| 摘 要： | 研究了节能灯用玻璃纤维(GF)增强阻燃聚对苯二甲酸丁二酯(PBT)材料,分别探讨了新的阻燃体系,不同丙烯酸酯类增韧剂对其影响和材料的抗黄变问题。结果表明,新的阻燃体系溴代三嗪/三氧化二锑/OMMT阻燃效果较好,增韧剂中丙烯酸酯类接枝甲基丙烯酸缩水甘油酯(GMA)AX8900效果最好,其次为核壳结构丙烯酸酯类2M,最差为接枝MAH的丙烯酸酯类3M,但三者增韧效果差距不明显。抗黄变母粒的添加使得GF增强阻燃PBT材料在氙灯老化试验后颜色基本不变黄。

| Abstract: | Energy-saving lamp used glass fiber(GF) reinforced flame retardant polybutylene terephthalate(PBT)composites were studied,the impact of new flame retardant system and different acrylate toughening agent on composites and their anti-yellow problem were respectively investigaged.The results showed that new flame retardant system of brominated triazine/antimony trioxide/OMMT possessed better flame resistance,acrylate grafted glycidyl methacrylate(GMA) AX8900 had better toughening effect than core-shell structure acrylate 2M and MAH grafted acrylate 3M,but toughening effect gap among them was not obvious.Flame retardant PBT composites added with anti-yellow masterbatch showed essentially the same color after xenon lamp aging test. |
