The base core consists of hollow microspheres made of coal ash of a thermal power plant, development and utilization of the hollow microspheres of the thermal power plant are promoted, and the infrared-microwave integrated stealth hollow microspheres composite coating has an important theoretical value, an application value and an environmental protection value and is applied to the field of national defense and electromagnetic radiation protection.
Description
Technical field
The utility model relates to a kind of camouflage coating, especially for the integrated stealthy cenosphere composite coating of infrared-microwave.
Background technology
That microwave absorption at present commonly used mainly contains is little, ultramicro magnetic metal and alloy powder absorbent, ferrite absorbent, conduction high polymer absorbent etc., and absorbent is also developing to efficient, light weight degreeization and compoundization direction.Still there are shortcomings such as frequency band is narrow, efficient is low, density is big in the absorbent that uses both at home and abroad at present and develop, and range of application receives certain limitation.Existing research shows that the compound or preparation multilayer microwave absorbing coating of multiple absorbent is favourable to expansion absorption band, raising assimilation effect.But existing complex technique and multilayer microwave absorbing coating technology are limited to the frequency band expanding space, fail to make a breakthrough from absorbent structure and wave-absorbing mechanism aspect, and still difficulty reaches the effect of microwave absorbing coating " thin, light, wide, strong ".For satisfying the effect of microwave absorbing coating " thin, light, wide, strong ", need the high performance absorbent of research and development.
Contemporary military affairs survey and guidance technology in radar and infrared be two kinds of the most common and topmost technology.The compatible multi-functional stealth material of infrared-radar is carried out the earliest in the development of multi-functional stealth material, and report at most.The compatible multi-functional stealth material of infrared-radar requires at visible light and near-infrared the camouflage effect is arranged, and microwave is had the high low reflection that absorbs, and at the thermal infrared wave band low-launch-rate is arranged.Present applicable thermal infrared stealth material and Radar Stealth Materials all can not reach above-mentioned requirements.
The utility model content
The purpose of the utility model invention is can not realize the incorporate problem of infrared-microwave in order to solve existing stealthy protection composite coating, and provide a kind of infrared-the integrated stealthy cenosphere composite coating of microwave.
The integrated stealthy cenosphere composite coating of a kind of infrared-microwave of the utility model; It comprises cenosphere base nuclear, active layer and metal alloy layer; Described active layer is coated on the outer surface of cenosphere base nuclear, and described metal alloy layer is coated on the outer surface of active layer.
The beneficial effect of the utility model:
The utility model is to be base nuclear with the cenosphere, outer bag active layer and metal alloy layer, and wherein metal alloy layer is made up of the metal of nano particle, and metal alloy layer is that layer coats, and belongs to irregular layer; The present invention is infrared-and the average emitted rate of the infrared band (wavelength 8～14 μ m) of the integrated stealthy cenosphere composite bed of microwave is 0.56～0.80; Absorbing property is to be-7.598dB at the average absorbing property of 8～12GHz.Absorbing property at 8～18GHz is-24dB.
The integrated stealthy cenosphere composite coating of the infrared-microwave of the utility model can effectively alleviate the weight of camouflage coating, has lower infrared emittance and microwave absorbing property preferably, can realize that infrared-microwave is integrated stealthy.The utility model serves as a base nuclear with thermal power plant's coal fly ash hollow micro bead; And make it to be applied to the Defence business and the electromagnetic radiation protection cause of China; Promote the development and use of thermal power plant's coal fly ash hollow micro bead, have great theoretical value, actual application value and the value of environmental protection.
