摘要: Abstract The thermal properties of residual char basalt fiber (BF) reinforced intumescent coating (IC) obtained after high temperature burning were studied. Seven formulations prepared in which the weight percentage is varied from 0 to 3 wt.% total formulation. effects BF on fire resistance IC, and morphology composition also heat barrier effect was analyzed by using a Bunsen burner (ASTM E119). Field emission scanning electron microscopy (FESEM), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) used investigate IC chars. Furthermore, conductivity calculated as function compare structure residues. Intumescent chars with different percentages BFs (in particular formation pores sizes) firstly verified. interpretations not agreement data. IC-B3 formulation that contains had value 0.114 Wm−1 K−1. morphological study confirmed formed network protected underlying steel substrate rise event fire. TGA results showed formulations; 36.26% at 800 °C compared IC-B0, 27 wt.%. Elemental enhanced carbon content 63.1% char. Pyrolysis-gas chromatography-mass spectrometry (Pyrolysis-GCMS) revealed suppressed release toxic gases IC-B0 average released decreased 83.3%–57.1%.
