Abstract

The invention discloses a water-based infrared camouflage coating as well as a preparation method and application thereof. The water-based infrared camouflage coating is prepared from the following raw materials in percentage: 0.1 to 1.0 percent of wetting dispersant, 0.05 to 0.5 percent of defoaming agent, 0 to 20 percent of nano cesium tungsten bronze powder, 0 to 20 percent of nano indium tin oxide powder, 10 to 30 percent of water-based aluminum silver paste, 30 to 50 percent of PU emulsion, 0.1 to 1 percent of sterilizing agent, 0.1 to 1 percent of thickening agent, 2 to 6 percent of phase change microcapsule, 1 to 4 percent of hollow glass bead and the balance of deionized water. The problem that most of existing infrared camouflage coatings are of a solvent type and do not meet the environmental protection requirement is solved. The coating prepared by the invention is applied to a wearable electrothermal film, so that the electrothermal film has an infrared stealth capability while providing cold-proof and warm-keeping functions through infrared electric heating.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a water-based infrared stealth coating and a preparation method and application thereof. Background technique [0002] In the severe cold environment in winter, individual operations (such as standing guard, patrolling, lurking, camping, etc.) often cause the temperature of the body and exposed parts to drop. Efficiency, and even life-threatening in severe cases. Products made with wearable electric heating film, such as infrared electric heating coats and hats, scarves, insoles, etc., can allow officers and soldiers to feel the warm experience brought by light and thin clothing in winter. [0003] All objects on the earth emit infrared radiation all the time, and infrared detection technology realizes the reconnaissance of the target by capturing infrared radiation energy. As a necessary means of military reconnaissance, infrared detection technology plays an indispe...
