To ensure the use of oil tank safely, it is necessary that the conductive coating was used in inner oil tank. This paper concentrates on a study of the electrical properties (surface resistance rate) of epoxy resins filled with different types of carbon pigments, such as colloid graphite, carbon black and mixture of colloid graphite/carbon black, as well as on the investigation of some mechanical properties, appearance and morphology .To produce a light grey and conductive coating, titanium oxide and carbon electro-conductive pigments were investigated in this article. The objective of the experiment therefore was to choose the optimal electro-conductive filler and determine the optimal mix ratio of colloid graphite/ carbon black and titanium oxide /colloid graphite and titanium oxide /mixable electro-conductive filler. From the experiment analysis, it was found that the optimized colloid graphite and carbon black mix ratio is 3:1; the optimized titanium oxide and colloid graphite mix ratio is 1:1; the optimized titanium oxide and mixable electro-conductive filler mix ratio is 8:1. In terms of resistance rate and color, we may arrive at the conclusion that 15μm colloid graphite as the optimized electro- conductive pigments and the optimal mix ratio of titanium oxide /colloid graphite is 1:1.
