FIELD: chemistry.
SUBSTANCE: invention relates to fireproof materials which can be used, for example, in construction, aircraft and space engineering. The fire-resistant composite material contains a perforated mineral fibre material as a base and filler, which contains at least one rubber or polymer, having fire-resistance in the temperature range of 200 to 700°C, or liquid glass, a curing agent and a stabiliser. The material is obtained by perforating mineral fibre material to obtain an area of the perforated surface in the horizontal section of the workpiece of up to 75%. Separately prepared liquid filler is deposited on the perforated surface to fill voids and the volume of perforations at room temperature until density of the composite material reaches 0.25-1.0 g/cm3 and held for 15-28 hours until complete hardening thereof.
EFFECT: invention widens the range of fireproof materials, improved fire-resistance and easy production.
