| 摘 要： | 通过离子交换反应将铜离子负载在无机层状蒙脱土上，采用十六烷基三甲基溴化铵对载铜蒙脱土进行有机改性，并将其作为阻燃剂添加到软质聚氯乙烯(PVC)材料中。利用X射线衍射对PVC/有机改性载铜蒙脱土的结构进行表征。结果表明，PVC分子链插层进入有机改性载铜蒙脱土层间形成插层型结构，且蒙脱土的层间距达到3.69 nm。热重分析、极限氧指数、垂直燃烧和烟密度测试结果表明，有机改性载铜蒙脱土有效改善了PVC的热稳定性，大幅提高了其阻燃性能。载铜蒙脱土的用量仅为PVC用量的3 %时，垂直燃烧即可达到V0级。

| Abstract: | Cu-loaded montmorillonite was prepared via ion exchange and treated with hexadecyl trimethy ammonium bromide, which was introduced into PVC matrix forming a nanocomposite. X-ray diffraction showed that the obtained nanocomposite was an intercalation structure. Measurements of thermal gravimetric analysis, limited oxygen index, vertical burning test and smoke density test revealed that the intercalated montmorillonite enhanced the char-formation, thermal stability and flame retardant properties of PVC matrix. |
