Nano Composite of Clay and Modified Ketonic Resin as Fire Retardant Polyol for Polyurethane

In situ modified cyclohexanone-formaldehyde resins
were prepared by addition of alendronic acid during resin
preparation. Clay nanocomposites in ketonic resins were achieved by
adding clay into the flask at the beginning of the resin preparation.
The prepared resins were used for the synthesis of fire resistant
polyurethanes foam. Both phosphorous containing modifier
compound alendronic acid and nanoclay increases fire resistance of
the cyclohexanone-formaldehyde resin thus polyurethane produced
from these resins. The effect of the concentrations of alendronic acid
and clay on the fire resistance and physical properties of
polyurethanes was studied.
