Abstract
The invention provides an infrared stealth coating and a preparation method thereof, and a film forming method. The infrared stealth coating comprises a silver nanowire, a transparent organic substance, a dispersing agent and / or coloring filler, wherein the concentration of a silver nanowire dispersion is 1 to 60 mg / mL, and the dispersing agent corresponding to the silver nanowire dispersion is water or isopropyl alcohol; the transparent organic substance is one selected from the group consisting of polymethyl methacrylate, poly(4-methylpentene), polyethylene, polyethylene terephthalate, polyurethane and polystyrene ester, and different transparent organic substances correspond to different dispersing agents; a transparent organic substance dispersion has a mass fraction of 4% to 50%; thedispersing agent is an organic solvent and / or an inorganic solvent; and the coloring filler is an inorganic metal oxide and is one or more selected from the group consisting of phthalocyanine green, Cr2O3, Fe2O3 and NiO. The infrared stealth coating in the invention has high visible-light transmittance, high infrared reflectivity and low infrared emissivity, and has remarkable stealth effect.
Description
technical field [0001] The present disclosure relates to the field of infrared stealth materials, in particular, to an infrared stealth coating, a preparation method and a film-forming method thereof. Background technique [0002] Infrared radiation has a high transmittance in the atmosphere, especially in the 8-14 μm band, and objects in this band will have obvious infrared features. By reducing the infrared radiation characteristics of the target and reducing the difference in infrared radiation characteristics between the detected target and the complex environment, it can make it difficult for the detection system to find or reduce the detection effect of the detection system. According to the Stephen-Boltzmann law, it can be known that the infrared radiation energy of an object mainly depends on the surface temperature of the object and its infrared emissivity, and in a high-temperature environment, the surface temperature of the target object is the main factor affecti...
