Embodiment 2

[0037] A solvent type thixotropic antirust oil is prepared from the following table 2 weight percent components:

[0038] The formula of the solvent type thixotropic antirust oil of table 2 embodiment 2

[0039]

[0040]

[0041] Add base oil with a viscosity of 25-30cSt at 40°C into the reaction kettle, and raise the temperature to 80°C. Start stirring at a stirring rate of 100 rpm, add calcium dinonylsulfonate, oxidized paraffin calcium soap, lanolin, and dodecenylsuccinic acid, stir for 20 minutes, and the oil in the reactor is clarified. Then add oil-soluble polyaniline and dioctyl sebacate, stir for 20 minutes, and the oil in the reaction kettle is clarified. Add hydrogenated castor oil and fumed silica, and stir for 10 minutes. Turn off the heating, lower the temperature to 40°C, and add dearomatized solvent oil.

Embodiment 3

[0043] A solvent type thixotropic antirust oil is formulated from the following table 3 weight percent components:

[0044] The formula of solvent-type thixotropic antirust oil of table 3 embodiment 3

[0045] raw material name

[0046] Add base oil with a viscosity of 30-35cSt at 40°C into the reaction kettle and raise the temperature to 80°C. Start stirring at a stirring rate of 100 rpm, add barium dinonylsulfonate, barium paraffin oxide soap, sulfonated lanolin calcium soap, and dodecenylsuccinic acid, stir for 20 minutes, and the oil in the reactor is clarified. Then add oil-soluble polyaniline and dioctyl sebacate, stir for 20 minutes, and the oil in the reaction kettle is clarified. Add modified hydrogenated castor oil and fumed silica, and stir for 10 minutes. Turn off the heating, lower the temperature to 40°C, and add dearomatized solvent oil.

Abstract

The invention relates to anti-rust oil for steel corrosion protection and a preparation method of anti-rust oil, in particular to solvent type thixotropic anti-rust oil and a preparation method thereof and belongs to the field of metal protection. The solvent type thixotropic anti-rust oil is prepared from components including, by weight, 5-30% of an anti-rust agent, 0.1-5% of a thixotropic agent, 0.1-5% of a film-forming agent, 0.1-3% of a coalescing agent, 5-20% of the base oil and the balance of dearomatization solvent oil. The thixotropic agent is combined with oil-soluble polyaniline, so that good salt fog resistance of the anti-rust oil is achieved, and time for salt fog can reach more than 400 hours.

Description

technical field [0001] The invention relates to an antirust oil for steel corrosion protection and a preparation method thereof, in particular to a solvent-type thixotropic antirust oil and a preparation method thereof, belonging to the field of metal protection. Background technique [0002] In the field of metal processing, metal workpieces corrode during production, storage and transportation, which not only causes huge economic losses, but also causes waste of resources. As China transforms from a manufacturing powerhouse to a manufacturing powerhouse, the quality requirements for metal workpieces are getting higher and higher. Anti-rust oil is widely used for metal protection, so the requirements for anti-rust oil are also getting higher and higher. [0003] Traditional antirust oil mainly relies on antirust additives, film formers such as paraffin or resin to provide its antirust performance.
