“…Огнезащитное действие интумесцентных (вспенивающихся) покрытий заключается в том, что под воздействием высоких температур они образуют плотный теплоизолирующий вспененный слой кокса (пенококса), который служит барьером, препятствующим передаче тепла от В пламени к объекту защиты [3]. Основными параметрами, влияющими на огнезащитную эффективность, выступают теплофизические свойства образованного теплоизолированного слоя [4,5].…”

“…Огнетеплозащитное покрытие и установка для его получения). Проведенные исследования показывают, что введение углеродных наноструктур в матрицу огнезащитных вспучивающихся покрытий (ОВК) приводит к увеличению термической стабильности огнезащитного состава, плотности ОВК за счет наноармирования, тем самым уменьшению количества микротрещин, которые приводят к повышению скорости окислительно-восстановительной деструкции, а также усиливают адгезионую прочность покрытия [15][16][17][18]. Недостатком таких ОВК является высокая стоимость покрытия.…”

The problem of metal and wooden structure protection is one of the priority areas in fire safety. One of the most effective and affordable ways to make various materials fire-resistant is painting them with flame retardant paint and varnish materials. In this regard, in this area, the development of flame-retardant compositions and coatings with reduced flammability is underway. The most promising are flame retardant paint and varnish materials forming intumescent type coatings. These paint and varnish materials form a foam coated layer on the protected surface. This work is devoted to the research aimed at the development of new intumescent coatings based on organic-mineral matrix, characterized by low cost, comparable with analogues operational parameters and having a flame-retardant effect in the protection of wood and metal structures in case of fire. The paper considers the main components of flame-retardant intumescent coatings. The flame-retardant composition including organic and mineral components is selected. The technology of manufacturing samples with the necessary component mass fraction ratios in the mixture is considered. The research with the help of thermal analysis methods (differential-thermal and thermogravimetric) of the experimental sample with the following composition: epoxy resin ED-20 - 58.82 mass %, ammonium polyphosphate - 17.65 mass %, chrysotile asbestos - 11.76 mass %, dry potassium glass - 5.88 mass %, hardener polyethylene polyamine (PEPA) - 5.88 mass % has been carried out. The effect of flame-retardant composition components on the process of coke formation, degree of combustibility and smoke emission has been determined. The results of physical and chemical studies of the flame-retardant composite material are given. Ways of further flame-retardant composition improvement are determined.

The use of wood in structural and finishing materials can significantly reduce the time of building construction, but the high flammability of wood limits its use in the building industry. To increase fire resistance, wooden structures are impregnated with flame retardants and the penetrating ability depends on their structure. We present the results of a small-angle X-ray scattering study of the structure of flame retardants based on ammonium sulfate and phosphate. The radii of inertia of hydrated complexes formed when flame retardants are dissolved in water, their shape and type of chains along which hydrated ions are located are determined. It is revealed that the presence of diffraction maxima indicates the presence of an ordering in the arrangement of hydrated ions. Aqueous solutions of ammonium sulfate and disubstituted ammonium phosphate contain two types of hydrated complexes of the same shape but different radius of inertia. At the same time, hydrated ions in complexes are located along persistent chains, and ordering revealed in the arrangement of ions, depended on their type. The results obtained can be used in developing flame retardants with a reduced radius of inertia, which will increase the penetrating capacity of the processing solution and increase the fire safety of wooden structures.
