Embodiment 1

[0053] Example 1. Preparation of 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 of 800 mesh), and 10 parts of binder polyacrylate (molecular weight of 15000) , 60 parts of deionized water, mixed and stirred at a speed of 3000 rpm under normal temperature and pressure for 3 hours to obtain a low emissivity paint T1, which uses the IR-2 dual-band emissivity measurement developed by the Shanghai Institute of Physics and Technology, Chinese Academy of Sciences The measured emissivity of the instrument is 0.72.

[0055] The visible light-near infrared reflectance test results of the polyester / cotton blended fabric coated with the coating prepared in this example are as follows figure 1 As shown by the middle A curve, it can be seen that the reflectivity of the fabric gradually increases in the 400-900nm band, and the reflectivity rema...

Embodiment 2

[0057] Example 2. Preparation of khaki stealth paint

[0058] At room temperature, weigh 15 parts of iron oxide yellow pigment, 5 parts of titanium nickel yellow pigment, 2 parts of protective colloidal cellulose ether (carboxymethyl cellulose), 5 parts of functional filler aluminum powder (particle size of 400 mesh), copper 8 parts of powder (with a particle size of 1000 mesh), 15 parts of polystyrene as a binder (molecular weight of 18000), and 50 parts of deionized water. After stirring for 3.5 hours at 3500 rpm under normal temperature and pressure, a low The emissivity paint T2 is 0.65 using the IR-2 dual-band emissivity measuring instrument developed by the Shanghai Institute of Physics and Technology of the Chinese Academy of Sciences.

[0059] The visible light-near infrared reflectance test results of the polyester / cotton blended fabric coated with the coating prepared in this example are as follows figure 1 As shown by the middle B curve, it can be seen that the reflecta...

Embodiment 3

[0061] Example 3: Preparation of khaki stealth paint

[0062] At room temperature, weigh 5 parts of titanium nickel yellow pigment, 10 parts of iron oxide yellow pigment, 5 parts of protective colloidal synthetic polymer thickener (polyvinyl alcohol), 15 parts of functional filler flake copper powder (particle size is 1000 mesh) ), 15 parts of adhesive polyacrylate (molecular weight 15000), 50 parts of deionized water, and after stirring for 2 hours at a speed of 4000 rpm under normal temperature and pressure, low emissivity paint T3 is obtained, which is applied to Shanghai Physics of Chinese Academy of Sciences The IR-2 dual-band emissivity measuring instrument developed by the Institute of Technology has a measured emissivity of 0.56.

[0063] The visible light-near infrared reflectance test results of the polyester / cotton blended fabric coated with the coating prepared in this example are as follows figure 1 As shown by the middle C curve, it can be seen that the reflectance c...

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 infrared low-emissivity earth yellow stealth paint and a preparation method thereof, and belongs to the field of textile material science. Background technique [0002] Infrared light (line) is an electromagnetic wave with a wavelength of 0.7~1000μm. Physically speaking, objects with a surface temperature above absolute zero will radiate to the outside world in the form of infrared rays. Due to the presence of impurities such as water vapor and dust in the atmosphere, most of the infrared wavelengths will be reflected, absorbed, and scattered. But in the following three wavebands: 1~2.5μm, 3~5μm and 8~14μm, the infrared transmittance is relatively high and it is basically transparent, commonly known as the atmospheric window. Among them, the infrared radiation of 3~5μm and 8~14μm is the heat radiation caused by the temperature of the target and the background itself. Military infrared detection is mainly to collect infrared si...
