摘　　要：为制备一种新型处理污水的过滤布,采用浸渍法将活性炭和分散剂1788型PVA以及表面活性剂十二烷基硫酸钠按比例混合并均匀涂覆在黏胶非织造布上从而制备了黏胶活性炭非织造过滤布(VC-ACF),并对此多层复合材料顶破性能,金属离子过滤以及染料过滤等性能进行研究。结果表明:随着1788型PVA以及十二烷基硫酸钠的增加,VC-ACF的透气性先增加后减小,在1788型PVA、十二硫酸烷基钠与活性炭质量比为1∶1∶3时透气性最佳;当载炭量为2.7 g/cm^2时,织物顶破性能最佳;当载炭量为1.8 g/cm^2时,织物过滤Cu^(2+)性能最佳,过滤染料亚甲基蓝性能最佳。In order to prepare a new type of filter cloth to treat sewage,the activated carbon,dispersant 1788 type PVA and the surfactant sodium dodecyl sulfate were mixed in proportion and uniformly coated on the viscose nonwoven with impregnation method to prepare viscose activated carbon non-woven(VC-ACF),and the properties of multi-layer composite materials such as bursting performance,metal ion filtration and dye filtration were studied.The results showed that the permeability of VC-ACF increased first and then decreased with the increase of 1788 PVA and sodium dodecyl sulfate.When the mass ratio of 1788 PVA,sodium dodecyl sulfate and activated carbon was 1∶1∶3,the air permeability was the best.When the carbon content was 2.7 g/cm^2,the fabric had the best bursting property.When the carbon content was 1.8 g/cm^2,the Cu^2+filtration property and methylene blue filtration property of the fabric was the best.
