采用有机单体甲基丙烯酸甲酯(MMA)本体聚合制得MMA预聚液,与氧化铝粉体混合后制得陶瓷膜。并对MMA预聚液、陶瓷膜进行了表征。研究结果表明:在温度为90℃,引发剂过氧化二苯甲酰(BPO)用量为0.1%(wt,质量分数),聚合时间11.5min条件下,制得的MMA预聚液黏度适宜,与50%(固相体积分数)氧化铝粉体混合后制得的陶瓷膜表面光滑,结构完整,对分散大红染料的截留率可达98%以上。
MMA prepolymer prepared by bulk polymerization mixed with the alumina powder to prepare the ceramic membrane.MMA prepolymer and ceramic membrane were characterized.The results showed:temperature 90℃,the initiator dosage of BPO 0.1wt%,the prepolymerization time 11.5min were the best condition for obtaining MMA prepolymer with proper viscosity.The asymmetric ceramic membrane with smooth surface and complete structure was prepared by MMA prepolymer 50% mixing with alumina powder,and the retention rate of disperse red dye was more than 98%.
