| 摘 要： | 对蒙脱土进行有机插层改性制得有机蒙脱土(OMMT),用硅烷接枝木粉制备了有机蒙脱土/木粉/聚氯乙烯(OMMT/WF/PVC)纳米复合材料。加入的接枝木粉与OMMT分散在界面上起增强作用,有助于提高复合材料性能。用质量分数1.5%的偶联剂处理木粉,添加质量分数1.5%的OMMT时,复合材料的弯曲性能和抗蠕变性最好。用KWW模型和广义Voigt模型分析了蠕变曲线。

| Abstract: | Montmorillonite was modified as OMMT.Wood flour(WF) was grafted with silanet.From them,OMMT/WF/PVC nanocomposites were prepared.The modifications favored their interfacial adhesion of composites to boost the mechanical properties.1.5% silane grafting and addition of 1.5% OMMT improve best the flexural strength and creep resistance.KWW model and Voigt model were well used to analyze the effects of wood flour,silane and OMMT on creep of composites during loading and unloading. |

| Keywords: | montmorillonite PVC wood-plastics composites flexural properties creep resistance |
