Problems solved by technology

However, the reflectance spectrum of common visible-near-infrared camouflage coatings commonly used at present is only similar to or the same as that of green vegetation in the 400-1100nm band, while the infrared light reflectance in the 1100-1300nm band is relatively low.
The camouflage effect of ordinary visible light-near infrared camouflage paint cannot match the detection range of 400-2500nm with the increasing modern detection technology
In addition, commonly used ordinary visible-near-infrared camouflage paints are all colored with chrome yellow pigments. The hexavalent chromium in the paint will cause serious harm to the human body and cause serious environmental pollution. Require

Abstract

The invention relates to environment-friendly paint simulating a hyperspectrum of green vegetation and a preparation method of the environment-friendly paint. A component B of the paint comprises the following ingredients in percentage by mass: 30-45% of fluorocarbon resin, 10-30% of special pigment, 10-25% of filling, 1-8% of dispersing agent, 0.1-1% of flatting agent, 1-5% of matting agent, 0.01-0.3% of drier and 15-25% of mixed solvent; the special pigment comprises the following ingredients in percentage by mass: 1-13% of rutile titania, 1-8% of 1,4 diketopyrrolopyrrole organic red pigment, 0-4% of inorganic cobalt blue, 2-20% of benzimidazolone organic yellow pigment, 17-60% of green pigment and 10-75% of black pigment; a component A is aliphatic polyisocyanate; and a mass ratio of the component A to the component B is 1:14. The paint has good film coating luster, corrosion resistance and weather resistance, is free from hexavalent chromium, and an effective hyperspectrum (400-1300nm) scope has a specific reflection spectrum characteristic of the green vegetation.

Description

technical field [0001] The invention relates to an environment-friendly paint for simulating hyperspectral green vegetation and a preparation method thereof. Background technique [0002] The paint that simulates the spectrum of green vegetation is a paint that reduces the degree of recognition of the painted object by simulating the natural green background. Due to the advancement of modern remote sensing detection technology, especially hyperspectral imaging technology, the camouflage effect of camouflage coatings used for important facilities and equipment has become increasingly demanding. The reflection characteristic spectrum of the camouflage paint film must have the "green reflection peak" of green vegetation in the 550nm band, the "red edge" formed by the steep rise of the reflectance in the 680-780nm band, and the "reflection rate of 40% or more" in the 780-1300nm band. The characteristic spectrum of the near-infrared plateau". However, the reflectance spectrum o...
