Description
Technical Field
The invention relates to the technical field of pigments, in particular to an anti-reconnaissance camouflage functional inorganic pigment, an inorganic printing coating containing the anti-reconnaissance camouflage functional inorganic pigment, and a fabric using the coating.
Background
Inorganic oxide pigments are widely used in the national economic fields of coatings, inks, ceramics and the like due to their good temperature and chemical stability. The spectral reflection characteristic is an important parameter for representing the performance of various inorganic pigments and is one of the inherent attributes of the inorganic pigments, and the color tone and the brightness of the pigments are directly determined by the reflection characteristic in the visible light wave band (400 nm-700 nm) of the solar spectrum; the reflection characteristics at the near-infrared end of the spectrum (700nm-2500nm) are closely related to the solar heat absorption/reflection properties of the pigment. Typical white pigments have high reflectance (greater than 60%) in the visible-near infrared band; the color pigments have a low reflectivity (10% -20%) and thus exhibit a significant heat-accumulating effect under solar radiation. The spectral reflection characteristics of the inorganic oxide pigment are closely related to the components, microstructure, morphology, particle size and the like of the inorganic oxide pigment, particularly the local electronic environment of metal ions Mx + in the pigment components, such as coordination structure, M-O bond structure, ion level, optical band gap and the like.
"pigment printing" also called "pigment printing" is more weather resistant because it uses pigment as the coloring body and has better color stability compared with dye coloring, especially inorganic pigment can ensure that the pigment does not change color even if used continuously for years outdoors. In addition, with the development of the camouflage material technology in recent years, the optical camouflage performance of the camouflage functional pigment is greatly superior to that of dyes, the camouflage functional ceramic pigment developed by the research institute of later building engineering can realize the simulation of the spectrum reflection characteristic of natural green plants in the wave band range of 400-1000 nm to the same color and spectrum, the fineness and the tinting strength of the pigment meet the practical requirements, and the weather resistance and the optical camouflage performance of the tent cloth can be greatly improved by applying the pigment to the tent cloth printing.
For example, Chinese patent CN102747615A discloses an inorganic printing paint, a preparation method thereof and a method for printing camouflage tent cloth by using the paint, and the inorganic printing paint is characterized by being prepared from 10-35% by weight of water, 1-3% by weight of propylene glycol, 0.1-0.3% by weight of defoaming agent NOPCO NXZ, 0.5-1.5% by weight of dispersant Corning 5040, 23-43% by weight of anti-reconnaissance functional inorganic pigment, 0.1-0.5% by weight of camouflage net blocking prevention aid NEO-LICILAP/ET, 38-58% by weight of printing resin FS462 and 3-13% by weight of thickener FS 300B.

The technical scheme discloses that the pigment contains a multi-element metal oxide of elements such as chromium, cobalt, zinc, titanium and the like, and forms a reflectivity mutation in a wave band of 680 nm-760 nm, which is closer to the spectral reflection characteristic of green vegetation; the high-reflectivity optical fiber has high reflection characteristic in a near infrared band of 750-1200nm, the reflectivity is close to 60%, however, in the scheme, only three compounds of which the main phase is chromium oxide and the doped phase is cobalt oxide and titanium dioxide are contained, and the high-reflectivity optical fiber is a spinel-structured composite oxide, but the compound has the function of anti-radar wave detection.

Researches find that various fibers/fabrics with heat absorption and heat insulation functions are mainly adopted to realize heat inhibition for a static high-temperature target, and a layer of heat reflection material is added on the surface of the target needing to be concealed to form the thermal infrared concealed camouflage shelter. The method adopted by the embodiment is to coat the fiber fabric with an infrared reflecting material (such as metal aluminum, zinc and the like) to effectively reflect infrared rays emitted by a target. It is worth noting that the thermal infrared stealth technology is used for disguising, reducing and controlling characteristic signals of an infrared band of 8-14 mu m of a target and improving the concealment of individual action, and is a great characteristic of modern high-tech wars. The principle of the heat-proof infrared reconnaissance is to eliminate and reduce the difference of infrared rays between a target and a background so as to fulfill the aim of camouflage, and infrared light stealth requires that the fabric has high reflectivity and low emissivity to infrared light. Thermal infrared camouflage coatings (i.e., metallic aluminum, zinc coatings, etc.) bring the surface temperature of the target as close as possible to the background temperature, thereby reducing the radiation contrast of the target and the background and reducing the probability of the target being detected.
