摘要
采用动态差示扫描量热法(DSC)研究了炔丙基三嗪类新型多功能固化交联剂TPC与叠氮黏合剂GAP的固化反应动力学。根据所测量的不同升温速率的DSC曲线,采用Kissinger和Crane方程计算了GAP/TPC体系的动力学参数,建立了GAP/TPC体系的固化动力学方程。结果表明:TPC与GAP的固化反应为一级反应,反应级数n=0.935,表观活化能Ea=97.30 kJ/mol,表观频率因子A=2.38×1012min–1。
The curing reaction kinetics of the novel multi-functional cure-crosslinking agent propargyl triazine TPC with azide binder GAP was studied by dynamic differential scanning calorimetry（DSC）.According to the measured DSC curves at different heating rates,the kinetic parameters of the GAP/TPC system were calculated by using the Kissinger equation and the Crane equation,and the curing kinetic equations of GAP/TPC system were established.The results show that the curing reaction of TPC with GAP is first order reaction,the reaction order n = 0.935,the apparent activation energy Ea= 97.30 kJ/mol,the apparent frequency factor A = 2.38×1012min–1.
