Recently, a well-known domestic material research team announced that it has successfully developed a highly efficient and environmentally friendly phosphorus-nitrogen flame retardant in the field of intumescent coatings, which significantly improved the fire resistance and environmental friendliness of the coating. Through the synergistic effect of phosphorus and nitrogen elements, the flame retardant quickly forms a dense carbonized layer at high temperature, effectively insulating heat and flames, while releasing inert gases to inhibit combustion reactions.
Compared with traditional halogen flame retardants, phosphorus-nitrogen flame retardants are not only non-toxic and pollution-free, but also have higher thermal stability and flame retardant efficiency. Experimental data show that the expansion ratio of intumescent coatings with the addition of this flame retardant at high temperatures has increased by 30%, and the fire resistance time has been extended by more than 40%.
This breakthrough provides a more reliable solution for fire safety in the fields of construction, ships, etc., and also promotes the intumescent coating industry to move towards green and environmental protection. In the future, the team plans to further optimize the formula and promote the large-scale application of phosphorus-nitrogen flame retardants.
