摘要: 通过EIS研究了以碳钢为基体的醇酸、聚氨酯、苯丙乳液以及氟树脂4种有机聚合物/达克罗复合涂层体系在3.5%NaCl中的防护性能。结果表明，氟树脂/达克罗复合体系表现出最好的防护性能，水性的苯丙乳液体系次之，聚氨酯体系居中，醇酸体系最差。γ-氨基丙基三乙氧基硅烷（γ-APS）对达克罗涂层表面进行预处理可以较大程度地提高醇酸、聚氨酯复合体系的耐蚀性能，但降低了水性的苯丙乳液体系的防护性能，对氟树脂体系的影响不明显。

Abstract：The protection performance of four polymer/Dacromet composite systems, namely three solvent-borne polymers, polyurethane, alkyd primers and fluorinated polymer as well as a water-borne coating, styrene-acrylate latex, was studied with or without pretreatment by gamma-aminopropyltriethoxysilane (γ-APS) by electrochemical impedance spectra (EIS) in 3.5%NaCl solution. The results showed that the sequence of protective performance was: fluorinated polymer>styrene-acrylate latex>polyurethane>alkyd/Dacromet composite system due to the different hydrophobic Pretreaties of organic polymers and eistence of the dispersed microorganic particles in styrene-acrylate latex. Pretreatment with γ- APS on Dacromet illustrated a markedly enhanced anti-corrosion performance of the polyurethane and alkyd/Dacromet systems because of the presence of the silane film restrained the diffusion of corrosive particles. But it also suppressed the synergetic protective effect in styrene- acrylate latex system,which led to decrease anti- corrosion performance. Pretreatment presented no obvious influence on fluorinated polymer/ Dacromet system due to the good hydrophobic property of the polymer.

Key words： Dacromet composite coating EIS anti-corrosion performance γ-APS pretreatment
