RESIN COMPOSITON FOR HIGHLY THERMAL CONDUCTIVE INSULATING MATERAIL AND INSULATING FIME

摘要

PURPOSE: A resin composition is provided to offer an insulating material capable of realizing an excellent thermal conductivity without a degradation o inner voltage intensity. CONSTITUTION: A resin composition for insulating material comprises: a thermal conductive ceramic compound comprising alumina (Al2O3); graphene oxide; and a thermosetting resin. The graphene oxide is obtained from graphite oxide having more than 8.700 of d-spacing. The thermosetting resin comprises more than one kind selected among epoxy resin, polyimide resin, phenoxy resin, and acrylic resin. The insulating film comprises: a thermosetting resin hardened on the film; graphene oxide and thermal conductive ceramic compound dispersed in the thermosetting resin.
