AI Technical Summary
Current fire-resistant coatings and additives for materials are inadequate in providing comprehensive fire and heat resistance, as they either rely solely on chemical or physical components, which are not sufficient to effectively reduce ignitability and heat release rates, and may also produce toxic fumes when burning.
A fire-resistant composition combining an intumescent base material with a flame spread reduction material, oxygen reduction agent, thermal transmission reduction agent, and refractory fibers, along with optional components like foaming agents, charring agents, and mechanical enhancers, to create a multi-layered protective barrier that enhances fire resistance and heat insulation.
The composition achieves significant fire resistance by reducing flame spread, peak heat release rates, and smoke production, while maintaining structural integrity and protecting underlying materials from high temperatures, as demonstrated through various testing scenarios.
