A corrosion-indicating material and methods of producing and using the corrosion-indicating material are provided. The corrosion-indicating material comprises a cured product of reacting a bisphenol A diglycidyl ether epoxy (DGEBA) resin with a curing agent, the curing agent comprising a 1,10-phenanthroline derivative having formula (I):
where: R1 and R2 are independently selected from —NH2; —NH(CH2)aNH2, where a is 1, 2, or 3; —OC(═O)(CH2)bNH2, where b is 1, 2, or 3; and —H; R3 and R4 are either: non-joined monovalent radicals each independently chosen from —H, —NH2, and (C1-C20)heterohydrocarbyls comprising at least one primary amine or at least one secondary amine; or joined as a single divalent radical, the single divalent radical being a (C1-C40)heterohydrocarbyl comprising at least one primary amine or at least one secondary amine; and at least one of R1, R2, R3, and R4 is not —H.
本文提供了一种腐蚀指示材料以及生产和使用该腐蚀指示材料的方法。腐蚀指示材料包括双酚 A 二缩水甘油醚环氧树脂(DGEBA)与固化剂反应的固化产物,固化剂包括具有式(I)的 1,10-菲罗啉衍生物:
其中R1和R2独立地选自-NH2;-NH(CH2)aNH2,其中a为1、2或3;-OC(═O)(CH2)bNH2,其中b为1、2或3;和-H; R3和R4或者是各自独立选自-H、-NH2 和包含至少一个伯胺或至少一个仲胺的 (C1-C20)heterohydrocarbyl 的非连接单价基;或连接为单个二价基,该单个二价基为包含至少一个伯胺或至少一个仲胺的 (C1-C40)heterohydrocarbyl ;且 R1、R2、R3 和 R4 中至少有一个不是-H。
