抗静电聚酯的制备与性能

Preparation and Properties of Antistatic Polyester

摘要: 本文采用共混的方式将常规PET切片与聚丙烯酸共混制备了亲水性聚酯，利用TG、DSC等手段测试了共混聚酯的热性能，发现其与常规聚酯相比，共混聚酯的热性能比较稳定，其中熔点有所降低，能在生产中降低一定的加工温度。在力学性能方面，共混聚酯的性能先升高后降低。通过对共混聚酯的抗静电性能表征上，发现共混聚酯的抗静电性能能够达到109 Ω•m，远高于常规PET材料。

Abstract: Hydrophilic polyester was prepared by blending conventional PET chips with polyacrylic acid. The thermal properties of the blended polyester were tested by means of TG and DSC. It was found that it was blended with conventional polyester. The thermal properties of the ester are relatively stable, and the melting point is lowered, which can lower the processing temperature in production. In terms of mechanical properties, the properties of the blended polyester first increase and then decrease. By characterizing the antistatic properties of the blended polyester, it was found that the antistatic properties of the blended polyester can reach 109 Ω•m, which is much higher than conventional PET materials.
