Abstract
A nanorod-structured strontium hydroxystannate [SrSn(OH)6] flame retardant was synthesized via a facile coprecipitation method and employed in epoxy resin (EP). Based on X-ray diffraction analysis, scanning electron microscopy, and transmission electron microscopy, the as-synthesized SrSn(OH)6 nanorods exhibited high crystallinity and uniform size distribution. The flame retardancy and smoke suppression properties of EP/SrSn(OH)6 composites were investigated by limiting oxygen index and cone calorimetry tests. The results showed that incorporation of SrSn(OH)6 led to a dramatic reduction of the fire hazards of EP, including a 21.9% maximum decrease in the peak heat release rate, a 33.3% reduction in the toxic CO yield, and a 133.3% increase in the char residue. In particular, this is the first attempt to evaluate the flame retardancy properties of SrSn(OH)6 nanorods in EP. The improved flame retardancy properties of the SrSn(OH)6 nanorods is attributed to their catalytic carbonization effect.
