Embodiment 3

[0023] Embodiment 3 is the best implementation mode.

[0024] A method for preparing an anti-rust lubricant, the method is as follows: add fatty acid glycerides, modified soybean oil, and methyl silicone oil into a reaction kettle, heat to 45-48°C, stir and mix evenly, and then add corrosion inhibitors in sequence , sulfonate antirust agent, phosphate amine salt, antirust compound oil, sodium molybdate, ethanol, polyethylene glycol, glycerol, continue to stir for 50-55min, and finally add solid additives, anti-oxidation preservatives, non- The ionic surfactant continued to stir for 30-35 minutes to obtain the required anti-rust lubricant.

[0025] Table 2 is the technical indicator of the antirust lubricant of the present invention.

Abstract

The invention relates to the technical field of lubricants, particularly an antirust lubricant and a preparation method thereof. The antirust lubricant is composed of the following components in parts by mass: 45-65 parts of fatty glyceride, 22-28 parts of modified soybean oil, 5-10 parts of methyl silicone oil, 2-5 parts of corrosion inhibitor, 4-8 parts of non-ionic surfactant, 5-10 parts of sulfonate rust inhibitor, 4-8 parts of phosphate amine salt, 1.2-1.5 parts of antirust compound oil, 1.2-2.4 parts of sodium molybdate, 2-5 parts of polyethyleneglycol, 6-12 parts of glycerol, 0.02-0.06 part of 2,6-di-tert-butyl-para-cresol, 0.2-0.8 part of solid additive and 0.1-0.5 part of antioxidation preservative. By using the modified soybean oil as the base oil, the biodegradability is high. The antirust lubricant has the advantages of high viscosity index, favorable viscosity-temperature characteristics, favorable low-temperature fluidity, accessible raw materials and low cost. The antirust lubricant has excellent extreme pressure abrasion resistance since the vegetable oil polar molecules can form a protective film on the metal surface.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to an antirust lubricant and a preparation method thereof. Background technique [0002] Metal corrosion is a spontaneous trend in nature, and the anti-rust method of steel products is usually coated with anti-rust oil. Oiling not only brings pollution to products and the environment, but also brings a series of troubles to steel deep processing enterprises. Anti-rust lubricants have excellent performance in preventing rust and reducing the coefficient of friction, and are widely used in civil and industrial production. With the widespread use of anti-rust lubricants, anti-rust lubricants can enter the environment through various channels, causing pollution to the ecological environment. The anti-rust lubricants in the prior art are mainly used in the metal processing industry and the lubrication and anti-rust of some industrial metal reactors, including water-based lubricants ...
