Abstract

Antistatic plasticizer can significantly enhance the antistatic properties of polyvinyl chloride (PVC), mitigating the potential hazards associated with static electricity (such as damage to electronic components, fire, explosion, etc.). However, the poor water resistance of the plasticizer dibutoxyethoxyethyl adipate (DBEEA) will limit the application performance of materials. In this work, powdered nitrile rubber (PNBR) was ingeniously used to improve the water extraction resistance of DBEEA in PVC. With 30 wt% PNBR added in plasticized PVC, the mass loss rate can reduce 4.96 wt% than plasticized PVC film. Meanwhile, the volume and surface resistivities of PVC/PNBR exposed to air are in the order of 10⁶ Ω·m and 10⁹ Ω, which meets the antistatic requirements of the relevant fields (such as electronics, healthcare, and chemical industry). After water immersion, both the volume and surface resistivity of PVC containing 30 wt% PNBR remain 10⁷ and 10¹¹ Ω, respectively. Furthermore, PVC/PNBR exhibits excellent low-temperature resistance (−28 °C), thermal stability and elasticity, which will broaden the application areas of antistatic plasticized PVC.

Highlights

The plasticized PVC/PNBR with antistatic property is prepared.
PNBR has good adsorption to DBEEA.
PVC/PNBR exhibits superior low-temperature resistance and thermal stability.

丁腈橡胶改性制备抗静电耐水浸聚氯乙烯的新工艺

抗静电增塑剂可以显著提高聚氯乙烯（PVC）的抗静电性能，减轻静电带来的潜在危害（如损坏电子元件、火灾、爆炸等）。但增塑剂己二酸二丁氧乙氧基乙酯（DBEEA）耐水性差，限制了材料的应用性能。本研究巧妙地将粉末丁腈橡胶（PNBR）用于提高聚氯乙烯中DBEEA的抗水浸性能。增塑PVC膜中添加30%的PNBR，质量损失率比增塑PVC膜降低4.96 wt%。同时，PVC/PNBR在空气中的体积电阻率和表面电阻率分别为106 Ω·m和109 Ω，满足相关领域（如电子、医疗、化工等）的抗静电要求。经水浸泡后，含30% PNBR的PVC体积和表面电阻率分别为107和1011 Ω。此外，PVC/PNBR具有优异的耐低温性（- 28℃）、热稳定性和弹性，这将拓宽抗静电增塑型PVC的应用领域。制备了具有抗静电性能的增塑型PVC/PNBR。PNBR对DBEEA具有良好的吸附性能。PVC/PNBR具有优异的耐低温性和热稳定性。
