Description
Technical field
The present invention relates to invisible coating more particularly to a kind of preparation methods of aviation antiradar coating.
Background technique
Radar wave camouflage coating, the radiant energy absorbance of incident radar, scattering can be made radar wave not reflect largely and reach by it
To the purpose of concealed target.Mainly it is made of base-material and filler.Common base-material has natural and synthetic rubber, neoprene, butyl rubber
Glue etc.), pitch, alkyd, polyvinyl chloride, polyurethane resin etc., mainly play adhesive effect.Filler be absorbing radar wave it is main at
Point, it is made of the ferrimagnet of special MgO, FeO, ZnO etc., there is the prismatic crystallization of energy continuous absorption incidence wave, and had
Certain porosity, so that internal layer absorbs and is caused by the effect of interfering between incidence wave and back wave and generates dissipating for wave
It penetrates, the radar wave reflected back is made to be no more than the 10%~20% of incidence wave.
Currently, due to radar invisible coating easy to use and flexible, adjustable, absorbent properties are good the advantages that and by the world
Radar invisible coating is all employed in the attention of many countries, the stealthy fortification in part and almost all of Stealth weapons system.
The development of radar invisible painting section is so that Stealth weapons system has obtained significant progress, and in the local war of last decade sufficiently
The effective penetration ability and attack function of armament equipment are played, most important application is all kinds of stealthy scoutings of production
Machine, fighter plane, cruise missile etc..It is Russian such as the stealthy fighter plane of the F-22 in the U.S., AGM-129 strategic cruise missiles
The stealthy fighter plane of T-50, the J-20 invisbile plane etc. that China develops.In addition, various countries are also successfully by coating-type absorbing materials
Applied to naval vessel, such as " extra large ghost " battleship of " Xin A Li gram " grade Zeus's shield destroyer in the U.S., Britain.In addition, stealthy
Coating is also applied to tank, such as T-80 main battle tank, MII3 armoured carrier and stealthy automobile, stealth missile transmitting
Vehicle etc..Also plan for radar invisible coating to be applied on stealthy hangar, stealthy tent and the stealthy fighting uniform of soldier in various countries.
Nano material particle is since partial size is minimum, large specific surface area, and the atomic ratio in surface increases, and enhances work
Property, under electromagnetic field effect, atom, electron motion aggravation promote to magnetize, so that electromagnetic energy is the energy of other forms, increase
Add the absorption to electromagnetic wave.Nanoparticle coercivity with higher simultaneously, can cause big magnetic hystersis loss.By nano material
Coating is made as absorbent, it is easy to accomplish high-selenium corn, coating are thin, light-weight, absorption band is wide, infrared microwave absorbs compatibility etc.
It is required that being a kind of very promising high-performance, multi-functional antiradar coatings.The U.S. has developed a kind of " super ink powder " and inhales wave painting
Material, to the absorptivity of radar wave up to 99%.France succeeds in developing a kind of wide spectrum absorption coating, and the coating is by binder
With nanoscale micro mist packing material constitute, have good magnetic conductivity, in 50MHz-50GHz frequency range absorbent properties compared with
It is good.Someone is successfully prepared FeB Ultrafine amorphous alloy particle using chemical method, and this nano particle has biggish magnetic loss
Consumption, is a kind of absorbing material for having application potential.
