摘要
从聚合物吸声材料和隔声材料两方面入手,简要介绍了多孔吸声材料、多层吸声材料、复合多孔吸声材料,单层隔声材料以及多层隔声材料的作用机理;基于现有材料性能的局限性,综述聚合物复合降噪材料的制备方法和提高降噪性能的途径;此外,结合文献介绍了层状复合降噪材料、环保型复合降噪材料和声学超材料的制备及声学特性研究进展,为今后降噪聚合物材料的研究提供了方向;最后,简要展望了高降噪复合材料的发展前景。
In this paper,the action mechanisms of porous sound absorbing materials,multi-layered sound absorbing materials,composite porous sound absorbing materials,single-layered sound insulating materials and multi-layered sound insulating materials were briefly introduced from the aspects of polymeric sound absorbing materials and sound insulating materials.Based on the limitations of the performance of existing materials,the preparation methods of polymeric composite soundproofing materials and the ways to improve their soundproofing performance were reviewed in detail.Moreover,through combining with the literature,the preparation methods and acoustic properties of layered composite noisereducing materials,environmentally friendly composite noise-reducing materials,and acoustic metamaterials were introduced to provide a direction for the future improvement of noise-reducing polymeric materials.Finally,a brief outlook on the development prospects of high-noise composite materials was presented.
