Description
Technical Field
The invention relates to a low-emissivity nano coating and a preparation method and application thereof.
Background
With the development of the infrared detection technology and the guidance technology, the spatial resolution of a thermal infrared imaging instrument working in an infrared band (with the wavelength of 8-14 mu m) reaches 0.1-0.2 mrad, and the temperature resolution reaches 0.1-0.3 ℃. The infrared stealth technology is taken as an important factor for improving the survival ability, the penetration ability and the operational efficiency of the operational unit, thereby causing high importance of all countries, and the importance of the infrared stealth technology in the modern information operations is increased day by day. The infrared stealth technology can be roughly summarized into three aspects of changing infrared radiation wave bands, reducing infrared radiation intensity and adjusting infrared radiation transmission processes. The infrared radiation intensity of the target surface can be reduced by coating the infrared stealth coating on the target surface, and the research on the low-emissivity coating is the key of the preparation research on the infrared stealth coating. Wherein, the wave band of 8-14 μm is one of the important wave bands of infrared thermal imaging.
The infrared stealth paint generally consists of a coating agent and an additive. The coating agent is a high-molecular coating agent with certain infrared transparency; the additive comprises: fillers, wetting dispersants, defoamers, crosslinkers, solvents, diluents, and the like; the filler comprises metal filler and semiconductor filler. Research shows that the coating agent has an influence on the coating emissivity of over 60 percent, and most of common coating agents have high infrared emissivity, so that the requirement of low emissivity of infrared stealth is difficult to meet. Some researchers have synthesized infrared transparent coating agents to reduce the coating emissivity, and the modified ethylene propylene diene monomer is the most typical, but has the disadvantage of low adhesive strength and easy falling off in practical application. The polymer conductive coating agent has the problems of no high temperature resistance, poor aging resistance and the like. Among a plurality of fillers, the metal filler is the most reported low-emissivity filler so far, and has the defects that the metal filler has high reflectivity, is not beneficial to the multi-band compatibility stealth of visible light, radar, laser and the like, and is easy to oxidize in the air, so that the infrared emissivity of the metal filler is greatly improved; meanwhile, after the low-emissivity coating made of the metal filler is coated on a fabric, the fabric feels hard, and the adhesion fastness cannot meet the actual requirement. The combination of the semiconductor filler and the infrared transparent coating agent can effectively overcome the above disadvantages, and thus becomes an important point of research and application. The effective selection of different types, granularities and addition of semiconductor fillers is optimally combined with the infrared transparent coating agent, and the key points for preparing the low-emissivity coating and realizing infrared stealth are realized.
The doped semiconductor filler is one of infrared stealth materials with excellent comprehensive performance. The more studied doped semiconductor materials are ITO (indium tin oxide) and ATO (tin antimony oxide). As the raw materials In and Sn for preparing ITO and ATO belong to rare metals, the manufacturing cost is increased, and the application of ITO and ATO is not facilitated. ZAO (aluminum-doped zinc oxide) is a novel semiconductor stealth material, has lower cost compared with ITO and ATO, and is considered as a doped semiconductor material with wide development prospect; the disadvantage is that the emissivity of the coating prepared from it is high. The Zinc Oxide Co-doped Gallium Aluminum (Gallium and Aluminum Co-doped Zinc Oxide, GAZO) is a semiconductor material with low emissivity, and researches on GAZO at home and abroad are mostly concentrated on GAZO sputtering films, but researches on applying GAZO powder as a filler to infrared stealth materials are not reported yet.
