The Synergistic Effect of Intumescent Fire‐Resistive Paint Containing TiO₂ Nanoparticles and Chlorinated Paraffin onto Atmospheric‐Metallic Substrates

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.

The catalytic performance of CuFe2O4@CQD nanocomposite as a high-perform heterogeneous nanocatalyst in nitroaniline group reduction

“…To enumerate the crystallite size of CuFe 2 O 4 @CQD nanocomposite, the Debye–Scherrer’s formula could be calculated as follows 65 , 66 : where , , , , and are ascribed to the average crystallite size of NPs (nm), the wavelength of the X-ray pattern, the full width at the half apex of the maximum diffraction (FWHM), and the Bragg angle. This peak corresponded to the reflection of the (002) plane of carbon quantum dots, confirming the accurate fabrication of nanocomposite.…”

UV-shielding properties of a cost-effective hybrid PMMA-based thin film coatings using TiO2 and ZnO nanoparticles: a comprehensive evaluation

“…The remarkable reduction of the UV-exposed sample within λ = 300 nm and λ = 344 nm range can be explained due to the inconsistent dispersion and agglomerated nanoparticles on the surface of PMMA. Agglomeration is one of the major factors regarding reflection capability and transmission; thus, inconsistent dispersion alongside UV irradiation, which enhances the agglomeration process, resulted in reduced absorbance 34 , 35 .
