Abstract

The purpose of this research is to study the optical properties of the binders-lacquers based on organosilicon lacquers and epoxy resins modified by nanopowders ZrO2, Al2O3, CeO2, SiO2, TiO2 with concentration from 0.5 to 5 wt%, before and after proton irradiation Ep = 100 keV, Ф = 5 × 1015 cm−2. Analysis of the diffuse reflection spectra and calculation of the solar absorptance were performed. It was found that radiation stability of organosilicon lacquer is higher than of epoxy resins for both modified by nanopowders and not modified. It was established that the introduction of small concentrations (1–2 wt%) of nanopowders to binders based on organosilicon lacquer promotes decrease of their solar absorptance. Radiation stability of organosilicon lacquer (ΔaS = 0.06) modified by SiO2 nanopowder (ΔaS = 0.012 for 1 wt%) is higher compared with other types of nanopowders ZrO2, Al2O3, CeO2, TiO2 (ΔaS = 0.024, 0.026, 0.034, 0.04 accordingly for 1 wt%).
