preparation example Construction

[0014] The present invention also provides a preparation method of anti-rust oil. The method is to put the base oil into the reaction kettle, then add the compound anti-rust agent, heat and stir until dehydration, and then filter to obtain the anti-rust oil, wherein the compound anti-rust agent The antirust agent is rare earth-β-diketone complex and barium petroleum sulfonate, sodium petroleum sulfonate, calcium petroleum sulfonate, barium dinonyl naphthalene sulfonate, barium heavy alkylbenzene sulfonate, non-barium type heavy alkyl A mixture of at least one of benzene sulfonate, magnesium lanolin soap, aluminum lanolin soap, aluminum stearate, barium oxide soap, and zinc naphthenate. During the mixing process of base oil and anti-rust agent in the reactor, polycondensation dehydration will be carried out, usually at 100°C-120°C, complete dehydration can be achieved, so as to achieve long-term anti-rust effect.

Embodiment 1

[0024] Put 90 grams of solvent gasoline into the reaction kettle, stir, heat up to 75°C, then add 4 grams of lanthanum acetylacetonate, 1 gram of barium petroleum sulfonate, heat and stir to 100°C for dehydration, cool to 60°C, add 2 grams of benzotri Azole, 3 grams of industrial lanolin is fully stirred, and then filtered through a 500-mesh filter to obtain anti-rust oil.

[0025] The tinplate is directly immersed in the antirust oil obtained above for 3 minutes, and the tinplate is continuously vibrated. Then take it out and let it dry naturally.

Embodiment 2

[0027] Put 85 grams of solvent gasoline into the reaction kettle, stir, heat up to 75°C, then add 5 grams of europium acetylacetonate, 5 grams of barium petroleum sulfonate, heat and stir to 120°C for dehydration, then cool to 60°C and add 2 grams of benzotri After nitrogen azoles, 3 grams of dodecenylsuccinic acid are fully stirred, and then filtered through a 600-mesh filter, the anti-rust oil composition is obtained.

[0028] Dip the high-carbon steel directly into the above-mentioned anti-rust oil for 3 minutes, and vibrate the high-carbon steel continuously. Then take it out and let it dry naturally.

Abstract

The invention provides a rust preventive oil. The rust preventive oil comprises a composite antirust agent and base oil. The composite antirust agent is a mixture of a rare earth-beta-dione complex and at least one of barium petroleum sulfonate, sodium petroleum sulfonate, calcium petroleum sulfonate, barium dinonylnaphthalene sulfonate, barium heavy alkyl benzene sulfonate, non-barium heavy alkyl benzene sulfonates, a lanolin magnesium soap, a lanolin aluminum soap, aluminium stearate, a oxidized petroleum ester barium soap and zinc naphthenate. The invention also provides a preparation method of the rust preventive oil. The preparation method comprises putting the base oil into a reaction vessel, adding the composite antirust agent into the base oil, stirring the mixture with heating to dehydrating the mixture, and then filtering to obtain the rust preventive oil. The rust preventive oil prepared by the invention can keep a rust-preventing effect for a long time in three environments of a temperature and humidity experiment, a salt spray experiment and an atmospheric corrosion resistance experiment, and thus can satisfy needs.

Description

technical field [0001] The invention relates to an antirust oil and a preparation method thereof. Background technique [0002] The problem of metal corrosion affects 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. In order to avoid corrosion, people have adopted a variety of techniques and methods to prevent the occurrence of metal corrosion. Among them, using antirust oil to protect metal products is one of the most commonly used protection methods at present. However, the existing anti-rust oil has a long drying time, and a thick oil film is formed after the parts are oiled, which affects the operation of the subsequent process and has a negative impact on the appearance of the sealed package. [0003] Chinese Patent Publication No. CN101407740 discloses a quick-drying metal thin layer antirust oil. The formula is: calcium petr...
