COMPOSITION FOR NEUTRON SHIELD MATERIAL, SHIELD MATERIAL AND CONTAINER

摘要

A neutron shield material that exhibits high heat resistance and ensures neutron shielding capacity. A composition for neutron shield material excelling in heat resistance and ensuring neutron shielding capacity is provided by comprising a hydrogenated bisphenol type epoxy of the formula: (1) (wherein each of R1 to R4 is independently selected from the group consisting of CH3, H, F, Cl and Br, and n = 0 to 2), a hardening agent component having at least one cyclic structure and two or more amino groups, a density increasing agent and a boron compound.
