Abstraction. The results of theoretical and experimental studies to justify the optimal formulation of compositions for thin-layer fire-retardant coatings of steel building structures are presented. More than 30 flame retardant coatings based on liquid-glass binders of the "Firex" series, on organic emulsions of the "Joker" series and epoxy-based "Leader" series have been developed. Studies were performed with due regard for the set of operational requirements for steel building structures, such as resistance to moisture, corrosive environments, as well as to seismic shocks. All compositions are manufactured from domestic raw materials and components. The technological process of compositions production and their application is based on the use of domestic equipment and tools. Therefore the cost of compositions is significantly lower compared to imported analogues. The compositions considered have been successfully operated for a long time at many objects of general civil and special purpose.
Key words: steel building structures, thin-layer fire retardant coatings, organic emulsions, operation conditions. - REFERENCES
