| description | The invention discloses a neutron gamma composite shielding material and a preparation method thereof. According to the neutron-gamma composite shielding material, samarium oxide of a micron plate structure serves as a neutron and gamma ray absorbent, boron carbide serves as a neutron absorbent, and high-density polyethylene serves as a base material. The samarium oxide filler with the micro-plate structure has a high specific surface area, so that the probability of interaction with neutron gamma rays can be increased, and the neutron gamma shielding capability of the composite material is improved. In addition, by adopting preparation processes such as high-energy ball milling and internal mixing, the clustering of the inorganic filler in the matrix is reduced, and the interfacial compatibility between the inorganic filler and the polymer matrix is improved. The neutron-gamma composite shielding material containing the samarium oxide with the micro-plate structure, disclosed by the invention, has relatively |
