摘　　要：利用次磷酸铝(AHP)、聚磷酸铵(APP)、三聚氰胺(MN)改性竹粉/聚丙烯木塑复合材料(WFC),发现AHP、APP和MN三者复配具有提高WFC的热稳定性和高温残炭生成量的协同作用,且可抑制WFC在燃烧时生成滴落物,提升WFC的阻燃性能。当AHP、APP、MN三者复配的质量比为10∶7∶3,添加量为20wt%时,所制木塑复合材料AHP_(10)/APP_(7)/MN_(3)/WFC在700℃时的残炭量是WFC的两倍,相较于WFC,极限氧指数值提升21%,达26.4%;由垂直燃烧UL-94阻燃无级别提升至最高级别V-0级,且保持84.4%的冲击强度。Aluminum hypophosphate(AHP),ammonium polyphosphate(APP) and melamine(MN) were used to modify bamboo powder/polypropylene wood-plastic composite(WFC).It was found that the combination of AHP,APP and MN had a synergistic effect on improving the thermal stability of WFC and the generation of high temperature carbon residue,could inhibit the formation of droplets during combustion of WFC,and improve the flame retardancy of WFC.When the mass ratio of AHP,APP and MN was 10∶7∶3 and the addition amount was 20wt%,the carbon residue of AHP_(10)/APP_(3)/MN_(7)/WFC at 700 ℃ was twice that of WFC.Compared with WFC,the limit oxygen index value was increased by 21%,reaching 26.4%.It could reach the highest flame retardant grade in the vertical combustion UL-94 test of V-0 rating,and maintain 84.4% of the impact strength of non-flame retardant WFC.
