摘要： 研究铝酸酯作为竹粉和聚己内酯的偶联剂对竹塑复合材料界面性能的影响。通过IR、X射线衍射(XRD)等现代分析手段揭示了偶联剂与竹粉的作用以及较佳的处理时间,并用转矩流变仪和示差扫描量热分析(DSC)考察偶联剂对竹粉和聚己内酯相容性的影响。结果表明,在一定的时间内,高速搅拌和偶联剂一起使竹纤维的有序结构遭到破坏,偶联剂的添加量为1.6%(相对竹粉用量)时,复合材料具有最好的加工性能。

关键词: 铝酸酯, 竹粉, 聚己内酯, 偶联剂

Abstract: The effect of aluminate coupling agent on interfacial properties between bamboo powder and polycaprolactone was studied in this paper. The interaction between coupling agent and bamboo powder and the best treatment time were determined by IR, XRD,etc.. The effect of coupling agent on compatability between bamboo powder and polycaprolactone was displayed by torque-rheometer and DSC. Results showed that both high-speed stirring and coupling agent destructed the ordered structure of bamboo fibre and the composite poccessed the best proccessing performance when the dosage of coupling agent was 1.6% of bamboo powder.

Key words: aluminate, bamboo powder, polycaprolactone, coupling agent
