摘　　要：在明胶作用下,以苯乙烯、丙烯酸甲酯、丙烯酸丁酯、丙烯酸羟乙酯、甲基丙烯酸二甲氨基乙酯、全氟烷基乙基丙烯酸酯为原料,通过自由基共聚制备了阳离子氟碳乳液(CFE),通过粒径、AFM、FT-IR、热重、接触角测量仪等分别研究了CFE的乳胶膜表面形貌、结构特征、润湿性等;通过接触角法考察了CFE作为纸张表面施胶剂的应用效果。结果表明,在明胶添加量为1%时,CFE乳液稳定,乳液粒径120nm,水在纸张表面的接触角可达126°,涂膜具有良好的疏水性能。The cationic fluorocarbon emulsion （CFE） was prepared by the reaction of gelatin, styrene, methyl methacrylate, butyl acrylate）, hydroxyl ethyl methacrylate, methyl methacrylate dimethyl amino ethyl ester, whole fluoroalkyl acrylate ph, through the free radicals copolymerization. Through the DLS, AFM, FT-IR, TGA and contact angle, the CFE emulsion membrane surface morphology, structure characteristics, thermal stability and wettability were studied; the application effect of CFE used as paper surface sizing agent was investigated by contact angle analysis. The results showed that the content of gelatin is 1%, CFE emulsion is stable, latex particle size 120 nm and contact angle is up to 126°. The film has good hydrophobic property.
