Abstract
Abstract This research aimed to investigate the impact of diverse formulations of paints for atmospheric‐metallic substrates. TiO 2 nanoparticles (NPs) and chlorinated paraffin (CP) were utilized as modifiers to develop the fire protection feature of intumescent fire‐resistive paints. The best formulation of the fireproof paint was the simultaneous use of 3.9 wt % TiO 2 nanoparticles and 9.3 wt % CP. The synergistic impacts on the paint characteristics were studied in detail by TGA, FTIR, SEM, XRD, and Bunsen burner tests. The TGA outcomes confirmed that adding TiO 2 NPs and CP could enhance the residue weight of the paints and increase the anti‐oxidation corresponding to the char layers at high temperatures. The SEM images showed that adding CP and TiO 2 NPs could enhance the carbonaceous layer surface structure, and the best outcome was attained by combining both synergistic agents.
