EFFECTS OF HALOGENS ON PYROLYTIC GAS FORMATION FROM CELLULOSIC FIBERS

抄録

Effect of halides and halogen-nitrogen compounds treatment on pyrolytic gas formation from cellulosic fibers was studied by gas chromatography and mass spectroscopy. While treatments with sodium halides were not effective in improving flame retardancy, ammonium halides, ammonium bromides in particular, with high Limiting Oxygen Index (LOI) were highly effective in flame retardation and in reducing generation of flammable gases and poisonous gases, especially acrolein. The results showed the synergistic effect of halogen and nitrogen in the treating compound, similarly in the case of phosphorus and nitrogen studied previously.
