Abstract

The invention discloses a flexible radiation-prevention fiber material and a preparation method thereof, is mainly used for the field of ionizing radiation shielding and protection, has the characteristics of high shielding and protecting efficiency, excellent mechanical property and the like, and belongs to the technical field of novel functional high polymer materials. The main preparation process comprises the following steps: 1) uniformly mixing a thermoplastic resin carrier, functional powder, a coupling agent, a dispersing agent and an antioxidant, and then extruding and granulating viadouble screws to obtain functional masterbatches for spinning; and 2) blending, fusing and spinning the functional masterbatches and different thermoplastic resins according to difference of types ofthe thermoplastic resin carriers, or directly fusing and spinning the functional masterbatches to prepare a novel fiber material which has a protection function on ionization radiation. A selecting range of a fiber carrier is expanded by controlling a processing technological course, and thus, the functionalization effect of a flexible shielding fiber material is outstanding.

Description

technical field [0001] The invention relates to the technical field of novel functional polymer fiber materials, in particular to a flexible anti-radiation fiber material and a preparation method thereof. Background technique [0002] With the development of modern science, various high-energy rays are widely used in various fields such as military affairs, communications, medicine, and daily life, bringing benefits to the development of the economy and society, and also leading to the annual collective effective radiation dose in the world. Dose increase. For this reason, the safety protection problems brought by the ionizing radiation produced by high-energy rays have been paid more and more attention by people. [0003] Radiation rays are the flow of microscopic particles released during the transformation of atomic nuclei from one structure or one energy state to another structure or another energy state, including charged particles such as α and β protons and indirectl...
