Embodiment 1
[0018] Example 1: Take 91 parts of No. 25 transformer oil, 5 parts of oil-soluble gas-phase corrosion inhibitor, 2 parts of co-solvent, 0.5 part of defoamer, 1 part of antioxidant, 0.5 part of anti-fungal agent, and make the oil-soluble gas-phase corrosion inhibitor When the agent is lower than 120°C, add co-solvent and a small amount of No. 25 transformer oil, heat and melt, and when the oil-soluble vapor phase corrosion inhibitor is completely melted, slowly add it to the reaction kettle, stirring while adding, Then add antifungal agent, defoamer and antioxidant in turn, and keep stirring in a reaction kettle at 90°C for 2 hours to make gas-phase antirust oil.
Embodiment 2
[0019] Example 2: Take 86 parts of No. 25 transformer oil, 10 parts of oil-soluble gas-phase corrosion inhibitor, 2 parts of cosolvent, 0.5 part of defoamer, 1 part of antioxidant, 0.5 part of mold inhibitor, and the preparation method is the same as that of Example 1 .
Embodiment 3
[0020] Example 3: Take 81 parts of No. 25 transformer oil, 15 parts of oil-soluble vapor phase corrosion inhibitor, 2 parts of cosolvent, 0.5 part of defoamer, 1 part of antioxidant, and 0.5 part of antifungal agent. The preparation method is the same as in Example 1 .
[0021] The technical indicators of the vapor phase antirust oil of the above-mentioned embodiments are shown in Table 1.

Abstract
The invention discloses a multifunctional gaseous phase anti-rust oil which mainly comprises No. 25 transformer oil, oil-soluble vapor phase corrosion inhibitor, cosolvent dibutyl phthalate, defoamingagent polydimethylsiloxane, antioxidant zinc dialkyl dithiophosphate, mildewproof agent di-n-octyl-4-isothiazolin-3-ketone and the like; wherein the oil-soluble vapor phase corrosion inhibitor is prepared by mixing 10-40% of octadecyl butanedioic acid, 10-30% of 2-ethylamino heptadecenyl imidazoline, 2-20% of lanolin, 5-20% of zinc naphthenate and 15-30% of chromic acid tert-butyl ester. The gaseous phase anti-rust oil not only has the contact anti-rust property of the anti-rust oil, but also has the superior vapor phase anti-rust performance of the vapor phase corrosion inhibitor. The multifunctional gaseous phase anti-rust oil can be widely applied to long-term rust protection of military hardware and metal materials for civil use, more particularly, used for rust prevention of engines,large compressors, special gear boxes and the like, and mainly applicable to preventing a closed cavity system from rusting. The anti-rust oil not only can prevent black metal steel-made parts from rusting, but also has the function of rust prevention for multiple non-ferrous metal parts, thus effectively preventing metals such as steel, copper, zincification, chrome-plate and the like as well asalloy materials thereof from being corroded.
Description
technical field [0001] The invention relates to a gas-phase antirust oil, which belongs to the technical field of metal antirust. Background technique [0002] The problem of metal corrosion pervades all walks of life in the national economy. Metal corrosion will greatly damage the performance and commodity value of metal products, and even cause major failures and make equipment scrapped. 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. Based on the calculation of my country's GDP of 18.23 trillion yuan in 2005, the annual loss caused by corrosion in my country is at least More than 36 billion yuan, the harm is astonishing. In order to avoid corrosion, people have adopted a variety of techniques and methods to prevent the occurrence of metal corrosion. Among them, using anti-rust oil to protect metal products is one of the most common protection methods at prese...
