Abstract

With iron sulfate and aluminum sulfate as raw materials,iron aluminate flame retardant was prepared using acti-vated carbon treated with phosphoric acid as template.The prepared iron aluminate was investigated by X-ray diffraction(XRD) and infrared spectroscopy(FT-IR).The flame retardant and smoke dissipation property of iron aluminate flame retar-dant on flexible polyvinyl chloride(PVC) were characterized by the limiting oxygen index test(LOI) and smoke density test(SDR).The results showed when the amount of 5%(mass fraction) iron aluminate was used,LOI and SDR was 32.8% and 55.45%,respectively,tensile strength was 18.36 MPa,elongation was 214%.The thermal degradation of flame retardant PVC were studied by using thermal analysis(TG).The results demonstrated that iron aluminate can be used as a highly effective flame retardant for flexible PVC.
