氟代聚丙烯酸酯无皂乳液整理剂的防水防油性能研究

Study on the Water and Oil Repellency of the Fluorinated Polyacrylate Soap-free Emulsion Textile Finishing Agent

摘要:

本文采用无皂乳液聚合法，以全氟烷基酯（FEA）为功能单体，制备了一种氟代聚丙烯酸酯无皂乳液整理剂，并对其乳液颗粒粒径大小及分布和高分子溶液表面活性进行了研究。通过对棉织物进行防水防油整理应用实验，详细考察了该织物整理剂的使用质量百分数和烘焙温度对防水防油性能的影响，并测试了其他应用性能。结果表明，通过该防水防油剂处理的织物有优异的防水防油性能，处理后的织物表面动态防水性可达90分，防油性可达5级，对水的接触角可达142.5°，对石蜡油的接触角可达126?，并且有良好的耐水洗性和常规应用性能。

Abstract:

A kind of fluorinated polyacrylate soap-free emulsion textile finishing agent was prepared using perfluoroalkyl acrylate (FEA) as functional monomer by soap-free emulsion copolymerization, and the size and distribution of emulsion particle and the surface activity of polymer solution were studied. With water and oil repellency textile finishing application experiment, the effects of the textile finishing agent dosage and the baked temperature were discussed in detail, and other performances were tested. The result showed that, the textile finished by the said water and oil repellency textile finishing agent had excellent water and oil repellency properity, its dynamic waterproofing score was 90 point and the oil-proofing grade could reach above level 5, the water contact angle is up to 142.5° and oil contact angle is up to 126° through finishing treatment, and it had good washing durability and general performance.
