| 摘 要： | 采用纳米氢氧化镁对高密度聚乙烯（ HDPE）进行阻燃改性。通过氧指数法，垂直燃烧法和力学性能测试方法研究了改性材料相应性能的变化。结果显示改性后的HDPE氧指数比未改性前提高30％以上，燃烧等级提高到UL－94 V2级，拉伸强度有所增加，但拉伸应变下降较多。氢氧化镁对改善燃烧性能有帮助，同时也提高了HDPE的尺寸稳定性。

| Abstract: | Nano-magnesium hydroxide （ NMH ） was adopt to improve fire performance of HDPE.Limited oxygen index, UL-94 rating and mechanical property were studied.The results showed that LOI, UL-94 and tensile strength were improved, while tensile strain was decreased. NMH represented good fire retardancy, which was helpful for dimensional stability of HDPE. |
