摘要

考察了颜填料体积浓度（PVC）对水性环氧导静电防腐蚀涂料涂层导静电性能和防腐蚀性能的影响，运用X射线能谱（EDX）分析了导电填料的元素组成，采用电化学阻抗谱（EIS）、扫描电镜（SEM）等手段对不同颜填料体积浓度的涂层进行了性能测试及表征，根据不同颜填料体积浓度涂层的物理机械性能、盐水浸泡实验结果和电化学阻抗谱分析，确定该水性环氧导静电防腐蚀涂料的最佳颜填料体积浓度为35%。

Abstract

The effect of pigment volume concentration (PVC) on the antistatic and anticorrosive properties of waterborne antistaticanticorrosive epoxy coatings was studiedThe element components of conductive pigments were analyzed by X-ray energy dispersive spectrometer (EDX)

and the protective properties and morphology of coatings with different PVCs were characterized by electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM) respectivelyThe optimal PVC of this waterborne antistatic anticorrosive epoxy coating was determined as 35% based on the results of the tests of mechanical

physical and corrosionresisting performance

and the analysis of EISThe results showed that the corrosionresisting performance of coatings improved at first with increasing PVC and then decreased after PVC exceeded 35% in the range of PVC from 25% to 45%.
