The goal of the investigation: improvement of intumescent system formulations to enhance their fire-protective and environmental characterisitics by the addition of nanoclays. Research methods: IR spectroscopy (for identification of chemical compounds tested), flame tube experiments and thermogravimetry measurements (studies on fire protective efficiency of antipyrens). Comparison studies of the effects of kaolin clay, nanoclays and modified nanoclays on the formation of coke layer in the intumescent composition ammonium polyphosphate / pentaerythritol / melamin / polymer in the temperature range 200 to 600 оС. Fire-protective intumescent system with cetyltrimethylammonium-montmorillonite was found to be the most efficient. Nanocomposites derived by polymerization and melting-down were shown to be the most thermostable. Chemical and thermal transformations in the intumescent systems were studied. Reaction mechanisms were not essentially affected by nanoclays added, whereas the coke layer becomes more stabilized at a temperature above 500 оС. Scientific novelty consists in that nanoclays added result in considerably increase fire-protective efficiency of intumescent system ammonium polyphosphate / pentaerythritol / melamin / polymer. Practical implications: the use of nanoclays as functional additives gives rise to an increase in fire-protective efficiency, environmental properties and performance characteristics of intumescent materials and coatings. The approaches used can be recommended as promising in development of economically attractive import-substituting production of organo-modified nanoclays and nanocomposites for intumescent coatings of new generation.
