3D-map modelling for the melting points prediction of intumescent flame-retardant coatings

Abstract The applicability of 3D map modelling for melting point prediction was studied. The melting points in the ammonium polyphosphate–pentaerythritol–melamine chemical system of intumescent flame-retardant coatings over a wide range of concentrations were collected. The ternary diagram (triangle) of the melting points was plotted and an approximated 3D map was built for the range 205–345°C. The present work contains the thermal data for the observed ternary system and provides a new graphic system for making predictions for intumescent flame-retardant coatings. The applicability of the calculated 3D map for obtaining experimental samples of fire-retardant paints with a low melting point for thin steel constructions was shown.
