DEFINITION OF EFFICIENCY OF POLYMETHYLPHENYLSІLOXANE-BASED FIRE PROTECTIVE COATINGS FOR STEEL BUILDING STRUCTURES

Abstract

The article deals with the current problem of determining the fire resistance of protected steel elements of building structures. Based on the analysis of literary sources, the main methods for increasing the fire resistance of steel structures are considered, as well as the use of fire retardant coatings based on polymetallophenylsiloxane. Analytical studies were conducted to determine the time of fire protection of the coating, compared to unprotected structures. The results show that the limit of fire resistance of protected steel constructions is increased 2-4 times, depending on the thickness of the application.
