Embodiment 1

[0019] Embodiment 1: formula is:

[0020]

[0021] The production method is:

[0022] Add antirust additives, antioxidants and extreme pressure agents to mineral oil together, heat to 85±5°C and stir for about 60±5min to confirm that the solution is transparent, then add pour point depressant and another mineral oil to the solution, and then Stir at 40±5°C for about 20±5min, and pack it in barrels for storage after passing the QC test.

[0023] In the foregoing, the antirust additive is a sulfonate.

[0024] In this example, the quality characteristics of the lubricating and antirust oil for water-displaced steel plates are that a small amount of water is allowed to remain on the steel plate, and the requirements for drying the steel plate are not so harsh, so that the process requirements are reduced, energy is saved, and the use effect is improved. In order to completely prevent rust on the surface of the steel plate for a period of time.

[0025] The invention is suit...

Abstract

The invention discloses water displacement type steel plate lubrication and rust prevention oil. The water displacement type steel plate lubrication and rust prevention oil is obtained by adding an antirust agent, a lubricant, a pour point reducer and an antioxidant to mineral oil, and used for sealing storage of cold-rolled steel coils and rust prevention of intermediate processes. The greatest advantage of the water displacement type steel plate lubrication and rust prevention oil is high water displacement property; by the adoption of the water displacement type steel plate lubrication and rust prevention oil, a small amount of moisture left on a leveled cold-rolled sheet can be separated from the sheet by means of an antirust additive with high adsorbability and small surface tension, so that a rust prevention effect is well realized; meanwhile, degreasing can also be achieved, degreasing rate reaches 80%, and follow-up processing can not be affected; rust prevention time is long, no oil patch residue is left, low temperature resistance is realized, environment friendliness is realized, no odor is generated, cost is reasonable, price is moderate, and extensive use can be conducted; the frequency of rust prevention maintenance can be reduced, maintenance cost can be reduced, environment friendliness and safety are realized, and three-waste emission is avoided in production and use.

Description

technical field [0001] The invention relates to an IPC classification C10M lubricating composition, especially a water-displacing lubricating antirust oil for steel plates. Background technique [0002] After the steel plate is cold-rolled and annealed, it needs to be coated with anti-rust oil to ensure that it will not rust during storage and transportation. However, after leveling, a small amount of leveling liquid will remain on the steel plate. If it cannot be removed, apply it directly Applying general steel plate anti-rust oil will cause local rust and affect the performance. [0003] Anti-rust oil has water displacement and inactivation of corrosive substances, exerts anti-rust performance, and has a blocking effect on corrosive environments. Anti-rust additives are attached to the metal surface, molecules form an adsorption film, and a waterproof oil layer structure is formed on it. The oil film molecules of the adsorption film and the additive molecules of the oil...
