| 摘 要： | 采用一步模压法制备聚氯乙烯/木粉(PVC/WF)复合发泡材料,研究木粉(WF)的预处理、用量及粒径对PVC/WF复合发泡材料力学性能、尺寸稳定性、密度、吸水性及吸油性能的影响,并通过扫描电镜(SEM)对其泡孔结构进行分析.结果表明:WF经预处理,PVC/WF复合发泡材料拉伸强度有所增强,密度和吸水率略有减小,吸油性尤明显变化,耐热性稍有降低;随着WF粒径的增加,PVC/WF复合发泡材料的密度、吸水率、吸油率和线性收缩率均增大,拉伸强度从1.25MPa增大到1.78 MPa,断裂伸长率随之减小;随着WF含量增加,PVC/WF复合发泡材料密度和吸油率均明显增加,拉伸强度也随之增大,线性收缩率减小,吸水率先增大后减小,WF质量分数10%时吸水率最大.

| Abstract: | PVC/WF composite foaming material was prepared by one-step compression molding.Effects of the WF pretreatment,the content and particle size of WF on mechanical properties,dimensional stability,density,water absorption and oil absorption of PVC/WF composite foaming material were studied.The foam structures were analysed by SEM.The results show that the tensile strength of the PVC/WF composite foaming material is increased, but density,water absorption and oil absorption are decreased slightly,and heat resist... |
