| 摘 要：通過(guò)在丁腈橡膠（NBR）／氯化聚丙烯（CPP）橡塑復合材料中添加協(xié)同阻燃劑三氧化二銻，制備了阻燃型NBR／CPP橡塑復合材料，考察了三氧化二銻用量對NBR／CPP橡塑復合材料硫化特性、力學(xué)性能和燃燒性能的影響。實(shí)驗結果表明：三氧化二銻的加入沒(méi)有降低NBR／CPP橡塑復合材料的加工性能；當三氧化二銻用量為10.0份時(shí)，NBR／CPP橡塑復合材料的拉伸強度、300%定伸應力和邵氏硬度分別增加了15.7%、112%和10.9%；復合材料的氧指數（LOI）隨三氧化二銻用量的增加逐漸增大，當三氧化二銻用量為2.5份時(shí)，復合材料氧指數為27.4%，達到自熄級阻燃效果。 |

| Abstract：The flame-retardant acrylonitrile-butadiene rubber（NBR）／chlorinated polypropylene（CPP）rubber-plastic composites were prepared by adding antimony trioxide（Sb2O3）which is synergistic flame-retardant. The influences of the loading of Sb2O3 on curing characteristics，mechanical properties and flammability properties were evaluated. The experimental results showed that the processability of the blend system was not reduced with the increase of Sb2O3 loading. When the loading of Sb2O3 was at 10.0 phr.，the tensile strength，300% modulus and Shore A hardness of the composites were respectively improved by 15.7%，112% and 10.9%. The limiting oxygen index（LOI）of the composites was increased with the increase of Sb2O3 loading. When the content of Sb2O3 was 2.5 phr，the LOI of the composites was up to 27.4%，which indicated that the inflammability of the composites was distinctly enhanced. |
