摘要: 在双螺杆挤出机上制备了聚丙烯/纳米黏土复合材料;考察了其结构对其抗熔垂性能的影响。X射线衍射分析结果表明,实验得到了插层结构聚丙烯/纳米黏土复合材料,不同的聚丙烯基体和相容剂用量影响材料的插层结构。抗熔垂性能研究发现,不同的插层结构,抗熔垂性能不同。其中,黏土片层插层结构的层间距与材料抗熔垂性能存在一定关联,插层结构中黏土片层层间距过大或过小都不利于抗熔垂性能的改善,层间距为2.90-3.00 nm的插层结构的聚丙烯/纳米黏土复合材料具有较好的抗熔垂性能。

Abstract: PP/nano-clay composites were prepared based on two different PP and various contents of compatibilizer PP-g-MAH on a twin-screw extruder.XRD curbes showed that the resultant composites exhibited intercalation structure,and PP matrixes and contents of the compatibilizer PP-g-MAH affected their intercalation structure.Sag resistance experiment indicated that the sag resistance of the composites changed with the intercalation structure.Neither large layer space nor small layer space of the clay is 2.90~3.00 nm,the sag resistance of the PP/nano-clay composite reached its highest value.

Key words: polypropylene, nano-clay, intercalation, sag resistance
