METHOD OF MAKING RADAR ABSORBENT MATERIAL AND RADAR ABSORBENT MATERIAL MADE USING SAID METHOD

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to radio engineering, particularly to electromagnetic wave absorbers, including in the microwave range and can be used for ensuring electromagnetic compatibility of radio-electronic equipment, biological protection from effects of radio emissions generated by different scientific and household devices, reducing radar visibility of different objects and is aimed at reducing coefficient of reflection of electromagnetic waves and widening the frequency range of the radar absorbent material, as well as simplifying the method of making said material. When making said material, an oxide hexagonal ferrimagnetic material with a W-shape is mechanically treated in a mechanoactivator for 30-300 seconds with power density factor of 20-40 g and mixing it with epoxy resin in the following ratio, wt %: oxide hexagonal ferromagnetic material with W-shape - 70-91, epoxy resin - 9-30.;EFFECT: use of chemical methods and expensive reagents is completely avoided, the material obtained using the said method has lower coefficient of reflection and a wide frequency range and can be used for making efficient radar absorbent coatings.;2 cl, 2 tbl
