Description

technical field [0001] The invention relates to the technical field of aircraft coatings, in particular to an aircraft radar anti-stealth coating and a preparation method thereof. Background technique [0002] Judging from the current situation of the development of stealth technology at home and abroad, "thin, wide, light, and strong" is the development direction of stealth technology. Therefore, it is an inevitable trend to develop and develop nano-stealth coatings with good broadband compatibility, low cost and multiple functions. First of all, the struggle for military reconnaissance increasingly requires stealth materials with better performance; secondly, the development of nanotechnology provides the technical basis and material reserves for nano-stealth coatings, and these two factors will promote the development of nano-stealth coatings to a higher level . As countries pay more and more attention to stealth technology, research on nano-stealth coatings will become...
