Problems solved by technology

[0003] The existing radiation-proof fiber masterbatch materials are mainly aimed at non-ionizing radiation, such as absorbing electromagnetic radiation, ultraviolet radiation, etc., and cannot meet the protection against ionizing radiation produced by high-energy rays in the nuclear industry.
At the same time, the radiation protection functional masterbatches reported so far mainly achieve the protection function against ionizing radiation by mixing with thermoplastic resin carrier materials with moderate viscosity and melt spinning, which limits the amount of masterbatches added and reduces the radiation protection function. effective content of the material and thus also adversely affect the protective efficiency of the functional material
