Strontium Hydroxystannate Nanorods Encapsulated by Hybrid Polyphosphazene: Synthesis and Flame Retardancy on Epoxy Resin
Source abstract
Abstract
To develop a novel hybrid organic-inorganic flame retardant and smoke suppressant, strontium hydroxystannate (SrSn(OH) 6 ) nanorods were synthesized via a co-precipitation method, and then the SrSn(OH) 6 were encapsulated by cyclomatrixpolyphosphazene (PZS) to prepare a novel core-shell organic-inorganic hybrid nano-flame retardant (PZS@SrSn(OH) 6 ). The micromorphology and chemical structure were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and fourier transform infrared spectroscopy (FT-IR). The thermal degradation of PZS@SrSn(OH) 6 and EP/PZS@SrSn(OH) 6 composites was investigated by thermogravimetry analysis (TGA). The flame retardancy properties were studied by limited oxygen index (LOI) and CONE calorimetry tests. The flame retardant mechanism was determined by X-ray diffraction (XRD), SEM, energy-dispersive X-ray spectroscopy (EDS), and FT-IR.
