Abstract
The utility model discloses a kind of automotive trim composite sound-absorbing cottons, including base and surface layer, Surface mulch forms integral structure in base, base is PET acoustical cottons, surface layer is PET non-woven fabrics, after repeatedly consuming, using sound insulation effect of spunlace non-woven cloth, it is seldom to express the energy come inside acoustical cotton for sound.The utility model passes through two layers of compound mode, combine the excellent sound absorption properties of ultra-fine acoustical cotton and the superior acoustic and intensity of spunlace non-woven cloth, sound-absorbing with sound insulation is combined, in the case where not increasing product weight, absorbs the noise that automobile external transmits significantly.
Description
Technical field
The utility model is related to technical field of automobile parts more particularly to a kind of automotive trim composite sound-absorbing cottons.
Background technology
Common ultra-fine interior trim acoustical cotton is extremely difficult to 14177 LEVEL B's of GMW when grammes per square metre is reduced to 450g/ ㎡
It is required that and sound-absorbing effect can be deteriorated.How in the case where ensureing not increasing product grammes per square metre, make the sound-absorbing of automotive trim acoustical cotton
Effect reaches the problem of optimum efficiency is one important.
Therefore, above-mentioned in order to solve the problems, such as, the utility model has provided a kind of new technical solution.
Utility model content
The purpose of the utility model is to provide it is a kind of it is simple in structure, significantly improve in the case where not increasing product weight
The automotive trim composite sound-absorbing cotton of soundproof effect.
Technical solution is used by the utility model is directed to above-mentioned technological deficiency：
A kind of automotive trim composite sound-absorbing cotton, including base and surface layer, the Surface mulch forms integral type in base
Structure, the base are PET acoustical cottons, and the surface layer is PET non-woven fabrics.
Further, PET non-woven fabrics uses spunlace non-woven cloth.
Further, barrier layer is set between the base and surface layer, and barrier layer is porous structure.
The beneficial effects of the utility model are：The utility model combines ultra-fine acoustical cotton by two layers of compound mode
Excellent sound absorption properties and spunlace non-woven cloth superior acoustic and intensity, sound-absorbing with sound insulation is combined, is not increasing product weight
In the case of amount, the noise that automobile external transmits is absorbed significantly.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description
Fig. 1 is the structure diagram of the utility model.
Wherein：1st, base, 2, surface layer.
Specific embodiment
A kind of automotive trim composite sound-absorbing cotton as shown in Figure 1, including base 1 and surface layer 2, surface layer 2 is covered in base 1
Integral structure is formed, base 1 is PET acoustical cottons, and surface layer 2 is PET non-woven fabrics, and sound is inside acoustical cotton by repeatedly consumption
Afterwards, using sound insulation effect of spunlace non-woven cloth, it is seldom that the energy come can be expressed.
In the present embodiment, PET non-woven fabrics uses spunlace non-woven cloth, and spunlace non-woven cloth surface is compact, relatively common ultra-fine white
Cotton adds cohesion surface again, prevents surface from separating.
In the present embodiment, barrier layer is set between base and surface layer, and barrier layer is porous structure, and soundproof effect is notable.
In the present embodiment, a kind of manufacturing method of automotive trim composite sound-absorbing cotton：Include the following steps：
Process 1：PET fiber through shredding, mixing, combing, lapping, spun lacing, the surface layer 2 rolled is made；
Process 2：Ultra-fine PET fiber forms ultra-fine acoustical cotton through shredding, mixing, combing, lapping, baking, laminating surface layer 2.
The beneficial effects of the utility model are：The utility model combines ultra-fine acoustical cotton by two layers of compound mode
Excellent sound absorption properties and spunlace non-woven cloth superior acoustic and intensity, sound-absorbing with sound insulation is combined, is not increasing product weight
In the case of amount, the noise that automobile external transmits is absorbed significantly.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
