Abstract

The invention relates to an anti-rust and wear-resistant lubricant and a preparation method thereof. The anti-rust and wear-resistant lubricant comprises the following raw materials in parts by weight: 20-27 parts of mineral oil, 12-19 parts of simethicone, 10-12 parts of citric acid, 2-3 parts of nano-graphite powder, 5-13 parts of polyvinyl alcohol, 2-5 parts of polyvinylpyrrolidone, 8-17 parts of octadecylamine, 5-9 parts of polydimethylsiloxane, 30-45 parts of ethylene glycol and 10-15 parts of ethanol. By jointly and reasonably compounding the mineral oil and other additives, not only is the lubricating performance of the lubricant effectively improved, but also the anti-rust and wear-resistant performances of the lubricant are improved. Meanwhile, by reasonably compounding polyvinyl alcohol, polyvinylpyrrolidone and octadecylamine, the interaction of the additives in the solvent are more remarkable, so that the anti-rust and wear-resistant performances of the lubricant are greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to an antirust and antiwear lubricant and a preparation method thereof. Background technique [0002] With the continuous development of industry, some necessary products in the industry also develop and grow, and a large amount of oil pollution is produced in industrial production, and the cleaning of oil pollution is of great significance for continuing production. The anti-rust lubricant has become a must-have for some manufacturers. If the product is poorly selected, especially for particularly sophisticated equipment, even a little carelessness will lead to damage or even damage to the equipment. [0003] Metal corrosion is generally a process in which metals are oxidized and lost due to oxidation-reduction reactions with substances in contact, and a chemical reaction in which part or all of the surface is peeled off, dissolved or softened. "Rust" is ofte...
