摘要 采用极限氧指数、锥形量热计和热分析等手段 ,研究了氢氧化镁 (MH)和其他类型的无卤阻燃剂在硅烷交联聚乙烯 (SXPE)体系中的阻燃协效作用。氧指数实验结果表明 ,硅烷交联的聚乙烯 /氢氧化镁 (SXPE/MH )体系的氧指数高于未交联的PE/MH体系的氧指数 ,若在SXPE/MH阻燃体系中添加适量的其他无卤阻燃剂 ,如磷氮类化合物 (NP 2 8)和氮类化合物 [三聚氰胺氰尿酸盐 (MCA) ]氧指数都有提高。锥形量热计实验结果表明 ,在SXPE/MH阻燃体系中添加适量的NP 2 8或MCA ,体系的着火时间有所延长 ,热释放速率和发烟量也有不同程度的降低。热分析实验结果显示 ,NP 2 The synergistic effect in flame retardacy of magnesium hydroxide (MH) and other halogen-free flame retardants (HFFR) was studied for PE systems.At the same MH content,the LOI value of silane crosslinked PE was higher than that of uncrosslinked.The introducing of a phosphorus and nitrogen containing compound (NP-28) or melamine cyanurate (MCA) may further increase the LOI.The cone calorimeter test (CCT) showed that NP-28 or MCA also resulted in delay of ignition,decreases in the heat release rate and smoke emission.TGA tests showed that NP28 and MCA had some effects on the thermal stability of the silane crosslinked PE/MH blends.
