Abstract
The invention discloses a corrosion inhibitor for sulfur removal of a ship engine. The corrosion inhibitor comprises the following components in parts by weight: 28-38 parts of zinc carbonate, 25-32 parts of sodium molybdate, 24-28 parts of mannich base quaternary ammonium slat, 18-25 parts of propanol, 25-35 parts of benzyl chloride, 5-9 parts of adjacent dehydroabietic vanilla aldehyde amine schiff base, and 12-15 parts of stearamide. The prepared corrosion inhibitor can form excellent solubility together with diesel, and can achieve the effect of preventing corrosion as a good corrosion inhibitor of diesel.
