Damping sheet

The utility model provides a damping sheet. Specifically, the damping sheet comprises, in order: a polymer elastomer damping layer; a first pressure-sensitive adhesive layer; and a hot melt film layer. According to the technical scheme, the damping sheet has a high damping loss factor, particularly has good high-temperature adhesion (thermal deformation), can deform like an asphalt material at the high temperature (for example, 120-180 DEG C) so as to be attached to the surface of a base material (for example, metal) with a complex shape, and has the advantages of being simple in structure and convenient to use. The novel damping sheet is suitable for replacing an asphalt material to serve as a novel damping sheet in the industries of automobiles, rail transit, buildings and electric appliances under the condition that the operation process does not need to be changed. 本实用新型提供一种阻尼片材。具体地，所述阻尼片材依次包括：聚合物弹性体阻尼层；第一压敏胶层；和热熔膜层。根据本实用新型的技术方案的阻尼片材具有较高的阻尼损耗因子，并且特别地，具有良好的高温贴附性(热变形性)，能够在高温(例如，120-180℃)下像沥青材料一样变形以贴附到具有复杂形状
