摘要： 阐述了超临界CO2发泡制备聚氯乙烯（PVC）微孔塑料不同工艺过程及其关键影响因素。介绍了CO2在PVC中的溶解扩散行为及CO2对PVC的增塑作用；分别论述了应用间歇升温发泡法、间歇降压发泡法和连续挤出发泡法制备PVC微孔材料的情况，分析了不同发泡工艺过程的优缺点，并总结了各发泡工艺过程中影响因素和PVC配方组成对发泡样品泡孔形貌和力学性能的影响；最后展望了超临界CO2发泡制备PVC微孔材料的工业化应用前景。

Abstract: This paper overviewed the foaming technology for preparation of microcellular polyvinyl chloride (PVC) using supercritical carbon dioxide (CO2) as physical blowing agent and introduced the dissolution and diffusion behaviors of CO2 in PVC and the effect of high CO2 plasticization on PVC. The different PVC foaming processes including batch step temperature rising foaming process, batch rapid depressurization foaming process and continuous extrusion foaming process were discussed, and both advantages and disadvantages of each process are analyzed. The effects of foaming condition and PVC formula composition on the cell morphology and mechanical properties of the foamed samples were also analyzed in detail. The industrial applications of microcellular PVC foamed with supercritical CO2 were prospected.
