PURPOSE: Provided is an epoxy resin composition for molding, which dose not pollute environment when disused and incinerated and is excellent in hardness, endothermic capacity, heat loss rate, insulation breakdown voltage, and fire retardancy. CONSTITUTION: The epoxy resin composition comprises 20-25wt% of an epoxy resin, 4-10wt% of a low viscosity epoxy resin as a reactive diluent, 0.1-0.5wt% of an additive comprising an epoxy vinyl resin as a coupling agent and a silicon resin as a foaming agent, 40-50wt% of aluminum hydroxide and/or calcium carbonate as a filler, and 14.5-35.9wt% of a fire retardant component comprising a mixture of melamine polyphosphate and ammonium polyphosphate, melamine polyphosphate, and barium nitrate. |
