摘要
全氟聚醚具有极佳的化学惰性,不燃,可与塑料、弹性体、金属相容,只溶于全氟有机溶剂等良好的综合性能,是苛刻环境下极为可靠的润滑剂,广泛应用于电子、化工、核工业、航空航天等领域。其合成方法主要有全氟环氧化物的阴离子聚合法和全氟烯烃直接光氧化法2种。介绍了阴离子聚合法工艺流程、聚合机理及特征、影响聚合的因素等。
PFEP is chemical inert, non-flammable and compatible with all metals, elastomers and plastics. It also stands up to harsh solvents. It is applied widely in electronics, chemical engineering, nuclear industry, aircraft and so on. Synthesis methods of PFPE are mainly anion polymerization of perfluoro-epoxide and photo-initiated oxidation of perfluoro-olefine. This article is mainly about preparation methods, craft, principle and characteristics, influence factor, etc.
