Abstract
The invention relates to the technical field of rust removal for industrial steel, and discloses an environmentally friendly rust remover and a preparation method thereof. The environmentally friendly rust remover comprises the following raw materials by weight percentage: 10-20% of phosphoric acid, 5-10% of citric acid, 5-15% of gluconic acid, 1-10% of pickling corrosion inhibitor, 1-10% of thickening agent, 0.1-0.5% of nonionic surfactant and balance of deionized water. According to the invention, rust removal and rust resistance can be carried out simultaneously, no pollution is generated, and oil stain on the surface of the metal can be better removed. The environmentally friendly rust remover and the preparation method have the advantages that the preparation method is not restricted by the equipment facility condition, the construction is simple, the labor intensity is mitigated, the work efficiency is increased, and the cost is reduced.
