Gas-phase rust preventive oil and preparation method thereof

Abstract

Gas-phase rust preventive oil comprises the following components: 12-19 parts of an acid soap complex agent, 4-8 parts of a rust preventive 1, 6-10 parts of a rust preventive 2, 5-7 parts of an improver, and 60-70 parts of a complex solubilizer. The invention further discloses a preparation method of the gas-phase rust preventive oil. Aiming at the condition that complete rust preventive oil cannot be produced a large-scale closed storage tank, a dedicated gas-phase rust preventive oil is developed, and the gas-phase rust preventive oil can not only form a good rust preventive protection layer on the metal surface, but also diffuses VCI gas-phase rust preventive gas at the same time.

Description

technical field [0001] The invention relates to an antirust oil and a preparation method thereof, in particular to a gas phase antirust oil and a preparation method thereof. Background technique [0002] Corrosion is one of the main forms of damage to fasteners, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national economy. There are many ways to prevent metal corrosion, the most commonly used method is to cover the metal surface with various anti-corrosion protective layers, or add corrosion inhibitors to the liquid or gaseous anti-corrosion medium to form a protective film on the metal surface to isolate the metal surface. Contact of surfaces with corrosive substances. [0003] In order to avoid corrosion and reduce losses, people have adopted various methods, such as using antiru...

Problems solved by technology

However, the anti-rust oil with a long anti-rust period will easily produce a thicker oil film after the parts are oiled, which is easy to stick to hands; the anti-rust oil with a thin oil film has a short anti-rust period, and the damp heat and salt spray tests are not ideal.

[0005] Traditional anti-rust oil is to form a protective layer on the metal surface to block water vapor, but for large-scale equipment with complex structures, for such large-scale equipment that cannot be soaked to achieve 100% full coating of anti-rust oil, or large airtight storage barrels, or The sealed storage tank equipment that can only spray oil through tiny filling holes, and the new gas-phase anti-rust oil with the dual effects of surface covering, water-proof, gas-phase and gas-phase anti-rust are born.

Such workpiece operations are likely to cause incomplete oil film, resulting in poor anti-rust results

[0006] Traditional vapor phase anti-rust oils are all added with dicyclohexylamine, which emits strong amine gas to produce anti-rust and anti-oxidation effects on metals, but dicyclohexylamine is strongly irritating to the eyes, skin and respiratory tract, and is quite harmful to the human body. Large, direct contact with eyes may cause permanent visual damage, and long-term repeated low-concentration skin contact may also cause dermatitis and other problems. Therefore, in EU countries with strong environmental awareness, dicyclohexylamine is considered unaffected. welcome chemicals
