含氟丙烯酸酯乳液的合成及其应用

以苯乙烯、丙烯酸-2-乙基己酯和甲基丙烯酸十二氟庚酯为反应单体，在阴／非离子复合乳化剂条件下，采用乳液聚合方法制备含氟丙烯酸酯乳液．通过优化工艺条件，得到了性能较好的含氟拒水整理剂．对其进行红外光谱分析，结果表明加入的单体已成功引入到共聚物链段中．用合成的含氟聚丙烯酸酯乳液对纯棉织物进行织物的拒水整理，得到该整理剂的最佳应用工艺为：整理剂用量50g／L，轧余卒80％，100℃预烘3min，170℃焙烘180s．

Synthesis and application of fluorinated polyacrylate emulsion

Under the existing of anionic/nonionic complex emulsifier, the fluoroacrylate emulsion was prepared by emulsion polymerization with styrene, 2-ethylhexyl acrylate, dodecafluoroheptyl methacry late as monomers. The spectra of FT-IR confirmed that fluorined methacrylate units were incorporated into the copolymers. By optimizing the process conditions, a better performance fluorinated water repel- lent finishing agent has been got. By applying the fluoroaerylate emulsion on the water repellent of cot- ton fabrics, the best conditions are as follows, the dosage of the finishing agent is 50g/L,the pick-up is 80%, pre-drying at 100℃ for 3～Smin and curing at 170℃ for 180 seconds.
