Embodiment 1

[0027] A water displacement type film antirust oil, its raw material composition and weight are respectively (taking 1000g water displacement type film antirust oil as an example):

[0028]

[0029] The preparation steps of above-mentioned water replacement type film antirust oil are as follows:

[0030] ⑴Put engine oil, calcium petroleum sulfonate, octadecylamine N-oleoyl sarcosine, and dodecenylsuccinic acid into the reactor, heat and stir the reactor, and control the temperature at 110°C-120°C , heated for about 30 minutes to completely dissolve the raw materials in the reactor and stir evenly;

[0031] (2) Cool the temperature of the material to about 60°C, add laurane and high-efficiency displacer, and stir for about 30 minutes until the mixture is uniform, and then the water-displacement type film anti-rust oil can be obtained, and the temperature of the reactor should be kept constant during the reaction.

[0032] Preferably, the engine oil is one or more mixtures o...

Embodiment 2

[0040] A water-displacing thin-film anti-rust oil, its raw material components and parts by weight are:

[0041]

[0042] The preparation method of the above-mentioned water-displacing type film antirust oil, the steps are as follows:

[0043] ⑴Put engine oil, calcium petroleum sulfonate, octadecylamine N-oleoyl sarcosine, and dodecenylsuccinic acid into the reactor, heat and stir the reactor, and control the temperature at 110°C-120°C , heated for 30 minutes to completely dissolve the raw materials in the reactor and stir evenly;

[0044] (2) Cool the temperature of the material to 60°C, add laurane and displacing agent, stir for 30 minutes until the mixture is uniform, and then the water displacement type film antirust oil can be obtained, and the temperature of the reactor should be kept constant during the reaction.

[0045] Preferably, the engine oil is one or more mixtures of 15# engine oil, 32# engine oil, 46# engine oil, and 68# engine oil;

[0046] Preferably, th...

Abstract

The invention discloses water displacement type thin-film antirust oil. The antirust oil is prepared from the following raw materials in parts by weight: 5-10 parts of engine oil, 75-85 parts of laurane, 1-3 parts of petroleum sulfonate; 2-6 parts of octadecylamine N-oleoyl sarcosinate, 2-4 parts of dodecencylsuccinic acid and 2-4 parts of an efficient displacer. The antirust oil has the characteristics of light odor, thin film, high dehydration property and long antirust period, and is non-flammable. Tests for items such as salt spray, damp heat, water displaceability, film thickness and thelike of the antirust oil show that the antirust oil has the characteristics of excellent antirust performance, efficient water displaceability and thin film, is safe and environmentally and has excellent application prospect.

Description

technical field [0001] The invention belongs to the technical field of antirust oil, in particular to a water-displacing thin film antirust oil and a preparation method thereof. Background technique [0002] Metals (including ferrous metals and non-ferrous metals) still occupy the dominant position of modern engineering materials due to their excellent performance and processability, and are widely used in petroleum machinery, automobile manufacturing, aerospace, transportation and other industries. However, metals Parts and equipment will corrode due to various factors during processing, storage, transportation and use. On June 1, 2016, the report of the "Research on Corrosion Situation and Control Strategy in my country" held at the Beijing Convention Center indicated that the total cost of corrosion in my country in 2014, including the loss caused by corrosion and the investment in corrosion protection, accounted for about 3.34% of GDP in that year. , totaling more than 2...
