Multilayered radiation shielding thin-film composite materials made by uniform or multi-sized non-leaded tungsten particles on which polymers were synthesized for uniform dispersion of the particles in the same polymer or compatible polymer

摘要

The present invention relates to a multi-layered radiation shielding material for maximizing shielding performance and a method of manufacturing the same, and more particularly to a multi-layered radiation shielding material for shielding a polymer chain on a surface of a metal powder (tungsten) having a multi- It is possible to disperse tungsten particles uniformly by mixing with a miscible polymer resin and to prevent the formation of pinholes and to laminate these shielding materials in multiple layers or to bond them with a blue stencil sheet without using toxic substances such as lead To a multi-layered composite radiation shielding material which maximizes radiation shielding performance through a laminated structure and a method for manufacturing the same.
