摘要/Abstract

摘要： 本文采用分散复合融喷技术分别制得了PET/PP分散复合熔喷材料和羽毛/PP分散复合熔喷非织造材，研究了材料厚度、面密度、熔喷纤维平均直径对其吸引系数的影响，结果表明：吸声系数随着厚度的增加而增加；面密度对吸声系数影响较小，随着面密度的增加，样品的吸声系数也有所增加，但增幅较小；熔喷纤维平均直径在1.7~2.4μm内变化时对吸音系数无显著影响。另外，本文还进一步选用3M公司吸音产品和传统废纺毡吸引材料，对比分析了4种材料的吸音性能，结果表明：PET/PP分散复合熔喷吸音材料的吸音性能接近3M公司产品，而且其吸音性能优于传统车用废纺毡吸音材料及羽毛/PP分散复合熔喷非织造材料。

Abstract: In this paper, PET/PP and feather fibers/PP scattered composite melt-blown material were made by scattered composite melt-blown process, respectively. The influences of the thickness, basis density and average fiber diameter on the sound-absorbing property of the materials were studied. It is found that the sound absorption coefficient increases with the increase of the thickness. The influence of basis density on the absorption coefficient is not as obvious as the thickness. The average melt-blown fiber diameter in 1.7~2.4μm has no obvious impact on the absorption coefficient. In addition, the sound-absorbing material made by 3M and the traditional waste fiber sound-absorbing material were selected to compare the sound-absorbing property. It indicates that the sound-absorbing coefficient of PET/PP scattered composite melt-blown sound-absorbing material is similar to 3M Company's product, which is better than the traditional waste fiber sound-absorbing material and feather fibers/PP scattered composite melt-blown nonwoven material

Key words: scattered composite, melt-blown, sound-absorbing material, sound absorption coefficient
