Abstract

The invention provides a preparation method of an anti-near-infrared camouflage coating, comprising: (1) dispersing PVP, chromium salt, cobalt salt, and cerium salt into an organic solvent to form a transparent and uniform nanofiber spinning solution; (2) The nanofiber spinning solution is electrospun, calcined at high temperature, crushed and sieved to obtain chromium-cobalt composite oxide nanofibers doped with cerium ions, and the chromium-cobalt composite oxide nanofibers doped with cerium ions prepared by the present invention have strong It can be used as a special pigment for anti-near-infrared camouflage coatings.

Description

technical field [0001] The invention belongs to the field of novel coatings, and in particular relates to a preparation method of an anti-near-infrared camouflage coating. Background technique [0002] Anti-near-infrared camouflage coating is mainly developed for the detection capability of modern optical reconnaissance equipment in the wavelength range of 380nm to 1100nm. It is a coating that can simulate the optical performance of camouflaged targets and background environments, thereby reducing the detectability of camouflaged targets. With the modernization of weapons and equipment and the development and improvement of near-infrared reconnaissance equipment, the threat of near-infrared reconnaissance to camouflaged targets is increasing. At present, the armies of most countries are equipped with various near-infrared reconnaissance equipment to varying degrees, such as intensifiers, starlight mirrors, infrared night vision devices, night vision goggles and other devices...
