摘　　要：在双螺杆挤出机上制备了超高分子量聚乙烯/高密度聚乙烯复合材料,选择蒙脱土及粉煤灰玻璃微珠对超高分子量聚乙烯/高密度聚乙烯复合材料进行流动改性,采用XRD研究了蒙脱土在复合材料中的结构,研究了蒙脱土及粉煤灰玻璃微珠对复合材料流动性能的影响。研究结果表明:在低填充量下,蒙脱土及粉煤灰玻璃微珠可以提高超高分子量聚乙烯/高密度聚乙烯复合材料的流动性能。蒙脱土及粉煤灰玻璃微珠协同改性可以明显提高复合材料的流动性能。The composite of UHMWPE/HDPE was prepared by the twin-screw extruder. The structure of OMMT in composite was studied by XRD, the effects of MMT and micro-ball from fly ash on fluidity of UHMWPE/HDPE were investigated. The results showed that the melt fluidity of composite was improved remarkable when the content of MMT and micro-ball from fly ash was lower. The melt fluidity of UHMWPE/HDPE was improved more when the MMT and micro-ball from fly ash were both added.
