Description

A kind of metal surface coating antiradar coatings and preparation method thereof
Technical field
The present invention relates to inorganic functional material technical field, and in particular to a kind of metal surface coating antiradar coatings and its Preparation method.
Background technology
As the development of science and technology, impact of the electromagenetic wave radiation to environment increasingly increase, produced for suction ripple therefrom The demand of material and shielding material is also increasingly prosperous.On airport, airplane flight is overdue because Electromagnetic Interference cannot be taken off;In doctor Institute, mobile phone can often disturb the normal work of various electronic instrument for diagnosing and curing diseases devices.In future high-tech, three-dimensional war, weapon Equipment is faced with the severe challenge detected with anti-detection at any time.Absorbing material is the key technology in stealth technology, will inhale ripple material Material introduces the research of stealth technology and is paid much attention to by countries in the world, meanwhile, in for fighter plane, guided missile, army in military affairs The stealthy needs of the military equipments such as warship, the demand to being capable of absorbing radar wave material are also increasingly urgent, therefore, no matter for military Or commercial market, absorbing material demand in actual applications all compares urgently.Oneself there are some researches show, applies on armament systems surface Covering absorbing material can effectively reduce electromagnetic wave signal, reach stealth effect, and the Lijima in Japan NEC laboratories in 1991 sends out CNT is showed, there is potential using value in electromagnetic shielding and absorbing material field, but use merely CNT As wave absorbing agent, ideal dielectric loss can be reached, but the magnetic loss very little to electromagnetic wave, while CNT is close It is aqueous poor, easily reunite when absorbing material is prepared, and the easy firing loss under the conditions of 500 DEG C of high temperature airs, and in aircraft The metal parts of the high temperature positions such as jet pipe, its operating temperature often, more than 700 DEG C, easily lose suction using CNT merely Ripple performance.Patent (CN104479626B) disclose a kind of graphite multi-walled carbon nano-tube/Nanocomposites wave absorbing agent and its Preparation method, with good absorbing property, but the air in high temperature and high speed washes away lower coating and easily peels off, and has a strong impact on material Absorbing property.
The content of the invention
The purpose of the present invention is for this problem of the prior art, there is provided a kind of metal surface coating antiradar coatings And preparation method thereof.CNT and resistant to elevated temperatures recessed native powder are combined by the method, prepare absorbing property it is excellent and have There is preferable durothermic wave absorbing agent, then the wave absorbing agent is filled in antiradar coatings together with other components so as to very Good performance of absorbing electromagnetic wave.
