POTENT CURING AGENT OF EPOXY RESIN EMITTING HEAT AND ULTRA VIOLET RAY, AND EPOXY RESIN COMPOSITION AND EPOXY CURED MATERIAL CONTAINING THE SAME

摘要

PURPOSE: A potent curing agent of epoxy resin emitting heat and ultra violet ray, and epoxy resin composition and epoxy cured material containing the same are provided to give a good mechanical property, especially in case of epoxy resin composition of aliphatic epoxy(CAE) and/or bifunctional bisphenol-A type epoxy(DGEBA). CONSTITUTION: A curing agent is characterized in that the reaction thereof is performed only in which specific external energy such as heat or light is revealed thereon, except for the mixing state of the curing agents. N-benzylpyrazinium(BPH) containing hexafluoroantimonate(SbF6-) as the potent curing agent is synthesized by the use of benzylbromide and pyrazine as starting materials. An epoxy resin composition is characterized to be the mixture of CAE type epoxy resin, DGEBA type epoxy resin, or the mixture of the CAE resin and DGEBA resin in molar ratios between 60: 40 and 20: 80.
