The purpose of research - development of scientific approaches to the development of new coatings intumescent type containing no halogen flame retardants, with elevated fire retardant, environmental and performance through the study of the effect of nanoclay on the structuring of the intumescent system definition - endo and exo components of toxic and dangerous products intumescent coatings thermolysis method in silico results by QSAR analysis. The study of the physicochemical properties and the study of bentonite clay deposits Dashukovskie structure, synthesis technique developed montmorillonite modified cation tallow bis-hydroxyethylmethyl ammonium. It is found that the impurities in the intumescent composition organoclay composition of the ammonium polyphosphate / pentaerythritol / melamine / styrene-iso-butyl methacrylate positively affect rheological properties of the original paint and the formation of coke on the coating layer in the temperature range of 400-600 ° C. It is shown that the addition to organoclays intumescent composition in an amount of not more than 1% leads to a shift of carbonized polymer residue oxidation temperature in a high temperature region decreases with minimal volume swelling ratio and increase coke mass by 10-20%. It was determined that the replacement of chlorinated paraffin in the organoclay in the formulation borne intumescent paints significantly alters performance endo and exo acute toxicity, both in terms of the coating operation and in unexposed. The calculated total index of danger studied intumesсent paint allows to relate it to the hazard class IV. The research results have scientific significance for the development of theoretical approaches to the design of building purpose materials with improved fire retardant characteristics through the application of environmental and budgetary nanotechnology. The practical significance of the work lies in the possibility of the introduction of new high-tech fire-resistant coating designed to provide the high limits of fire resistance of constructions - R 60-R 90. The used approaches can be recommended as promising in the development of cost-effective technology import-substituting production of modified nanoclays and nano-additives for new generation intumescent coatings.
