Phosphorus nitrogen groups first decomposition flame retardant in epoxy resin plays a very important role, because the phosphorus-containing substances containing nitrogen and phosphorus compounds decomposition heat of formation of polyphosphates, poly partial phosphate enrichment and to cover the surface of epoxy resin, not only from the air, the epoxy resin layer and further prevent fuel combustion combustion fabric, but also conducive to the promotion of epoxy resin dewatering charring effect. Nitrogenous substance formed a N2 or NH3, the protective layer expansion and distribution has the effect of dilution and isolation of oxygen in the air in the protection layer and interna

The decomposition of radical groups that contain phosphorus and nitrogen exert great effects on inflaming retarding of epoxy resin, because after the thermal decomposition of chemical compounds, the materials that contain phosphorus usually form gathering of polyphosphates and polyvinylidene phosphates which cover the surface of epoxy resin. This can not only insulate the air but also protect the burning zone of epoxy resin and prevent further burning of the inflammables. It can also contribute to the dehydration and carbonization effects of epoxy resin. And the materials that contain nitrogen form N2 or NH3, making the protection layer swell and spreading upon and inside the protection layer, which dilutes and insulates the oxygen in air.
