摘　　要：采用非等温DSC对胺丙基低聚倍半硅氧烷(NH2-POSS)/环氧树脂(E51)/4,4-二氨基二苯砜(DDS)体系的固化过程进行研究。利用外推法确定体系的固化工艺条件,通过Kissinger和Ozawa方程计算体系的活化能,研究了n级和自催化模型对体系的适用性。结果表明,NH2-POSS/E51/DDS体系的活化能为68.01kJ/mol,且自催化动力学模型适用于固化体系。the curing process of aminopropyl oligomeric silsesquioxane(nh2-poss)/epoxy resin(E51)/4,4-diaminodiphenylsulfone(DDS)system was studied by non isothermal DSC.The curing conditions of the system were determined by extrapolation,and the activation energy of the system was calculated by Kissinger and Ozawa equations.The applicability of N-level and autocatalytic model to the system was studied.The results show that the activation energy of nh2-poss/E51/DDS system is 68.01kJ/mol,and the autocatalytic kinetic model is suitable for curing system.
