摘要
为缓解我国汽车内饰用黄麻吸声板产量缩减的现状,研究棕榈纤维毡/3-羟基丁酸酯和3-羟基戊酸酯共聚物(即PHBV)/陶粒热压制备吸声板的低频平均吸声系数、拉伸性能、拉伸断面形貌、红外光谱等性能,并与市场上常用的黄麻纤维毡/PHBV热压吸声板、黄麻纤维毡/聚丙烯热压吸声板进行对比。结果表明:棕榈纤维毡/PHBV/陶粒热压吸声板的低频平均吸声系数为0.66,高于黄麻吸声板;拉伸强度低于黄麻吸声板,拉伸断面形貌和红外光谱与黄麻相似,可部分替代黄麻制备汽车内饰用吸声材料。
In order to alleviate the current production reduction of jute sound absorbing board for automotive interior in China,the low frequency average sound absorbing coefficient,tensile properties,tensile section morphology and infrared spectra of the sound absorbing board prepared by hot pressing of palm fiber felt/3-hydroxybutyrate and 3-hydroxyvalerate copolymer(i.e,PHBV)/ceramide were studied.It was compared with jute fiber felt/PHBV thermocompression sound absorption board and jute fiber felt/polypropylene thermocompression sound absorption board commonly used in the market,The results showed that the average low-frequency sound absorption coefficient of the palm fiber felt/PHBV/ceramic panel was 0.66,which was higher than that of the jute panel.The tensile strength was lower than that of jute sound absorbing board,and the tensile section morphology and infrared spectrum were similar to jute,which could partially replace jute in the preparation of automotive interior sound absorbing materials.
