Embodiment 1

[0020] The present embodiment is the preparation method of STS dehydration antirust oil, comprises the following steps:

[0021] Add 55kg of barium petroleum sulfonate and 16kg of liquid paraffin into the reaction kettle, control the temperature at 120°C, and stir for 2h; add 14kg of dodecenylsuccinic acid, cool down to 80°C, and stir for 2h; add 10kg of kerosene, 5kg of silver thiosulfate , and stirred at room temperature for 2 hours to obtain STS dehydrated antirust oil.

[0022] Barium petroleum sulfonate is selected from Jinan Jinyu Chemical Industry, brand T701, as an anti-rust additive, barium petroleum sulfonate is brown, translucent, semi-solid, suitable for antirust agent in antirust oil, the static state of barium petroleum sulfonate The corrosion test is good. It has no corrosion effect on steel, brass, copper, aluminum alloy, zinc and other metals. After heating, it has good oil solubility and can be adsorbed on the metal surface to form a protective film to preven...

Embodiment 2

[0028] The difference with embodiment 1 is:

[0029] Add 57kg of barium petroleum sulfonate and 14kg of liquid paraffin into the reaction kettle, control the temperature at 120°C, and stir for 2h; add 14kg of dodecenylsuccinic acid, cool down to 80°C, and stir for 2h; add 8kg of kerosene, 5kg of silver thiosulfate , and stirred at room temperature for 2 hours to obtain STS dehydrated antirust oil.

[0030] The average molecular weight of barium petroleum sulfonate is 1200. Liquid paraffin has a molecular weight of 500. The initial boiling point of kerosene is 158°C and the final boiling point is 200°C. The density of kerosene is 0.88kg / m 3 , 20°C. The viscosity of kerosene is 1.32mm 2 / s, 40°C.

[0031] The anti-rust oils prepared in Examples 1-2 were subjected to the damp heat test in accordance with the national standard, and all were qualified. The anti-rust oil was applied to the surface of the metal material and placed outdoors for 33 days without obvious rust.

Abstract

The invention discloses STS dehydration anti-rust oil and a preparation method thereof.The method comprises the following steps that barium petroleum sulfonate and liquid paraffin are added into a reaction kettle, the temperature is controlled to be 120 DEG C, and stirring is conducted for 2 h; adding dodecenylsuccinic acid, cooling to 80 DEG C, and stirring for 2 hours; and adding kerosene and silver thiosulfate, and stirring at normal temperature for 2 hours to obtain the STS dehydration anti-rust oil. The film-forming property of the anti-rust oil is stable, and the anti-rust oil has the characteristics of being antibacterial, anti-rust and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of antirust oil preparation, and in particular relates to an STS dehydrated antirust oil and a preparation method thereof. Background technique [0002] Corrosion is one of the main forms of damage to metal parts, which will cause great losses to mechanical equipment. In order to avoid corrosion of fasteners and other metal parts and reduce the losses caused by them, anti-rust oil is usually applied. The existing patent number is CN201911082782.7 A rust-proof oil and its preparation method include the following components: dodecenylsuccinic acid; barium petroleum sulfonate; triethanolamine; engine oil; palmitic acid; 4-methylbenzene Triazole; Sodium dodecylbenzenesulfonate; Buffer solution; Water. The existing anti-rust oil discloses that the components contain an antibacterial agent, and the antibacterial agent requires additional preparation costs, and the anti-corrosion performance of the aqueous emulsio...
