Abstract
The utility model relates to a sound baffle is inhaled to door plant high efficiency, include PP board, the first film layer, inhale sound cotton and second thin layer, it is located to inhale the sound cotton the first film layer with between the second thin layer, the first film level in inhale the sound cotton with between the PP board, it is cotton -shapedly to inhale the sound cotton, the PP board comprises polyethylene and polypropylene, it comprises polypropylene and polydiethylene terephthalate to inhale the sound cotton, second film laminating cover in inhale on the sound cotton. Sound baffle is inhaled to door plant high efficiency is through utilizing the absorbing effect who inhales the sound cotton inhales the sound, simultaneously the PP board still has better syllable -dividing effect, makes through combination between them sound baffle is inhaled to door plant high efficiency has fabulous absorbing effect, and simultaneously, the preparation process is also comparatively simple.
Description
Technical field
The utility model relates to a kind of door-plate high-efficiency sound-absorbing dividing plate, relates to sound-absorbing material technical field.
Background technology
Absorptive product mostly in the market is sound deadening coating and melt-blown product etc., but along with the development of science and technology, the requirement of people to sound-absorbing effect is more and more higher, sound deadening coating, and after multilayer brushing, cushioning ability is stronger, but sound-absorbing effect is general; Melt-blown product due to structure single, sound-absorbing effect neither be fine.
Therefore be necessary to design a kind of door-plate high-efficiency sound-absorbing dividing plate, to overcome the problems referred to above.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides the door-plate high-efficiency sound-absorbing dividing plate that a kind of sound-absorbing effect is good.
The utility model is achieved in that
The utility model provides a kind of door-plate high-efficiency sound-absorbing dividing plate, comprise PP plate, the first film layer, acoustical cotton and the second thin layer, described acoustical cotton is between described the first film layer and described second thin layer, described the first film layer is between described acoustical cotton and described PP plate, described acoustical cotton is cotton-shaped, described PP plate is made up of polyethylene and polypropylene, and described acoustical cotton is made up of polypropylene and PETG, and described second thin layer is covered on described acoustical cotton.
Further, high temperature compound is adopted between described PP plate and described the first film layer.
Further, described door-plate high-efficiency sound-absorbing dividing plate is used in the car door of car.
Further, the thickness of described door-plate high-efficiency sound-absorbing dividing plate is 4-6mm.
Further, described the first film layer is identical with the composition of described acoustical cotton with described second thin layer.
Further, described second thin layer has multiple equally distributed micropore.
Further, the density of described acoustical cotton is 50g/m
2-600g/m
2.
The utility model has following beneficial effect:
Comprise PP plate, the first film layer, acoustical cotton and the second thin layer, described acoustical cotton is between described the first film layer and described second thin layer, described the first film layer is between described acoustical cotton and described PP plate, described acoustical cotton is cotton-shaped, described PP plate is made up of polyethylene and polypropylene, described acoustical cotton is made up of polypropylene and PETG, described door-plate high-efficiency sound-absorbing dividing plate carries out sound-absorbing by utilizing the sound-absorbing effect of described acoustical cotton, described PP plate also has good soundproof effect simultaneously, described door-plate high-efficiency sound-absorbing dividing plate is made to have fabulous sound-absorbing effect by both combinations.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of the door-plate high-efficiency sound-absorbing dividing plate that Fig. 1 provides for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of the utility model protection.
As Fig. 1, the utility model embodiment provides a kind of door-plate high-efficiency sound-absorbing dividing plate, comprises PP plate 1, the first film layer 2, acoustical cotton 3 and the second thin layer 4, the first film layer 2 described in described acoustical cotton 3 and between described second thin layer 4.Described the first film layer 2 is between described acoustical cotton 3 and described PP plate 1, and described acoustical cotton 3 is in cotton-shaped, and described PP plate 1 is made up of polyethylene and polypropylene, and forms the hardboard with flexibility, and described PP plate is black.Described acoustical cotton 3 is made up of polypropylene and PETG, and described second thin layer 4 is covered on described acoustical cotton 3, and described acoustical cotton 3 and described the first film layer 2 and described second thin layer 4 are all in white.
As Fig. 1, between described PP plate 1 and described the first film layer 2, adopt high temperature compound, namely first the first film layer 2 is bonded together with PP plate 1 when temperature is higher, has just been combined with each other each other after cooling.Concrete, described acoustical cotton 3 is in forming process, before this polypropylene and PETG were melted, then by the pore on mould, carry out blowing by hot blast to form, and carry out sandwiched by described the first film layer 2 and described second thin layer 3 to described acoustical cotton 3, and then described the first film layer 2 is carried out compound with the described PP plate prepared, the manufacturing process to described door-plate high-efficiency sound-absorbing dividing plate can be completed.In the process, many described the first film layers 2, make preparation process separately to carry out, after having prepared described acoustical cotton 3 and described PP plate 1 respectively, then carry out both compound working procedures, prepare more simple and convenient.
Further, described door-plate high-efficiency sound-absorbing dividing plate is used for, in the car door of car, effectively to stop the noise outside car door.
