以三聚硫氰酸(TCY)为交联剂对丙烯酸酯橡胶(ACM)进行交联制得ACM/聚四氟乙烯(PTFE)渗透汽化复合膜.用红外光谱(FT-IR)研究了交联反应机理,用扫描电镜(SEM)表征ACM/PTFE复合膜微观结构.考察了交联剂用量、交联温度、料液浓度和料液温度对复合膜渗透汽化法分离乙酸乙酯/水性能的影响.FT-IR表明,TCY的-HS基和ACM的-CH2Cl基之间发生了脱HCl反应.当m(TCY):m (ACM)为5:100,在150℃交联2h所制的复合膜在50℃时,对7％的乙酸乙酯/水溶液渗透通量为3631 g/(m2·h),分离因子为239.升高温度至70℃时,渗透通量可达7918g/(m2·h),分离因子降低到195.
