摘要
采用具有优异拒水拒油表面性能的环保型“伞形”结构短氟碳链含氟聚合物与在极性基材上附着力强的环氧树脂共混,通过自分层技术,获得能一次涂装成型的梯度含氟涂层。采用接触角测试、X射线光电子能谱和能谱详细研究了自分层形成的梯度结构及分层机理;考察了溶剂选择、基材、树脂配比、分层时间和固化温度等因素对涂膜分层和涂膜性能的影响。研究表明,当静置分层时间为3h,固化温度为80℃,基材为极性基材(马口铁和玻璃板)时,该环保型自分层涂层既具有含氟聚合物的优良表面性能,又兼具环氧树脂的优异附着力。此方法为涂层材料既保持强附着力又实现表面优异的拒水拒油功能,提供了一条新的思路和途径。
Using an environmentally-friendly"umbrella"structure with excellent water and oil repellent surface properties,the short fluorocarbon chain fluoropolymer was blended with an epoxy resin with strong adhesion on polar substrate,it can be obtained once by self-stratification technology.The multi-coated and fluorine-containing coating was studied by contact angle test,XPS and SEM-EDS.The solvent selection,substrate,resin ratio and fraction were investigated.Studies show that when the standing stratification time is 3h,the curing temperature is 80℃,and the substrate is a polar substrate(tinplate and glass plate),the environmentally friendly self-layering coating has excellent surface properties of fluoropolymer.It also has excellent adhesion to epoxy resin.This method provides a new idea and way for coating materials to maintain strong adhesion and achieve excellent water and oil repellency.
