Inhale ripple bionic composite material simulating plant outward appearance, spectral reflectance and absorbing radar wave characteristic so as to reach have concurrently infrared, spectrum into
As the purpose of camouflage, forest land background visual camouflage and radar invisible.
Background technology
With the development of modern science and technology, influence of the electromagenetic wave radiation to environment increasingly increases.Airport, machine flight because
Electromagnetic Interference cannot take off and overdue；The normal work of various electronic instrument for diagnosing and curing diseases devices can be often disturbed in hospital, mobile phone.Cause
This, administers electromagnetic pollution, finds a kind of material that can be kept out and weaken electromagenetic wave radiation --- absorbing material, it has also become material supply section
The big problem learned.So-called absorbing material, refers to the class material that can absorb the electromagnetic wave energy for projecting its surface.Should in engineering
Use, in addition to requiring absorbing material and there is absorptivity high to electromagnetic wave in broad frequency band, also require that it has light weight, resistance to
The performance such as temperature, moisture-proof, anticorrosive.
Referring to Chinese publication CN102087081A（Publication date is on June 8th, 2011）, specifically disclosing one kind has
The stealthy pedaline of wave energy, including careless silk, careless base fabric and gum layer are inhaled, the careless silk is fixed on the careless base fabric, described
Gum layer is coated on the back side of the careless base fabric, and absorbing material is present in the careless silk, careless base fabric or gum layer, can absorb
Electromagenetic wave radiation, can be used in military affairs or wartime anti-radar detection, play military airfield, military limp base, shell storing place,
The stealthy effect in land for military use on a large scale such as underground civil defense engineering.But, above-mentioned pedaline only has absorbing radar wave and reaches thunder
Up to the absorbing material of stealthy purpose, without the material and processing method that have radar, visible ray and infrared stealth performance concurrently, with very big
Limitation.
The content of the invention
For the limitation in existing field, the present invention devises a kind of radar, visible ray and infrared stealth performance of having concurrently
Inhale ripple bionic composite material and preparation method thereof.
To achieve the above object, the present invention uses following technical proposals:
One kind inhales ripple bionic composite material, it is characterised in that inhale ripple bionic composite material by organic biomimetic material and absorbing material
Composition, biomimetic material is planted on absorbing material with careless pencil, and machine biomimetic material is made up of the component of following weight portion：Polyethylene
Alcohol-soluble and water-soluble macromolecule is 1-8 parts；Metal chloride 1-7 parts；Coloring agent 2-6 parts；Crosslinking agent is 2-9 parts；Catalyst is 5-6
Part.
Further, the metal chloride refers to the stronger inorganic salts of hygroscopicity.
Further, the inorganic salts are lithium chloride or calcium chloride.
Further, the crosslinking agent is L MALIC ACID or edible apple vinegar.
Further, the catalyst is acetic acid.
Further, the coloring agent is that chrome oxide green or careless silk are yellow.
A kind of processing method for inhaling ripple bionic composite material, comprises the following steps：
（1）Each component raw material is weighed by weight, by 1-8 parts of polyvinyl alcohol water soluble polymer addition 250mL deionized water
Dissolving, is made poly-vinyl alcohol solution；
（2）1-7 parts of metal chloride, 2-9 parts of crosslinking agent, 5-6 parts of catalyst, 2-6 parts of coloring agent are dissolved in above-mentioned polyvinyl alcohol
In solution, under conditions of being 60-90 DEG C in temperature, by cross-linking reaction 5-6 hours, casting solution is made；
（3）By step（2）In casting solution take out, be placed in baking oven be heated to 80-100 DEG C, 1-1.5h promote polyvinyl alcohol to hand over
Connection will be laid on customization plate after vacuumizing and defoaming again；
（4）Customization plate is placed in climatic chamber and is heated, 40 DEG C of temperature, humidity 45%, heat time 16h obtain sheet organic
Biomimetic material；
（5）By above-mentioned steps（4）The obtained organic biomimetic material of sheet is cut into thread organic biomimetic material using chopping equipment；
（6）Thread organic biomimetic material is bundled into careless beam with 5-10 roots；
（7）Absorbing material is fixed in automatically dropping glue equipment using frock, after careless beam is planted on absorbing material；
（8）Absorbing material and biomimetic material are combined using automatically dropping glue equipment, obtain inhaling ripple bionic composite material.
Further, the step（5）In thread organic biomimetic material width be 1mm.
Further, the step（3）In, casting solution vacuumizing and defoaming is specifically included：By casting solution be placed in bottle,suction or
After being vacuumized in vacuum drying oven, sealing and standing at room temperature is placed in, the time is 18-24h.
The present invention has the following advantages that compared with prior art：
The effect of the crosslinking agent and catalyst that are added in biomimetic material is that both promote polyvinyl alcohol to crosslink reaction jointly.Oxygen
It is bottle green pigment to change chrome green, it is ensured that organic biomimetic material has similar color and spectral reflection characteristic to plant leaf blade.
Metal chloride is that with hygroscopic, in organic biomimetic material adding metal chloride can ensure that composite can be inhaled
It is wet, can adapt to adverse circumstances.Casting solution is to prevent the water loss in casting solution by sealing and standing process.All materials
There is spectral reflectance performance after material fusion, infrared and neighbouring infrared spectrum can be reflected.
Suction ripple bionic composite material prepared by the present invention is carried out into chemical characterization, from Fig. 3-4 as can be seen that prepared by the present invention
Suction ripple bionic composite material compared with RAC16 type absorbing materials, absorbing radar wave characteristic is substantially suitable, illustrates the suction ripple material
After material is compound with biomimetic material, biomimetic material does not have influence substantially on the absorption Radar Objective Characteristics of absorbing material, so as to reach radar
Stealthy effect.Fig. 5-6 is the degree of closeness contrast of biomimetic material and plant, as can be seen from the figure biomimetic material of the invention
It is similar with common plant blade, can simulating plant outward appearance, meanwhile, the biomimetic material has spectral reflection characteristic, reach it is infrared,
Light spectrum image-forming camouflage, forest land background visual camouflage.
Organic biomimetic material in the present invention, can simultaneously realize that the transpiration and spectral reflectance of simulating plant are special
Property.Absorbing material has the characteristic for absorbing radar.Organic biomimetic material and absorbing material are combined into composite, so that this is compound
Material ensure that suction ripple bionic composite material simulating plant outward appearance, spectral reflectance and absorbing radar wave characteristic have concurrently so as to reach
The effect of infrared, light spectrum image-forming camouflage, forest land background visual camouflage and radar invisible.
