Problems solved by technology

[0003] Most of the gas-phase anti-rust oils on the market contain gas-phase anti-rust agents with strong pungent odors such as dicyclohexylamine, cyclohexylamine, and tributylamine. Long-term intake will lead to a decline in human health, and even cause disease, which can cause great harm to the human body
Moreover, the film formation of gas phase antirust oil on the market is not uniform enough, and the gas phase performance is insufficient, which leads to poor or poor antirust performance.

Abstract

The invention discloses gas-phase antirust oil and a preparation method thereof. The gas-phase antirust oil is comprises the following components in parts by weight: 7-15 parts of an antirust agent, 3-5 parts of fatty acid, 4-10 parts of a film-forming agent, 6-12 parts of an amine-free gas-phase antirust agent and 70-80 parts of solvent oil. According to the invention, the amine-free gas-phase antirust agent is used for replacing a gas-phase antirust agent with strong pungent smell, so volatilization of irritant gas can be avoided, and the antirust performance of the gas-phase antirust oil ismore stable; meanwhile, under the synergistic cooperation of all the components provided by the invention, the gas-phase antirust oil has the advantages of being thin in oil film, good in film forming performance, high in antirust performance stability and the like can be obtained; and the gas-phase antirust oil can protect metal products in a contact or non-contact mode, does not need complex brush coating, is more convenient to operate, and can exert an effective antirust effect on parts with complex structures.

Description

technical field [0001] The invention belongs to the technical field of metal protection, and in particular relates to a gas phase antirust oil and a preparation method thereof. Background technique [0002] Corrosion is regarded as the "ultimate destroyer", and it costs $400 billion or more every year, far exceeding the sum of other natural disasters. Due to the complex pipeline and internal structure of large equipment, it is impossible to fully soak or spray anti-rust oil, so it is difficult to completely prevent large-scale equipment from rust by soaking or spraying anti-rust oil. The vapor phase anti-rust oil can achieve a good anti-rust effect through the dual performance of contact and non-contact with it. Therefore, large-scale equipment is generally treated with a gas-phase anti-rust oil. [0003] Most of the gas-phase anti-rust oils on the market contain gas-phase anti-rust agents with strong pungent odors such as dicyclohexylamine, cyclohexylamine, and tributylami...
