摘　　要：用微胶囊化红磷(MRP)作为阻燃剂,利用双螺杆挤出机制备了阻燃HDPE/MRP共混物,并首次使用点燃氧指数和燃烧氧指数来表征它们的阻燃性能。结果表明:添加少量的PA6可提高HDPE/MRP复合材料的阻燃效果,固定PA6与MRP的添加总量为15%,且在HDPE∶PA6∶MRP=85∶4∶11时,其极限氧指数最大,为22.1%;在固定MRP含量的情况下,随PA6含量的增加,HDPE/PA6/MRP复合材料的阻燃性增强。h was about the HDPE to be flame retarded by micro-encapsulated red phosphorus mother granule （MRP）, firstly using burned oxygen index and ignited oxygen index to characterize their combustion properties respectively. Adding a few PA6 could improve the flame retardantcy of the HDPE/MRP composite. When total additian of PA6 and MRP was 15% and HDPE： PA6： MRP = 85：4：11 ,the limit oxygen index reached maximum,which was 22.1%. Under the situation of fixing MRP contents,with the in creasing of PA6 contents,the flame retardancy of HDPE/PA6/MRP composites inproved.
