摘要： 借助双转子连续混炼机，通过直接熔融插层法制备了聚乙烯/有机蒙脱土纳米复合材料，并用XRD测试了有机蒙脱土的层间距。分析了不同转子转速和喂料速率对聚乙烯有机蒙脱土复合材料层间距及其力学性能的影响。结果表明，选择适当的操作工艺以获得合适的剪切强度对于制备插层型聚乙烯有机蒙脱土纳米复合材料极为重要，当转子转速为400r/min，喂料速率为1.35kg/h时，制得的聚乙烯/有机蒙脱土复合材料层间距最大，插层效果最佳，有机蒙脱土的增强与增韧效果最好。

Abstract: Polye.thylene/organic-montmorillonite nano-composites were prepared using two-rotor continuous mixer via directly melting intercalation. the interlayer spacing was investigated by X-ray diffracLion (XRD).the effects of rotor speeds and feed rates on the interlayer spacing and the properties of nano-composites were investigated. It showed a proper shearing strength was important for preparing intercalated nano-composites. the maximum interlayer spacing could be achieved when the rotor speed was 400 r/min and the feed rate was 1 .35 kg/h，and the best tensile and impact strength of composites were obtained.

Key words: two-rotor continuous mixer, polyethylene, organic-montmorillonite, nano-composite
