摘要:
以球形铝粉为主要防腐颜料,制备了一种水性磷酸盐耐高温防腐涂料(牌号为ZK052),该涂料具有优异的防腐和耐高温盐雾性能。通过电化学测试、高温盐雾加速试验和腐蚀形貌表征,探究该涂料对碳钢基底的耐高温防腐机制,并对比研究该涂料与国外知名Sermetel W水基含铝耐高温防腐涂料的耐温性和耐蚀性。结果表明,ZK052涂层和Sermetel W涂层均对碳钢具有良好的耐高温防腐性能;ZK052涂层和Sermetel W涂层可同时抑制碳钢在质量分数为5%的NaCl溶液中的阳极氧化反应和阴极还原反应,将碳钢在5% NaCl溶液中的自腐蚀电流密度降低10倍。
Abstract:
A kind of waterborne phosphate high temperature resistant anticorrosive coating (grade ZK052) was prepared in this paper, and coated spherical aluminum powder was used as pigment. The ZK052 coating exhibited excellent anti-corrosion and high-temperature salt spray resistance. The electrochemical testing, high-temperature salt spray accelerating test and corrosion morphology characterization were used to explore the high temperature resistance and corrosion resistance mechanism of the coating on carbon steel substrate. The high temperature resistance and corrosion resistance of ZK052 and Sermetel W water-based coatings coated on Q235 carbon steel were compared. Results indicated that ZK052 coating and Sermetel W coating exhibited good high temperature resistance and corrosion resistance to Q235 carbon steel. Both ZK052 coating and Sermetel W coating could inhibit both anodic oxidation and cathodic reduction of carbon steel in 5wt% NaCl solution, and reduce the self-corrosion current density of carbon steel in 5wt% NaCl solution by 10 times.
