摘　　要：以聚磷酸铵和季戊四醇复配对丙烯酸丁酯-醋酸乙烯酯共聚乳液进行阻燃研究.通过极限氧指数(LOI)、垂直燃烧和热重分析等手段,对材料的燃烧性能以及热降解行为进行研究,采用扫描电镜对碳层结构进行表征.最佳LOI值可达28.9,并通过垂直燃烧V-0级别;同时,高温阶段碳层重量得到明显提高,且结构稳定.Ammonium polyphosphate and pentaerythritol were used to prepare halogen-free flame retardant BA-VAc copolymer emulsion.The flammability and thermal degradation properties of the copolymer were studied by using limited oxygen index（LOI）,vertical burning test（UL-94）,and thermo-gravimetric analysis（TG）.Morphology of residues was detected by means of scanning electron microscopy.The copolymer has the best LOI value of 28.9 and passes UL-94 V-0.TG data shows higher and more stable char residue in high temperature range.
