preparation example Construction
[0041] The present invention also provides a kind of preparation method of antirust oil, comprises the following steps:
[0042] a) mixing and reacting raw materials comprising polyhydric alcohols and dicarboxylic acids to generate complex esters;
[0043] b) Heat the base oil to 60°C-80°C, add barium petroleum sulfonate, barium dinonylsulfonate, dodecenylsuccinic acid, benzotriazole and di-n-butyl phthalate in sequence, and then Add the prepared complex ester, stir until the material is completely dissolved and then filter;
Embodiment 1
[0045] Add 815kg of solvent oil into the kettle, raise the temperature to 60°C, add 100kg of barium petroleum sulfonate, 30kg of barium dinonylsulfonate, 5kg of dodecenylsuccinic acid, 4.5kg of benzotriazole, and phthalic acid 45.5kg of di-n-butyl ester, 10kg complex ester, complex ester is obtained by the reaction of dipentaerythritol ester, adipic acid and neodecanoic acid with a mass ratio of 4:5:3, stirred for two hours, and filtered after the material is completely dissolved to obtain product.
Embodiment 2
[0047] Add 845kg of polyalphaolefin synthetic oil into the kettle, raise the temperature to 70°C, add 40kg of barium petroleum sulfonate, 20kg of barium dinonylsulfonate, 15kg of dodecenyl succinic acid, 4.5kg of benzotriazole, and 45.5kg of di-n-butyl phthalate, 30kg of complex ester, the complex ester is obtained by the reaction of trimethylolbutane, glutaric acid and decanol with a mass ratio of 3:4:2, stir for two hours, and wait for the material to dissolve After complete filtration, the product is obtained.

Abstract
The invention provides antirust oil, which comprises the following components in percentage by weight: 75 to 87.5 percent of base oil, 1 to 3 percent of complex ester, 4 to 10 percent of barium petroleum sulfonate, 2 to 6 percent of barium dinonyl sulfonate, 0.5 to 1.5 percent of dodecylene succinic acid, 0.3 to 0.8 percent of benzotriazole and 3 to 6 percent of di-n-butyl phthalate, wherein the complex ester is obtained by reacting raw materials comprising polyalcohol and dicarboxylic acid. The antirust oil provided by the invention has the advantages of oil-film antirust oil and soft-film antirust oil and long antirust time. A workpiece coated with the antirust oil can be directly put into use without being cleaned or being provided with an additional lubricating additive. The antirust oil can be applied to long-term rusting protection of metal workpieces, such as internal surface rusting protection of engines, gearboxes and pumps.
Description
technical field [0001] The invention relates to the field of antirust of metal materials, in particular to an antirust oil and a preparation method thereof. Background technique [0002] At present, the annual loss of steel due to corrosion and rust is about 10% to 20% of the world's annual steel production, resulting in a waste of a lot of resources. During the storage period after metal processing, short-term rust prevention of metals with anti-rust oil can effectively inhibit the corrosion and rust of metals. Antirust oil can be divided into oil film type, soft film type and hard film type according to the film forming state. [0003] Hard film antirust oil forms a hard film, which is used for long-term rust prevention of workpieces and is difficult to remove. Among them, oil film type and soft film type antirust oil account for about 93% of the total consumption of antirust oil, and are the mainstream products in the market. [0004] Oil film type antirust oil is gene...
