综述了近年来国内外聚氯乙烯(PVC)/木粉(WF)复合材料的研究进展,对新型的行星辊轮双螺杆挤出机、带有干燥器的锥形双螺杆挤出机以及能直接将木粉输送到挤出机中的“WoodTruderTM”挤出系统等新型设备和工艺进行了介绍,对PVC/WF复合材料中使用的润滑剂、冲击改性剂、增塑剂、相容剂等助剂的研究进展进行了总结,并对PVC/WF复合材料的微发泡工艺和环保性能进行了介绍和评述,在此基础上对PVC/WF复合材料的发展趋势进行了展望。
In this paper, the research progress of polyvinyl chloride (PVC) / wood flour (WF) composites at home and abroad in recent years is reviewed. The effects of the new planetary twin screw extruder, conical twin screw extruder with dryer, New equipment and processes such as the “WoodTruder ™” extrusion system that delivers wood flour directly to the extruder are described. Lubricants, impact modifiers, plasticizers, and additives used in PVC / WF composites The progress of the research on PVC / WF composites was summarized. The micro foaming technology and environmental performance of PVC / WF composites were introduced and reviewed. The development trend of PVC / WF composites was also prospected.
