摘要

研究了5种不同类型单宁对改善水性环氧树脂(EP)防蚀性能的影响。结果表明:引入低浓度单宁(<1.0%,wt,质量分数,下同),有助于提高环氧树脂涂膜的机械性能。由于缩合类单宁“聚集”效应更强,更容易在环氧树脂表面形成“漏点”,导致涂膜防蚀性能变差。五倍子单宁的引入对环氧树脂防蚀性能改善最佳,且当浓度为0.5%时,涂膜的耐中性盐雾时间可达528h,耐水时间超过180d。

Abstract

The effects of 5 different tannins on the corrosion resistance of waterborne epoxy resin (EP) were studied.The results showed that the introduction of low concentration tannin (<1.0wt%) was helpful to improve the mechanical properties of EP coatings.Because condensation tannins had stronger “aggregation” effect,they were more likely to form “leakage points” on the EP surface,resulting in poor corrosion resistance of the coating film.The introduction of gallnut tannin improved the corrosion resistance of EP the best,and when the concentration was 0.5wt%,the neutral salt spray resistance time of the coating was up to 528h,and the water resistance time was more than 180d.
