摘　　要：研究了氯化石蜡(CP)、双(六氯环戊二烯)环辛烷(DCRP)以及十溴联苯醚(DBDPO)并用阻燃低密度聚乙烯(LDPE)的阻燃协同效应,采用锥形量热仪测试了阻燃体系的燃烧特性。结果表明,CP与DCRP并用阻燃LDPE,明显降低了材料燃烧过程中的热释放速率、质量损失速率以及生烟速率,协同阻燃效果显著,CP与DCRP质量比为1∶1时,协同阻燃效果最好;DCRP与DBDPO并用阻燃LDPE,在很大程度上降低了材料燃烧后期的热释放速率、质量损失速率以及生烟速率,协同阻燃效果明显,且DCRP与DBDPO质量比为3∶2时,协同阻燃效果最佳;CP与DBDPO并用体系,协同阻燃效果不明显。The synergistic effect between chlorinate paraffin, dechlorane plus, decabromodiphenyl oxide and on fire-retardant properties of low density polyethylene was studied. The cone calorimeter was used to test the flammability of low density polyethylene. The results demonstrated that heat release rates, mass loss rates and smoke production rate of low density polyethylene retarded by chlorinate paraffin and decabromodiphenyl oxide were dis- tinctly reduced during the whole combustion period. When the mass ratio of chlorinate paraf- fin to dechlorane plus was 1： 1 ,the synergistic effect was the best. Meanwhile, the heat release rate,mass loss rate and smoke production rate of low density polyethylene retarded by dechlorane plus and decabromodiphenyl oxide during the later combustion period decreased obviously, and when the mass ratio of 3 ： 2 of dechlorane plus to decabromodiphenyl oxide was used, the synergistic effect of low density polyethylene was best. Additionally, when low density polyethylene retarded by chlorinate paraffin and decabromodiphenyl oxide, no synergistic effect appeared.
