Standby brown low infrared emissivity material is particularly useful as infrared camouflage (stealthy) coating.
Background technology
Along with various investigative techniques such as the high speed development of national defence high and new technology, infrared detection, laser emission, radar detections
From discovery so far, obtain the pro-gaze of countries in the world and use.International situation is continually changing, and war situation is more nervous, information
Change war progressively to highlight, precision guided weapon then becomes the emphasis of countries in the world military technology development.Infrared acquisition guidance is military
Device relies on its many advantage, including high accuracy, high sensitivity, high frame frequency, high-resolution, strong interference immunity, and have concurrently can
Automatic identification target, can work double tides the features such as, seeker and ammunition are had been widely used at present.In addition, infrared imaging is visited
Survey technology has distinctive advantage that is disguised, scouting the aspects such as precision, portability, reconnaissance range and anti-interference by it,
Occupy space of prominence in various countries' military surveillance technology, be rapidly developed and be widely used in military affairs.Society
Development accelerates the paces of scientific and technological progress, and the development of modern military technology is particularly swift and violent, various new military surveillance technologies and guidance
The development of technology is maked rapid progress, and is emerged in an endless stream and input application rapidly, and the existence for making combatant and military target is subject to serious
Threaten.In recent years countries in the world adopt infrared detection technique, its severity to reach this stage in local war：If mesh
Mark thing is found that moment will be hit and be destroyed by infrared detection.If our the stealthy means in operation are poor, target will
It is exposed, causes military combat personnel, military target, military weaponry etc. seriously to be threatened.Detect in infrared radar etc.
System is woven on the modern battlefield of dragnet, it is necessary to is effectively hidden oneself, could be made the most of the advantage in operation, ability
Obtain the hope of existence.Various military targets, especially moving target, such as guided missile, aircraft, aircraft carrier, warship, they
Power source power it is big, ferocious infra-red radiation is easily produced during motion；The target of some high-speed motions, in motion process
In, its shell and air frictional heat are also the source of infrared radiation.Infrared acquisition principle is complicated, mainly uses moving target itself
The infra-red radiation of generation is the task such as completing to track, recognize, guide and attack.For near-infrared, the key of target exposure
It is luminance difference of the target itself and background between, and mid-infrared, far main exposure symptoms are then temperature contrasts.
Infrared stealth technology is the emerging technology risen with infrared detection technique.By the structure for improving material
Design and using Infrared Physics principle so that infrared energy is decayed or absorbed, reduce the target property visited.It is infrared hidden
Body technology reduces the infrared intensity and characteristic of target using measures such as low-launch-rate coating, infrared shielding, heat suppression,
Realize the low detectivity of military target.By reducing infrared intensity, changing infra red radiation band, adjust infra-red radiation
Realizing infrared stealth technology, the research of low infrared emissivity coating is research thermal stealth coating to three aspects of transmitting procedure
Crucial and difficult point.
In prior art, Britain《Jian Shi defence》Reported on 2 23rd, 2009：Internet companies develop and develop
Infrared stealth coating technology, the electromagnetic wave transparent material for spraying 50 μ m-thicks just can be with limited target to thermal-radiating absorption and transmitting.
G.Tricot is studied the thing phase change in aluminum phosphate solution temperature-rise period with method associated with XRD and nuclear-magnetism, to only
Supplemented using the XRD analysis message to be provided.A kind of dielectric constant of the Nelson electric corporation research and development of Britain
Between 4.5-7, dielectric loss angle tangent value be less than 0.0003, mainly with phosphate as this kind of material the nuclei of crystallization,
Frequency obtained by its experiment, is mainly used in guided missile and other aircrafts with height both mechanically and thermally between 103Hz and 1010Hz
Glass ceramics antenna house.It can be seen that, phosphate material is very wide in the application that national defense and military fields are obtained, if its emissivity can be reduced
Extremely important impact will be produced for national defence stealth material.
