Abstract

This application provides a preparation method of core-shell structure tungsten / gadolinium oxide functional fiber for X, gamma ray protection, first prepare core-shell structure tungsten / gadolinium oxide powder; prepare W@Gd according to the above powder 2 o 3 / PP blended melt; then prepare W@Gd according to the above blended melt 2 o 3 / PP composite fiber. The core-shell structure tungsten / gadolinium oxide functional fiber prepared according to the method can play a synergistic protective role in radiation protection, eliminate weak protection areas and effectively absorb secondary radiation generated by radiation. Secondly, the prepared functional fibers are lead-free and lightweight, and have good application prospects in X and γ-ray radiation protection.

Description

Preparation of a core-shell structure tungsten / gadolinium oxide functional fiber for X, γ-ray protection method Technical field: The application relates to radiation protection field, relate in particular to a kind of X, gamma ray protection with core-shell structure tungsten / gadolinium oxide function Fiber preparation method. Background technique: The development of nuclear technology brings convenience to people and also produces a lot of radiation hazards, which are light, flexible and protective. Textiles with excellent radiation protection are the focus of current research. Radiation protection materials are mainly divided into lead-containing materials and lead-free materials. kind. Lead is mainly based on lead. Although the protective effect is excellent, it is toxic, has poor strength and has a large scattering of low-energy X-rays. Lead-free materials mainly include composite materials made of rare earth elements and heavy metal compounds such as tin, tu...
