The research purpose is the study of the impact of nanomaterials on the durability of intumescetn coatings with the establishment of the operation life by the method of accelerated climatic tests. Research methods: IR spectroscopy (for identification of chemical structure), flame tube experiments and full-scale fire tests (studies on fire protective efficiency of coatings), method ETAG 018-2 (for predicting the operation life). The addition effect of cetyltrimethylammonium-montmorillonite and nanostructured titanium oxide into ammonium polyphosphate / pentaerythritol / melamine / ethylene vinyl acetate copolymer system for durability intumescent coatings for metal and wood building constructions was investigated. Accelerated climatic tests for intumescent coatings for metal construction by standard ETAG 018-2 were carried out, a group of fire protective efficiency for wood in the processing of intumescent paints with additives nanoclays was identified. It has been shown that the presence of modified clays in paints for wood leads to a significant reduction in temperature of exhaust gases by the action of the open flame onto the sample. Chemical transformations in intumescent systems in operation in confined areas without significant changes in temperature and humidity, as well as under hydrothermal effects. was studied by IR spectroscopy. Scientific novelty consists of the conclusions: additives nanomaterials slow washing out ammonium polyphosphate and pentaerythritol out of coating, as well as the degradation of the polymer; adding to the intumescent system nanooxides and nanoclays prolongs the operation life of the coating for three years; intumescent coating involving cetyltrimethylammonium montmorillonite provide longer operation life and higher fire-protective properties. The practical significance of the research is the fact that the use of nanomaterials as additives can simultaneously improve the weather resistance, durability, fire retardant efficiency, environmental properties and other performance characteristics of such intumescent coatings.
