Abstract
The invention relates to an oily coating, in particular to an oily antiradar coating and a preparation method thereof. The oily antiradar coating consists of the following components in percentage by weight: 35 to 50 percent of solvent, 0.2 to 1 percent of dispersing agent, 10 to 20 percent of resin for coatings, 10 to 20 percent of titanium white, 0 to 20 percent of filler, 0.5 to 2 percent of anti-settling agent, 0 to 2 percent of matte powder, 1 to 2 percent of plasticizer and 0.1 to 5 percent of titanium carbide-based micropipe. After the antiradar coating prepared by the method is subjected to electromagnetic wave absorbing experiments, the effective bandwidth of the antiradar coating for electromagnetic wave absorption exceeds 17GHz; the maximal absorption peak reaches -25dB and the other peaks all exceed -10GHz in the frequency range of 0.2 to 18GHz; the antiradar coating has obvious electromagnetic wave absorption effect and can be used as a good antiradar coating; and the antiradar coating can be used on an outer wall of a building, and the outer wall is made into an absorption wall to prevent indoor and outdoor electromagnetic radiation clutter from transmitting so as to protect indoor human bodies and instruments.
Description
Technical field
The present invention relates to a kind of oiliness rustproof lacquer, be meant a kind of oily antiradar coating and preparation method thereof especially.
Background technology
Antiradar coatings is one of military invisible coating, and the fight that its use makes over the horizon attack, not meet becomes a reality, and makes the modern combat call by pattern to change, and has huge military benefit thus.In addition, application on the product for civilian use is also very extensive, electromagnetic radiation protection as the broadcast television transmitting station, the electromagnetic interference of microwave unreflected chamber abatement apparatus and communication and navigationsystem, security information is maintained secrecy, and the electromagnetic protection of industrial science and medical facilities is coated antiradar coatings to the outside surface of some emphasis military engineerings and secret engineering, guarantee the security of these buildingss on the one hand, in addition irradiation of electromagnetic waves has been played shielding effect.
In antiradar coatings, mainly be that hertzian wave wave absorbing agent in the coating plays the ripple effect of inhaling, wave absorbing agent of the prior art mainly comprises ferrite wave-absorbing material, carbon fiber structural wave-absorbing material, nano wave-absorbing material, chirality absorbing material, polycrystalline iron fiber absorbing material and conduction high polymer absorbing material etc., but also there are many shortcomings such as frequency band is narrow, efficient is low, density is big in these absorbing materials, its range of application is subjected to certain limitation, and is not good by the absorbing property of its antiradar coatings that makes.
Summary of the invention
Main purpose of the present invention is to overcome the not good shortcoming of absorbing property of antiradar coatings in the prior art, provides a kind of titanium carbide base microtubule that adopts as oily antiradar coating of absorbing material and preparation method thereof, can improve the absorbing property of antiradar coatings greatly.
The present invention adopts following technical scheme:
A kind of oily antiradar coating, form by following components in weight percentage:
Solvent 35-50%;
Dispersion agent 0.2-1%;
Coating resin 10-20%;
Titanium dioxide 0-20%;
Filler 0-20%;
Anti-settling agent 0.5-2%;
Mute light powder 0-2%;
Softening agent 1-2%;
Titanium carbide base microtubule 0.1-5%.
In the above-mentioned prescription, dispersion agent, coating resin, titanium dioxide, anti-settling agent, mute light powder and softening agent etc. are composition commonly used in the coating, on market, all can buy, can adopt BYK108,904S type dispersion agent etc. as dispersion agent, solvent can adopt trimethylbenzene, dimethylbenzene and toluene, and filler can be selected fine particle calcium carbonate, coarse whiting or kaolin for use.
The preparation method of described titanium carbide base microtubule comprises the steps: with TiCl
4Being unstripped gas, is raw fibre with carbon spiral microtubule fiber, with H
2Being carrier gas, is shielding gas with the high-purity Ar, is technology depositing Ti C on carbon spiral microtubule fiber with the chemical vapour deposition, makes C/TiC microtubule or TiC microtubule; Temperature of reaction is 800-1300 ℃, H
2Flow is 50-150ml/min, Ar flow 50-150ml/min, TiCl
4Flow is 5-15ml/min, and the reaction times is 5-150mins.
The preparation method of aforementioned a kind of oily antiradar coating, comprise the steps: by weight percentage, the solvent that adds 35-50% earlier, then the dispersion agent that adds 0.2-1% again mixes, the coating resin middling speed that then adds 10-20% is disperseed, throw the titanium dioxide of 0-20%, the filler of 0-20%, the anti-settling agent of 0.5-2%, the mute light powder of 0-2% again and carry out high speed dispersion, the softening agent that adds 1-2%, then low speed disperses, the titanium carbide base microtubule that adds 0.1-5%, filter then, paint is filtered, be in harmonious proportion froth breaking and pack finished product.
The antiradar coatings that the present invention is made carries out the absorption of electromagnetic wave test as can be known, the absorption of electromagnetic wave effective bandwidth of antiradar coatings surpasses 17GHz, in the 0.2-18GHz band limits, removing maximum absorption band reaches-25dB, other is all above-10GHz, tangible absorption of electromagnetic wave effect is arranged, can be used as good antiradar coatings; Outside the building use on the body of wall, make the absorption wall, prevent the clutter radiation transmission of indoor and outdoor, to protect indoor human body and plant and instrument.
