Claim:
1. A method of manufacturing an epoxy resin composition for neutron shielding, comprising: obtaining a mixture of a curing agent and a powder by mixing an amine-based curing agent with a boron compound powder for neutron absorption and a powder containing a gamma ray attenuation, high density meta powder and a flame retardant powder; performing an ultrasonic wave treatment by applying ultrasonic waves to the mixture to coat a powder surface with the amine-based curing agent, simultaneously with allowing powder particles to be dispersed in the curing agent; and mixing the amine-based curing agent including the ultrasonic wave-treated and dispersed powder particles with an epoxy resin to then be dispersed, wherein the ultrasonic waves are applied by directly immersing an ultrasonic horn in the mixture including the amine-based curing agent, the boron compound powder, the high-density metal powder and the flame retardant powder mixed therein.
