Abstract
(EN)
Disclosed in the present invention are a lightweight and highly elastic wave-absorbing material and a preparation method therefor. The lightweight and highly elastic wave-absorbing material comprises a base layer and a flexible wave-absorbing layer which are arranged in sequence. The flexible wave-absorbing layer comprises an aqueous resin, a wave-absorbing filler, an organic wetting dispersant and deionized water. By applying the technical solution of the present invention, using an aqueous resin and a flexible fabric, etc., an environmentally friendly wave-absorbing material having low surface density, high elasticity and no contamination is developed, the elasticity of the wave-absorbing material is greatly improved, and scope of application thereof is expanded. The wave-absorbing material of the present invention can be applied to radar stealth of equipment, can significantly improve the stealth performance of target equipment under high-frequency radar, and can be directly coated on the equipment surface. As the wave-absorbing material can be used for flexible substrates, it can also be made into stealth tarpaulins, car covers, tents, etc. for stealth and camouflage of ground targets.

La présente invention concerne un matériau absorbant les ondes léger et hautement élastique et un procédé de préparation associé. Le matériau absorbant les ondes léger et hautement élastique comprend une couche de base et une couche d'absorption d'ondes flexible qui sont agencées en séquence. La couche d'absorption d'ondes flexible comprend une résine aqueuse, une charge d'absorption d'ondes, un dispersant de mouillage organique et de l'eau désionisée. Par l'application de la solution technique selon la présente invention, au moyen d'une résine aqueuse et d'un tissu flexible etc., un matériau absorbant les ondes respectueux de l'environnement présentant une faible densité de surface, une élasticité élevée et aucune contamination est développé, l'élasticité du matériau d'absorption d'ondes est considérablement améliorée et sa portée d'application est étendue. Le matériau absorbant les ondes selon la présente invention peut être appliqué à la furtivité radar d'un équipement, peut améliorer considérablement les performances de furtivité de l'équipement cible dans un radar à haute fréquence et peut être directement revêtu sur la surface de l'équipement. Étant donné que le matériau absorbant les ondes peut être utilisé pour des substrats flexibles, il peut également être réalisé sous la forme de bâches, de housses de voiture et de tentes furtives pour la furtivité et le camouflage de cibles au sol.
