Abstract
An infrared spectroscopy study of changes in chemical composition as a result of thermal destruction of flame-retardant bulging coatings based on an acrylic organo-soluble binder, as well as on a vinyl water-soluble binder, was carried out. Absorption bands characteristic of flame retardant components and binders included in the coatings under study have been established. The absorption bands undergoing the most significant changes at temperatures from 100 to 500 °C are selected and the optical densities of the selected bands are calculated. Using the ratio of the optical densities of the selected absorption bands, spectral criteria for each temperature were calculated and calibration dependences were constructed, which subsequently allowed them to be used to determine the degree of thermal damage to the studied flame retardant coatings. It is shown that the IR spectroscopy method will allow solving issues related to the study of flame-retardant bulging coatings and their residues formed as a result of temperature exposure in a fire.
