EPOXY RESIN COMPOSITION FOR NEUTRON SHIELDING, AND METHOD FOR PREPARING SAME

摘要

The present invention relates to an epoxy resin composition including a nano-sized radioactive radiation shielding material and having good superior shielding effects for against radiation, and to a method for preparing same. ParticularlyIn particular, the present invention relates to a method for preparing the epoxy resin composition for neutron shielding, comprising the steps of: a step of mixing a boron compound powder for absorbing neutrons, optionally a high density metal powder for shielding from against gamma rays and a flame retardant powder, respectively separately or in combination, with an amine-based curing agent to obtain a mixture of a curing agent and a powder; an ultrasonic wave treating step of applying ultrasonic waves to the mixture to coat the surface of the powder with the amine-based curing agent and to disperse the powder in the curing agent; and a dispersing step of mixing and dispersing the amine-based curing agent, that was dispersed and includes the powder treated with ultrasonic waves, in an epoxy resin.
