Ethylene-acrylate salt ionomer antistatic agent was prepared with ethylene-ethyl acrylate copolymer and potassium hydroxide as the primary raw materials and blended with polypropylene (PP) to make self-made ionomer/PP antistatic alloy. Commercial Entira and PP were blended in the same way to prepare Entira/PP antistatic alloy. Then, the morphological and physical properties of the self-made ionomer/PP and Entira/PP were studied using differential scanning calorimetry, thermo-gravimetric analysis, rotary rheometer, and scanning electron microscope. The experimental results showed the development of a self-made ionomer in a torque rheometer successfully, and its performance in all aspects was similar to the commercial Entira. Material test results have shown that the physical properties such as surface and volume resistivity, antistatic durability, thermal weight loss, crystallization properties, and rheological properties of PP modified by self-made ionomer are very similar to those modified by Entira. And due to the selection of raw materials, this self-made ionic antistatic agent is cheaper than commercial Entira and has good research value.

Graphical abstract

A permanent antistatic agent was prepared by the saponification reaction of ethylene-ethyl acrylate copolymer and KOH. This antistatic agent can reduce the resistivity of PP by 8 orders of magnitude, showing an antistatic effect similar to that of commercial Entira.

乙烯丙烯酸酯盐离聚物/聚丙烯抗静电合金的制备与性能

以乙烯-丙烯酸乙酯共聚物和氢氧化钾为主要原料，制备了丙烯酸乙烯酯盐离聚物抗静电剂，并与聚丙烯（PP）共混，制备了自制的离聚物/ PP抗静电合金。将商业化的Entira和PP以相同的方式混合以制备Entira / PP抗静电合金。然后，使用差示扫描量热法，热重分析，旋转流变仪和扫描电子显微镜研究了自制的离聚物/ PP和Entira / PP的形态和物理性能。实验结果表明，在扭矩流变仪中成功开发了一种自制离聚物，其各个方面的性能均与商业化的Entira相似。材料测试结果表明，物理性能，例如表面和体积电阻率，抗静电耐久性，自制离聚物改性的PP的热失重，结晶性能和流变性能与Entira改性的PP非常相似。而且由于选择了原料，因此这种自制的离子型抗静电剂比商业化的Entira便宜，并且具有良好的研究价值。
