摘　　要：[目的]提出一种操作简单、防腐效率高、耐摩擦性能强的金属表面防腐涂层的制备方法。[方法]以环氧树脂、氨乙基氨丙基三甲氧基硅烷、微米级纤维素颗粒、纳米级二氧化硅颗粒、正硅酸四乙酯、丙烯酸六氟丁酯等原料制备了一种封闭剂,采用空气喷涂法在铜基体上得到封闭涂层。[结果]丙烯酸六氟丁酯单体和修饰剂三氟丙醇的引入使涂层拥有较低表面能的同时又具有优异的粘附性。涂有封闭剂的铜片经历6000 h的盐雾试验后质量仅减少了7.4%左右,在王水中被完全腐蚀掉的时间比空白铜片延后了至少350 min。[结论]该封闭涂层具有优异的耐腐蚀和耐摩擦性能。[Introduction]A method for simple preparation of a highly anticorrosive coating with strong friction resistance on metals was proposed.[Method]A sealing agent was prepared with epoxy resin,aminoethylaminopropyltrimethoxysilane,micron cellulose particles,silica nanoparticles,tetraethyl orthosilicate,and hexafluorobutyl acrylate,and then coated on copper by air spraying.[Result]The introduction of hexafluorobutyl acrylate monomers and trifluoropropanol as modifier resulted in a coating with low surface energy and good adhesion.Copper sheets coated with the sealing agent lost only about 7.4% of their mass after 6000 hours of salt spray test,and the time to complete corrosion in aqua regia for them was delayed by at least 350 minutes as compared to the uncoated ones.[Conclusion]The seal coating exhibits excellent resistance to corrosion and friction.
