The protective properties of liquid environmentally friendly materials for shielding electric, magnetic and electromagnetic fields of a wide frequency range have been studied. Materials were made on the basis of iron ore concentrate, water-dispersed and geopolymer paints were used as a matrix. Tests of protective properties for electric and magnetic components of the electromagnetic field of industrial frequency have shown that the coefficients of shielding of the electric fiel d at the concentration of the shielding substance 15−60% (by weight) - 1,1−8,6; magnetic field - 1.2−5.3. The shielding coefficients of the material based on water-dispersed paint are lower than the geopolymer, which can be explained by the oxidation of the iron-containing component and the decrease in electrical conductivity. The shielding coefficients of the electromagnetic field with a frequency of 2.45 GHz are 1.2–7.9.Downloads
