Abstract
The utility model relates to a sound baffle is inhaled to high efficiency, include the PP board, inhale sound cotton and thin layer, it is located to inhale the sound cotton the PP board with between the thin layer, 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, the film laminating cover in inhale on the sound cotton. Sound baffle is inhaled to 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 high efficiency has fabulous absorbing effect.
Description
Technical field
The utility model relates to a kind of 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 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 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 high-efficiency sound-absorbing dividing plate, comprise PP plate, acoustical cotton and thin layer, described acoustical cotton is between described PP plate and described thin layer, 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, and described thin layer is covered on described acoustical cotton.
Further, high temperature compound is adopted between described PP plate and described acoustical cotton.
Further, described high-efficiency sound-absorbing dividing plate is used in the car door of car.
Further, the thickness of described high-efficiency sound-absorbing dividing plate is 4-6mm.
Further, described thin layer is identical with the composition of described acoustical cotton.
Further, described 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:
Described high-efficiency sound-absorbing dividing plate comprises PP plate, acoustical cotton and thin layer, described acoustical cotton is between described PP plate and described thin layer, 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 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, makes described high-efficiency sound-absorbing dividing plate 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 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 high-efficiency sound-absorbing dividing plate, comprises PP plate 1, acoustical cotton 2 and thin layer 3, and described acoustical cotton 2 is between described PP plate 1 and described thin layer 3.Described acoustical cotton 2 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 2 is made up of polypropylene and PETG, and described thin layer 3 is covered on described acoustical cotton 2, and described acoustical cotton 2 and described thin layer 3 are all in white.
Further, between described PP plate 1 and described acoustical cotton 2, adopt high temperature compound, namely first acoustical cotton 2 is bonded together with PP plate 1 when temperature is higher, has just been combined with each other each other after cooling.Polypropylene and PETG, in forming process, melted, and then by the pore on mould, carried out blowing form by hot blast, and be molded on cold PP plate 1, thus both are combined with each other by described acoustical cotton 2 before this.
Further, described high-efficiency sound-absorbing dividing plate is used for, in the car door of car, effectively to stop the noise outside car door.
Further, the thickness of described high-efficiency sound-absorbing dividing plate is 4-6mm, and the space that it is accounted for is less, is applicable to the microminiaturization of product.
Further, described thin layer 3 is identical with the composition of described acoustical cotton 2, is directly formed by mould blowing.Described thin layer 3 has multiple equally distributed micropore.
Further, the density of described acoustical cotton 2 is 50g/m
2-600g/m
2.
In sum, described high-efficiency sound-absorbing dividing plate carries out sound-absorbing by utilizing the sound-absorbing effect of described acoustical cotton 2, and described PP plate 1 also has good soundproof effect simultaneously, makes described high-efficiency sound-absorbing dividing plate have fabulous sound-absorbing effect by both combinations.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
