高灼热丝PET/PA6合金材料开发及应用

采用力学性能测试、扫描电子显微镜、灼热丝燃烧等手段，研究了有机磷酸酯、十溴二苯乙烷和无机氢氧化物3种阻燃体系对聚对苯二甲酸乙二醇酯/聚己内酰胺（PET/PA6）合金材料的灼热丝、阻燃及力学性能的影响。结果表明，十溴二苯乙烷和磷酸酯类阻燃剂复配使用时，灼热丝效果最好，能够达到灼热丝小于2 s的要求；PA6树脂的加入，提高了合金材料的灼热丝效果；甲基丙烯酸缩水甘油酯类增韧剂添加量在7 %时，合金材料的力学性能均衡，符合使用要求。

Research and Application of High Glow Wire Flame Retardant Enhance PET/PA6 Alloy Material

Three flame retardants, organophosphate, decabromdiphenylethane, and inorganic hydroxide were introduced separately into PET/PA blends and their glow wire property, flame retardancy, and the mechanical property were compared. The glow wire property, scanning electronic microscope and the mechanical test showed that the glow wire property was the best and the glow wire property was less than 2 second when a mixture of decabromdiphenylethane and phosphoric acid esters were used. PA6 played a positive role for the glow wire property. When the content of glycidyl methacrylate was 7 %, the blend exhbited optimal comprehensive mechanical properties.
