Boron Carbide Containing Paint Absorbing and Shielding Neutron Radiation

对碳化硼(B4C)/环氧树脂涂料合成工艺进行研究,制得一种以793树脂作为固化剂的能屏蔽和吸收中子辐射的涂料.对B4C/环氧树脂涂料的成膜条件及不同含量B4C涂料的硬度、抗冲击性、附着力和柔韧性等物理机械性能进行测试研究.结果表明,含有30%B4C的环氧树脂涂料的总体机械性能最佳.在此基础上,考察了不同涂膜厚度下B4C/环氧树脂涂料的防中子辐射的性能,薄膜厚度超过300,μm时,可以有效屏蔽中子射线.

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.
