蒙皮材料防静电性能探索研究

Study on the Antistatic Property of Envelop Materials

通过在聚氨酯中添加导电云母、导电氧化锌、导电针状二氧化钛、多臂碳纳米管,制备了表面电阻率低至-6.1×10^6Ω的聚氨酯材料。将其涂覆于蒙皮材料后,当聚氨酯与蒙皮材料的质量比为1:1时,蒙皮材料的表面电阻率低至-8.5×10^6Ω,实现了蒙皮材料的防静电性能。同时,蒙皮材料的面密度由-140 g/m^2增加至-240 g/m^2。

The surface resistivity was reduced to-6.1×10^6Ω by adding conductive mica,zinc oxide,needle-like titanium dioxide and multi-arm carbon nanotubes in polyurethane material.When the mass ratio of the polyurethane to envelop material was 1:1,the surface resistivity of the envelop material was as low as^8.5×10^6Ω,which realized the antistatic performance of the envelop material.At the same time,the surface density of the envelop material increased from^140 g/m^2 to^240 g/m^2.
