Problems solved by technology

[0003] Traditional γ / X-ray radiation protective clothing uses lead rubber as the main material, which is heavy, poor in flexibility, weak in radiation shielding ability and biologically toxic, and will gradually be eliminated; due to poor heat dissipation and airtightness of lead rubber protective clothing, poor wearing comfort; If the protective clothing itself has a radiation warning function, specific places can effectively remind radioactive practitioners that there is a radiation risk, and improve the effect of safety precautions

Abstract

The invention relates to the field of design and preparation of nuclear radiation protection materials, in particular to a flexible radiation protection material with functions of radiation warning and temperature adjustment and a preparation method of the flexible radiation protection material. The flexible radiation protection material is used for manufacturing radiation protection garments and is in a three-layer structure comprising a radiation warning layer, a radiation shielding layer and a temperature adjusting layer. The preparation method of the protection material which is processed layer by layer includes: firstly, forming the temperature adjusting layer, namely mixing and spraying room-temperature vulcanized silicon rubber and a phase-variable energy storage capsule material to release cloth, and blowing hot air for curing; secondly, mixing and spraying the room-temperature vulcanized silicon rubber and filler with a shielding function to the temperature adjusting layer, and blowing hot air for curing; finally, mixing and spraying the room-temperature vulcanized silicon rubber and a fluorescent powder material to the radiation shielding layer, and blowing hot air for curing. The flexible radiation protection material is excellent in flexibility and gamma-ray / X-ray shielding performance and has the functions of radiation warning and temperature adjustment, thereby being an excellent core material for novel radiation protection garments.

Description

Technical field: [0001] The invention relates to a flexible radiation protection material with radiation warning and temperature regulation and a preparation method thereof, belonging to the field of nuclear radiation protection and the technical field of preparation of nuclear radiation shielding materials. Background technique: [0002] As the application of nuclear technology plays an increasingly important role in radiation processing, medical diagnosis and national defense and military affairs, the number of radiation practitioners also increases accordingly. However, while the development of nuclear technology brings applications to people, various rays also bring harm to people to a certain extent. Therefore, it is necessary to reduce the occupational exposure level of employees in various radioactive activities and ensure the life and health of radiation employees. extremely important. [0003] Traditional γ / X-ray radiation protective clothing uses lead rubber as th...
