摘　　要：采用耐辐照高苯丁苯橡胶替代不耐辐照的硅橡胶做基体,通过密炼(或开炼)工艺,利用合理的多组添加剂改善胶料的理化性能,并用混炼工艺将铅粉或碳化硼粉均匀弥散在丁苯橡胶基体中。此类材料可任意塑形,不仅有着良好的屏蔽性能,而且具有极好的韧性和结构适应性。SBR flexible shielding material is used for the first time in high benzene content forth benzene rubber with radiation resistance instead of silicon rubber that is not radiation resistant. By dense refine （or opening refine） process, the reasonable multiple group additive is adopted to improve the physical and chemical characteristics, and the mixing refine process is used to disperse the lead powder and boron carbide powder in forth benzene rubber uniformly. This kind of material can be arbitrarily plastic formation, with ~ood shield characteristics, and hiKh touahness and structure adaptability.
