摘　　要：使用原纤化的莱赛尔纤维与聚丙烯腈(PAN)纤维共混,添加黏结剂聚乙烯醇(PVA)、助滤剂SiO_(2),通过湿法成形的方法制备了PAN过滤纸板;通过细纤维交织与黏结剂协同作用增强PAN过滤纸板;对比分析了不同原纤化程度下过滤纸板的抗张指数、孔隙率、孔径及水通量。结果表明,当磨浆40 000转时,过滤纸板的综合性能较好,此时过滤纸板的抗张指数为5.97 N·m/g,孔隙率为88%,水通量为599 L·m^(2)/min,为水过滤用PAN过滤纸板的制备提供了参考。A polyacrylonitrile(PAN)filter paperboard was prepared by blending regenerated Lyocell fibers with PAN fibers,adding the binder polyvinyl alcohol(PVA),and filtering aid SiO_(2),with wet-forming method.The PAN filtration paperboard was enhanced through the synergistic effect of fine fiber interweaving and the binder.The tensile index,porosity,pore size,and water flux of the fil-ter paperboard at different levels of fiber regeneration were compared and analyzed.The results showed that when the pulp grinding for 40000,the filter paperboard exhibited optimal overall performance.At this point,the tensile index was the highest at 5.97 N·m/g,with porosity of 88%and water flux of 599 L·m^(2)/min.The reference was provided for the development of PAN filter paperboard for wa-ter filtration.
