FIELD: fire-resistant materials. n SUBSTANCE: porous substrate, in particular polymer substrate, is impregnated with fire-resistant agent, namely organophosphorus compound having hydrophilic or hydrophobic nature to be compatible with surface of porous carrier. Impregnation is effected according to dry impregnation technique. n EFFECT: considerably improved fire resistance of materials without harmful effect on properties of material at temperatures above 200°C. n 30 cl, 2 tbl, 4 ex |
