Description

A kind of wheel cover of automobile sound-absorbing pad
Technical field
This utility model relates to automotive trim production field, particularly to a kind of wheel cover of automobile sound-absorbing pad.
Background technology
Along with progress and people's level of consumption of society improve constantly, client is for automobile acoustical absorption sound insulation, lightweight, comfortable Also requiring that of the aspects such as degree is more and more higher.Wheel cover of automobile sound-absorbing pad is mounted on wheel cover of automobile, can effectively reduce making an uproar of automobile Sound.At present, wheel cover sound-absorbing pad many employings PET/PP double-component acoustical cotton on the market, absorbing sound and lowering noise effect is limited.Meanwhile, PET gathers Ester fiber is chemical synthetic fiber fusing point high (more than 250 DEG C), degraded difficulty, and therefore, give up in PET/PP double-component acoustical cotton corner Material reclaims difficulty.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of wheel cover of automobile sound-absorbing pad, is effectively improved sound-absorbing pad Sound insulation and noise reduction, can reduce goods processing temperature simultaneously, and leftover bits easily reclaim, easy to process, improve production Efficiency, can be ornamental strong.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of wheel cover of automobile sound-absorbing pad, including first Polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, the second acid fiber by polylactic layer and the second polypropylene fibre layer, described First polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, the second acid fiber by polylactic layer and the second polypropylene fibre layer by Stack gradually layout down.
The beneficial effects of the utility model are: the first polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, second Acid fiber by polylactic layer and the second polypropylene fibre layer, be effectively improved sound insulation and the noise reduction of sound-absorbing pad;Acid fiber by polylactic is with poly- The processing temperature of tacryl is close, it is possible to reduce goods processing temperature;Acid fiber by polylactic is biodegradable, and leftover bits are easy Reclaim, easy to process, improve production efficiency, can be ornamental strong.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described mixed layer is made up of acid fiber by polylactic and polypropylene fibre, acid fiber by polylactic and polypropylene fibre Mixed proportion be 1:1.
Above-mentioned further scheme is used to provide the benefit that: the processing temperature of acid fiber by polylactic and polypropylene fibre is close, Goods processing temperature can be reduced.
Further, described first polypropylene fibre layer and the second polypropylene fibre layer are spunbond fabric by polypropylene fibre Become.
Further, described first polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, the second acid fiber by polylactic layer It is 19~21mm with the thickness of the second polypropylene fibre layer stackup.
Further, the thickness of described mixed layer is 9~11mm;First acid fiber by polylactic layer and the second acid fiber by polylactic layer Thickness is 4~5mm;The thickness of the first polypropylene fibre layer and the second polypropylene fibre layer is 0.4~0.6mm.
Further, described first polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, the second acid fiber by polylactic layer With second is bonding by PUR between polypropylene fibre layer, and by hot-pressing, edge-sealing molding.
Above-mentioned further scheme is used to provide the benefit that: processing is simple, convenient, improves production efficiency, can be ornamental By force.
