摘　　要：以自制的长碳链聚醚酰胺弹性体(TPAE)为基体,通过加入不同种类的碱金属钠盐与锂盐,采用熔融挤出加工的方法制备了聚醚酰胺永久型抗静电剂。重点研究了不同含量的高氯酸锂(LiClO_4)对TPAE性能的影响,采用高阻计、扫描电镜、红外光谱对抗静电剂的表面电阻率、淬断面结构、化学结构进行了表征,并对其拉伸性能和耐漂洗性等进行了研究。结果表明,LiClO_4的质量分数为6%时,其在TPAE中分布均匀,抗静电效果较好,表面电阻率可以达到2×10~7Ω/sq,断裂伸长率在600%以上,而且抗静电性不会因为漂洗而失去,抗静电效果持久,是一种性能优异的永久型抗静电剂。The polyether-amide permanent antistatic agent was prepared by melt extrusion process by adding different kinds of alkali metal sodium salts and lithium salts with self-made long carbon chain polyether-amide elastomer(TPAE)as matrix.The influence of different contents of lithium perchlorate(LiClO4)on the performance of TPAE was mainly studied.The surface resistivity,quenching section structure and chemical structure of the antistatic agent were characterized by high resistance meter,scanning electron microscope and infrared spectroscopy.The tensile properties and washing resistance of the antistatic agent were also studied.The results show that when the mass fraction of LiClO4 is 6%,it is evenly distributed in TPAE,and the antistatic effect is better.The surface resistivity can reach 2×107Ω/sq,the elongation at break is above 600%,the antistatic property is not lost due to rinsing,and the antistatic effect is long-lasting.It is a permanent antistatic agent with excellent performance.
