Preparation of intumescent flame retardant poly(butylene succinate) using fumed silica as synergistic agent / Yangjuan Chen in Industrial & engineering chemistry research, Vol. 49 N° 17 (Septembre 1, 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 17 (Septembre 1, 2010) . - pp 8200–8208 Titre : Preparation of intumescent flame retardant poly(butylene succinate) using fumed silica as synergistic agent Type de document : texte imprimé Auteurs : Yangjuan Chen, Auteur ; Jing Zhan, Auteur ; Ping Zhang, Auteur Année de publication : 2010 Article en page(s) : pp 8200–8208 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Silica  Synergistic  agent. Résumé : A novel intumescent flame retardant (IFR) poly(butylene succinate) (PBS) with an antidripping property using fumed silica as a synergistic agent was prepared. Ammonium polyphosphate, melamine, and fumed silica were added in PBS via melt blending. It was revealed that the flame retardant PBS exhibited both excellent flame retardance and antidripping properties when the three components of IFR coexisted at an appropriate proportion. The lowest total loading of flame retardant could be reduced to 17 wt % with the synergism of fumed silica, for the goal of vertical flammability (UL-94) V-0 rate. Scanning electron microscopy and X-ray photoelectron spectroscopy were employed to characterize the morphology and composition of residual char, respectively. The combustion properties and thermal degradation behavior of the IFR-PBS composites were fully evaluated, and the possible flame retardant mechanism was proposed.
