Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
As shown in Figure 1 to Figure 3, the embodiment of the invention provides a kind of automobile front wall sound-isolation pads comprising ontology 100, this
Avoid holes 600 are provided on body 100；Ontology 100 includes two-component cotton layer 30, PU layer 10 and EVA layer 20, and the setting of EVA layer 20 exists
Between two-component cotton 30 and PU of layer layer 10.
Wherein, by setting avoid holes 600 can to avoid the sound insulating pad during installation on front wall metal plate protrusion or add
Strengthening tendons interfere；In addition, it should be noted that, in the prior art, pet layer is usually set in firewall assembly, but it is big
The use of amount pet layer can generate larger weight, while the soundproof effect of pet layer is poor, and long-time service can harden.Therefore, exist
A kind of sound insulating pad being bonded by two-component cotton layer 30, PU layer 10 and EVA layer 20 is present embodiments provided, difference can be passed through
Material layer realize effective absorption to noise, while the weight of sound insulating pad can be substantially reduced；Wherein, the addition of PU layer 10 can
So that the sound insulating pad light soft, and the use of EVA layer 20 can promote the durability of sound insulating pad, and two-component cotton layer 30 can be with
The sound absorbing power of sound insulating pad is promoted, while the form of the sound insulating pad can be kept, prevents from deforming after being used for a long time.Meanwhile relatively
For the prior art, as shown in figure 3, automobile front wall sound-isolation pad provided in an embodiment of the present invention compared with the existing technology in it is anti-
