使用3种不同结构的聚醚胺(Jeffamine D230,D400,T403)分别固化环氧有机硅杂化树脂制备出有机-无机杂化涂层,并与3-氨丙基三乙氧基硅烷(APTES)固化的杂化涂层在机械性能、附着力和防腐蚀性能上进行了比较。研究结果表明,与 APTES 相比,聚醚胺可以提高杂化涂层的耐冲击高度1倍以上；聚醚胺 D230和 T403没有降低杂化涂层的硬度,而D400降低了杂化涂层的硬度；聚醚胺可以明显提高杂化涂层的初始附着力,同时大幅改善了涂层在老化过程中的“湿附着力”。采用盐雾实验和交流阻抗测试研究了杂化涂层的耐腐蚀性能,结果表明聚醚胺固化剂明显改善了 APTES 固化杂化涂层的易开裂性,并提高了杂化涂层的耐腐蚀性能。

The organic-inorganic hybrid coatings based on epoxy polysiloxane resin were prepared by using three different polyetheramines (Jeffamine D230,D400,T403).The mechanical,adhesion and anti-corrosion proper-ties were compared with the hybrid coating cured by 3-aminopropyltriethoxysilane (APTES).Compared with the hybrid coatings cured by APTES,the impact resistance property,initial adhesion and “wet adhesion”of the hybrid coatings cured by polyetheramines were promoted,comparable hardness of the hybrid coatings cured by D230 and T403 were attained,while the hardness of hybrid coating cured by D400 was decreased.The corrosion resistance behavior of the hybrid coatings was thoroughly examined by electrochemical impedance spectroscopy (EIS)and salt spray tests.It was found that the cracking and corrosion resistance of the hybrid coatings cured by APTES were improved greatly by using polyetheramines hardeners.
