Problems solved by technology

Among them, when the workpiece is coated with thick oil film type antirust oil, it is easy to increase the amount of antirust oil and pollute the environment due to dripping; when the workpiece is coated with thin oil film type antirust oil, the oil film is relatively thin, resulting in poor antirust effect and oil film It is easy to adhere to dust in the air and cause rust problems; moreover, the existing thin oil film type anti-rust oil has a short anti-rust period and cannot be used for a long period of anti-rust

Abstract

The invention discloses a preparation method of multifunctional antirust oil and multifunctional antirust oil. The preparation method of the multifunctional antirust oil comprises the following steps:S10, providing base oil, mineral oil, a film forming agent, an oil solvent, a rust inhibitor A and a rust inhibitor B, dissolving the rust inhibitor A and the film forming agent in mineral oil to prepare a mixture; S20, dispersing the oil solvent, the rust inhibitor B and the base oil in the mixture to prepare the multifunctional antirust oil, wherein the rust inhibitor A is any one or a mixtureof at least two of barium petroleum sulfonate, calcium petroleum sulfonate, sodium petroleum sulfonate and barium dinonylnaphthalenesulfonate, and the rust inhibitor B is any one or a mixture of at least two of dodecenylsuccinic acid, dodecenylsuccinate, antirust agent T-703 and zinc naphthenate. The raw materials are added in a specific adding sequence, the rust inhibitor A and the rust inhibitorB are added in two steps, and the multifunctional antirust oil with suitable viscosity, oil film thickness, rust resistance, anti-corrosion property, separation stability and water replacement property is prepared.

Description

technical field [0001] The invention relates to the technical field of antirust new materials, in particular to a preparation method of a multifunctional antirust oil and the multifunctional antirust oil prepared by the method. Background technique [0002] Metal corrosion has been a problem that has plagued people for a long time. The loss caused by metal corrosion is extremely heavy. According to the statistics of the American Institute of Metals, the annual economic loss caused by metal corrosion in the world accounts for 4% of the total production value, and the scrap metal due to corrosion accounts for 4% of the total output. 30% of my country's annual economic losses due to metal corrosion amounted to more than 300 billion yuan. In order to avoid corrosion and reduce losses, people have adopted various protection methods, among which, using various anti-rust oils to protect metal workpieces is one of the most common protection methods at present. [0003] From the coat...
