Abstract. This research defines the role of the flame retardants on the cultural heritage objects in the process of the thermal decomposition of wood. In this research we provide the analysis of the influence of flame retardants on the thermal decomposition of wood of monuments of wooden architecture in 1720-1892. Monuments of wooden architecture in Russia are objects of world cultural heritage. According to the Ministry of Culture of the Russian Federation, as of September 1, 2017, there are 7901 objects of wooden architecture monuments on the territory of the Russian Federation, 1182 cases of loss of monuments were recorded. Studies of thermal decomposition of samples of wooden structures of wooden architecture monuments built in 1720-1892 showed different resistance of wood of different service life to thermal decomposition. The purpose of this research is to establish the features of thermal and thermal-oxidative decomposition of wood structures of monuments of wooden architecture of different periods of operation, as well as to study the effect of Senezh fire retardants and a composition consisting of phosphonic acid (amino trimethylene - 30%) and carbon nanotubes 0.1%. The method of this research is an analysis of samples of structures of wooden architecture monuments of various periods and operating conditions. The results show that the highest rate of thermal decomposition (5.7%/min) is observed in wood structures of the monument of wooden architecture. [ABSTRACT FROM AUTHOR] |
