FIELD: building industry. SUBSTANCE: claimed composition for fireproof material comprises (wt parts): 100 butadiene-nitrile rubber; 50-150 oxidized graphite with expansion degree of 50-400 and, optionally, organic solvent. Rubber is mixed with oxidized graphite in organic solvent. Mixture si applied onto fabric substrate and dried at 80-110 C. Properties of material: density is 880-920 kg/cubic m; Shore hardness is 22-25; expansion degree at 300 C is 6- 10 times; fire resistance limit is 45-60. EFFECT: improved properties of the composition. 4 cl
