A new epoxy resin based on dichlorosilane and 9,9-bis (4-hydroxyphenyl) fluorene was synthesized to produce a highly heat-resistant network. The chemical structure was characterized with FTIR spectroscopy and 1H-NMR. 4-4′-Diaminodiphenylsulfone (DDS) was used as the curing agent. The curing kinetics of different epoxy/DDS systems were investigated using non-isothermal differential scanning calorimetry (DSC). The results showed that the values of activation energy (E) were affected by the chemical structure of epoxy resin, and BPEBF exhibited lower curing reactivity towards DDS compared to E-51.

In this paper, 2-phenyl imidazole (2-PZ) microcapsule-type curing agent of epoxy resin were prepared through solvent volatilization with 2-PZ and polymethyl acrylic glycidyl ester (PGMA) as the raw materials. The micro-morphology, shape and structure of the microcapsules were studied by scanning electronic microscope (SEM) and fourier transform infrared spectrum (FT-IR). The curing kinetics of microcapsule curing agent/epoxy resin E-44 curing system were studied using TGA/DSC simultaneous thermal analyzer. Results showed that the preparation method is simple and effective and the prepared 2-PZ microcapsules have smooth surfaces and monodisperse size. And the curing kinetic study of epoxy resin system suggested epoxy resin curing temperature was rising with the increase of heating rate.
