以我国特有的含硼矿物经选矿后得到的含硼铁精矿粉作为中子吸收体与低粘度环氧树脂E51相复合,制备了一种低成本含硼铁精矿粉/环氧树脂复合屏蔽材料.测试了这种复合材料对慢中子和60Co γ射线的屏蔽性能,确定了满足射线屏蔽性能的含硼铁精矿粉与树脂的最佳配比范围.证明了以含硼铁精矿粉作为原料制备复合射线屏蔽材料是可行的.结果表明,3种配比的复合屏蔽材料其慢中子宏观截面均超过了宏观截面为Σ=0.158cm-1,以B4C为中子吸收体的铅硼聚乙烯屏蔽材料B201.此复合屏蔽材料的宏观截面最大值为Σ=0.1882cm-1,具备较好的慢中子屏蔽能力;对60Co γ射线的线性减弱系数最大值为μ=0.0772cm-1,屏蔽性能介于水和混凝土之间.
