Determination of flame- retardant efficiency conservation term of thermo-foaming flame- retardant paints

The article defines the endurance period of fire protection efficacy as one of the most important characteristics for quality assessment of fire retardants. Experimental methods for determination of endurance period of fire protection efficacy for fire retardant coatings and endurance period of fire protection efficacy for impregnating compounds as well as endurance of fireproof wood are given. It is shown that modern fire retardant compounds represent complicated systems of non -organic and organic components and because of that the existing ex press methods for determination of endurance period of fire protection efficacy for paint coatings are not suitable for that. Endurance period of fire protection efficacy under natural conditions can be predicted by reproduction under simulated conditions of external factors with certain intensity and duration.
