Abstract
The invention provides a water-based antirust corrosion inhibitor, and belongs to the technical field of corrosion inhibitors. Sodium tungstate, sodium fatty alcohol polyoxyethylene ether carboxylate and water-soluble imidazoline are used as main components, and the main components, sodium tripolyphosphate, calcium nitrate, sodium dodecyl sulfate, benzotriazole, sodium tetraborate, triethanolamine and other components form a water-based composition. Wherein sodium tungstate reacts with the metal surface to generate sodium tungstate precipitates to prevent metal oxidation and corrosion, and the electrochemical corrosion rate of iron can also be reduced. Sodium fatty alcohol polyoxyethylene ether carboxylate forms stable micelles, so that the antirust and corrosion inhibition effects are effectively realized. Triethanolamine can react with oxide or hydroxide on the surface of metal to generate a complex, so that the metal is prevented from being further oxidized. The antirust effect can be remarkably improved, and the rusting rate of the metal surface can be delayed. Moreover, the antirust corrosion inhibitor has good film-forming property, has excellent adhesiveness on the metal surface, and can play a long-acting antirust corrosion inhibition role.
