Abstract
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.

A neutron shielding material composition comprising:
- a hydrogenated bisphenol resin;
- a refractory material having higher density than that of the hydrogenated bisphenol resin;
- a density-increasing agent having higher density than that of the refractory material;
- a curing agent component;
- a boron compound,
- wherein said neutron shielding material composition maintains the density of a base resin comprising said curing agent component and the refractory material;
- and
- wherein density of the neutron shielding material composition is from 1.62 g/cm3 to 1.72 g/cm3.
A neutron shielding material composition comprising a hydrogenated bisphenol epoxy represented by the following structural formula (1):
- wherein each of R1 to R4 is independently selected from the group consisting of CH3, H, F, Cl and Br, and n is from 0 to 2;
- a refractory material having higher density than that of the hydrogenated bisphenol resin;
- a curing agent component having at least one ring structure and a plurality of amino groups;
- a density-increasing agent having higher density than that of the refractory material;
- a boron compound,
- wherein said neutron shielding material composition maintains the density of a base resin comprising said curing agent component and the refractory material;
- and
- wherein density of the neutron shielding material composition is from 1.62 g/cm3 to 1.72 g/cm3.
