| 摘 要： | 通过熔融插层法制备了高密度聚乙烯（PE-HD）/膨胀型阻燃剂（IFR）/有机蛭石（OVMT）阻燃复合材料，探讨了IFR中聚磷酸蜜胺（MPP）与季戊四醇（PER）质量比对复合材料阻燃性能以及OVMT添加量对熔融插层效果的影响。实验数据显示，在阻燃剂为30质量份的情况下，复合体系IFR中MPP与PER的最佳质量比为3：1，OVMT添加量为2 %（质量份，下同）时熔融插层效果最好。此时PE-HD/IFR/OVMT体系 （70/28/2）的极限氧指数为28.6 %，垂直燃烧（UL94）等级达到V-1级。此外，实验还表明，适量增容剂高密度聚乙烯接枝马来酸酐（PE-HD-g-MAH）对熔融插层效果有促进作用。

| Abstract: | Flame retarding composites of high density polyethylene(PE-HD)/intumescent(IFR)/or- ganic vermiculite(OVMT)were prepared via direct melt intercalation.The effect of the ratio of melamine polyphosphate(MPP)to pentaerythritol(PER)in the intumescent on composite's flamma- bility and the effect of the loading of OVMT on the melt intercalation were investigated.It was found that the best weight ratio of MPP/PER was 3:1 at a loading of flame retardant of 30 wt %.The best intercalation result was achieved with 2 w... |
