摘要：采用FT-IR光谱研究了氢化萜烯马来酸酐(HTMA)与双酚A型环氧树脂的固化反应过程,并分析了固化度、凝胶时间及其主要影响因素。实验结果表明:HTMA与环氧树脂的固化反应过程与促进剂作用下的酸酐固化环氧树脂的交联反应机理一致;固化度随温度升高、时间延长而提高,而凝胶时间随温度升高、促进剂用量的增加明显缩短。HTMA与双酚A型环氧树脂在110℃、8h以上可完全固化。空间位阻效应及电子效应的协同作用使HTMA与环氧树脂的固化反应速度降低,固化过程中放热量小,放热平缓。
The curing reaction of hydrogenated terpinene maleic anhydride （HTMA）with bisphenol A epoxy resin was investigated by FT-IR spectrum, and the curing degree, gelation time and its affecting factors were analyzed. The experiment results indicated that the cross-linking mechanism of hydrogenated terpinene maleic anhydride with bisphenol A epoxy resin was similar to anhydride curing with epoxy resin in the presence of accelerants. The curing degree was increasing as the curing temperature was arisen and the curing time was delayed, and the gelation time was shortened obviously as the curing temperature was arisen and the dosage of accelerants was increased. HTMA cured with bisphenol A epoxy resin completely at 110℃ in 8 h. HTMA cured with epoxy resin gently and slowly, owing to the synergistic effect of steric hindrance effect and stereo-electronic effect.
