Description
Technical field
The present invention relates to a kind of compo extensively can inhaling radar wave, belong to technical field of coatings.
Background technology
Modern radar wave band refers to the range of frequency of radar emission electric wave, and its linear module is hertz (Hz) or cycle per second (C/s).Most of radar is operated in and ultrashortly involves microwave region, its range of frequency is at 30 ~ 300000 megahertzes, respective wavelength is 10 meters to 1 millimeter, comprises very high frequency(VHF) (VHF), ultra-high frequency (UHF), ultra-high frequency (SHF), extremely-high frequency (EHF) 4 wave bands.But the reflection of being obstructed that is transmitted into of any ripple all be unable to do without electromagnetism, if any by this transmitting electromagnetism molecular absorption, generation echo can not reflected, just can reach stealthy, be convenient to military, can available protecting oneself.
Summary of the invention
The object of the present invention is to provide a kind of compo extensively can inhaling radar wave, to improve coating result of use better, provide a kind of coating with better effect.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of compo extensively can inhaling radar wave, be made up of the material of following mass percent: carbon dust 40 ~ 60%, silicon single crystal 20 ~ 40%, silica gel 10 ~ 30%, above-mentioned coating preparation method is, the conventional rotating speed mixing under traditional vacuum state of the carbon dust of above-mentioned mass percent, silicon single crystal and silica gel can be obtained finished product in 0.5 ~ 1 hour, and barrelling is stand-by; During concrete use, first by coating bottoming on required object, then stick carbon fiber, then coat and be coated with flat by carbon fiber surface, above-mentioned thickness is 0.5 ~ 1 centimetre.
Further, silica gel is Kiselgel A.
Further, silicon single crystal is the high-purity fine monocrystalline silica flour of less than 0.13 μm.
In above-mentioned compo, each component function is as follows:
(1) silicon single crystal: be a kind of more active non-metallic element, it is the important component part of crystalline material, its main application be used as semiconductor material and utilize solar energy power generating, mix trace VA race element, form N-type, N-type and P-type semiconductor combine, just can make solar cell, electromagnetic radiation energy can absorb by it changes electric energy into simultaneously; Silicon single crystal is the high-purity fine monocrystalline silica flour of less than 0.13 μm.
(2) graphite carbon dust: high temperature resistant type, the fusing point of graphite is 3850 ± 50 DEG C, and boiling point is 4250 DEG C, even if through the calcination of ultrahigh-temperature electric arc, the loss of weight is very little, and thermal expansivity is also very little.Graphite intensity temperature improves and strengthens, and 2000 DEG C time, graphite intensity doubles.Conduction, thermal conductivity are strong, and the electroconductibility of graphite is higher than general nonmetalliferous ore 100 times.Thermal conductivity exceedes the metallic substance such as steel, iron, lead.Thermal conductivity raises with temperature and reduces, and even at very high temperatures, graphite becomes thermal insulator.
(3) silica gel, another name: silicic acid gel is a kind of high reactivity sorbing material, belong to amorphous substance, its chemical molecular formula is mSiO
2nH
2o; Do not react with any material except highly basic, hydrofluoric acid, water insoluble and any solvent, nonpoisonous and tasteless, stable chemical nature.The silica gel of various model forms different microvoid structures because its manufacture method is different.The chemical composition of silica gel and physical structure, determine it and have other same type of material many and be difficult to replace to obtain feature: absorption property is high, Heat stability is good, stable chemical nature, have higher physical strength etc.Silica gel is divided into according to the size in its aperture: macroporous silica gel, silochrom, Type B silica gel, Kiselgel A etc.Just Kiselgel A is adopted in the present invention's formula.
(4) carbon fiber (carbonfiber is called for short CF), is the tencel material of the high strength of a kind of carbon content more than 95%, high modulus fibre.It to be piled up along fiber axial direction due by organic fibres such as flake graphite crystallites to form, the micro crystal graphite material obtained through carbonization and graphitization processing.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than iron and steel, and has characteristic that is corrosion-resistant, high-modulus.
This beneficial effect of the invention is: the compo of foregoing invention, and result of use is good, and it is 45% that ripple rate is inhaled in exhaustion, can extensive absorbing radar wave, facilitates and uses as required.
