摘要
以高聚物的吸声机理为切入点,综述了聚氨酯水声吸声材料的研究现状和进展,其中重点阐述了传统聚氨酯链结构与聚集态结构对能量损耗的影响机制,以及聚氨酯吸声材料的共混、共聚、互穿网络、增加填料等改性方法的研究与应用,并对其未来的发展趋势进行了展望。
The mechanisms of acoustic absorption of polymer were introduced,and the research progress and status of polyurethane underwater acoustic absorption materials were summarized.The effect of chain and aggregation structures on energy loss,modification and application of polyurethane acoustic absorption materials including blend,copolymerization,interpenetrating polymer networks,and filler were expatiated.Finally,the development directions of polyurethane underwater acoustic absorption material were pointed.
