Abstract

The invention discloses a self-adaptive thermal camouflage coating, which is located on a substrate, and is mainly formed by a vanadium dioxide coating, a tungsten-doped vanadium dioxide coating and a low-emissivity coating. A preparation method of the self-adaptive thermal camouflage coating provided by the invention comprises the steps of (1) preparing vanadium dioxide ink, tungsten-doped vanadium dioxide ink and low emissivity ink; (2) depositing the vanadium dioxide ink, the tungsten-doped vanadium dioxide ink and the low emissivity ink on the surface of the substrate through a spray ink printing method according to designed camouflage patterns, and obtaining a layer of self-adaptive thermal camouflage coating on the surface of the substrate. According to the self-adaptive thermal camouflage coating provided by the invention, the self-adaptive thermal camouflage coating is prepared by adopting vanadium dioxide nano-powder with a thermotropic infrared emittance characteristic, tungsten-doped vanadium dioxide nano-powder and low emissivity silver powder, so that the camouflage patterns can be changed with the temperature change accordingly, and an infrared camouflage effect is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of camouflage and stealth, and in particular relates to an adaptive thermal camouflage coating and a preparation method thereof. Background technique [0002] With the rapid development of infrared technology, weapons, equipment and personnel on the battlefield are increasingly threatened by infrared detection and infrared guidance strikes. In order to improve the survivability and combat effectiveness of the battlefield, infrared stealth measures must be taken. The recognition of targets based on infrared detection equipment or infrared guided weapons is mainly based on the difference between the infrared radiation intensity of the target and the background. Infrared camouflage can divide and distort the infrared heat map of the target through coatings with different infrared emissivity gradients, so that the target’s The infrared heat map is deformed to achieve the fusion of the target and the background. ...
