《山东冶金》 2006 年第 6期金属表面防腐用含聚四氟乙烯复合涂膜的研制樊占国,李晶,杨中东,李凤华(东北大学材料与冶金学院,辽宁沈阳 110004 ) 摘要:聚苯硫醚( PPS )和聚酰亚胺( PI )具有高温熔流性以及与金属表面良好的粘接性, 将其与 PTFE 制成混合涂膜,即可以保持 PTFE 的耐腐蚀、耐高温和固体润滑的特点,又可与金属表面有良好的粘结强度。试制了 PTFE+PPS 、 PTFE+PPS 以及 PTFE+PPS+PI 三种复合涂料, 经比较得知, PTFE+PPS+PI 复合涂膜的性能最好, 其附着力为 1级, 柔韧性达到 1mm , 冲击强度大于 。还考察了涂膜的耐腐蚀性和抗热震性。关键词:金属防腐;复合涂料;聚四氟乙烯;涂膜工艺;涂膜性质中图分类号: ; 文献标识码:A 文章编号: 1004-4620 ( 2006 ) 06-0029-03 Preparation of posite Coatings on Metal Surface FAN Zhan-guo, LI Jing, YANG Zhong-dong, LI Feng-hua ( School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China ) Abstract : Polyphenylene sulfide ( PPS ) or /and polyimide ( PI) have high adhesive ability and fluidity on the metal surface, which may improve the properties of polytetrafluoroethylene ( PTFE ) coatings. The mixture coatings of PTFE 、 PPS 和 PI would possess the properties of corrosion resistance, high temperature resistance and solid lubrication of PTFE, and also have higher adhesive strength. In the paper the mixture coatings of PPS + PTFE, PI+ PTFE and PPS + PI+ PTFE were prepared. The adhesive force , ductility and impacting strength of the coatings on steel were measured, and the adhesive force is 1st grade , the ductility is 1mm and the impacting strength is over 500 . The physical properties of the coatings did not changed after 10 times recycling of heat-quenching, which sh
