Embodiment 1

[0053] Embodiment 1, preparation khaki stealth paint

[0054] At room temperature, weigh 24 parts of iron oxide yellow pigment, 1 part of protective colloid (sodium alginate), 5 parts of functional filler copper powder (particle size: 800 mesh), 10 parts of adhesive polyacrylate (molecular weight: 15000) , 60 parts of deionized water, after mixing and stirring for 3 hours at a speed of 3000 rpm under normal temperature and pressure, the low-emissivity coating T1 was obtained, and the IR-2 dual-band emissivity measurement developed by the Shanghai Institute of Physics and Technology, Chinese Academy of Sciences was used. The emissivity measured by the instrument is 0.72.

[0055] The visible light-near-infrared reflectance test result of the polyester / cotton blended fabric coated with the coating prepared in this embodiment is as follows: figure 1 As shown in the curve A in the middle, it can be known that the reflectance of the fabric increases gradually in the 400-900nm band...

Abstract

The invention discloses an infrared low-emissivity earthy yellow camouflage coating and a preparation method of the infrared low-emissivity earthy yellow camouflage coating. The infrared low-emissivity earthy yellow camouflage coating comprises the following components in parts by mass: 10 to 30 parts of a yellow pigment, 1 to 5 parts of a protective colloid, 5 to 20 parts of a functional filler, 5 to 30 parts of an adhesive and 10 to 50 parts of water. The infrared low-emissivity camouflage coating provided by the invention has infrared low emissivity of 0.56 to 0.72 under the wavelength of 8 to 14 microns, and basically meets an infrared camouflage requirement. The color of the infrared low-emissivity camouflage coating provided by the invention is earthy yellow which is one of basic colors of visible light camouflage. A good visible light near-infrared multi-band camouflage compatible effect is achieved.

Description

technical field [0001] The invention relates to an earth-yellow 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 i...
