摘　　要：通过对比不同包覆工艺红磷阻燃剂制备的红磷阻燃PA66的游离酸值与PH3的释放量,以及对应触点元件表面污染后的形貌和接触电阻,分析了使用不同红磷阻燃PA66作为壳体对交流接触器通电性能的影响,并模拟实际使用环境进行了实验。结果表明:使用多层包覆工艺的红磷阻燃PA66的游离酸析出少、PH3释放量低、对交流接触器的通电性能影响较小,可以作为交流接触器壳体的备选材料之一。The free acid value and PH3 release amount of PA66 prepared by red phosphorus flame-retardant with different coating process were compared,and the morphology and contact resistance of the corresponding contact element after surface contamination were tested.The effects of housing using different red phosphorus flame retardant PA66 on the electrical performance of AC contactor were analyzed,and the experiment of simulating the actual application environment was conducted.The results show that the red phosphorus flame-retardant PA66 using multi-layer coating process has low free acid value and PH3 release amount,which has little effect on the electrical performance of AC contactors and can be used as one of the alternative materials for AC contactor housing.
