Abstract

The invention relates to a waterborne epoxy static-conducting oil-resistant anticorrosive paint and a preparation method thereof. The paint is composed of a component A and a component B, the component A is prepared from the following components in parts by mass: 50 to 80 parts of water-based nano-silver modified epoxy emulsion, 10 to 20 parts of water-based cosolvent, 2 to 5 parts of water-based elastic carbon nanotube composite conductive mica powder, 1.5 to 5 parts of water-based dispersing agent, 0.4 to 1.2 parts of water-based defoaming agent, 20 to 35 parts of water-based antirust pigment and filler, 0.2 to 0.5 part of water-based thixotropic agent and 10 to 15 parts of deionized water; the component B is a water-based epoxy curing agent and comprises the following components in parts by mass: 50-80 parts of a water-based modified amine curing agent and 2-5 parts of a water-based adhesion promoter; the component A and the component B are uniformly mixed according to the mass ratio of (5-10): 1; the preparation method of the coating comprises the following steps: respectively preparing the component A and the component B, and uniformly mixing the two components according to the ratio. The coating has the characteristics of stable conductivity of an intrinsic conductive coating and excellent conductivity of a doped conductive coating, and the flexibility and corrosion resistance of a paint film on a metal surface and the conductivity of the paint film are improved.

Description

technical field

[0001] The invention belongs to the technical field of anti-corrosion coatings, in particular the invention relates to a water-based epoxy antistatic anti-static oil-resistant anti-corrosion coating for the inner wall of an oil tank and a preparation method thereof. Background technique

[0002] In recent years, water-based coatings have been gradually promoted and applied in the petrochemical field, and water-based coatings have been included in the category of heavy-duty anti-corrosion coatings in relevant petrochemical standards.

[0003] At present, petrochemical coatings are mainly oil-based and heavy-duty anti-corrosion. Under the current stringent environmental protection policy requirements, my country is in the transition stage of "oil to water". The water-based technology of conductive static anti-corrosion coatings on the inner wall of petroleum storage tanks is in its infancy. It will replace traditional solvent-based static conductive anti-corros...
