The aqueous anti-corrosion and cooling multifunctional coating comprises an aqueous anti-corrosion base layer coating, an aqueous heat insulation intermediate layer coating and an aqueous cooling surface layer coating, wherein the aqueous anti-corrosion base layer coating is prepared by taking an polyacrylic emulsion as a film forming base material, iron-titanium powder as an anti-rust pigment and filler, calcium carbonate powder, precipitated barium sulfate powder and talcum powder as body fillers and accessory ingredients and water as auxiliary materials; the aqueous heat insulation intermediate layer coating is prepared by taking the polyacrylic emulsion as the film forming base material, hollow glass micro-beads as heat insulation fillers and the accessory ingredients and the water as the auxiliary materials; and the aqueous cooling surface layer coating is prepared by taking the polyacrylic emulsion as the film forming base material, titanium dioxide, talcum powder, hollow glass micro-beads and far-infrared ceramic powder as the cooling pigments and the fillers and the accessory ingredients and the water as the auxiliary materials. The aqueous anti-corrosion and cooling multifunctional coating disclosed by the invention can perform corrosion prevention and cooling on the storage tanks and the tank cars for oil, gas and chemical raw materials, and has the advantages of anti-corrosion property, effects of saving oil and gas, saving electrical energy and saving water resources, and environment-friendly property.

Description

technical field [0001] The invention relates to an anticorrosion coating for oil gas, chemical raw material storage tanks and tank cars and a preparation method thereof. Background technique [0002] During the storage and transportation of oil and gas in the open environment, when exposed to sunlight, the surface and internal temperature will rise rapidly, and most of the heat will be concentrated on the surface of the oil interface, which will accelerate the evaporation of oil and cause "big breathing loss" and "small breathing loss". These two losses exist throughout the year. According to statistics, when the average oil temperature is 10°C, the daily "small breathing" loss of the vaulted gasoline tank alone can reach 197 kg. [0003] As the driving force of oil and gas evaporation loss, the saturated vapor pressure of oil and gas increases rapidly in logarithmic relationship with the increase of absolute temperature of oil. Therefore, under the sun exposure in summer...
