摘要：利用非溶剂致相转化法(NIPS)制备了PVC-P(VC-VAC)-MBS平板和中空纤维超滤膜,讨论了氯乙烯-醋酸乙烯共聚物[P(VC-VAC)]的含量对膜机械性能、亲水性、纯水通量及截留率等性能的影响。同时,通过添加抗冲击改性剂甲基丙烯酸甲酯-丁二烯-苯乙烯共聚物(MBS),考察了MBS对PVC平板超滤膜机械性能的影响.实验结果表明,当铸膜液中P(VCVAC)的质量分数为4%时,亲水性最好,纯水通量可由42.5L/(m^(2)·h)增大到155L/(m^(2)·h);同时,膜的机械性能明显增强,P(VC-VAC)和MBS树脂可以有效地改善PVC超滤膜的亲水性和机械性能,是优良的PVC膜共混改性材料.
In this paper,PVC-P(VC-VAC)-MBS flat and hollow fiber ultrafiltration(UF)membranes were prepared by non-solvent induced phase separation(NIPS).With the changes of vinyl chloride-vinyl acetate copolymer[P(VC-VAC)]content,the mechanical and hydrophilic properties,water flux and rejection rate were investigated.Then,methyl methacrylate-butadiene-styrene copolymer(MBS)were added in the dope solution,their impacts on the mechanical properties of PVC flat membrane were examined.The experimental results show that the best performance can be get when the P(VC-VAC)content is 4%.The pure water flux was increased from 42.5L/(m^(2)·h)to 155L/(m^(2)·h).At the same time,the mechanical properties of the membranes were significantly enhanced.P(VC-VAC)and MBS are excellent modified material.They could significantly improve the hydrophilic and mechanical properties of the PVC membrane.
