Abstract

With the aim of reducing thermal hazards of polystyrene (PS), the traditional nitrogen-phosphorus intumescent flame retardant ammonium polyphosphate (APP)/dipentaerythritol (DPER) was improved. Three kinds of intumescent flame retardant were made which are melamine formaldehyde resin coated APP (MFAPP)/melamine formaldehyde resin coated dipentaerythritol (MFDPER), silane-modified APP/MFDPER, and silane-modified APP/triazine charring-foaming agent (CFA) respectively. After melt blending with PS, the combustion performance of samples were studied by limiting oxygen index (LOI) and cone calorimeter (CONE). The residual carbon of samples was studied by scanning electron microscope (SEM). The results how that the silane-modified APP can improve PS retardancy, CFA can effectively improve the carbon content of PS, silane-modified APP/CFA as IFR can improve PS retardant effectively.
