In this study, Polypropylene (PP) was used as a substrate to fill the environment-friendly inorganic phosphorus flame retardant, aluminum phosphate (AHP), and iron-graphene (IG) Spectrometer physical mixing, prepared PP / AHP / IG polymer flame retardant composite materials, preparation of test pieces, the thermal performance analysis, structural bonding analysis and combustion performance analysis. The FTIR analysis of iron-graphene showed that the functional groups of the Fe-graphene were reduced after the reduction. It can be proved that the reduction of graphene oxide by the Fe powder is effective. Scanning electron microscopy (SEM) showed that PP60-2 ~ PP60-5 with 60wt% polypropylene added showed that there were almost no holes on the surface of the carbon layer, which increased the surface density of the carbon layer and the carbon layers were stacked to form a layered structure. EDX shows that the content of each element of iron-graphene after reduction shows that C is the main component of graphene and that the characteristic peak of Fe can be observed. TGA showed that the initial degradation temperature dropped after the 40wt% aluminum phosphate flame retardant was added to the sample, and the residual carbon content increased from 1.5% up to 30.5%. The results of LOI and UL-94 show that the LOI value of the composites increases from 17% to 22% after adding 40wt% aluminum phosphate flame retardant. The LOI increases to 23% with the addition of trace iron-graphene and multi-layer graphene, is a self-extinguishing grade, UL-94 test from NR to V-0 level.
