Description
Technical field
The present invention relates to absorbing material fields, inhale wave plate and its preparation side more specifically to a kind of lightweight broad-band structure
Method.
Background technique
The development of contemporary electronic information technology, the electromagnetic pollution as caused by electromagenetic wave radiation, electromagnetic interference, the problems such as divulging a secret
The extensive attention for causing people has become the one of selection to shielding electromagnetic waves and absorption especially in terms of construction material
A important consideration factor.Wave honeycomb is inhaled with cellular high-strength, Gao Mo, light and to the good absorbability of electromagnetic wave spy
Point, it has also become the hot spot of numerous researchers.
The mechanism of immersion-type Honeycomb Sandwich Microwave Absorbing Materials can be described as: sandwich is entered by wave transparent surface layer
The electromagnetic wave of inside configuration carries out Multiple Scattering by sandwich cavity and absorbs, the electromagnetic energy and thus of decaying to the maximum extent
Obtain wideband assimilation effect.
For cellular sandwich type absorbing material, absorbing property is removed to be had outside the Pass with the specification of honeycomb itself, mainly
Depend on and dipping glue system.Studies have shown that a preferable dipping glue system can make honeycomb core in the lesser situation that increases weight
Under reach preferable wave-absorbing effect.
Summary of the invention
For the above content, the present invention provides a kind of lightweight broad-band structure and inhales wave plate and preparation method thereof, utilizes related system
Standby technique impregnates honeycomb with solvent type antiradar coatings, by carrying out electromagnetic wave to suction wave honeycomb, panel, polyurea coating
With design, while improving its related environmental resistance it being inhaled, wave frequency band is further broadened and absorbing property obtains greatly
Amplitude improves.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of lightweight broad-band structure inhales wave plate, including honeycomb
Core material, microwave absorbing coating, panel and polyurea coating.The cellular unit of honeycomb core material is hexagon, is impregnated on cellular unit wall molten
Dosage form microwave absorbing coating；Suction wave cellular material upper and lower level after dip forming pastes wave transparent panel, spray polyurea coating on panel, most
It is prepared into eventually and inhales wave plate with the excellent lightweight broad-band structure of suction wave, carrying, anticollision, resistance to environment.
Preferably, the material that honeycomb core material uses is adhesive layer between any two cellular unit for aramid paper.
The formula of heretofore described solvent type microwave absorbing coating, it is preferably as follows: its in parts by mass, ingredient are as follows: ethyl alcohol 100
~150 parts, 8~9 parts of carbon black, 1~2 part of graphite, 85~100 parts of barium phenolic aldehyde, 670 5.2~6.4 parts of dispersing agent, coupling agent 0.6
~0.9 part.
The invention also discloses the preparation methods that the lightweight broad-band structure inhales wave plate, comprising the following steps:
1) prepared by honeycomb absorbing material: honeycomb dipping being slowly poured into dipping tank with solvent type antiradar coatings, makes sky
White honeycomb core material is sufficiently impregnated, and after room temperature sunning, is carried out precuring, is finally carried out curing molding；Make in honeycomb core material cell-wall
Dip forming solvent type microwave absorbing coating；
2) panel is bonded: being bonded wave transparent panel with the upper and lower faces of adhesive honeycomb absorbing material after curing molding；
3) spray polyurea coating: in upper layer panel surface spray polyurea coating.
Wherein, step 1) blank cellular material dip time about 5min；
2) panel is bonded.Epoxy panel is chosen as wave transparent panel, by 8810 glue of honeycomb absorbing material after curing molding
Panel is Nian Jie with honeycomb absorbent structure.
3) spray polyurea coating.On upper layer, the polyurea coating of panel surface spraying 0.8-1.5mm thickness, plays matching and inhales wave knot
The electrical property of structure plate and the effect of anticollision.
The beneficial effects of the present invention are: the solvent type antiradar coatings are using ethyl alcohol as solvent；Carbon black and graphite conduct
Wave absorbing agent；Barium phenolic aldehyde is as resin matrix；Cooperate dispersing agent and coupling agent synergistic effect, so that antiradar coatings have absorbing property
Well, absorption band is wide, good compatibility and the features such as light weight, is much better than conventional antiradar coatings.The present invention utilizes solvent
Type antiradar coatings impregnate honeycomb, by mentioning to wave honeycomb, panel, polyurea coating progress electromagnetic wave matched design is inhaled
While its high related environmental resistance it being inhaled, wave frequency band further broadens and absorbing property is greatly improved.
