将甲基丙烯酸十二氟庚酯、丙烯酸丁酯、丙烯酸羟丙酯和甲基丙烯酸二甲氨乙酯进行乳液聚合,制得了一种稳定的阳离子氟代聚丙烯酸酯乳液。用红外光谱、核磁共振氢谱对共聚物结构进行表征,并用透射电镜对乳液的胶粒形态及粒径进行观察。单独使用质量分数为5.0%的该聚合物乳液进行表面施胶,结果表明:施胶量为1.2g·m-2,纸张的表面强度提高50.4%,抗张强度提高20.8%,耐折度提高28.6%,耐破指数提高15.1%。
Dodecafluoroheptyl methacrylate, butyl acrylate, hydroxypropyl acrylate and dimethylaminoethyl methacrylate were emulsion polymerized to prepare a stable cationic fluoro polyacrylate emulsion. The copolymer structure was characterized by IR and 1HNMR. The morphology and particle size of latex particles were observed by transmission electron microscopy. The surface sizing of the polymer emulsion with the mass fraction of 5.0% alone showed that the sizing amount was 1.2g · m-2, the surface strength of the paper increased by 50.4%, the tensile strength increased by 20.8% and the folding endurance increased 28.6%, bursting index increased 15.1%.
