Further, the thickness of the PU layer is thicker than the thickness of the first nonwoven fabric layer and the thickness of the PU film.

Further, the method also comprises the following steps: the second non-woven fabrics layer sets up the PU membrane is kept away from a side of PU layer.

Furthermore, one side of the PU layer is kept away from on the first non-woven fabric layer and/or one side of the PU membrane is kept away from on the second non-woven fabric layer is provided with an anti-oxidation layer.

Furthermore, a first adhesive layer is arranged between the first non-woven fabric layer and the PU layer.

Furthermore, a second adhesive layer is arranged between the second non-woven fabric layer and the PU film.

Further, the first non-woven fabric layer is kept away from one side of PU layer or the second non-woven fabric layer is kept away from one side of PU membrane is equipped with the XPE material layer.

The utility model has the advantages that: be different from prior art's condition, the utility model discloses a enclose interior plate body before car is including hugging closely first non-woven fabrics layer, PU layer and the PU membrane together in proper order, wherein the PU layer comprises the PU material that the density scope was repaiied at 90-110 kg/m. In this way, the utility model discloses a before car enclose the inner plate body have good sound effect of inhaling that gives sound, compare that traditional car of constituteing by the film material before enclose the weight of inner plate body lighter, and compare that traditional car of constituteing by the film material before enclose the manufacturing cost of inner plate body lower, promoted user's experience greatly.

Detailed Description

Referring to fig. 1, fig. 1 is a schematic structural view of a front wall inner plate of an automobile according to the present invention. The automobile front wall inner plate body comprises a first non-woven fabric layer 11, a PU layer 12, a PU film 13 and a second non-woven fabric layer 14 which are sequentially attached together.

In this embodiment, PU layer 12 has light in weight and gives sound insulation and inhale the characteristics that the sound effect is good, compare and enclose the inner panel body before the car of constituteing by the film material on the market, the PU material of this embodiment is lighter than the film material, make before this car enclose the inner panel body before traditional car enclose the weight of inner panel lighter, and the PU material is more common material on the market, the price is also cheaper relatively, light PU material is cheaper than the film material promptly, can make before this car enclose the manufacturing cost of inner panel body low, accord with new energy automobile manufacturing condition, user's experience has been promoted greatly.

In this embodiment, PU layer 12 is comprised of PU material having a density in the range of 90-110kg/m for carrying out a thin film transformation. Preferably, PU layer 12 is comprised of PU material having a density of 100kg/m of labor. It is understood that PU layers comprising PU materials having densities in the range of 90-110kg/m were flash-polished lighter than conventional PU materials.

It is to be understood that the second nonwoven layer 14 is disposed on the side of the PU film 13 remote from the PU layer 12. In the present embodiment, the thickness of the PU layer 12 is thicker than the thickness of the first nonwoven fabric layer 11, the PU film 13, and the second nonwoven fabric layer 14. Preferably, the thicknesses of the first nonwoven fabric layer 11 and the second nonwoven fabric layer 14 are equal, and the thickness of the first nonwoven fabric layer 11 is greater than the thickness of the PU film 13.

In this embodiment, the first nonwoven fabric layer 11 and the second nonwoven fabric layer 14 have the waterproof and oilproof effect, so that the waterproof and oilproof effect of the inner panel body of the front wall of the automobile is good.

It should be understood that in other embodiments, a first adhesive layer is disposed between the first nonwoven fabric layer 11 and the PU layer 12 to increase the connection between the first nonwoven fabric layer 11 and the PU layer 12.

It should be understood that in other embodiments, a second adhesive layer is disposed between the second nonwoven layer 14 and the PU film 13 to enlarge the connection between the second nonwoven layer 14 and the PU film 13.

Further, in other embodiments, the side of the first nonwoven fabric layer 11 away from the PU layer 12 and/or the side of the second nonwoven fabric layer 14 away from the PU film 13 is provided with an oxidation resistant layer to provide oxidation resistance.

Further, in other embodiments, the side of the first nonwoven layer 11 facing away from the PU layer 12 or the side of the second nonwoven layer 14 facing away from the PU film 13 is provided with a layer of XPE material. It will be appreciated that the XPE material has a higher tensile strength and finer cells than the EPE material to further enhance the sound insulating and absorbing effect. In addition, the XPE material also has the characteristics of difficult decomposition, no odor and good elasticity.

It should be understood that in other embodiments, the PU layer 12 is provided with a plurality of spiral long holes at intervals, which can reduce the weight on one hand and increase the sound insulation and absorption effects on the other hand. Further, PU layer 12 is provided with a plurality of spiral helicine first archs towards a side interval of first non-woven fabrics layer 11, can increase PU layer 12 and first non-woven fabrics layer 11's the dynamics of being connected like this, can also increase area of contact between them simultaneously for connect stably.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
