Hyperspectral stealth coating, preparation method thereof and hyperspectral stealth coating layer

Abstract

The invention relates to a hyperspectral stealth coating. The coating comprises, by mass, 40-50% of an adhesive, 14-17.5% of a pigment filler, 0-20% of a functional filler, 0.5-1% of an assistant and14-18% of an organic solvent. The hyperspectral stealth coating and the coating layer have excellent hyperspectral reconnaissance prevention performance; in 0.4-2.5 [mu]m, the ratio of the average value of the near-infrared (710-880 nm) reflectivity of the hyperspectral stealth coating to the average value of the reflectivity of the red light region (620-660 nm) is greater than 5; the reflectivityrange of the spectral reflectivity at 1200 nm is 40-60%; the reflectivity at 1400 nm is 30-50%; the reflectivity at 1800 nm is 20-40%; the reflectivity range at 2500 nm is 0-20%; the 60 DEG gloss ofthe hyperspectral stealth coating is smaller than 5 gloss units; and the national military standard requirement is met, the hyperspectral reconnaissance resistance stealth performance which a traditional stealth material does not have is achieved, and the confrontation waveband is expanded to 0.4-2.5 [mu]m. In addition, the invention also relates to a preparation method of the hyperspectral stealth coating, and a hyperspectral stealth coating layer.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a hyperspectral stealth coating, a preparation method thereof and a hyperspectral stealth coating. Background technique [0002] In modern high-tech warfare, the discovery of a target means its destruction, especially under all-weather, full-time reconnaissance conditions dominated by satellites, early warning aircraft, unmanned aerial vehicles, and high-altitude and high-speed reconnaissance aircraft. Under various strike methods such as smart bombs, ground military targets are faced with extremely severe battlefield survival conditions. [0003] In recent years, the mature application of new military reconnaissance technologies represented by hyperspectral and hyperspectral imaging detection has seriously threatened the battlefield survivability and penetration capabilities of various ground military targets. This type of detection technology combines ...

AI Technical Summary

Problems solved by technology

This type of detection technology combines the advantages of spectral analysis and imaging remote sensing. It can detect and identify targets by detecting the difference information between the target and the inherent spectral characteristics of the background. Therefore, it still has a strong ability to identify camouflaged targets that cannot be detected by traditional optical reconnaissance techniques. , its reconnaissance spectrum covers 0.4-2.5μm, the spectral resolution can reach 10nm, and the number of bands can reach more than 200. With the development of technology, its reconnaissance accuracy and efficiency will be further improved. Methods, materials and equipment all pose serious challenges
