Embodiment 1

[0022] Add 500 kg of twice-hydrogenated mineral oil HV II2 (produced by Sinopec Shanghai Gaoqiao Branch) into the blending kettle and heat to 60°C; add magnesium petroleum sulfonate, sodium petroleum sulfonate, and calcium petroleum sulfonate with medium alkalinity , dodecenyl succinate monoester, heptadecenyl imidazolidinyl succinate, 2,6-di-tert-butyl p-cresol, continue heating to 110°C, and stir at constant temperature for 4 hours. Then add 350 kg of twice hydrogenated mineral oil HV II2, stir evenly, and circulate and filter with a suction filter until the oil temperature drops to 75°C for canning. Each component and its weight percentage are shown in Table 1, and the product properties are shown in Table 2.

Embodiment 2

[0024] Add 550 kg of No. 10 transformer oil into the blending kettle and heat it to 65°C; add magnesium petroleum sulfonate, sodium petroleum sulfonate, calcium petroleum sulfonate with high alkali value, zinc naphthenate, dodecenylsuccinic acid mono Esters, 2,6-di-tert-butyl-a-dimethylamino-p-cresol, and nonylphenol polyoxyethylene (4) ether were heated to 115°C and stirred at constant temperature for 2.5 hours. Then add 300 kg of No. 10 transformer oil, stir evenly, and circulate and filter with a suction filter until the oil temperature drops to 75°C for canning. Each component and its weight percentage are shown in Table 1, and the product properties are shown in Table 2.

Embodiment 3

[0026]Add 600kg of HVI75SN into the blending kettle and heat to 80°C; add petroleum magnesium sulfonate, nonylphenol ether phosphate, high alkali value calcium petroleum sulfonate, zinc naphthenate, dodecenyl succinate monoester , N-amino-a-naphthylamine, pentaerythritol oleate, continue heating to 120°C, and stir at constant temperature for 2 hours. Then add 240 kg of base oil, stir evenly, and circulate and filter with a suction filter until the oil temperature drops to 75°C for canning. Each component and its weight percentage are shown in Table 1, and the product properties are shown in Table 2.

Abstract

The invention relates to a method for producing an anti-rust oil composition and mainly solves the problems of the prior art that the production of the anti-rust oil composition requires long time and high energy consumption and an oil product is susceptible to over oxidation which influences anti-rust effect. For better solving the problems, the method adopts a technical proposal that: 1) 40 to 80 weight percent of base oil is heated with stirring to be between 50 and 100 DEG C; 2) an antirust and an antioxidant in required amount are added into the base oil of the step 1), and the antirust, the antioxidant mixture and the base oil are continuously heated to be between 95 and 130 DEG C and stirred at a constant temperature for 0.5 to 6 hours to form a mixture I; and 3) the balance of base oil is added into the mixture I, and the base oil and the mixture I are uniformly stirred to form the anti-rust oil composition. The method can be used in the industrial production of the anti-rust oil composition.

Description

technical field [0001] The invention relates to a production method of an anti-rust oil composition, in particular to a production method of an anti-rust oil composition which is demanding on moisture. Background technique [0002] The surface anti-rust protection technology of metal plates and strips has always been a field of research by countries all over the world. There are many problems in the process of strip antirust protection. The reasons are various. In addition to insufficient research on antirust materials and a low overall level, the production process of antirust oil will also affect the antirust performance of the product. [0003] The solubility of water in mineral oil, especially light mineral oil, is very small, that is to say, the water content in base oil is very low, usually below 150ppm. Polar groups in antirust molecules, such as carboxyl groups in sulfonate and carboxylate antirust agents, ester groups in fatty acid esters and phosphate ester antiru...
