Problems solved by technology

However, the green color of the traditional automotive camouflage paint must meet the camouflage requirements of a typical green background and can only be used for high emissivity, and cannot simultaneously meet the camouflage requirements of optics, infrared, and mid-to-far infrared in 3-color or 4-color camouflage under this background. , especially coatings with a variety of green backgrounds cannot meet the requirements of 3-5μm and 8-14μm under the condition of emissivity of 0.6-0.95, which can meet the high, medium and low emissivity while being compatible with visible light, near infrared and hyperspectral camouflage
[0003] Obviously, traditional car camouflage coatings can no longer meet the needs of future warfare. More and more scientific research institutions have begun to find solutions in other new materials, such as semiconductor materials such as ITO and some conductive polymers to solve the current problems. , and conducted a lot of research, the biggest disadvantage of these materials is the high price
[0004] In the traditional process, aluminum powder is a component often used in the development of camouflage coatings, and sometimes it is even used as the key to solving the problem of low emissivity, but the brightness of aluminum powder itself is very high, and the low brightness camouflage color in the relevant national military standards The brightness is generally low, and it is difficult to be compatible with visible light camouflage and anti-infrared camouflage reconnaissance
