Al(OH)3及其复合阻燃体系对电缆护套料阻燃和力学性能的影响
Effects of Al(OH)3 and Its Composite Flame Retardant Systems on Flame Retarding Performance and Mechanical Properties of Cable Jackets
【摘要】 研究了氢氧化铝-氢氧化镁[Al(OH)3-Mg(OH)2]和Al(OH)3-有机蒙脱土(OMMT)这两种不同的阻燃体系以及不同生产工艺制备的单组分Al(OH)3对电缆护套料的阻燃性能和力学性能的影响。结果表明,Al(OH)3和Mg(OH)2的添加量为1∶1时,电缆护套料的阻燃性能达到比较理想的效果;加入3%的OMMT能与Al(OH)3在燃烧过程中产生良好的协同效应,生成致密且坚固的炭层,改善了电缆护套料的阻燃性能;不同生产工艺制备的Al(OH)3用作电缆护套料的阻燃剂,能明显提高其阻燃性能。
【Abstract】 Three kinds of retardant systems,single-component Al(OH)3,Al(OH)3-Mg(OH)2,and Al(OH)3-OMMT,were applied in cable jacket material and their effects on flame retarding performance and mechanical properties were studied.When the weight ratio of Al(OH)3 and Mg(OH)2 was 1∶1,these materials have good flame retardant property.A synergistic effect between Al(OH)3 and OMMT was confirmed by the formation of compact charred layer.Single-component Al(OH)3 also showed a significant effect on flame retardancy.
