摘要
以松香酸和马来酸酐为原料,通过D-A反应合成了高纯度的马来海松酸酐,用IR、NMR、元素分析等对其进行了结构表征。在此基础上,分别用马来海松酸酐和偏苯三酸酐对环氧树脂DER 662E进行固化,并用DMA、力学性能测试仪、TGA等对比研究了固化后环氧树脂的模量、玻璃化转变温度、拉伸强度等力学性能和耐热性能。探索了生物基马来海松酸酐作为环氧树脂固化剂替代石油基偏苯三酸酐的可能性。
Maleopimarate was synthesized from abietic acid and maleic anhydride by D-A reaction.Its characterization was performed by IR,NMR and element analysis.Epoxy DER 662E was cured with maleopimarate and trimellitic anhydride,respectively.The modulus,glass transition temperature and tensile strength as well as thermal stability of cured epoxy were evaluated by DMA,Instron Machine and TGA.The feasibility of bio-based maleopimarate as an alternative to petrochemical-based trimellitic anhydride for using as an epoxy curing agent was studied.
