   <abstract xml:lang="ru">
    <p>Представлены результаты исследования влияния климатических факторов (температуры, влажности) на характеристики термической деструкции и состав газообразных продуктов разложения огнезащитного вспучивающего покрытия на основе акрилового полимера. Методом синхронного термического анализа, совмещенного с инфракрасной спектроскопией газообразных продуктов разложения, установлено, что климатическое старение приводит к смещению начала активного выделения газов в сторону более низких температур. Показано, что в интервале температур около 350–450 °С у состаренного покрытия, помимо аммиака, оксида и диоксида углерода, которые выделяются и в исходном покрытии, присутствуют соединения, содержащие значительное количество ароматических и карбонильных групп, что свидетельствует об изменении химического состава и механизма разложения покрытия. В интервале 550–650 °С, как для исходного, так и для состаренного покрытия, наблюдается выделение в основном оксида и диоксида углерода, связанное с выгоранием пенококса. Полученные результаты позволяют рекомендовать метод синхронного термического анализа, совмещенного с инфракрасной спектроскопией газообразных продуктов разложения, для оценки огнезащитной эффективности покрытий и прогнозирования ее снижения в условиях эксплуатации, в том числе в рамках производства судебных пожарно-технических экспертиз.</p>

    <p>The results of a study of the influence of climatic factors (temperature, humidity) on the characteristics of thermal degradation and the composition of gaseous decomposition products of intumescent fire retardant coating based on an acrylic polymer are presented. By the method of synchronous thermal analysis combined with infrared spectroscopy of gaseous decomposition products, it was found that climatic aging leads to a shift in the onset of active gas release towards lower temperatures. It is shown that in the temperature range of about 350–450 °S with the aged coating, in addition to ammonia, carbon monoxide and carbon dioxide, which are released in the original coating, there are compounds containing a significant number of aromatic and carbonyl groups, which indicates a change in the chemical composition and mechanism of decomposition of the coating. In the range of 550–650 °C, for both the initial and aged coatings, the release of mainly carbon monoxide and carbon dioxide is observed, associated with the burnout of foam coke. The results obtained make it possible to recommend the method of synchronous thermal analysis combined with infrared spectroscopy of gaseous decomposition products to assess the flame-retardant effectiveness of coatings and predict its reduction under operating conditions, including in the framework of forensic fire-technical examinations.</p>
