| Abstract | 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％NaCI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． |
| Other Abstract | The protection performance of four polymer/Dacromet composite systems, namely three solventborne 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 % NaCI 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 properties of organic polymers and existence of the dispersed micro - organic 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 ot： the polymer. |
