Abstract: The technologies for obtaining and modifying heat-insulating materials using nanosized silica are presented. The effect of a hydrophobizing emulsion upon the addition to the binder of mineral wool boards on their characteristics has been determined. A technology for the production of porous heat-insulating materials based on nanosized aerosils has been developed and their structural and mechanical properties have been studied.

Keywords: pyrogenic silica, hydrophobizing emulsion, mineral wool insulation boards, density, water absorption, thermal conductivity.
