The research content is to develop nanocomposite coatings to provide fire resistance to structural steel substrate.This study presents the results of the different formulations developed to study the effects of nanoclay on coating expansion and thermal shielding during the fire test. The anti-fire effect of nanocomposite coating is improved by 5 wt.% dispersed nanoclay particles. The coatings are characterized by using scanningelectron microscope (SEM), Flame-retardant evaluation methods: LOI, UL 94 rating. Effect of additional content of nanoclay on combustion efficiency is studied by flame retardant test and measurement of limited oxygen index and effective thermal conductivity.
Key words: Flame retardant, nanoclay, nanocomposites, limiting oxygen index.
