The invention discloses long-acting antirust oil and a preparation method thereof. The long-acting antirust oil comprises the following components in parts by weight: 60-70 parts of base oil, 3-8 parts of petroleum barium sulfonate, 0.5-1 part of dodecenylsuccinic acid, 0.2-1 part of sorbitan monooleate, 2-6 parts of wool fat, 0.2-0.8 part of tert-butyl p-cresol, 0.5-1 part of benzotriazole, 0.5-1 part of stearic acid and 0.5-1 part of industrial lecithin. The preparation method comprises the steps of adding the base oil into a container, heating and then adding the petroleum barium sulfonate and the benzotriazole into the container; continuously heating and stirring to enable machine oil to be completely dehydrated; cooling and then adding the dodecenylsuccinic acid and the wool fat; stirring, dissolving and then continuously cooling; adding the rest components, and evenly stirring and mixing; filtering impurities to obtain the long-acting antirust oil. After a metal plate is treated by the long-acting antirust oil, a performance test is carried out on the metal plate, and the result proves that the long-acting antirust oil disclosed by the invention has the protection function for a long time.
