wave for reaching perforated plate from noise source,
Preferably decaying sound wave.
In the present embodiment, the panel 3, sound-absorbing component 2 and aluminum substrate 1 using TPE adhesive bond at an entirety,
Just bonding force is strong for TPE bonding agent, and glue film is flexible, and impact resistance and vibration resistance ability are strong, and ageing-resistant ability is good, can be for a long time
Each layer is bonded so that the alluminium decorating plate of the utility model is not allowed fugitive, stability is high.
