AI Technical Summary
Existing triazine-based charring agents suffer from problems such as long synthesis time, high solvent consumption, insufficient thermal stability, low nitrogen content, low char yield, and poor flame retardant effect, which affect the flame retardant and mechanical properties of polymer materials.
A two-dimensional nano-carbonizing foaming agent with a nanosheet structure was prepared by reacting carbon-containing organic acids with melamine and metal ion aqueous solution. This agent was then compounded with ammonium polyphosphate to form an intumescent flame retardant system, which was then used to blend with polymers to form flame retardant composite materials.
It achieves flame retardant effects with high nitrogen content, rapid foaming into char, good compatibility, and low cost, improves the flame retardant and mechanical properties of polymers, and the preparation process is environmentally friendly and simple.
