摘　　要：以甲基丙烯酸甲酯(MMA)、全氟烷基乙基丙烯酸酯(FM)、丙烯酸十八酯(ODA)、丙烯酸丁酯(BA)、甲基丙烯酸二甲氨基乙酯(DM)为主要原料,以丙烯酸羟乙酯(HEA)为交联剂,以偶氮二异丁腈(AIBN)为引发剂,制备了水性阳离子全氟丙烯酸酯防水防油整理剂;讨论了含氟单体用量、软硬单体的质量比、整理剂用量、烘焙温度和烘焙时间对棉织物整理效果的影响,并通过红外光谱(IR)对产品结构进行表征。结果表明,在含氟单体用量为50%,硬软单体质量比为2.79,整理剂用量为2 g/L,烘焙温度160℃,烘焙时间90 s的条件下整理棉织物,织物表面对水的接触角可达136°,对液体石蜡的接触角可达125°,具有优异的防水防油性能。Water-based cationic perfluorinated polyacrylate water- and oil-repellent finish was prepared with methyl methacrylate （MMA）, perfluorinated alkylethylacrylate （FM）, octadecyl acrylate （ODA）, butyl acrylate （BA） and dimethylaminoethyl methacrylate （DM） as main materials, hydroxyl ethyl acrylate （HEA） as a crosslinker and azobisisobutyronitrile （AIBN） as an initiator. Influences of dosage of perfluorinated monomer, ratio of hard monomers to soft monomers, dosage of the finishing agent, curing temperature and time on finishing results of cotton fabric were discussed. Structure of the product was characterized by infrared spectroscopy （IR）. Results showed that under conditions of perfluorinated monomer 50%, ratio of hard monomers to soft monomers 2.79, finishing agent 2 g/L, and curing at 160 ℃ for 90 seconds, the finished cotton fabric had excellent water-and oil-repellency with water contact angle up to 136° and oil contact angle up to 125°.
