Abstrakt: Recently, coatings that can form a thermal insulation layer on the surface of the building structure have become common, as they significantly reduces the processes of heat transfer to the material. Modern methods of fire protection of building structures are based on the use of swellable coatings, which are complex systems of organic and inorganic components. To determine the effectiveness of fire protection in the developed coatings, studies were conducted on the flammability of thermally modified wood in terms of weight loss and increase in flue gas temperature, and found that when applying the degree of damage to samples by weight does not exceed 5.6% and flue gas temperature does not exceed 76 °C. The results of determining the efficiency of the coating for the system showed that under the influence of high temperature flame combustion of the material and loss of the coating weight decreases due to the formation of high temperature compounds, while the time limit temperature increases. In addition, under the action of a high-temperature flame of a fire furnace, it was shown that the intumescent coating can withstand high temperatures, effectively prevents the penetration of heat into the material due to the formation of a foam layer of coke, which affects the rate and depth of temperature absorption.
