[0002] Infrared detection is becoming more and more common in modern military reconnaissance and surveillance. All military targets are under the threat of infrared. For example, some military tanks, aircraft, warships, etc. will generate a large amount of thermal infrared radiation when they are in motion. Therefore, there are many camouflage Coatings are applied to military equipment such as tanks, aircraft, and warships. Traditional camouflage coatings use pigments to reduce the infrared emissivity, and often need to add a large amount of metallic pigments, which will cause problems such as the coating is prone to settlement; It will be affected by the sound of different frequencies and intensities from the outside world and its own equipment, which will affect human health and work efficiency, and is also not conducive to the life and structural safety of military targets. Military targets must also have corrosion resistance and salt spray performance when used

[0003] At present, there are few reports on sound-absorbing and noise-reducing, salt spray-resistant, and infrared invisible materials.
