Abstract
The utility model proposes a kind of sound-absorbing Sound-proof automotive carpet, including superficial layer, sound absorbing layer, re-coating layer and bottom surface layer, superficial layer, sound absorbing layer, re-coating layer and bottom surface layer are stacked from top to bottom successively, packed layer is provided between superficial layer and sound absorbing layer, packed layer is PE powder beds, and superficial layer is PET needle-punching with napping fabrics, and sound absorbing layer is PET needled fabrics, re-coating layer is EVA material, and bottom surface layer is non-woven fabrics.The utility model increases PE powder packed layers between superficial layer, sound absorbing layer, substantially increase compared to simple carpet surface sound-absorbing audio, on the basis of conventional re-coating layer sound insulation, excellent sound absorption qualities are added, meanwhile, PET needle-punching with napping fabric and PET needled fabrics used in superficial layer and sound absorbing layer are porous structural, improve sound-absorbing effect, superficial layer is PET needle-punching with napping fabrics, with excellent fine hair sense, substantially increases the comfortableness and sight of product.
Description
Technical field
The utility model is related to technical field of automotive upholstery, and in particular to a kind of sound-absorbing Sound-proof automotive carpet.
Background technology
With developing rapidly for Domestic Automotive Industry, people also pay attention in again for the acoustical behavior of automobile.Car engine
These noise sources of machine, transmission system and gas extraction system are directly connected to car floor, during running car, and what these parts were produced makes an uproar
Sound can be passed directly to in-car by bottom plate, form noise pollution in the car, influence the comfort level of passenger inside the vehicle.
Because the carpet that pass-by noise source is mainly passed in in-car, therefore automobile bodies by car floor is that reduction is in-car
Noise most direct and effective part.Existing car carpeting is generally divided into two kinds：1st, it is pouring in the middle of PET needled fabrics and bottom felt
PE film plays decoration and deadening, and its is cheap, but with regard to PE film, soundproof effect is poor；2nd, it is PET acupunctures
Coating is aggravated between fabric and bottom felt, soundproof effect is fine, but product weight is high, cost is high, also not meeting automobile light weight will
Ask.
Therefore, in view of the above-mentioned problems, the utility model proposes a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide the soundproof effect and sound absorption qualities of a kind of increase main carpet of automotive interior, meets
The requirement of automobile light weight, comfortableness and the sound-absorbing Sound-proof automotive carpet of security that raising automobile is used.
The utility model is achieved through the following technical solutions：
A kind of sound-absorbing Sound-proof automotive carpet, including superficial layer, sound absorbing layer, re-coating layer and bottom surface layer, the superficial layer, sound-absorbing
Layer, re-coating layer and bottom surface layer are stacked from top to bottom successively, and packed layer is provided between the superficial layer and sound absorbing layer, described to fill out
Layer is filled for PE powder beds, the superficial layer is PET needle-punching with napping fabrics, the sound absorbing layer is PET needled fabrics, the re-coating layer
For EVA material, the bottom surface layer is non-woven fabrics.
Further, the PET needle-punching with napping fabric and PET needled fabrics used in the superficial layer and sound absorbing layer are porous
Type structure.
Further, the thickness of the packed layer is 0.5 ~ 1.5mm.
The beneficial effects of the utility model are：The utility model increases PE powder packed layers between superficial layer, sound absorbing layer,
Substantially increase compared to simple carpet surface sound-absorbing audio, on the basis of conventional re-coating layer sound insulation, add excellent sound absorption properties
Can, meanwhile, PET needle-punching with napping fabric and PET needled fabrics used in superficial layer and sound absorbing layer are porous structural, are improved
Sound-absorbing effect, superficial layer is PET needle-punching with napping fabrics, with excellent fine hair sense, substantially increases comfortableness and the sight of product
Reward property.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1st, superficial layer, 2, packed layer, 3, sound absorbing layer, 4, re-coating layer, 5, bottom surface layer.
Embodiment
Illustrate to be described further the utility model below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of sound-absorbing Sound-proof automotive carpet, including superficial layer 1, sound absorbing layer 3, re-coating layer 4 and bottom surface layer 5,
Superficial layer 1, sound absorbing layer 3, re-coating layer 4 and bottom surface layer 5 are stacked from top to bottom successively, are provided between superficial layer 1 and sound absorbing layer 3
Packed layer 2, packed layer 2 is PE powder beds, and superficial layer 1 is PET needle-punching with napping fabrics, and sound absorbing layer 3 is PET needled fabrics, recoating
Layer 4 is EVA material, and bottom surface layer 5 is non-woven fabrics.PET needle-punching with napping fabric and PET acupuncture faces used in superficial layer 1 and sound absorbing layer 2
Material is porous structural, and the thickness of packed layer is 0.5 ~ 1.5mm.
In the present embodiment, PE powder packed layers are increased between superficial layer, sound absorbing layer, compared to simple carpet surface sound-absorbing sound
Effect is remarkably reinforced.On the basis of conventional re-coating layer sound insulation, increase excellent sound absorption qualities again, make product that there are excellent sound absorption properties
There is sound insulation value again while energy, meanwhile, superficial layer and sound absorbing layer material therefor belong to loose structure, and internal chopped fiber is in length and breadth
Staggeredly, porosity is very high, and sound absorption qualities are excellent.Superficial layer uses thin red Buddhist nun's fiber, and is molded by needle-punching with napping
Technique, unnumbered fiber crossovers blend together into countless fine gaps in a jumble, and sound enters just to can't get out, inside fabric
Passage is too bad, and sound left punching right side in communication process is hit, and energy is gradually used up in the process, the purpose of sound-absorbing is reached.Make production
The sound-absorbing effect of product can reach requirement；Meanwhile, superficial layer is fleece fabric, with excellent fuzzy hand, is substantially increased
The comfortableness and sight of product.
It is described above, only it is preferred embodiment of the present utility model, not makees any formal to the utility model
Limitation, although the utility model is disclosed above with preferred embodiment, but is not limited to the utility model, any ripe
Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, according to technical spirit of the present utility model, within spirit of the present utility model and principle, what above example was made appoints
What simple modification, equivalent substitution and improvement etc., still falls within the protection domain of technical solutions of the utility model.
