摘要/Abstract

摘要： 用十六烷基三甲基溴化铵(CTAB)对蒙脱土进行有机化处理,以过硫酸铵为引发剂,使丙烯腈单体在有机化蒙脱土层间进行原位聚合.对这种插层复合材料的的燃烧性能和热性能进行了初步研究,并且用红外光谱和X射线衍射对其结构进行了分析与表征.结果表明:PAN/MMT共混复合物的阻燃性能有一定提高,其极限氧指数从18%提高到了22%;耐热性能得到一定程度改善.红外光谱和X射线衍射分析结果显示:在蒙脱土片层之间通过原位聚合生成了聚丙烯腈大分子,使蒙脱土层间距有一定程度的增大.

Abstract: Organized montmorillonite(O-MMT) was prepared using cetyl trimethyl ammonium bromide(CTAB). With ammonium persulfate as the initiator, Polyacrylonitrile (PAN) was made by in situ polymerization between the layer of O-MMT. The structure of PAN/MMT was characterized by Fourier transformed infrared spectroscopy (FT-IR) and X-ray diffractometry (XRD). Both the flame retardant property and heat resistanct were investigated. FT-IR and XRD indicated that the interlay spacing of MMT has been expanded, which was attributed to the fact that PAN has been intercalated into the layer by in situ polymerization. The LOI of the blend was enhanced from 18% to 22%, which revealed that the flame retardant property has been improved. In addition, the heat resistanct has been improved.
