| Abstract: | Curing reaction of BPEA-2/epoxy resin was studied by DSC (differential scanning calorimetry) in this paper, in which BPEA-2 was a complex compound made from BF, and amine. The surface active energy of BPEA-2/CYD-128 was calculated out by Kissinger method and Arrhenius method. The curing reaction series and the constant of curing reactive rate for the system were obtained according to Crane theory, and the kinetic equation of the system was presented. As a result, the surface active energy of BPEA-2/CYD-128 latent curing system was 84. 11 kJ/mol, the reactive kinetic equation was -da/dt=k (1-a)~0. 96. |
