Zusammenfassung:FIELD: manufacture of sealing materials on base of liquid thiocol for sealing-up fuel compartments and structural members of flying vehicles; aerospace engineering; automobile manufacture; shipbuilding. ^ SUBSTANCE: proposed method includes mixing the sealing and vulcanizing pastes containing dibutyl phthalate with vulcanization accelerating agent; prior to preparation of vulcanizing paste, carbon nano-modifying agents are additionally introduced into dibutyl phthalate and dispersion thus obtained is treated by ultrasound. Used as carbon nano-modifying agents is fulleroid multi-layer nano-modifying agent Astralene or open carbon nano-tubes in the amount of 0.037-0.069 or 0.014-0.020 parts by mass, respectively per 100 parts by mass of vulcanizing paste. ^ EFFECT: enhanced tensile strength; reduction of relative elongation; enhanced fuel resistance properties and fungus resistance. ^ 3 cl, 1 tbl, 8 ex
