2. Description of the Related Art Conventionally, epoxy resins have excellent electrical properties,
Due to its excellent mechanical properties and crack resistance, and excellent adhesion to various materials, it is widely used for electrical insulation, especially for casting, especially for insulation protection and high voltage characteristics (arc resistance, tracking resistance). For the purpose of improving crack resistance and the like, for example, a flame-retardant epoxy resin composition containing a large amount of a filler and a flame retardant in an acid anhydride-curable epoxy resin is used. In general, a halogen-based flame retardant, a phosphorus-based flame retardant, an inorganic filler and the like are added to the flame-retardant epoxy resin composition to impart flame retardancy. However,
When these materials burn, harmful gases such as carbon monoxide, hydrogen cyanide, sulfur dioxide, and hydrogen halide are generated.Especially when halogen-based flame retardants are used, harmful substances such as halogenated benzodioxins and dibenzofurans are generated. Generation is worried. As a flame-retardant epoxy resin composition containing no halogen-based flame retardant, a phosphorus-based flame retardant has been conventionally used, but this composition has a problem that it is inferior in moisture resistance and heat resistance. In addition, when an inorganic flame retardant is used, sufficient flame retardancy cannot be obtained, and there is a problem that impregnation between the windings of the high-voltage transformer is reduced when the amount is increased.
