Abstract
The utility model discloses a silencing aluminum-plastic composite board which is characterized in that a core board is internally provided with a plurality of spiral silencing holes, the spiral silencing holes are uniformly distributed on the core board, the inner walls of the spiral silencing holes are covered with small pits, and the small pits are internally coated with sound absorption coating. On silencing aluminum-plastic composite boards of same thickness, the spiral silencing holes have greater inner wall surface area compared with vertical through holes, and the area of impact with sound waves can be increased. When sound is transmitted into the spiral silencing holes, sound waves impact the inner walls and are absorbed. As the spiral silencing holes are spirally curved channels, sound is propagated back and forth in the holes, the small pits coated with sound absorption coating on the inner walls can repeatedly absorb noise, and the sound absorption ability is greatly improved. Thus, the silencing aluminum-plastic composite board has good sound absorption and insulation effects.
Description
Technical field
The utility model relates to a kind of building materials, and more particularly, it relates to a kind of noise reduction composited aluminum and plastic decking.
Background technology
Aluminium-plastic panel is as a kind of new decorative material, from late nineteen eighties the early 1990s in last century, from Korea S and Taiwan, be introduced into China, just with the diversity of its economy, optional color, construction method, good processing characteristics, excellent fire line and noble quality easily, be subject to rapidly people's favor.Make a general survey of many novel buildings of rising sheer from level ground, be not difficult to seek betwixt its trace.Can have after some aluminium-plastic panel Practical Completions, 3 two months at least, at most in a year or so, just there are quality problems, make a lot of owners feel headache.Composited aluminum and plastic decking is to take through chemically treated application aluminium sheet to be skin-material, with vinyon, to be core, the compound substance processing on special-purpose aluminium-plastic panel production equipment.The special performance that composited aluminum and plastic decking itself has, has determined its extensive use: it can be for building exposed wall, curtain wallboard, old building transforming renovation, indoor wall and ceiling finishing, advertising signboard, exhibition bench frame, purification dustproof engineering.Composited aluminum and plastic decking is used at home in a large number, belongs to a kind of new decorative material for building, but aluminium-plastic panel of the prior art exists sound absorbing power poor, and soundproof effect is not good.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of noise reduction composited aluminum and plastic decking with stronger sound absorbing power.
For achieving the above object, the utility model provides following technical scheme: a kind of noise reduction composited aluminum and plastic decking, comprise central layer, upper aluminium sheet, lower aluminum sheet and adhesive film, described upper and lower aluminium sheet lays respectively at central layer both sides and is fixedly connected with by adhesive film, in described central layer, be provided with some spirality bloops, described spirality bloop is evenly distributed on central layer, and the inwall of described spirality bloop is covered with little concave point, in described little concave point, scribbles sound deadening coating.
The utility model is further set to: in described spirality bloop, be filled with noise reduction asbestos.
The utility model is further set to: described spirality bloop array distribution on central layer, the position of adjacent two row's spirality bloops is interlaced.
The utility model is further set to: described upper aluminium sheet and lower aluminum sheet surface are provided with protective seam.
The utility model is further set to: the described protective seam corrosion protection prime coat of attaching most importance to.
By adopting technique scheme, on the noise reduction composited aluminum and plastic decking of same thickness, compare vertical through hole, spirality bloop has larger inner wall surface area, can increase the collision area with sound wave, in the time of in transmission sound arrives this spirality bloop, sound wave can produce and collide and be absorbed with inwall, because spirality bloop is the passage of a helical buckling, so sound can be in hole propagation back and forth repeatedly, on its inwall, be covered with the little concave point that scribbles sound deadening coating and just can repeatedly absorb noise, greatly improved sound absorbing power, so this noise reduction composited aluminum and plastic decking has good sound-absorbing, soundproof effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model noise reduction composited aluminum and plastic decking embodiment;
Fig. 2 is the structural representation of central layer;
Fig. 3 is the topology layout schematic diagram of spirality bloop on central layer.
Reference numeral: 1, central layer; 11, spirality bloop; 2, upper aluminium sheet; 3, lower aluminum sheet; 4, protective seam.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model noise reduction composited aluminum and plastic decking embodiment is described further.
A kind of noise reduction composited aluminum and plastic decking, comprise central layer 1, upper aluminium sheet 2, lower aluminum sheet 3 and adhesive film, described upper and lower aluminium sheet 3 lays respectively at central layer 1 both sides and is fixedly connected with by adhesive film, in described central layer 1, be provided with some spirality bloops 11, described spirality bloop 11 is evenly distributed on central layer 1, the inwall of described spirality bloop 11 is covered with little concave point, in described little concave point, scribbles sound deadening coating.On the noise reduction composited aluminum and plastic decking of same thickness, compare vertical through hole, spirality bloop 11 has larger inner wall surface area, can increase the collision area with sound wave, when transmission sound is interior to this spirality bloop 11, sound wave can produce and collide and be absorbed with inwall, because spirality bloop 11 is passages of a helical buckling, its passage length very, after sound admission passage, understand propagation back and forth repeatedly in hole, on its inwall, be covered with the little concave point that scribbles sound deadening coating and just can repeatedly absorb noise, greatly improved sound absorbing power, so this noise reduction composited aluminum and plastic decking has good sound-absorbing, soundproof effect.
In described spirality bloop 11, be filled with noise reduction asbestos, noise reduction asbestos have good sound-absorbing effect, coordinate with little concave point, at the interior repeated absorption noise of spirality bloop 11, have effectively improved the ability of absorbing sound and lowering noise.
Described spirality bloop 11 array distribution on central layer 1, the position of adjacent two row's spirality bloops 11 is interlaced.By rational layout, make, the spirality bloop 11 that distributes more on the central layer 1 of unit area, is strengthened the sound absorbing power of this noise reduction composited aluminum and plastic decking to greatest extent.
Described upper aluminium sheet 2 and lower aluminum sheet 3 surfaces are provided with protective seam 4, the described protective seam 4 corrosion protection prime coat of attaching most importance to.Protective seam 4 can be protected upper and lower aluminium sheet 3; heavily corrosion protection prime coat by together heavily corrosion protection priming paint evenly coating form; therefore heavily corrosion protection priming paint has excellent adhesion, weatherability, water tolerance, rust-preventing characteristic, acid resistance, oil resistance, solvent resistance impact strength, flexing resistance permanance, wearing quality, thereby weatherability, water tolerance, rust-preventing characteristic, acid resistance, oil resistance, solvent resistance impact strength, flexing resistance permanance, the wearing quality that can improve noise reduction composited aluminum and plastic decking extend its serviceable life.
