Weathering resistant steel surface rust layer stabilizing treatment agent for industrial atmospheric environment

The invention provides a weathering resistant steel surface rust layer stabilizing treatment agent for an industrial atmospheric environment. The weathering resistant steel surface rust layer stabilizing treatment agent is prepared from the following chemical components in percentage by mass: 25 to 45 percent of acrylic resin, 2.0 to 6.0 percent of chromium sulfate, 3.0 to 8.0 percent of ferric oxide, 2.0 to 6.0 percent of ferroferric oxide, 0.5 to 3.5 percent of copper sulfate, 0.3 to 1.5 percent of sodium hydrogen sulfite, 1.0 to 6.0 percent of sodium molybdate, 0.5 to 3.5 percent of nickel sulfate, 2.0 to 5.0 percent of potassium phosphate, 0.05 to 0.5 percent of surfactant, 0.05 to 0.5 percent of defoaming agent, 0.05 to 0.5 percent of dispersing agent, 0.05 to 0.5 percent of thickening agent and the balance of water. Wherein the adding amount of the plasticizer is 2-5% of that of the resin. The stabilizing treatment agent is used for treating the surface of the weathering resistant steel before the weath
