摘要
以含无规两亲聚合物(ASRF)为稳定剂,甲基丙烯酸六氟丁酯(FA)、苯乙烯(St)等为单体制备出含氟丙烯酸酯共聚物无皂乳液表面施胶剂(FEE)。研究ASRF用量和热处理对FEE乳胶膜表面自由能的影响,以及ASRF用量、FEE与氧化淀粉复配比例对施胶效果的影响,并用SEM分析了施胶纤维形貌。结果表明:适当增加ASRF用量、提高处理温度,均有利于降低乳胶膜的表面自由能;当w(ASRF)用量为氟的5.0%、氧化淀粉含量不高于50%时,FEE及其复配施胶剂均具有良好的施胶效果;表面施胶后,纤维表面变得比较光滑,赋予纸纤维较低的表面自由能。
Fluorinated emulsifier-free emulsion surface sizing agent （FEE） was prepared by emulsifier-free polymerization of hexafluoro-butyl methacrylate （FA）, styrene （St） and so on in the presence of fuorinated random amphiphilic polymers （ASRF） copolymerized by FA, St and acrylatic acid. Effects of ASRF dosage and treatment temperature on the surface free energies of the films were investigated. Effects of ASRF dosage, composite ratio of FEE and oxidized starch on the application were also discussed. Additionally, fiber morphologies of the samples were characterized by SEM. qhe results showed that the appropriate increases of ASRF content and treatment temperature are good for the decreases of surface free energies of the films. When the ASRF dosage and oxidized starch dosage is 5% and less 50% respectively, the FEE and its combination with oxidized starch have good sizing performance. After the treatment by FEE, the fiber surface becomes smooth, which provides lower surface free energy of the fibers.
