摘要：以桐油为原料合成了三官能度的缩水甘油酯,采用核磁共振和红外光谱确认了产物结构。将三缩水甘油酯与环氧树脂E51共混,并由潜伏性固化剂594固化,通过力学性能测试及热重分析对固化物的性能进行了研究。结果表明,固化物的断裂伸长率随桐油基三缩水甘油酯含量的增加逐渐增长,表明合成的环氧树脂具有良好的柔韧性,但与此同时,固化物的硬度、拉伸强度、玻璃化转变温度均呈下降趋势。固化物的初始分解温度可达400℃以上,具有优异的热稳定性。
The tri-functional glycidyl ester was synthesized from tung oil,and the product structure was confirmed by nuclear magnetic resonance and infrared spectroscopy. The triglycidyl ester was blended with epoxy resin E51 and cured by latent curing agent 594. The properties of the cured product were studied by mechanical property test and thermogravimetric analysis. The results showed that the elongation at break of the cured product was increased with the increasing of tung oil-based triglycidyl ester content,indicating that the synthesized epoxy resin had good flexibility. At the same time,the hardness,tensile strength and transformation temperature of the cured product showed a downward trend. The initial decomposition temperature of the cured material was up to 400 ℃ or more,with excellent thermal stability.
