The cure properties of self-extinguishing epoxy resin systems with different charge transfer type latent catalysts were investigated, which are composed of YX4000H as a biphenyl epoxy resin, MEH-7800SS as a hardener, and charge transfer type latent catalysts. We designed and used five kinds of charge transfer type latent catalyst and compared to epoxy resin systems with Triphenylphosphine-Benzoquinone(TPP-BQ) as reference system. The cure kinetics of these systems were analyzed by differential scanning calorimetry with an isothermal approach, the kinetic parameters of all systems were reported in generalized kinetic equations with diffusion effects. These different cure conversion rates could be explained by the decrease of crystallinity of the biphenyl epoxy resin and the activation energy of these epoxy resin systems. The cure conversion rates of the epoxy resin systems with charge transfer type latent catalyst would be dependent on the activation energy of these systems. |
