The goal of the investigation is to study the effects of nano analogs of metal oxides and hydroxides on fire protective efficiency of the composites involving ethylene-vinylacetate copolymer and intumescent system ammonium polyphosphate/pentaerythritol/melamin and development of new technological solutions for reduction of combustibility of polymer materials and intumescent fire protective coatings. Research methods: IR spectroscopy (for identification of chemical transformations mechanism), flame tube experiments and thermogravimetry (studies on fire protective efficiency of antipyrens). Intumescent systems were studied at a wide variation in metal oxides and hydroxides and their nanoscaled analogs; a comparison examination of the effects of antipyrens on the formation and oxidation of polymeric coke layer was carried out over a temperature range 200 600 0С. The mixtures involving nano-particles of titanium and zinc oxides were found to be the most efficient. The novelty of the research is that the admixtures of nano oxides cause a considerable increase in fire protective efficiency of intumescent composite ammonium polyphosphate / pentaerythritol / melamin/ copolymer of ethylene with vinyl acetate. The most probable mechanisms of interaction of metal-containing compounds with copolymer and ammonium phosphate, which are responsible for thermal stability and mechanical strength of the coke residue, were established. Practical implication is concerned with an improvement of thermostable fire-safe polymers and fire-protective polymer coatings. Product Description popup.authors Бєлоусова І.О. Вахітова Л.М.
