摘　　要：通过Zr-801与α-甲基丙烯酸反应制得锆簇状化合物,将锆簇状化合物与红磷作为阻燃剂加入到聚丙烯(PP)中,制备了锆簇状化合物/红磷阻燃协效聚丙烯复合材料。通过对复合材料进行极限氧指数(LOI)测试、热重测试(TG)、拉伸强度测试及傅立叶变换红外光谱(FTIR)测试研究了复合材料的阻燃性能及其阻燃机理。结果表明:加入锆簇状化合物的复合材料LOI显著增加,材料的耐热性也有明显改善,且力学性能也有较大的增强;锆簇状化合物能促进固相成炭,改善材料的阻燃性能;锆簇状化合物质量分数为4.5%的锆簇状化合物/红磷阻燃体系的氧指数LOI最大可达25.5%。In this study, Zirconium clump compounds were synthesized by Zr- 801 and methylacrylic acid. The zirconium clump compounds/red phosphorus flame-retarded polypropylene composites were prepared by extruder and curing press machine using zirconium clump compounds and red phosphorus as flame retardant. The flame-retardant performance was studied by limit oxygen index（ LOI）, thermogravimetry （TG）, tensile strength test and Fourier transform-infrared spectroscopy （FTIR）. It was found that the zirconium clump compounds could increase the thermal stability and char residue. Especially, when the addition amount of zirconium clump compounds was 4. 5 % , the LOI of composites can reach up to the maximum with 25.5 %.
