Stealth coating is a stealth material that is fixedly applied to the structure of the weapon system. According to its functions, it can be divided into radar stealth coating, infrared stealth coating, visible stealth coating, laser stealth coating, sonar stealth coating and multifunctional stealth coating. Stealth coatings are required to have: chemical stability over a wide temperature; better band characteristics; small areal density, light weight; high bond strength, resistance to certain temperatures and different environmental changes. New radar stealth coating When the electromagnetic wave emitted by the radar hits the metal material, it is easy to induce the same-frequency electromagnetic current and establish an electromagnetic field, and radiate energy to the radar twice. The research of radar stealth technology mainly focuses on two aspects of structural design and absorbing materials. In the material stealth design, there are two key issues: one is how to allow the incident wave to enter the inside of the material to the maximum without being reflected by the surface; the second is how to allow the electromagnetic wave entering the inside of the material to be quickly absorbed by the material. Radar stealth coatings are designed to minimize the possibility of being surveyed by radar. New infrared stealth coating The infrared stealth coating is simple in process, convenient in construction, durable and low in cost, and is the most important variety in stealth coatings. It is mainly aimed at the detection of infrared cameras, aiming to reduce the brightness of the aircraft in the infrared band, masking or deforming the shape of the equipment in the thermal imaging camera, reducing the probability of its being discovered and recognized. The key to infrared stealth is that the target can form thermal camouflage by using the difference of radiance in different regions. The key to the development is to find a low emissivity resin adhesive. The rubber butyl rubber, polyethylene and vinyl acetate copolymer having a ring structure have better infrared transparency and can be used as an adhesive for infrared coatings. New visible light stealth coating Visible light stealth coating, also known as video stealth technology, is a stealth technology for people's visual, camera, camera and other observations, the purpose is to reduce the target characteristics of the aircraft itself, less brightness and color between the target and the background The contrast characteristics of degrees and motions achieve control of the target visual signal to reduce the probability of the visible light detection system finding the target. Visible light stealth coatings usually use camouflage methods to make the aircraft stealth, such as camouflage, camouflage, and camouflage. A visible light stealth is a camouflage barrier, which can simulate the electromagnetic wave radiation characteristics of the background, so that the target can be shielded and merged with the background, which is the main means for the fixed target and the moving target to stay, and the camouflage paint is applied by this technology. Important composition. All in all, visible light stealth coatings are widely used, easy to use and economical, and are relatively mature technologies in the development of aircraft stealth coatings. New multi-spectral stealth coating These types of coatings generally refer to visible, infrared and radar-compatible stealth coatings. With the advent of advanced detection equipment such as advanced infrared detectors, meter wave radars, millimeter-wave radars, and laser radars, stealth materials are becoming compatible with meters. Multi-spectral direction of multi-band electromagnetic wave stealth, such as centimeter wave, infrared, laser, etc. In recent years, foreign advanced multi-functional stealth materials have made some progress in the integration of visible light, far infrared, 8mm and 3mm five-band. New laser stealth coating The precision of laser-guided missiles or bombs has reached an astonishing level of accuracy, so that they can be hit when they are discovered, and they will be destroyed when they are hit, seriously threatening the survival of ground weapons. Therefore, on the modern battlefield. Laser stealth of ground weapons is essential. The principle of laser stealth is mainly based on the ranging equation of the laser range finder. To achieve laser stealth, the distance measurement capability of the laser range finder is shortened and the maximum range is shortened. The reflectivity of the target to the laser must be reduced. At present, the detection frequency of commonly used laser detectors is mainly concentrated in two frequency bands of 1.06 μm and 10.6 μm. In this frequency band, laser stealth coatings have high molar absorption rate, and have excellent comprehensive properties such as chemical stability, thermal stability and mechanical properties, so the application range is wide. From the current situation of stealth technology development at home and abroad, "thin, wide, light and strong" is the development direction of stealth technology. Therefore, it is an inevitable trend to develop and develop nano-stealth coatings with good broadband compatibility, low cost and multi-function. First of all, the military reconnaissance struggle increasingly requires better stealth materials. Secondly, the development of nanotechnology provides a technical basis and material reserve for nano stealth coatings. These two factors will promote the development of nano stealth coatings to a higher level. . With the increasing emphasis on stealth technology in various countries, the research on nano stealth coatings will be deeper, and the application of nano stealth coatings in various military equipment will become possible.
