A Study of Using ZnB Nanoparticles and SWCNT to Enhance Flame Retardance of Fire-retardant Coating
This study explores the effects of the flame-retardant properties of nano-particles on water-based fire-retardant coating. The water-based coating used in the paper is a water-based fire-retardant coating composed of itumescent fire retardant, single-wall carbon nanotubes of different concentrations, and ZnB nanoparticles. Thiis paper tests the thermal stability and combustion characteristics of the water-based fire-retardant nano-coating. The experimental results show that when the fire-retardant nano-coating is added with 4% of SWCNT, the residue amount of coating is 37.48% under the condition of testing temperature at 580 °C. When the testing time is at the 558th second, the maximum heat release rate produced is 256.69 kW/m2. In addition, when the fire-retardant nanocoating is composed of 10% of ZnB, the residue amount of the coating can be increased by around 75% under the condition that the combustion temperature is 580 °C. When the testing time is at the 470th second, the maximum heat release rate produced is 281.67 kW/m2.
