Flexible material with nuclear radiation protection and electromagnetic shielding functions, and preparation method and application thereof

Abstract

The invention discloses a flexible material with nuclear radiation protection and electromagnetic shielding functions, and a preparation method and application thereof. The flexible material comprisesfour functional layers, namely an electromagnetic radiation absorption layer, a first ray radiation shielding layer, a neutron radiation shielding layer and a second ray radiation shielding layer insequence from outside to inside, wherein each functional layer comprises a polymer base material and a functional filler. According to the flexible composite gradient material, lead powder is not added; the defects that a traditional homogeneous blending material is limited in functional filler filling amount, easy to disperse unevenly, low in material comprehensive performance and the like are overcome; and meanwhile, the weak absorption region of elemental lead in an energy interval of 40-88 keV can be effectively compensated by adopting a compounding ratio of the functional filler, so the material has excellent X-ray, gamma-ray and neutron radiation shielding performance and electromagnetic radiation absorption performance.

Description

technical field [0001] The invention belongs to the field systems of nuclear radiation protection and electromagnetic shielding (that is, stealth function), and in particular relates to a flexible material and a manufacturing method which have both nuclear radiation shielding and electromagnetic radiation absorption. Background technique [0002] With the rapid development of modern military weapons and equipment technology, the battlefield environment in the future will also become complex. Both traditional nuclear weapons and electromagnetic pulse weapons as new concept weapons may appear on the battlefield. The resulting nuclear and electromagnetic radiation will not only It will cause interference and damage to electronic instruments and equipment in weapons and equipment, affect their normal work, and also cause serious harm to the health of personnel. At present, the existing nuclear radiation protection materials on the market cannot meet the requirements of electroma...
