FIELD: fire-extinguishing materials.
SUBSTANCE: invention relates to an area of preparing aerosol forming fire-extinguishing compositions containing potassium or sodium nitrate as oxidant. Method according to invention comprises mixing appropriate components and molding samples. When samples are removed from mold, their surface is moistened with liquid mixture consisting of 20-50% epoxide resin, 2-5% dibutyl phthalate, 5-8% polyethylene-polyamine, and acetone (to 100%). Thereafter, samples are partially dried for 1-2 h at room temperature and then dried for 1-5 h at 60-100°C.
EFFECT: enhanced moisture resistance of compositions.
