Problems solved by technology

[0004]In the field of military stealth, the research focus has been on low-emissivity materials, especially low-emissivity coatings, which are mainly made of aluminum powder and brass powder. Low-emissivity materials are infrared absorbers and have the following disadvantages: Coatings are poorly resistant to contamination, dust and moisture can significantly increase their emissivity
Therefore, the application of low-emissivity coatings has been greatly restricted
Low-emissivity infrared stealth materials are incompatible with camouflage of visible light, especially radar bands, and the coating has poor tolerance to pollution. Dust and moisture can significantly increase the emissivity and reduce the stealth effect

Description

[0001] technical field [0002] The invention relates to the technical field of coatings, in particular to a stealth coating material and a preparation method thereof. Background technique [0003] The propagation of infrared radiation in the atmosphere follows the laws of refraction, reflection, absorption, and scattering of visible light, and has the general physical characteristics of light. Its transmission ability in the atmosphere is related to the content of water and carbon dioxide in the atmosphere. When an object emits infrared radiation, the water and carbon dioxide in the atmosphere will absorb the radiation of a certain band and attenuate the infrared radiation signal of this band. Especially moving targets, such as airplanes, tanks, warships and missile loading vehicles, all have high-power power sources, which will generate strong thermal infrared radiation when moving. Some high-speed moving targets, such as airplanes, missiles, etc., are also sources of the...
