用示差扫描量热仪 ( DSC)对含联苯结构环氧树脂 ( TMBP) /4,4′-二氨基二苯砜 ( DDS)固化体系的固化反应过程进行了分析 ,并用 Kissinger和 Ozawa方法分别求得体系固化反应的表观活化能 ΔE为 69.7和74.2 k J/mol,根据 Crane理论计算得到该体系的固化反应级数 n=0 .89及在不同升温速率下的频率因子 A,确定了使用 DDS作为固化剂的固化反应条件
The curing reactions of TDC / 4,4’-diaminodiphenylsulfone (DDS) curing system were analyzed by differential scanning calorimetry (DSC) and analyzed by Kissinger and Ozawa methods The apparent activation energy ΔE of the curing reaction was 69.7 and 74.2 kJ / mol respectively. According to the Crane theory, the curing reaction order n = 0.89 and the frequency factor A at different heating rates were determined. Curing reaction conditions using DDS as a curing agent
