FIRE-RETARDANT EFFICIENCY OF INTUMESCENTCOATING IN THE PRESENCEOF NANOSIZED COMPOUNDS UNDER HYDROTHERMAL AGEING
Journal Title: Вісник Одеського національного університету. Хімія - Year 2015, Vol 20, Issue 2
Abstract
The effects of the additives of nanosized organoclay and titanium oxide on performance of intumescent system were studied. It is shown that the additives of nano-sized compounds in fire-retardant intumescent composition increase its fire-protective efficiency and resistance to aggressive atmospheric factors. It was also found, that the disruption of the coating under hydrothermal ageing begins with elution of pentaerythritol and ammonium polyphosphate. The presence of organoclay and titanium nano-oxide significantly retards the process of decomposition. It was determined that the fire-resistance efficiency of intumescent composition with cetyltrimethylammonium-montmorillonite additives is the highest among the tested systems.
