Abstract:

A kind of thermally stable epoxy resin containing aromatic thiazole groups(TDABZ) was prepared. The structure of TDABZ was characterized by Fourier transform infrared spectra(FTIR), and the thermal degradation kinetics parameters were determined by thermogravimetric analysis-derivative thermogravimetry(TGA-DTG). The thermal stability of the cured resin was studied by thermogravimetric analysis(TGA) and dynamic thermomechanical analysis(DMTA). TDABZ was completely cured under controled condition by the reaction between epoxy group and the active nitrogen in DDS/2-ABZ. The activation energy value calculated by the Kissinger's and Ozawa's methods is 205.5 kJ/mol and 221.9 kJ/mol, respectively. The cured TDABZ exhibits excellent thermal stability with the glass transition temperature(Tg) of 242.3 ℃, the temperature of 5% mass loss(Td5) and the temperature at maximum mass loss rate(Tdmax) are 242.3 ℃ and 395.5 ℃, respectively, and the residue at 600 ℃ is up to 24.1%, which can improve the thermal stability of epoxy resin, and broaden its applications.
