Preparation method of dehydrated anti-rust 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...
