【摘要】 以环氧树脂、聚醚胺固化剂和各种填料制备了无溶剂防腐涂料,用正交试验法研究了影响环氧无溶剂防腐涂料防腐性能的主要因素,结果表明环氧无溶剂防腐涂料具有优良的耐碱耐盐性能,影响涂料耐酸性的主要因素是固化剂含量。应用电化学阻抗谱EIS研究了涂层在酸性、碱性和盐介质中的腐蚀行为。EIS研究表明优化配比涂料在硫酸溶液中浸泡时阻抗值下降最快,其次是在氢氧化钠溶液中,在氯化钠溶液中浸泡时阻抗值下降最慢。更多还原

【Abstract】 Preparaed solventless anti-corrosive epoxy coatings by using bisphenol A epoxy resin,polyether amine curing agents and various fillers.Using orthogonal research the main factor impacting anti-corrosive performance of solventless anti-corrosive epoxy coatings and the results showed coatings has excellent anti-corrosive performance.Curing agents is the main factor of impacting coatings’ acid resistance.Researched the corrosion behavior in optimal ratio of coatings immersing in acidic,alkaline and salt medium during the corrosion process by Application electrochemical impedance spectroscopy.更多还原
