摘要（英）：

The invention provides a water-based coating for a stainless steel storage tank, and a preparation method thereof, and relating to the technical field of coatings. The water-based coating for the stainless steel storage tank comprises, by weight, 20 parts of potassium silicate, 9 parts of a styrene-acrylic emulsion, 9 parts of zinc powder, 8 parts of talcum powder, 21 parts of heavy calcium carbonate, 11 parts of rutile titanium dioxide, 0.1 part of KOH, 10 parts of hollow glass beads, 9 parts of silicon nitride, 5 parts of 3-mercaptopropyltrimethoxysilane, 0.2 part of a polyurethane thickener PUR2150, 0.9 part of a water repellent BS1360, 0.23 part of a 8034 defoamer, 0.6 part of a coupling agent, 0.4 part of a hindered amine photostabilizer, 0.7 part of a heat stabilizer, 0.7 part of anantioxidant and 20 parts of water. The preparation method includes the following steps: weighing above raw materials, grinding the raw materials, and mixing and stirring the ground raw materials. Thewater-based coating for the stainless steel storage tank has the advantages of strong color fastness, good adhesion and good corrosion resistance.
