FIELD: porous materials.
SUBSTANCE: invention relates to non-hygroscopic porous material composed of atomized porous material in combination with impregnation composition, particularly fluorine-containing surfactant Epilam in amount found from equation I: (ρpe - ρp)/ρp·100% ˜ N·S·δ·ρe·100%, where S is specific surface area of porous material, including pores, m2/kg; δ thickness of Epilam film after drying and heat treatment, m; ρ-e density of Epilam, kg/m3; ρp density of porous material (powder) before epylamation, kg/m3; and N number of impregnations with Epilam. Invention also relates to a method of preparing non-hygroscopic porous material.
EFFECT: enabled imparting non-hygroscopicity to porous materials and increased application temperature thereof.
