The role and development of stealth coatings

Author:admin   AddTime:2021-09-28

The implementation of camouflage on ground targets is one of the earliest camouflage techniques used. The camouflage paint is used to coat the outer surface of the target into patterns of various sizes and stripes, which can not only prevent visible light detection but also prevent ultraviolet light and near-infrared radar detection. This is the most basic Camouflage measures. Its purpose is to change the contour of the target, make it blend with the background, reduce the optical contrast between the military target and the terrain background, so as to reduce the probability of being discovered.

The business department will discuss with you the research and development of stealth materials.
Camouflage paint has been applied to the tank since its appearance. The pattern is mainly composed of multiple brown, green, and black spots to form the camouflage camouflage of the tank, which reduces the visual characteristics of the vehicle. The experimental results prove that the probability that the c√ tank will appear on the front of the 1000m tank without camouflage is 75%, and the probability of camouflage is 33%. The color, shape and brightness of the paint vary with the terrain, seasons and environmental climatic conditions, so that the color of the tank is consistent with the surrounding environment.

There are three types of camouflage camouflage: ①Protection camouflage suitable for targets on monochrome backgrounds such as grasslands, deserts, and snow; ②Deformation camouflage suitable for moving targets on a mottled background; ③Imitation camouflage suitable for fixed targets. The most representative camouflage paint in contemporary times is the polyurethane camouflage paint that is resistant to penetration by chemical agents in the United States. This kind of paint is easy to clean when it is contaminated by chemical toxicants, especially after switching to three-color camouflage and large spots, it has a better camouflage effect at long and short distances. During the Gulf War, the U.S. military used the new



Successfully developed a new grade of camouflage paint that is resistant to chemical agents, namely standard yellow-brown Tan686, which is painted on the top of the tank, and its infrared reflectance is 45%. When the U.S. military discovered that the deserts of the Arabian Peninsula were brighter than the deserts of other places, they quickly developed the Tan686A, which increased its infrared reflectivity to 70%, and the internal temperature of vehicles or shelters coated with this paint dropped by 8.4°C. .

A multi-purpose camouflage camouflage has been developed abroad. It is made of plastic solution and added 5%-25% (mass fraction) of metal powder to make a shell and phenolic resin plus 10%-15% (mass fraction) of graphite or Composed of conductive fibers made of smoky black, tank vehicles using this camouflage coating can prevent visible light, infrared and radio frequency detection.

The coated multi-band stealth material in Germany is a coating that can work in visible light, thermal infrared, microwave, and millimeter waves. It can make the target feature as close to the background as possible to reduce the detectability of the target. The color and brightness of the zone are suitable, and the gloss is small. In the thermal infrared zone, the radiation temperature of the target can be adapted to the background radiation temperature, and the radiation can be absorbed in the widest possible microwave and millimeter wave bands.
