Abstract
The invention discloses an antirust oil for metal pipelines, which is prepared from the following raw materials in parts by weight: 16-20 parts of rare-earth antirust hydraulic oil, 60-80 parts of 20# machine oil, 1-3 parts of dimethyl chlorophthalate, 3-7 parts of asphalt, 1-2 parts of N,N-bis(2-cyanoethyl)formamide, 2-3 parts of polyoxyethylene stearate, 1-2 parts of sorbitan fatty acid ester, 1-3 parts of methyl benzotriazole, 0.5-1 part of zinc naphthenate, 0.1-3 parts of santobrite, 0.3-1 part of stannous sulfate and 0.4-1 part of thiosinamine. The rare-earth antirust hydraulic oil is added into the antirust oil. The alkyl ketone dispersion solution can improve the flowability and enhance the reaction activity. The added rare-earth ions can generate an insoluble complex with OH- generated in the oxygen-absorption corrosion process on the metal substrate surface, thereby decelerating the corrosive electrode reaction and having favorable slow-release effect.
