Embodiment 1

[0021] The sulfonic acid amine of this example was synthesized according to the following method:

[0022] Add sodium petroleum sulfonate and tetradecylamine into the reaction kettle at a molar ratio of 1:1.5, draw out the air from the reaction kettle until the pressure is less than or equal to 100Pa, and fill it with nitrogen until the pressure is 3MPa;

[0023] After heating to 115° C., stirring at constant temperature for 120 min, extracting nitrogen gas until the air pressure is less than 300 Pa, heating to 135° C., stirring at constant temperature for 70 min, and distilling out excess tetradecyl amine under reduced pressure; the sulfonic acid amine can be prepared after cooling.

[0024] An environmentally-friendly water-displacement anti-rust oil composition is composed of the following components in parts by mass: 84 parts of D100, 8 parts of sulfonamides, 5 parts of oleic acid, and 3 parts of basic aluminum stearate.

Embodiment 2

[0026] The sulfonic acid amine of this example was synthesized according to the following method:

[0027] Add sodium petroleum sulfonate and hexadecylamine into the reactor at a molar ratio of 1:1.7, draw out the air from the reactor until the pressure is less than or equal to 100Pa, and fill with nitrogen until the pressure is 3.2MPa;

[0028] After heating to 110°C, stirring at constant temperature for 140min, extracting nitrogen until the pressure is less than 300Pa, heating to 140°C, stirring at constant temperature for 80min, and distilling excess hexadecylamine under reduced pressure; the sulfonic acid amine can be prepared after cooling.

[0029] An environmentally friendly water-replacement type anti-rust oil composition is composed of the following components in parts by mass: 86 parts of D80, 8 parts of sulfonamides, 2 parts of fatty acid polyvinyl ether, and 4 parts of basic aluminum stearate.

Embodiment 3

[0031] The sulfonic acid amine of this example was synthesized according to the following method:

[0032] Add sodium petroleum sulfonate and heptadecylamine into the reaction kettle at a molar ratio of 1:2.0, draw out the air from the reaction kettle until the pressure is less than or equal to 100 Pa, and fill with nitrogen until the pressure is 3.5 MPa;

[0033] After heating to 120°C, stirring at constant temperature for 120min, extracting nitrogen until the pressure is less than 300Pa, heating to 130°C, stirring at constant temperature for 60min, and distilling excess heptadecylamine under reduced pressure; the sulfonic acid amine can be prepared after cooling.

[0034] An environmentally-friendly water-displacement anti-rust oil composition is composed of the following components in parts by mass: 48 parts of D60, 37 parts of D70, 10 parts of sulfonamides, 3 parts of oleic acid, and 2 parts of basic aluminum stearate.

Abstract

The invention relates to the technical field of metal surface treatment, in particular to environment-friendly water replacing antirust oil and a preparation technique thereof. The environment-friendly water replacing antirust oil is prepared from the following components in parts by mass: 75-90 parts of base oil, 5-15 parts of antirust agent, 2-5 parts of a dehydrator and 1-5 parts of an auxiliary agent. By adopting the self-made antirust agent, the environment-friendly water replacing antirust oil has excellent water replacing property and antirust property, can meet the European and American environment-friendly demands and solves the problem of rust protection and corrosion resistance of processed parts exported to the Europe and America, and meanwhile, the production cost of a clientis lowered greatly.

Description

Technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an environmentally-friendly water-displacement type anti-rust oil and its preparation technology. Background technique [0002] In the metal processing industry, because it is reserved for storage or cannot be processed in the next process in a short period of time, it must be stored in a warehouse. During the inventory process, the metal will be more or less affected by the surrounding environment. corrosion. Corrosion will affect its own characteristics and hinder its subsequent processing or use. The annual loss due to metal corrosion is huge, and the significance of protection is particularly important. Especially in the cutting process, after using water-based cutting fluid for cutting and water-based cleaning agent for cleaning, certain water stains will remain on the surface of the workpiece. If you spray anti-rust oil without dehydration function, the water s...
