| Summary: | The use of structural steel in construction of buildings is increasing progressively due
to its strength. In case of fire, structural steel loses its loadbearing capability at 550°C.
Intumescent fire retardant coating, a passive fire protection system is used to protect
the steel substrate in fire. In present research work, a control formulation consisting of
ammonium poly-phosphate as acid source, expandable graphite as carbon source,
melamine as blowing agent, boric acid as additive and hardener H-2310 polyamide
amine as curing agent in bisphenol A epoxy resin BE-188(BPA) was developed. This
control formulation was further reinforced with slicate minerals, such as wollastonite
and clay minerals. A range of formulations were developed by varying wt. % of fillers
to examine their effects toward heat shielding, char expansion, char composition,
toxicity and char morphology. |
