The development of waterborne coating is essentially important for environmental protection, and cross-linking agent is of great significance for ensuring corrosion resistance of the coating. In this work, tetrabutyl titanate was modified by ethylene glycol and tris(2-hydroxyethyl) amine and used for the solidification of waterborne acrylic-epoxy resin. Fourier-transform infrared spectroscopy (FTIR) analysis revealed that the agent reacted with OH groups first to cross-link the resin preliminarily, and then, when the amount of agent was further increased, the amino groups opened epoxide rings resulting in a secondary cross-link. Field emission scanning electron microscope (FESEM) observation and electrochemical impedance spectroscopy (EIS) test found that, when the cross-linking agent was used at 6%, the coating remains intact and kept an impedance of as high as 108Ωcm2 even after being immersed in NaCl solution for 30 days. Copper-accelerated acetic acid-salt spray (CASS) test confirmed that the coating containing 6% cross-linking agent provided the best protection for the carbon steel substrate.

改性钛酸四丁酯交联水性环氧树脂涂料的耐腐蚀性能

水性涂​​料的发展对环境保护具有重要意义，而交联剂对于保证涂料的耐腐蚀性能具有重要意义。在这项工作中，钛酸四丁酯用乙二醇和三（2-羟乙基）胺改性，用于水性丙烯酸环氧树脂的固化。傅里叶变换红外光谱 (FTIR) 分析表明，该试剂首先与 OH 基团反应使树脂发生初步交联，然后，当试剂量进一步增加时，氨基打开环氧化物环，产生二次交联。关联。场发射扫描电子显微镜（FESEM）观察和电化学阻抗谱（EIS）测试发现，当交联剂用量为6%时，即使在 NaCl 溶液中浸泡 30 天，涂层仍保持完整并保持高达 108Ωcm2 的阻抗。铜加速醋酸盐雾（CASS）试验证实，含6%交联剂的涂层为碳钢基材提供了最好的保护。
