摘　　要：将Sb2O3、Fe2O3、聚磷酸铵(APP)、镁铝类水滑石(MgAl-LDHs)、APP-LDHs、ZnO、硼酸锌等无机物分别与十溴二苯乙烷(DBDPE)复配,并与聚丙烯(PP)熔融共混制备DBDPE/协效剂/PP阻燃复合材料;采用极限氧指数(LOI)、垂直燃烧测试(UL-94)、缺口冲击、弯曲实验等方法研究了协效剂对DBDPE/无机协效剂/PP阻燃复合材料的阻燃性能及力学性能影响;采用能谱(EDX)分析样品的成分,探索APP与DBDPE复配阻燃的协效原理。结果表明,Sb2O3与DBDPE协效阻燃效果最好,APP的复配效果次之;APP与DBDPE的协效主要为体系中的磷、氮、溴元素的共同作用。Several inorganic substances, such as Sb2O3, Fe2O3, ammonium polyphosphate （APP）, MgAl layered double hydroxides （MgAl-LDHs）, APP-LDHs, ZnO, zinc borate, used as synergist were compounded with decabromodiphenylethane （DBDPE）, respectively, and the DBDPE/Synergist/PP flame retardant composites were prepared by compounding the synergist, DBDPE and PP via melt blending. The UL-94 vertical burning test, limiting oxygen index （LOI） and tensile, flexural and notch impact test were used to investigate the influences of synergist on the flame retardant and mechanical properties of DBDPE/Synergist/PP composites. Additionally, the energy dispersive X-ray （EDX） was employed to study the synergistic mechanism of the compounding of APP and DBDPE. The results demonstrate that the synergistic retardant effect of Sb2O3 and DBDPE is the best and that of APP and DBDPE take second place. The synergistic retardant of APP and DBDPE mainly attributes to the combined effect of phosphorus, nitrogen and bromine elemental.
