Атмосферостойкий огнезащитно-огнетушащий состав для предотвращения и тушения пожаров в природном комплексе

Economical wildfire protective nitrogen-phosphorus containing chemical agents on the basis of natural raw materials (dolomite and tripoli) were synthesized. The main factors influencing the synthesized products’ flame retardant properties after the exposure to atmospheric precipitations were investigated. The dependence of the weather resistance of flame-retardant fire-extinguishing suspensions on mineral raw materials nature, on the particle size and the content of its finely dispersed components has been established. It has been shown, that after water treatments of fireproof wood samples, the maximal weatherproof properties were inherent to a suspension based on dolomite, especially after its modification with a water-soluble polymer. Modifying agents have been selected permitting to regulate the sizes of the resulting product grains providing them to be comparable with the pore sizes of such combustible materials as wood and peat.
