含氟烷基修饰的PU-PA防水防油剂应用性能

采用异佛尔酮二异氰酸酯、聚醚二醇、N 甲基二乙醇胺、全氟烷基乙基醇和丙烯酸羟乙酯等聚氨酯链段进行聚合反应，经水乳化分散后，再以全氟烷基酯等烯丙基单体进行自由基聚合反应，制备全氟烷基修饰聚氨酯 聚丙烯酸酯织物防水防油整理剂。探讨了该织物整理剂的用量和烘焙温度对织物防水防油性能的影响。结果表明，表面动态防水性可达100分，防油性可达5级，对水的接触角可达133°，对液体石蜡的接触角可达116.5°，且耐水洗性和服用性能较好。

Application performance of water- and oil- repellent of perfluoroalkyl modified PU-PA

Using isophorone diisocyanate, polytetrahydrofuran ether diol, N methyldiethanolamine, perfluorooctyl ethyl alcohol perfluoroalkylol and 2 hydroxyethyl acrylate as the segments,the water and oil repellent, perfluoroalkyl modified polyurethane polyacrylate, is synthesized via polymerization reaction, water emulsion dispersion, and radical polymerization with allyl monomers including perfluoroalkyl ester. The effect of dosage of the agent and curing temperature on the water and oil repellency results are discussed. The results show that the finished fabric features 100 point of dynamic waterproof, 5 Grade of oil repellency, 133°of contact angle to water, 116.5°of contact angle to oil, good washing durability and satisfied wear performance.
