Abstract
To enhance the efficacy of flame retardants and their resistance to water in conventional formulations, this work introduces a microencapsulation method to modify the surface of piperazine pyrophosphate (PAPP). This approach improves the compatibility of PAPP with rigid polyurethane foam (RPUF) and incorporates hydrophilic silicone gel (generated SiPAPP), enhancing both flame retardant performance and the synergistic interaction among phosphorus, nitrogen, and silicon elements. Additionally, iron oxide nanoparticles (Nano-Fe 2 O 3 ) are used to modify the flame retardant surface post-microencapsulation (named as SiPAPP@Fe 2 O 3 ) to further suppress smoke release. Results indicate that SiPAPP@Fe 2 O 3…
