Preparation of SBR Rubber Based Flexible Shield Material

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 good shield characteristics, and high toughness and structure adaptability.
