Abstract
The invention discloses a corrosion inhibitor for inhibiting seawater with the salinity of 25-40 percent. The corrosion inhibitor comprises the following components in percentage by weight: 26-38 parts of urotropin, 18-28 parts of sodium molybdate, 15-19 parts of phosphoric acid triethanolamine, 0.9-3.2 parts of thiosemicarbazide, 12-15 parts of calcium gluconate, 10-12 parts of rosin amine polyoxylethylene ether, 16-18 parts of mineral oil, 25-35 parts of benzotriazole, 12-15 parts of halogenated alkyl pyridine and 18-25 parts of octacosanol. The corrosion inhibitor can be firmly combined with carbon steel under the action of urotropin, sodium molybdate, rosin amine polyoxylethylene ether, halogenated alkyl pyridine and the mineral oil, so that the adsorption capacity of the corrosion inhibitor to a deck is greatly improved; the corrosion resistance of a metal surface can be enhanced; furthermore, the corrosion inhibitor is environment-friendly and has no toxic or side effect.
