Problems solved by technology

[0002] Various light petroleum product storage tanks in the prior art mostly use water spraying to cool down to prevent spraying to ensure safety and reduce heat loss, while the surface of light petroleum product storage tanks uses vacuum glass microbead heat insulation coatings that have been used for many years , the coating material has a short service life, serious pulverization, and mixed with falling dust to form a black coating, causing the tank body to "breathe", rust, lose the function of sun protection and heat insulation, and cannot effectively maintain the stable temperature of the oil in the storage tank. Increase the evaporation loss of oil / gas products, it is difficult to play an effective auxiliary effect of energy saving and emission reduction, increase the waste of water, electricity and gas, and greatly increase the operating costs of enterprises

Abstract

The invention discloses a multifunctional composite coating for an oil-gas storage tank and a preparation method thereof, and solves the technical problems to achieve the aims of prolonging the service life of a coating material, saving energy and reducing discharge. The composite coating is compounded by a bottom layer and a surface layer; and the preparation method comprises: manufacturing finished products of the bottom layer and the surface layer, diluting the finished product of the bottom layer by an X501 solvent, spraying the diluted finished product of the bottom layer on an anti-corrosion coating of the oil-gas storage tank, drying the anti-corrosion coating, diluting diisocyanate curing agent HDI dimmer or trimer by an X502 solvent, mixing the diluted HDI curing agent with the finished product of the bottom layer, and spraying the mixture onto a dry film of the bottom layer to prepare the composite coating consisting of the bottom layer and the surface layer. Compared with the prior art, the composite coating adopted cannot be heated by sunning, so the composite coating saves power consuming and water spraying equipment and water spraying and temperature reducing control processes, avoids waste of water and electric resources, and has guarantee functions of static conduction, fire resistance and safety; and by means of the fluorocarbon surface layer, the composite coating has strong protection, stain resistance and service life of more than ten years.
