摘要
为开发在中高频和宽频范围内具有优异吸声性能的汽车吸声非织造材料,添加RGO,并将静电纺丝技术和双组分熔喷非织造技术有效结合,制备出RGO/PAN纳米纤维膜/双组分熔喷非织造材料。采用SEM、TG、XRD、表面电阻、吸声系数对制备的非织造材料性能进行表征,研究是否添加RGO以及不同添加量对RGO/PAN纳米纤维膜/双组分熔喷非织造材料性能的影响。结果表明:RGO/PAN纳米纤维膜/双组分熔喷非织造材料中存在RGO;添加RGO后改善了双组分熔喷非织造材料的热稳定性能和抗静电性能,当RGO质量分数为3%时,抗静电性能最好;在500~6 300 Hz范围内,添加RGO后,双组分熔喷非织造材料吸声性能的改善较为显著,最大增幅为24%。
In order to develop automotive sound-absorbing nonwovens with excellent sound-adsorbing properties in mid-high frequency and wide frequency range,adding RGO,RGO/PAN nanofibers/bi-component melt-blown nonwovens are prepared by combining electrospinning technology with bi-component melt-blown nonwovens technology.SEM,TG,XHD,Raman,surface resistance and sound ahsorption coefficient are used to characterize RGO/PAN nanofiber film/bi-component melt-blown nonwovens.The effects of RGO and different amount of RGO on the properties of RGO/PAN nanofiher film/bi-component melt-blown nonwovens are studied.The results show that KGO is existed in RGO/PAN nanofiber membrane/bi-component mell-blown nonwovens;the thermal stability of bi-component melt-blown nonwovens improves by adding RGO;the antistatic property of bi-component melt-blown nonwovens improves by adding KGO;and the sound absorption property of hi-component melt-blown nonwovens improves remarkably when KGO is added in the range of 500?6300 Hz.The maximum increase is 24%and increases with the increase of KGO content,hut the increase rate of sound absorption coefficient begins to decrease with the increase of RGO content.
