Boron Carbide Containing Paint Absorbing and Shielding Neutron Radiation

The synthesis technology of boron carbide(B4C)/epoxy resin paint was investigated,and the paint with the ability of absorbing and shielding the neutron radiation,solidified by 793 resin,was obtained.The film-forming conditions of B4C / epoxy resin paint were treated;meanwhile,the relationship between the different contents of B4C in the paint and hardness,impact resistance,adhesion,flexibility and other physical testing of mechanical properties was studied.The conclusion was obtained that the overall machinery of B4C/epoxy paint has better per-formance with 30% B4C.Furthermore,The anti-neutron radiation performance of B4C/epoxy paint with different film thicknesses was also examined.Results show that effective neutron radiation shielding can be achieved when the film thickness exceeds 300 μm.
