Abstract

The invention discloses a high-solid-content superhigh-corrosion-resistant water-based epoxy static conductive paint and a preparation method thereof. The high-solid-content superhigh-corrosion-resistant water-based epoxy static conductive paint comprises a component A and a component B, wherein the component A comprises deionized water, wetting dispersant, a foam inhibitor, a flash corrosion inhibitor, a water-based epoxy curing agent, a film-forming cosolvent, conductive mica powder, a corrosion inhibitor, a defoaming agent, a flatting agent and a thickening agent; and the component B comprises modified epoxy resin, a conductive additive, an anti-settling agent, an amphoteric dispersant, an amphoteric defoaming agent, a diluents and a filler. The high-solid-content superhigh-corrosion-resistant water-based epoxy static conductive paint is smooth and hard in paint film, high in compactness, excellent in physical and mechanical properties such as adhesive power, high in heat resistance and water resistance, superhigh in corrosion resistance, and stable in conductivity; the painting requirement can be met by forming a film at one step; the paint is low in cost and strong in market competitiveness; and the deionized water serves as a solvent, so the paint is non-toxic, harmless, safe and environment-friendly.

Description

technical field

[0001] The invention relates to a paint technology, in particular to a water-based epoxy electrostatic conductive paint with high solid content and super corrosion resistance and a preparation method thereof. Background technique

[0002] With the rapid development of my country's petrochemical industry, the production and use of petroleum products are increasing, and the corrosion and static electricity safety issues of petroleum storage tanks are increasingly concerned. The electrostatic hazard of the oil tank is mainly due to the increase of the static voltage in the oil tank due to the charged oil flow. If only a general insulating anti-corrosion layer is used in the oil tank, the static electricity in the oil tank cannot be discharged in time, and there is a hidden danger of the oil tank explosion. Therefore, the anticorrosion of oil tanks must not only have good corrosion resistance, but also have excellent static conductivity. It is the most direct, m...
