Visible/near-infrared hyperspectral camouflage coating, and preparation method and application thereof

Abstract

The invention discloses a visible / near-infrared hyperspectral camouflage coating as well as a preparation method and application thereof, wherein thevisible / near-infrared hyperspectral camouflage coating is a water-based system coating prepared from water-based resin, a water-absorbing and water-retaining agent, a network skeleton, color paste and a water-based coating additive, and the water-based coating additive comprises at least one additive of a dispersing agent, a thickening agent and an antibacterial agent. After absorbing water, the camouflage coating can simulate visible and near-infrared spectra emitted or reflected by the surface of a plant, has the same color and spectrum as the background of the plant, and has visible near-infrared hyperspectral camouflage capacity. According to the invention, the camouflage coating is prepared by uniformly stirring and mixing water-based resin, a water-absorbing and water-retaining agent, a network skeleton, color paste, a water-based coating additive and water in proportion. The coating is applied to the surface of a base material to prepare a visible near-infrared camouflage coating, has a visible near-infrared hyperspectral camouflage function after absorbing water, and can be widely applied to camouflage protection in the fields of military equipment, command places, radar communication and the like.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a bionic hyperspectral camouflage coating and a coating preparation method thereof. Background technique [0002] With the continuous development of advanced guided weapons, modern warfare has entered the "find and destroy" war mode. By developing multi-band detection technology, military powers in the world can realize reliable detection of long-distance targets, long-range early warning and target tracking. On the one hand, camouflage technology can be used as an effective means to improve defense penetration, especially in-depth strike capabilities, and on the other hand, it is also an important means to protect the survivability of one's own important facilities and weapon systems, and has been highly valued by countries all over the world. [0003] The emergence of hyperspectral remote sensing detection technology has greatly increased the difficult...

Problems solved by technology

Early patent application CN201010287908.7 only focused on research on hyperspectral camouflage and its corrosion resistance, interfered with hyperspectral detection as much as possible, and could not simulate background spectrum

In recent years, the patent applications CN202010145573.9 and CN201811286034.6 are really related to the hyperspectral camouflage by simulating the spectrum of plant leaves in the 400-2500nm spectral range in the visible and near-infrared bands, but they do not give the actual simulation effect
