摘　　要：采用化学发泡法制备出高冲击强度聚苯乙烯(HIPS)微发泡材料及HIPS/纳米有机蒙脱土(nano-OMMT)复合微发泡材料。研究了发泡量对HIPS及其复合材料微发泡行为的影响。结果表明:随着发泡量的增加,发泡材料呈现欠发泡、均衡发泡、过发泡状态。发泡量取10%时,复合材料的发泡效果最好。nano-OMMT在发泡过程中起到成核剂的作用,促进泡孔成核,有效地改善了发泡质量。The HIPS micro-foam material and HIPS/nano-OMMT composite micro-foam materials were prepared by use of chemical foaming method.The effect of foam amount on the micro-foam behavior of HIPS and its composites was studied.The results show that： the foam material appears the less foaming state,balance foaming state and over foaming state with the increasing of foam amount;when the foam amount is 10%,the foaming effect of the composites is the best.During the foaming process,nano-OMMT plays a role of nucleating agent which can promote foam nucleation and effectively improve the foaming quality.
