第 44 卷 第 7 期 天 津 大 学 学 报 Vol.44 No.7 2011 年 7 月 Journal of Tianjin University Jul. 2011 ▋ 含碳化硼的吸收和屏蔽中子辐射涂料的研究 黄益平，冯惠生，梁 璐，徐 姣，张卫江 (天津大学化工学院，天津 300072) 摘 要 ：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 B C/环氧树脂涂料的成膜条件及不同含量 B C 涂料的硬度、抗冲击性、附着力和柔韧性等物理机械性 4 4 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． 关键词 ：碳化硼；环氧树脂；屏蔽中子辐射；涂料 中图分类号：TL7 ；TQ630.6 文献标志码 ：A 文章编号 ：0493-2137 (2011)07-0639-06 Boron Carbide Containing Paint Absorbing and Shielding Neutron Radiation HUANG Yi-ping ，FENG Hui-sheng ，LIANG Lu ，XU Jiao ，ZHANG Wei-jiang (School of Chemical Engineering and Technology ，Tianjin University ，Tianjin 300072 ，China) The synthesis technology of boron carbide (B C)/epoxy resin paint was investigated ，and the paint with Abstract ： 4 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 wit
