Abstract

The invention discloses a low-infrared- emissivity green stealth paint. The stealth paint comprises, by weight, 10-30 parts of a green pigment, 1-5 parts of a protective colloid, 5-20 parts of a functional filler, 5-30 parts of an adhesive, 2-10 parts of a toner, and 10-50 parts of water. The stealth paint provided by the invention has a low infrared emissivity, and has an infrared emissivity between 0.65 and 0.76 at a wavelength of 8-14 micron. The stealth paint basically meets requirements of infrared stealth. The color of the stealth paint provided by the invention is green that is one of the primitive colors of visible light camouflage. The stealth paint has compatible stealth effects at multi-wavelength from visible light to near infrared.

Description

technical field [0001] The invention relates to a green stealth paint with low infrared emissivity and a preparation method thereof, belonging to the field of textile material science. Background technique [0002] Infrared light (line) is an electromagnetic wave with a wavelength of 0.7-1000 μm. From a physical point of view, objects with a surface temperature above absolute zero will radiate to the outside world in the form of infrared rays. Due to the existence of water vapor, dust and other impurities in the atmosphere, most of the infrared rays in the band will be reflected, absorbed and scattered. However, in the following three bands: 1-2.5 μm, 3-5 μm and 8-14 μm, the infrared transmittance is relatively high and basically transparent, commonly known as the atmospheric window. Among them, the infrared radiation of 3~5μm and 8~14μm is the thermal radiation caused by the temperature of the target and the background itself. Infrared detection in the military is mainly...
