Nuclear-radiation-protection yarn with temperature control function and production method thereof

Abstract

The invention belongs to the technical field of radiation protection and discloses nuclear-radiation-protection yarn with a temperature control function and a production method thereof. The productionmethod includes: subjecting core-shell-structured phase change microcapsules to surface modification, washing and filtering; blending the modified phase change microcapsules and polymer in deionizedwater, and performing solution spinning to produce phase change microcapsule-polymer composite fibers; doubling the change microcapsule-polymer composite fibers and radiation protection polymer composite fibers to form the nuclear-radiation-protection yarn with functions of neutron and gamma ray protection and temperature control. The nuclear-radiation-protection yarn can be further woven into nuclear-radiation-protection textile fabric and wearable nuclear-radiation-protection products and is promising in application prospect in fields such as nuclear operation and nuclear emergency. The novel preparation method is simple to operate, stable in process and low in cost.

Description

technical field [0001] The invention belongs to the technical field of nuclear radiation protection, and in particular relates to a nuclear radiation protection yarn with temperature control function and a preparation method thereof. Background technique [0002] Currently, the closest prior art: [0003] Nuclear radiation environment usually has many kinds of rays at the same time, such as α, β, γ-rays, X-rays, neutrons and protons, etc., which can cause biological cell damage, cancer and even gene mutation, which need to be effectively protected and controlled . Neutrons and gamma rays have different characteristics, and they are also the most difficult and harmful types of high-energy rays to protect against. However, the current commercial protective materials or products have only a single radiation protection function. [0004] Secondly, at present, wearable radiation protection products are mainly made of rubber materials, especially in the working environment of 40...

AI Technical Summary

Problems solved by technology

[0006] (1) In the prior art, radiation protection products have a single radiation protection function, either protecting neutrons or gamma rays, which cannot ensure the safety of radiation protection under nuclear radiation environmental conditions

[0007] (2) In the prior art, radiation protection products are mainly made of rubber, which has poor air permeability and moisture permeability, and the sweat secreted by the human body cannot be discharged in time, resulting in poor wearing comfort

[0008] (3) In the prior art, the temperature control performance of radiation protection products is poor, and the temperature difference between the inside and outside of the wearable products is small. When the ambient temperature is high, it is stuffy, and when the ambient temperature is low, it is cold, which will also affect the wearing comfort.
