Abstract
The utility model provides a sound cotton is inhaled to car, including inhaling the cotton body of sound, inhale the cotton body of sound including melt spout cotton layer and be located respectively melt spout cotton layer about the last non -woven fabrics layer and lower non -woven fabrics layer on two sides, its characterized in that: melting and spouting cotton layer and melted to spout by pp and pet material mixture and form, the below on lower non -woven fabrics layer has set gradually antistatic backing and aluminium foil heat preservation, go up the non -woven fabrics layer, melt spout cotton layer and down the non -woven fabrics layer adopt knurling technology to make to form a plurality of bellied wave structure on inhaling the cotton body of sound, press flower structure to hug closely in the antistatic backing surface for ring type and its, when should inhale the amortization that the sound cotton can be fine, can realize keeping warm and anti - static effect.
Description
Technical field
The utility model relates to a kind of acoustical cotton, more particularly, relates to a kind of automobile acoustical absorption cotton.
Background technology
Along with the fast development of science and technology, automobile more and more becomes the indispensable vehicle, use frequent and general in the extreme, and the material of the absorptive product of automotive interior, mainly based on waste woven felt, is form by the raw material machine up based on cotton of waste and old recovery at present.Its shortcoming is that weight is large, smell is large, Volatile Organic Components is higher, and product easily burns, and sound-absorbing efficiency is also very low, and this causes when running car, and influence of noise is very serious, and the traveling comfort driven and safety also very low.
Utility model content
Based on the problems referred to above, it is cotton that the utility model object is to provide a kind of automobile acoustical absorption, while this acoustical cotton can be good at noise reduction, can realize insulation and anti-static effect.
For above problem, provide following technical scheme: a kind of automobile acoustical absorption is cotton, comprise acoustical cotton body, acoustical cotton body comprises melt-blown cotton layer and lays respectively at the upper nonwoven layer of melt-blown cotton layer upper and lower surface and lower nonwoven layer, it is characterized in that: melt-blown cotton layer mixes melt-blown forming by pp and pet material, the below of lower nonwoven layer is disposed with antistatic backing and foil insulation, upper nonwoven layer, melt-blown cotton layer and lower nonwoven layer adopt embossed technology to make wave structure acoustical cotton body being formed multiple projection, patterned structure is circular ring type and it is close to antistatic backing surface.
The utility model is set to further, and its diameter of the cirque structure of described patterned structure is 6-10cm.
The beneficial effects of the utility model: the patterned structure of circular ring type can make acoustical cotton body forms certain wave structure, and the form of this wave structure has certain stability, not yielding, the effect of filtering noise reduction can be produced, the setting of antistatic backing effectively can prevent the electrostatic that silencing cotton carries, patterned structure there is certain intensity after repressed and can be stable be fixed on antistatic backing surface.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile acoustical absorption cotton in the utility model embodiment:
Fig. 2 is the structural representation of the cotton cutaway view of automobile acoustical absorption in the utility model embodiment.
Number in the figure implication: 1-acoustical cotton body; The upper nonwoven layer of 11-; Nonwoven layer under 12-; The melt-blown cotton layer of 13-; 14-antistatic backing; 15-foil insulation; 16-patterned structure; 2-wave structure.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figures 1 and 2, a kind of automobile acoustical absorption is cotton, comprise acoustical cotton body 1, acoustical cotton body 1 comprises melt-blown cotton layer 13 and lays respectively at the upper nonwoven layer 11 of melt-blown cotton layer 13 upper and lower surface and lower nonwoven layer 12, melt-blown cotton layer 13 mixes melt-blown forming by pp and pet material, the below of lower nonwoven layer 12 is disposed with antistatic backing 14 and foil insulation 15, upper nonwoven layer 11, melt-blown cotton layer 13 and lower nonwoven layer 12 adopt embossed technology to make melt-blown cotton layer 13 form the wave structure 2 of multiple projection, after embossing, upper nonwoven layer 11 is close to lower nonwoven layer 12, wave structure 16 is for circular ring type and it is close to antistatic backing 14 surface.Its diameter of cirque structure of the present embodiment Wave structure 16 is 6-10cm.The wave structure 16 of circular ring type can make acoustical cotton body 1 to be formed certain wave structure 2, and the form of this wave structure 2 has certain stability, not yielding, the effect of filtering noise reduction can be produced, the setting of antistatic backing 14 effectively can prevent the electrostatic that silencing cotton carries, wave structure 16 there is certain intensity after repressed and can be stable be fixed on antistatic backing 14 surface.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
Claims (2)
1. an automobile acoustical absorption cotton, comprise acoustical cotton body, acoustical cotton body comprises melt-blown cotton layer and lays respectively at the upper nonwoven layer of melt-blown cotton layer upper and lower surface and lower nonwoven layer, it is characterized in that: melt-blown cotton layer mixes melt-blown forming by pp and pet material, the below of lower nonwoven layer is disposed with antistatic backing and foil insulation, upper nonwoven layer, melt-blown cotton layer and lower nonwoven layer adopt embossed technology to make wave structure acoustical cotton body being formed multiple projection, and patterned structure is circular ring type and it is close to antistatic backing surface.
2. a kind of automobile acoustical absorption according to claim 1 is cotton, it is characterized in that: its diameter of the cirque structure of described patterned structure is 6-10cm.
