Problems solved by technology

[0005] my country's anti-rust oil products have formed a scale, with an annual output of more than 20,000 tons. The annual demand of my country's anti-rust oil market is between 100,000 and 120,000 tons, and the annual market demand for anti-rust additives is also more than 30,000 tons. Product quality and variety can not meet the needs of users
The main problem of domestic anti-rust products is that the anti-corrosion effect of anti-rust oil is not ideal during the storage of steel products

Embodiment 1

[0018] The lubricating antirust oil of the present invention is composed of the following components by mass percentage: 18% of barium petroleum sulfonate, 12% of calcium petroleum sulfonate, 10% of sodium petroleum sulfonate, 5% of ancient oil, dodecenylsuccinic acid- Ethanolamine 5%, polyvinyl alcohol 10000 5%, 62# engine oil 45%.

[0019] The preparation method of described dodecenylsuccinic acid monoethanolamine, comprises the steps: in 250 liters of reactors, first adds a certain amount of dodecenylsuccinic acid and an appropriate amount of monoethanolamine (dodecenylsuccinic acid : monoethanolamine=1:2 molar ratio), start stirring, then gradually heat up to 120°C, react at this temperature for 6 hours, and naturally cool the product at room temperature to obtain dodecenylsuccinic acid monoethanolamine.

[0020] The preparation method of the lubricating and antirust oil includes the following steps: put 62# machine oil into the reactor, heat up to 50°C, and then add calci...

The lubricating rust-preventative oil product possesses both rust prevention effect and lubricating effect, is capable of satisfying process rust prevention requirements in mechanical processing, and satisfying workpiece sealing rust prevention requirements; and lubrication machine processing technology requirements in mechanical industry workpiece manufacturing process can be satisfied; and the lubricating rust-preventative oil can be used for lubricating maintenance in mechanical equipment operation process.

Description

[0001] Technology [0002] The invention relates to a lubricating and anti-rust oil product suitable for the inter-process and sealing anti-rust of mechanical workpieces in the machining process of stainless steel, cast iron, aluminum alloy, copper alloy and other materials in the automobile industry, aerospace and other mechanical manufacturing industries. Background technique [0003] According to statistics, the weight of iron and steel products that cannot be used due to corrosion and rust in the world is approximately equivalent to 10% to 20% of the annual output of metals. Metal corrosion can cause increased maintenance and early replacement of machinery and equipment, while corrosion of metal products reduces the accuracy and sensitivity of the equipment, affects the use of the equipment, and even causes the equipment to be scrapped. Therefore, the problem of metal corrosion has been plagued by product processing, transportation, storage, etc. in the manufacturing indus...
