抗静电聚氯乙烯的制备与研究

Preparation and Research of Antistatic Polyvinyl Chloride

目的根据当代塑料包装和防静电包装的现状,综合分析了PVC的优缺点,研究了影响抗静电PVC的抗静电效果的相关因素,并为PVC的抗静电效果的进一步改善提供了参考。方法利用外部涂覆的方法制备抗静电PVC,分别测定抗静电PVC和一般PVC的相对摩擦系数、体积电阻率,并分析抗静电PVC的性能变化。结果综合分析抗静电剂对摩擦系数和表面电阻率的影响,确定系列抗静电剂发挥作用的最佳浓度为2.0%左右,环境条件为25℃左右,60%Rh左右。该发挥最佳作用的条件可以为之后抗静电剂在包装方面的应用提供相应的参考和应用。

Abstract： Objective According to current plastic packaging and the anti-static packaging, we analysed the property of PVC and studied relative factors of anti-static and gave some references about improving the anti-static effects. Method This was prepared using an external coating of antistatic PVC, then measured and the volume resistivity of antistatic PVC and ordinary PVC. Analyzed the performance changes antistaticPVC, we stated the best date which includes the best concenttration at 2.0%,ambient temperature at 25℃ and 60%RH.This can be used in anti-packaging as reference.
