Enhancing the flame-retardant performance of wood-based materials using carbon-based materials

We sought to improve the flame-retardant performance of wood-based materials through the development of a coating material using carbon-based materials. The coating materials were applied to the surfaces of wood-based materials used for interior materials and furniture. We measured fire characteristics of the coated wood-based materials using a cone calorimeter. The coating materials were prepared by the mixing of carbon materials, such as natural graphite, expandable graphite, and exfoliated graphite nanoplatelets, in water-based coating materials. TG analysis revealed that water-based coating materials/carbon material-blended composites had good thermal durability in the working temperature ranges. The flame-retardant performance was confirmed through cone calorimeter experiments, and the result of the experiment satisfied the standard for flame-retardant performance in ISO 5600-1.
