| 摘 要： | 将木纤维先用一定质量分数的氢氧化钠(NaOH)溶液浸泡,再用硅烷偶联剂进行表面处理的两步改性方法,与只用硅烷偶联剂对木纤维进行表面改性相比,聚氯乙烯(PVC)/木纤维复合材料的界面黏合性提高,复合材料的力学性能如拉伸强度、冲击强度、断裂伸长率等有明显提高,改性效果显著

| Abstract: | Compared with only using silane coupling agent to deal with wood-fiber, the two-step modifying method of immersing wood-fiber into NaOH, then using silane coupling agent to deal with wood-fiber has following advantages: the interphase bonding of PVC/wood-fiber composite is increased, the mechanical properties of the PVC/wood-fiber composite such as the tensile strength, impact strength, and break elongation ratio are improved obviously. |
