摘　　要：利用环氧树脂与有机硅树脂的不相容性,制备出无溶剂可自分层固化环氧-有机硅涂层。通过对比不同环氧树脂及环氧固化剂分层效果,分析环氧树脂及环氧固化剂对无溶剂自分层涂料分层效果的影响;通过对无溶剂自分层涂料中组分/材料的表面张力、密度、相容性的研究,总结无溶剂自分层涂料的分层影响因素并探讨分层机理。A series of solvent - free self - stratification coatings containing two incompatible resins, epoxy and silicone, which spontaneously stratify after curing, have been prepared. The influence of different epoxy/curing agent on stratification results of solvent - free self - stratification coating was analyzed by assessing the stratification effectiveness of coatings. The influencing factors on coatings stratification and the stratification mechanism were also revealed by characterizing the surface tensions, specific gravity and compatibility of the coatings components and coating systems
