Abstract
This paper described the effect of reinforcement of an inorganic nano filler in intumescent fire retardant coating (IFRC). In this study, intumescent coating contained phosphorous, nitrogen and boron based compounds. Four formulations were developed in order to determine the thermal protective performance of coating. Furnace test was conducted to find out the intumescent factor. Bunsen burner test was conducted according to ASTM E-119 for thermal insulation of the coating. Further, char morphology and microstructure of char was examined by using field emission scanning electron microscopy. Fourier transform infrared spectroscopy was performed to confirm the chemical functional groups present in the char. Thermogravimetric analysis was carried out to determine the residual weight/thermal stability of coating. Tests revealed that coating containing 1.0 wt% of nano alumina as an inorganic filler provides better fire protection, char morphology and anti-oxidation property as compared to coating without containing nano alumina.
