Abstract

The invention discloses an electrostatic conductive coating, and belongs to the field of coatings. The electrostatic conductive coating comprises the following components by weight: 25-85% of high-molecular resin, 0.1-60% of an electrostatic conductive filling material, 1-60% of a solvent, and 10-50% of a curing agent; the electrostatic conductive filling material comprises at least one kind of material, which is selected from metal fibers including copper, aluminium, zinc, iron, silver, lead, titanium and magnesium. The metal fiber forms a conductive network, which is used for improving electrostatic conduction performance of the electrostatic conductive coating, and the conductive network can be used as reinforcement for enhancing strength of the electrostatic conductive coating, so that strength, toughness, compactness and wear resistance of the electrostatic conductive coating are improved. Cooperative complex formulation between components for preparing the electrostatic conductive coating is effected, so that an electrostatic conductive anticorrosion coating with high strength and high toughness is formed by the electrostatic conductive coating which is provided by the embodiment.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to an electrostatic conductive coating. Background technique [0002] Liquid petroleum products stored in petroleum storage tanks, especially light oils such as gasoline, diesel, kerosene, etc., are insulating media, and their resistivity is more than 10 13 Ω·m. During the transportation process, a large amount of static charge often accumulates due to friction caused by flowing, mixing, stirring, filling or extraction. When the accumulated electrostatic discharge energy is within the explosive limit range of the fuel vapor and air mixture, electrostatic fire or explosion may occur at any time. Therefore, the Chinese National Standard GB13348-1992 (Static Safety Regulations for Liquid Petroleum Products) stipulates that the anti-corrosion coating of petroleum storage tanks must have good electrostatic conductivity. At the same time, Appendix D of the Chinese National Standard GB6950-2001 (Safety...
