Problems solved by technology

This type of corrosion inhibitor has obvious corrosion inhibition effect on ferrous metals, but is corrosive to brass and aluminum
In addition, the color of this kind of corrosion inhibitor is dark, because as the degree of oxidation of petroleum grease increases, the number of polar groups in it increases, resulting in darker color

Embodiment 1

[0015]

[0016] The preparation method is as follows: each component is mixed uniformly at room temperature according to the formula to obtain the product.

[0017] Oxidized petroleum grease has good corrosion inhibition effect. Because its molecules contain polar groups such as carboxyl groups and hydroxyl groups, it has strong adsorption capacity on metal surfaces and good oil solubility. The presence of hydroxyl groups can emulsify water on the metal surface.

Embodiment 2

[0019]

[0020]

[0021] The preparation method is the same as above.

[0022] The corrosion inhibitor of the invention has low price, less consumption, excellent corrosion inhibition effect, bright and transparent coating, clean and beautiful appearance and no influence on product quality, and can be used for rust prevention of materials such as steel, cast iron and copper alloy.

Embodiment 3

[0024]

[0025] The preparation method is the same as above.

[0026] The preparation method of the present invention has the advantages of simple process, mild reaction conditions, low production cost, and good product quality. The product is often used in turbine oil, added to internal combustion engine oil, instrument oil, gear oil and hydraulic oil, and is effective for metal in the oil. Play the role of corrosion inhibition and rust prevention.

Abstract

The invention provides a petroleum ester oxide barium soap corrosion inhibitor. The petroleum ester oxide barium soap corrosion inhibitor comprises petroleum ester oxide barium soap, caproic acid, calcium petroleum sulfonate, ethyl stearate, benzotriazol and gasoline. The corrosion inhibitor is prepared by uniformly mixing above components at room temperature according to a formula. Petroleum ester oxide has a good corrosion inhibition effect. The molecule of the petroleum ester oxide contains a carboxyl group, a hydroxyl group and other polar groups, so the petroleum ester oxide has very strong adsorption ability to the metal surface and also has good oil solubility; and the hydroxyl group can emulsify water on the metal surface.

Description

technical field [0001] The invention relates to a corrosion inhibitor, in particular to an oxidized petroleum grease barium soap corrosion inhibitor, which belongs to the technical field of chemical industry. Background technique [0002] In the past, in order to prevent metal corrosion and rust, people often applied animal and vegetable oils, mineral oils, lubricating oils, etc. directly on the metal surface. These oils are stable to metals and will not corrode metals. ability, but the ability to prevent the migration of H20 and 02 to the metal surface is limited. Some people have done experiments and found that when the metal surface is coated with a 5mm thick lubricating oil film, the water passing through the oil film after 5 days is 0.34-0.45g, while the water passing through the anti-rust oil film of the same thickness is only 0.005-0.008g. In addition, these greases cannot prevent the penetration of corrosive substances such as S02 and H2S. Grease itself will also p...
