摘　　要：利用磺化反应及热压处理,化学改性聚乙烯(PE)无纺布的亲水性和离子交换能力,讨论了时间、温度、热压压力等不同反应条件对材料力学性能的影响,使用显微镜(SEM)对磺化前后PE无纺布的外表状态进行观察,磺化后无纺布表面磺化效果有效提高.实验结果表明,PE无纺布的亲水性和离子交换水平在反应温度为85℃,热压压力为8 MPa,反应时间为2 h的磺化反应条件下,不仅PE无纺布的亲水性和离子交换能力得到了显著的改善,而且拉伸性能和耐腐蚀性能得到了较好保留.he hydrophilic property and ion-exchange capacity of PE non-woven fabric was improved by sulfonating and hot-pressing technique.The effect of time,temperature and the hot pressure on the property of hydrophilic and ion-exchange capacity of PE non-woven fabric were illustrated in detail.The microstructure of PE non-woven fabric was investigated with SEM,The effect of sulphurating PE non-woven fabric is excellently improved.The result shows that not only the hydrophilic property and ion-exchange capacity of PE non-woven fabric is excellently improved but also the original stretch intensity and corrosion resistance of PE non-woven fabric is well retained when the sulphuration temperature is 85℃,time is 2 h and hot-pressed pressure is 8 MPa.
