摘    要:采用热重法(TG-DTG)研究了2种含有柔性链和刚性结构单元的端胺基聚氨酯(ATPU-2和ATPU-1.5)对环氧树脂E-44固化物热稳定性特点和热分解动力学的影响。结果表明,固化剂ATPU-2与E-44固化物的热分解温度高于ATPU-1.5/E-44体系的固化物,ATPU-2/E-44固化物的分解残余量也高于ATPU-1.5/E-44体系。表明ATPU-2/E-44体系具有更好的热稳定性。固化反应动力学研究表明ATPU-2/E-44固化物的分解反应活化能高于ATPU-1.5/E-44体系。

关 键 词:端胺基聚氨酯(ATPU)  环氧树脂(E-44)  热稳定性  热分解动力学  活化能

Abstract:Thermogravimetry(TG-DTA) was used to study the heat resistance characteristics and curing heat decomposition kinetics of ATPU/Epoxy Resin System.Results showed that the decomposition temperature of the cured ATPU-2/E-44 was higher than that of ATPU-1.5/E-44.The calculation results of decomposition reaction showed that the cured system of ATPU-2/E-44 had better heat resistance,the reaction decomposition active energy of ATPU-2/E-44 system was higher than that of ATPU-1.5/E-44.
Keywords:amine-terminated polyurethane(ATPU)  epoxy resin  heat resistance  heat decomposition kinetics  active energy
