Abstract

The invention discloses wave-absorbing camouflage cloth and a preparation method thereof, and particularly relates to the technical field of wave-absorbing materials, and the wave-absorbing camouflage cloth comprises a non-woven fabric, a wave-absorbing agent, an adhesive and an organic solvent. According to the invention, the combination effect of the wave-absorbing material and the matrix can be effectively enhanced, and it can be effectively ensured that the wave-absorbing camouflage cloth can still maintain a good external structure and a good wave-absorbing function after long-time high-intensity illumination and long-time soaking in an acid-base solution; polyacrylonitrile and silver nitrate are subjected to ultrasonic, electrostatic spinning and microwave treatment to form nano-silver particles, and meanwhile, the flame-retardant and antibacterial properties of the wave-absorbing camouflage cloth can be effectively enhanced; the oxidized nanocellulose is doped into the adhesive and is coated on the surface of the non-woven fabric, so that the steam barrier property and the grease resistance can be effectively enhanced; graphene, hollow silicon carbide spherical nanoparticles, multi-walled carbon nanotubes, nano-silver particles, epoxy resin and hollow microspheres are mixed, so that the wave-absorbing performance, stability, aging resistance and corrosion resistance of the wave-absorbing camouflage cloth can be further enhanced.

Description

Technical field [0001] The present invention relates to the field of absorbing materials, and more particularly, the present invention relates to an absorbent camouflage cloth and a preparation method thereof. Background technique [0002] The absorbing material refers to a type of material that can absorb or significantly reduce the electromagnetic wave energy received by its surface, thereby reducing the interference of electromagnetic waves. In engineering applications, the absorbing material is required to have high absorption rates in a wide frequency band, while also requires light, temperature, temperature resistant, resistance, corrosion resistance. With the development of modern science and technology, the effects of electromagnetic radiation on the environment are increasing; magnetic radiation passes through thermal effects, non-thermal effects, accumulation effects to the human body directly and indirectly; the absorbing material is designed, and two problems should b...
