摘要
将氢氧化铝和碳酸镁复配添加到线性低密度聚乙烯中,发现当氢氧化铝和碳酸镁的比例为4∶1时,其氧指数最高为26.碳酸镁和氢氧化铝复配阻燃聚乙烯具有协同作用.同时由于碳酸镁的加入还提高了体系的拉伸强度,但是却明显降低了断裂伸长率.
When are added to aluminium hydroxide and magnesium carbonate , LLDPE, if it＇s proportion is 4：1, the Oxygen Index reach to 26. Magnesium carbonate and aluminium hydroxide compound with flame-retardant polyethylene has synergism effect. And magnesium carbonate can improve the tensile strength, but reduce the elongation at break clearly.
