Problems solved by technology

[0002] The existing anti-corrosion coatings for oil storage tanks mostly use static conductive coatings containing volatile organic solvents. The disadvantage of this type of coatings is that the volatilization of organic solvents in the storage tanks will cause safety hazards and endanger the health of construction workers. A small number of solvent-free coatings used for anti-corrosion on the bottom of storage tanks, but they are not conductive and have a strong smell

Abstract

The invention relates to a solvent-free electrostatic conducting anti-corrosive coating for oil tanks and the preparation method thereof. The solvent-free electrostatic conducting anti-corrosive coating comprises a solution A prepared from bisphenol A type liquid-state epoxy resin, epoxy-containing polyol ether, titanium dioxide, precipitated barium sulfate, talcum powder, acidic polyester and polyamide, fluorocarbon-modified siloxane, polyacrylate-modified fluorocarbon polymer, poly-carboxylate, light-colored conductive powder and alkanolamine solution of unsaturated acidic carboxylate, and a solution B prepared from polyamide resin, N,N-dimethyl benzyl amine and poly-carboxylate. When in use, the solution A and the solution are mixed and solidified to form a coating. The solvent-free electrostatic conducting anti-corrosive coating has constructability and storage stability similar to those of solvent electrostatic conducting coatings, and no discharge of volatile organic solvent in the production and the construction process. The coating has the advantages of good electrostatic conductivity, high chemical resistance and good oil resistance, and can be applied to steel surfaces of different parts in the oil tanks, such as bottom plates, inner walls, floating cabins, floating roofs and pillars, to prevent corrosion.

Description

technical field [0001] The invention relates to a solvent-free static conductive anti-corrosion coating for an oil storage tank and a manufacturing method thereof, which can be used for anti-corrosion of steel surfaces at the inner bottom plate, inner wall, floating tank, floating roof, tank inner column and the like of the oil storage tank. technical background [0002] The existing anti-corrosion coatings for oil storage tanks mostly use static conductive coatings containing volatile organic solvents. The disadvantage of this type of coatings is that the volatilization of organic solvents in the storage tanks will cause safety hazards and endanger the health of construction workers. A small number of solvent-free coatings used for anti-corrosion at the bottom of storage tanks are not conductive and have a strong smell. Contents of the invention [0003] The technical problem to be solved by the present invention is to avoid the deficiencies in the above-mentioned prior a...
