Abstract
A novel heat released microcapsule-type latent curing agent was successfully prepared by solvent evaporation technique with 2-phenylimidazole (2PZ) as core material and polyglycidy methacrylate (PGMA) as wall material. Systematic study of the effects of the kind of solvent and oil-water ratio, type and amount of surfactant, the core-shell feed ratio were carried out on the morphology of microcapsules, particle size and distribution, 2PZ content and yield, etc. When the solvent is methylene chloride, oil-water ratio is 4:5, surfactant is 0.4%(mass fraction) SDS and core-shell weight ratio is 1:1, the optimized preparation of the microcapsule curing agent is obtained.
