Preparation method for nuclear radiation shielding material

The invention discloses a preparation method for a nuclear radiation shielding material. On the basis of selected material samples, according to each component's content calculated by an optimized design method, and directed at the characteristics of the studied shielding composite material, a specific preparation process is determined. The process falls into four stages in time order: material preparation, curing pretreatment, material curing, and demoulding. The shielding material shielding different energy and different flux neutron-gamma mixed fields can meet the requirements of best shielding effect, excellent mechanical and thermal performance, and good anti-radiation performance. The technological method provided by the invention can realize curing molding of the material at room temperature, and is easy to realize mass production. The shielding material has the optimal shielding effect, is convenient to implement transportation engineering, and is economical and practical.
