聚氨酯阻尼材料的研究进展

Research progress of polyurethane damping materials

介绍了聚合物的阻尼机理和阻尼结构,综述了采用不同方法[如物理共混、化学共聚、互穿聚合物网络(IPN)和阻尼结构设计等]对PU(聚氨酯)阻尼材料进行改性的研究进展。最后对PU阻尼材料的发展方向进行了展望。

The damping mechanism and damping structure of polymer were introduced, and the research progress ,which PU（polyurethane） damping materials were modified by different methods[such as physical blending,chemical copolymerization, interpenetrating polymer network （IPN） , and damping structure design], was summarized. Finally, the development direction of PU damping materials was expected.
