| 摘 要： | 通过 DSC法研究了 LEPB、双酚 A型环氧树脂 E-51和 TDE-85型环氧树脂与四种芳基碘钅翁盐的热固化行为及反应活化能。结果发现 ,双酚 A型环氧树脂固化反应的活化能较高 ,而 TDE-85的放热较集中。同时发现与酸酐固化剂相对照 ,本文中使用的 LEPB—固化剂体系的活化能 (78.66～ 1 0 2 .5k J· mol-1)普遍高于LEPB酸酐体系的活化能 (69.0 4～ 75.1 0 k J·mol-1)。

| Abstract: | The curing behavior and reaction activation energies of LEPB andepoxy resin with diphenyl propane type E-51 and TDE-85 with four different oxomiumiodids as curing agents have been studied by use of DSC method.The experimental results demonstrate that the activation energy of epoxy resin with diphenyl propane type are higher than those of TDE-85 and the free heat of TDE-85 is more concentrated.It was found that the activation energies of LEPB curing agents system (78.66～102.5kJ.mol-1) are generally higher than those of LEPB-anhydrides system (69.04～75.10kJ.mol-1). |
