Embodiment 1

[0027] Embodiment 1: 15 parts by weight of 5# white oil are put into the reaction kettle and heated to 110~120 ℃ while stirring for dehydration, the calcium petroleum sulfonate of 6 parts by weight, the lanolin magnesium soap of 4 parts by weight and 1 Dodecenylsuccinic acid in parts by weight is added into the reactor and continuously stirred to make it dissolve completely.

[0028] Add 0.5 parts by weight of benzotriazole into 7 parts by weight of absolute ethanol and dissolve at 50-60°C to obtain a dissolved substance, and add the dissolved substance when the temperature in the reactor drops below 50°C, and the Add 3 parts by weight of petroleum ether and 63.5 parts by weight of refined kerosene into the reactor and stir evenly. When the temperature in the reactor drops to room temperature, filter to prepare dehydrated antirust oil.

Embodiment 2

[0029] Embodiment 2: put the 5# white oil of 17 parts by weight into the reaction kettle and heat to 110~120 ℃ while stirring and carry out dehydration, the calcium petroleum sulfonate of 7 parts by weight, the lanolin magnesium soap of 3 parts by weight and 2 Dodecenylsuccinic acid in parts by weight is added into the reactor and continuously stirred to make it dissolve completely.

[0030] Add 0.6 parts by weight of benzotriazole into 8 parts by weight of absolute ethanol and dissolve at 50-60°C to obtain a dissolved substance, and add the dissolved substance when the temperature in the reactor drops below 50°C, and the Add 2 parts by weight of petroleum ether and 60.4 parts by weight of refined kerosene into the reactor and stir evenly. When the temperature in the reactor drops to room temperature, filter to prepare dehydrated antirust oil.

Embodiment 3

[0031] Embodiment 3: 16 parts by weight of 5# white oil are put into the reactor and heated to 110~120 DEG C while stirring for dehydration, 9 parts by weight of calcium petroleum sulfonate, 1 part by weight of lanolin magnesium soap and 2.5 parts by weight Dodecenylsuccinic acid in parts by weight is added into the reactor and continuously stirred to make it dissolve completely.

[0032] Add 0.6 parts by weight of benzotriazole into 6 parts by weight of absolute ethanol and dissolve at 50-60°C to obtain a dissolved substance, and add the dissolved substance when the temperature in the reactor drops below 50°C, and the Add 4 parts by weight of petroleum ether and 60.9 parts by weight of refined kerosene into the reactor and stir evenly. When the temperature in the reactor drops to room temperature, filter to prepare dehydrated antirust oil.

Abstract

The invention relates to a preparation method of dehydrated anti-rust oil. The preparation method comprises the following steps of: adding 10-20 parts by weight of white oil No 5 into a reaction kettle, heating to the temperature of 110-120 DEG C while stirring so as to dehydrate, adding 3-10 parts by weight of petroleum calcium sulfonate, 2-5 parts by weight of lanolin magnesium soap and 1-3 parts by weight of dodecenylsuccinic acid into the reaction kettle, and continuing stirring so as to completely dissolve petroleum calcium sulfonate and lanolin magnesium soap; and adding 0.5-1 part by weight of triazole into 5-10 parts by weight of absolute ethyl alcohol, dissolving triazole in absolute ethyl alcohol at the temperature of 50-60 DEG C to obtain solute, adding the solute into the reaction kettle when the reaction kettle is cooled to 50 DEG C or below, then adding 1-7 parts by weight of petroleum ether and 50-70 parts by weight of refined kerosene into the reaction kettle, stirring to be uniform, and filtering when the reaction kettle is cooled to room temperature, so that the dehydrated anti-rust oil is prepared. The dehydrated anti-rust oil prepared by adopting the preparation method provided by the invention contains no hazardous substances such as barium, aromatic hydrocarbon and sulphur, produces no irritating odour, does not cause emulsification or sediment precipitation after long-term use, has good rust resistance and is environment-friendly and safe.

Description

[0001] technical field [0002] The invention belongs to the technical field of anti-rust oil, and in particular relates to a configuration method of dehydrated anti-rust oil. [0003] Background technique [0004] The dehydrated anti-rust oils currently on the market usually use barium-containing corrosion inhibitors as anti-rust agents. Although these anti-rust agents have excellent anti-rust performance, they are easily scattered in nature during use and decompose into water-soluble and toxic The barium compounds are harmful to the human body and the environment. [0005] In addition, the base oil of dehydrated anti-rust oil usually uses machine oil and kerosene, which not only has a pungent smell, but also contains aromatic hydrocarbons, sulfur and other substances, which will cause damage to the human nervous system, liver and kidneys. [0006] With people's emphasis on environmental protection and the improvement of e...
