The present invention relates to an acoustic damping material comprising a binder matrix and a filler component, the binder matrix comprising an asphalt component or a polymer component, and the filler component comprising at least one solid particulate cellulose-containing filler. The acoustic damping material is suitable for damping undesirable vibrations and noise in mechanical structures and components of manufactured articles. The invention also relates to the use of an acoustic damping material for vibration and noise damping in transport vehicles and large household appliances, to a vibration and noise damping element comprising a damping layer consisting of an acoustic damping material, to a method for applying a vibration and noise damping element to a noise emitting surface of a substrate, and to a vibration damping system, a vibration and noise damping component includes a substrate and a vibration and noise damping element bonded to a noise emitting surface of the substrate.
本发明涉及包含粘合剂基质和填料组分的声阻尼材料,所述粘合剂基质包含沥青组分或聚合物组分,和所述填料组分包含至少一种固体颗粒状含纤维素填料。声阻尼材料适于用于在制造制品的机械结构和部件中不期望的振动和噪声的阻尼。本发明还涉及声阻尼材料用于运输车辆和大型家电中振动和噪声阻尼的用途,涉及包含由声阻尼材料组成的阻尼层的振动和噪声阻尼元件,涉及施加振动和噪声阻尼元件至基材的噪声发射表面的方法,并涉及振动阻尼系统,其包含基材和与基材的噪声发射表面结合的振动和噪声阻尼元件。
