The filler-free halogen-free flame-retardant epoxy resin composition comprises a component A and a component B. The component A comprises the following components in percentage by weight: 55-75% of low-halogen bisphenol A epoxy resin 128, 5-15% of bisphenol F epoxy resin 170, 10-30% of phosphorus-nitrogen flame retardant and 10-20% of phosphate flame retardant. The component B comprises the following components in percentage by weight: 10-20% of polyetheramine curing agent D230, 50-70% of isophorone diamine (IPDA) and 20-30% of N-aminoethyl piperazidine. The component A and component B are mixed according to the weight ratio of 100:(19-21) to obtain the composition. On the premise of ensuring various physiochemical properties of the cured resin and especially the mechanical properties and halogen-free flame retardancy, the composition does not use any filler-type flame retardant, and satisfies the operating requirements for multiple techniques.
