The invention discloses a lightweight sound-absorbing cotton composite material with strong sound insulation and noise reduction as well as a preparation method and application thereof, sound-absorbing cotton and a plastic film or a rubber and plastic damping film are bonded through glue and then are subjected to rolling bonding, then are fed into a drying tunnel to be dried and cured, and finally are rolled to obtain the sound-absorbing cotton composite material. The sound-absorbing cotton composite material is used for sealing a cabin or an automobile interior trim part. By means of the mode, the sound absorption and noise reduction effects are achieved, the strong sound insulation effect of noise reflection and damping vibration attenuation and noise reduction is achieved, the advantages of being low in density, low in cost and easy to manufacture are achieved, and the noise reduction effect is better when the sound absorption and noise reduction composite material is used in a closed cabin or an automobile interior.

    本发明公开了轻量化强隔音降噪的吸音棉复合材料及其制备方法和应用,将吸音棉与塑料薄膜或橡塑阻尼薄膜通过胶水粘合后滚压粘接,接着送入烘道内烘干固化,最后收卷获得吸音棉复合材料,上述吸音棉复合材料用于封闭舱室或者汽车内饰件。通过上述方式,本发明具有吸声降噪的效果,还具有将噪声反射、阻尼减振降噪的强隔声效果,具有密度轻量化、成本低和制造容易的优点,用在封闭舱室或汽车内饰中降噪效果更佳。
