Sažetak
Increasing demand for polymer materials brings new problems ; the most important disadvantage of these materials concerns their low thermal resistance and fire behaviors. For this reason, flame retardants are used. Flame retardants are chemical compounds that modify pyrolysis reactions of polymers by slowing down or by inhibiting them. Most frequently used are phosphorus, aluminium, chlorine and boron-containing compounds. Today using of halogenated compounds is avoided due to degradation products which bring environmental and health concerns. In this work effect of fillers on flammability of polystyrene composites was studied. Series of polystyrene (PS) composites containing different concentrations (2 to 8 wt %) of micro- or nanofillers were prepared by extrusion. Aluminium hydroxide Al2(OH)3 was used as microfiller, and hydrophobic fumed silica Aerosil, SiO2 was used as nanofiller. It is known that flame retardants affect mechanical properties and the interface at the surface of particle inclusions plays a key role in the structure property relationship of polymer composites. For this purpose mechanical properties (tensile strength and elongation at break) of the studied samples were determined. The dispersion of filler in polystyrene matrix is important for fire retardant efficiency and was examined by scanning electronic microscopy (SEM). Flammability characterization of studied polystyrene composites was carried out by vertical burning test UL 94 (IEC 60695-11-10 ; ISO 1210
