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 AbstractThe 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.
