A kind of wheel cover of automobile sound-absorbing pad
Technical field
The present invention 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, light Also requiring that of the aspects such as quantization, comfort level is more and more higher.Wheel cover of automobile sound-absorbing pad is mounted in wheel cover of automobile On, can effectively reduce the noise of automobile.At present, the double group of wheel cover sound-absorbing pad many employings PET/PP on the market Part acoustical cotton, absorbing sound and lowering noise effect is limited.Meanwhile, PET polyester fiber is that chemical synthetic fiber fusing point is high (more than 250 DEG C), degraded difficulty, therefore, PET/PP double-component acoustical cotton leftover bits reclaim difficulty.
Summary of the invention
The technical problem to be solved is to provide a kind of wheel cover of automobile sound-absorbing pad, is effectively improved sound-absorbing The sound insulation of pad and noise reduction, can reduce goods processing temperature simultaneously, and leftover bits easily reclaim, and add Work is convenient, improves production efficiency, can be ornamental strong.
The technical scheme is that 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 second Polypropylene fibre layer, described 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 from top to bottom stack gradually layout.
The invention has the beneficial effects as follows: 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 effect of sound-absorbing pad Really；The processing temperature of acid fiber by polylactic and polypropylene fibre is close, it is possible to reduce goods processing temperature；Poly- Acid fiber is biodegradable, and leftover bits easily reclaim, easy to process, improves production efficiency, can Ornamental strong.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described mixed layer is made up of acid fiber by polylactic and polypropylene fibre, and acid fiber by polylactic is with poly- The mixed proportion of tacryl is 1:1.
Above-mentioned further scheme is used to provide the benefit that: the processing temperature of acid fiber by polylactic and polypropylene fibre Spend close, it is possible to reduce goods processing temperature.
Further, described first polypropylene fibre layer and the second polypropylene fibre layer are spun by polypropylene fibre Sticky cloth is made.
Further, described first polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, second gather The thickness of acid fiber layer and the second polypropylene fibre layer stackup is 19～21mm.
Further, the thickness of described mixed layer is 9～11mm；First acid fiber by polylactic layer and the second poly-breast The fibrolaminar thickness of acid is 4～5mm；First polypropylene fibre layer and the thickness of the second polypropylene fibre layer It is 0.4～0.6mm.
Further, described first polypropylene fibre layer, the first acid fiber by polylactic layer, mixed layer, second gather Between acid fiber layer and the second polypropylene fibre layer bonding by PUR, and become by hot-pressing, edge-sealing Type.
Above-mentioned further scheme is used to provide the benefit that: processing is simple, convenient, improves production efficiency, Can be ornamental strong.
