| 摘 要： | 以液体四氢甲基苯酐为固化剂,选用了多种胺类促进剂(包括脂肪类乙醇胺、脂环胺、脂肪胺、季胺盐、脲类)对双酚A缩水甘油醚类环氧树脂固化体系进行研究.从固化促进剂的相容性、凝胶时间、玻璃化转化温度、可使用时间等方面确定最佳配方.研究表明,脂环胺(N,N-二甲环己胺)、脂肪胺[三(二甲胺基丙基)胺]、季胺盐(2,2-二甲基丙酸季胺盐)可以促进双酚A缩水甘油醚类环氧树脂/液体四氢甲基苯酐固化体系的固化,并能使该体系的固化温度从160℃降低到100～120℃,力学性能达到玻璃钢缠绕和灌封浇注料的要求.

| Abstract: | Adopting liquid methyltetrahydro phthalic anhydride as curing agent,multiplicate amine catalyst(including aliphatic ethanol amine,cycloaliphatic amine,aliphatic amine,quaternary ammonium salt,urea)were used to study diglycidyl ether bisphnol-A epoxy resin system.The best formula was confirmed from the aspects of amine catalyst compatibility,gel time,Tg,pot life etc.The results showed that cycloaliphatic amine(N,N-dimethylcyclohexylamine),aliphatic amine(N′-dimethylpropane-1,3-diamine),quaternary ammonium salt(2,2-dimethyl-Propanoic acid ammonium salt)could accelerate the curing system by decreasing the curing temperature from 160℃ to 100-120℃ and satisfied the mechanical properties request of FRP wind and casting /encapsulation. |
