摘要:

采用熔融共混法制备了玻纤和碳纤协同增强的抗静电聚酰胺66(PA66)复合材料,进一步将二乙基次膦酸铝(ADP)和三聚氰胺聚磷酸盐(MPP)阻燃剂引入抗静电PA66复合材料中,制备了无卤阻燃抗静电PA66复合材料,对其力学性能、电学性能和阻燃性能进行了表征。结果表明,随着碳纤含量增加,复合材料拉伸强度、弯曲强度和模量、冲击强度增加,其中10 %(质量分数,下同)碳纤和20 %玻纤增强复合材料具备良好的经济性和抗静电性能;MPP起到协效阻燃作用,大幅降低ADP添加量,13 %的ADP和2 %的MPP制备的复合材料3.2、1.6、0.8 mm样品阻燃达到V⁃0级,极限氧指数为34 %。

Abstract:

Glass fiber⁃ and carbon fiber⁃reinforced antistatic polyamide 66 (PA66) composites were prepared via melt blending. Halogen⁃free flame⁃retardant antistatic PA66 composites were subsequently fabricated by incorporating aluminum diethylphosphinate (ADP) and melamine polyphosphate (MPP) into the antistatic matrix. The mechanical, electrical, and flame⁃retardant properties of the composites were systematically characterized. Results indicated that the tensile strength, flexural strength, flexural modulus, and impact strength increased with higher carbon fiber content. A composite containing 10 wt% carbon fiber and 20 wt% glass fiber exhibited favorable economic efficiency and antistatic performance. MPP was found to synergize with ADP, substantially reducing the required ADP content. With the addition of 13 wt% ADP and 2 wt% MPP, the flame⁃retardant composites achieved a UL⁃94 V⁃0 rating at thicknesses of 3.2 mm, 1.6 mm, and 0.8 mm, along with a limiting oxygen index of 34 %.
