无卤阻燃PA10T力学性能及热稳定性研究

摘要

Poly ( decamethylene terephthalamide ) ( PA10T) was flame-retarded by using a kind of metal phosphinate (FR-Phosphite ). The influence of FR-Phosphite content on the mechanical property of PA10T was studied, and the degrading behavior of PA10T with different content of FR-Phosphite was analyzed. The results showed that the tensile strength of PA10T firstly increased and then decreased with increasing the content of FR-Phosphite. It was found that the starting degradation temperature of PA10T reduced with adding FR-Phosphite.%采用一种次膦酸金属盐阻燃剂( FR-Phosphite)对聚对苯二甲酰癸二胺(PA10T)进行阻燃改性.研究了阻燃剂含量对改性PA10T力学性能的影响,并分析了不同阻燃剂含量时阻燃PA10T的热降解行为.结果表明,随着阻燃剂含量的增加,阻燃PA10T材料的拉伸强度呈现先上升后下降的趋势；阻燃剂FR-Phosphite降低了PA10T的初始降解温度.
