Abstract

The invention discloses a visible / infrared compatible self-adaptive camouflage coating. The visible / infrared compatible self-adaptive camouflage coating is in a layered structure and sequentially comprises a base layer, a bottoming layer, a thermal induced infrared emissivity layer and a camouflage pattern layer from inside to outside, wherein the thermal induced infrared emissivity layer is a vanadium dioxide layer. A preparation method of the visible / infrared compatible self-adaptive camouflage coating comprises the following steps: choosing a material of the base layer, coating a bottoming coating on the base layer, obtaining the bottoming layer on the base layer, and using a thermal induced infrared emissivity coating to prepare the thermal induced infrared emissivity layer on the bottoming layer through a coating process; arranging a camouflage pattern on the thermal induced infrared emissivity layer, using an ink-jet printer to print printing inks in different colors on the thermal induced infrared emissivity layer so as to obtain the camouflage pattern layer, and finishing the preparation of the visible / infrared compatible self-adaptive camouflage coating. The vanadium dioxide nano-coating with the thermochromism characteristic and a dye being high in tinting strength are adopted to realize the visible / infrared compatible self-adaptive camouflage performance.

Description

technical field [0001] The invention relates to the technical field of camouflage and stealth materials, in particular to a visible / infrared compatible adaptive camouflage coating and a preparation method thereof. Background technique [0002] In informationized local wars under high-tech conditions, in order to improve the battlefield survivability of weapons and equipment, camouflage and stealth of weapons and equipment is an effective way to reduce the probability of being discovered and enhance its attack effectiveness. In modern high-tech warfare, the combat area changes frequently, requiring troops to have a high degree of mobility, which requires that the camouflage and stealth equipment of various military equipment have good environmental adaptability, and can realize photoelectric characteristics as the region, time and season change. The controllable adjustment enables it to blend with the background under various conditions, and has good camouflage protection per...
