Description
Technical field
The utility model relates to a kind of non-woven fabrics more particularly to a kind of new automobile non-woven fabrics.
Background technique
Non-woven fabrics is environment-friendly materials of new generation, has moisture-proof, ventilative, flexible, light, not combustion-supporting, easy decomposition, nontoxic nothing
Irritation, it is rich in color, cheap, recyclable the features such as.As the improvement of people's living standards, development of automobile of riding instead of walk
Rapidly, purposes of the non-woven fabrics on automobile is also more and more extensive.Automobile engine is the heart of automobile, is an energy conversion machine
Structure, it is by gasoline or the thermal energy of diesel oil or natural gas, by pushing piston acting, turning in blanket gas in-cylinder combustion gas expansion
Become mechanical energy and provide power for automobile traveling, therefore engine is easy to produce noise at work, while can also generate heat, and needs
Sound-insulating and heat-insulating is carried out to engine, but existing non-woven fabrics sound insulation, heat insulation are poor at present, it is difficult to meet the needs of market.
Utility model content
In order to solve shortcoming present in above-mentioned technology, the utility model provides a kind of new automobile non-woven fabrics.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of new automobile non-woven fabrics, packet

Side；Non-woven substrate includes nonwoven layer A, metal foil layer, nonwoven layer B；Nonwoven layer B is located at the lower section of nonwoven layer A, gold
Belong to layers of foil to be folded among nonwoven layer A and nonwoven layer B；The lower end surface of nonwoven layer B is provided with the hemispherical being recessed upwards
Groove A, hemispherical groove A be it is multiple, multiple hemispherical groove A are equidistantly spaced setting；
Sound absorbing layer includes semi-solid preparation cotton layer, polypropylene acoustical cotton layer；The upper surface of polypropylene acoustical cotton layer is provided with downwards
The hemispherical groove B of recess, hemispherical groove B be it is multiple, multiple hemispherical groove B are equidistantly spaced setting；Polypropylene sound-absorbing
Cotton layer is symmetrically disposed on upper end, the lower end of semi-solid preparation cotton layer；
Vertically offer through-hole on semi-solid preparation cotton layer, through-hole be it is multiple, multiple through-holes are equidistantly spaced setting, multiple through-holes
Inside it is filled with acoustical cotton.
Hemispherical groove A is staggered with hemispherical groove B.
Metal foil layer is copper foil or aluminium foil.
Metal foil layer with a thickness of 0.03-0.1mm.
The setting of the utility model non-woven fabrics metal foil layer enables non-woven fabrics effectively blocking radiant heat, non-woven fabrics tool
There is better heat insulation；The setting of sound absorbing layer can be realized triple sound-absorbings so that non-woven fabrics has very strong sound absorption function, every
Audio fruit is good, long service life, good economy performance, can satisfy demand of the market to automobile non-woven fabrics.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, nonwoven layer A；2, metal foil layer；3, nonwoven layer B；4, hemispherical groove A；5, polypropylene acoustical cotton
Layer；6, hemispherical groove B；7, semi-solid preparation cotton layer；8, through-hole；9, acoustical cotton.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, a kind of new automobile non-woven fabrics, including non-woven substrate, sound absorbing layer；Non-woven substrate is two,
Two non-woven substrates are symmetrically disposed on the top of sound absorbing layer, lower section；Non-woven substrate include nonwoven layer A1, metal foil layer 2,
Nonwoven layer B3；Nonwoven layer B3 is located at the lower section of nonwoven layer A1, and metal foil layer 2 is folded in nonwoven layer A1 and nonwoven layer
Among B3, by needling shape at non-woven substrate.Metal foil layer 2 be copper foil or aluminium foil, metal foil layer 2 with a thickness of 0.03-
0.1mm, can reduce production cost, and economy is more preferable.The setting of metal foil layer 2 compensates for nonwoven layer pull resistance, morphotropism
Present on it is insufficient, enhance the pull resistance of nonwoven layer, so that non-woven substrate is less prone to drawing crack breakage, service life is more
It is long；Metal foil layer 2 can also effectively blocking radiant heat, make non-woven fabrics that there is better heat insulation.
The lower end surface of nonwoven layer B3 is provided with the hemispherical groove A4 being recessed upwards, hemispherical groove A4 be it is multiple, it is more
A hemispherical groove A is equidistantly spaced setting；
Sound absorbing layer includes 7, polypropylene acoustical cotton layer 5 of semi-solid preparation cotton layer；The upper surface of polypropylene acoustical cotton layer 5 be provided with to
The hemispherical groove B6 of lower recess, hemispherical groove B6 be it is multiple, multiple hemispherical groove B are equidistantly spaced setting, hemispherical
Groove B6 is staggered with hemispherical groove A4.
Polypropylene acoustical cotton layer 5 is symmetrically disposed on the upper end of semi-solid preparation cotton layer 7, lower end, and polypropylene acoustical cotton layer 5 plays
Preliminary sound absorption；The setting of hemispherical groove B6 and hemispherical groove A4 is so that nonwoven layer B3 and polypropylene acoustical cotton layer 5
Between there are multiple tiny cavitys, help to further strengthen sound-absorbing effect.
