Effects of carbon materials on fire prevention and smoke suppression.

Scientists have studied the effects of carbon materials on fire prevention and smoke suppression in water-based expansion coatings.
new carbon materials, especially carbon nanomaterials, have made significant progress in refractable coatings and technologies. To improve fire resistance, inflated graphite (EG), carbon nanotubes (CNT), Fullerene (C60) and graphene (Gr) are used as fillers in water-based expansion coatings to study refraction, thermal stability, smoke suppression and water resistance .
through flame retardant testing, thermal re-analysis (TG), differential scanning volume heat meter (DSC), flue gas density test and water resistance test, the impact of carbon materials on water-based expansion coating fire prevention and smoke suppression was studied in detail.
carbon layer is represented by scanning electron microscopes (SEMs), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), and particle size distributions.
the refracessability of the coating
fire testing and SEM results show that adding 1% carbon material can improve the fire resistance of the coating. TGA analysis shows that carbon materials can increase the residual weight and thermal stability of the coating. After 360 hours of immersion in water, the carbon material may form a barrier layer, which improves the water resistance of the coating. In particular, graphene performs best in all carbon materials.
