全氟聚醚表面活性剂的开发及在氟橡胶生产中的应用研究

Study on the Development of Perfluoropolyether Surfactant and Its Application in Fluororubber Polymerization

为解决全氟辛酸禁用的问题,开发出了一种新型全氟聚醚表面活性剂(FEC),并对该表面活性剂在氟橡胶聚合中的应用效果进行了研究。结果表明:用该全氟聚醚表面活性剂生产的氟橡胶乳液稳定、性能优越,可取代全氟辛酸在氟橡胶生产中的应用。

In order to solve the problem of prohibition of perfluorooctanoic acid, a new type of perfluoropolyether surfactant (FEC) has been developed, the application effect of FEC as emulsifier on the polymerization of fluororubber was studied. The results show the fluororubber produced by FEC latex is stable and superior in performance. Perfluorooctanoic acid can be replaced by FEC in the production of fluororubber.
