Abstract

The invention relates to the technical field of lubricants and particularly relates to a rustproof lubricant and a preparation method thereof. The rustproof lubricant comprises the following components in parts by mass: 40-50 parts of fatty acid glyceride, 20-30 parts of modified rapeseed oil, 4-8 parts of methyl silicone oil, 2-5 parts of a corrosion inhibitor, 4-8 parts of a nonionic surfactant, 5-9 parts of polyvinylpyrrolidone, 4-8 parts of a sulfonate rustproof agent, 3-7 parts of phosphates amine salt, 0.8-1.5 parts of a rustproof compound, 0.8-2.5 parts of sodium molybdate, 5-10 parts of ethanol, 2-5 parts of polyethylene glycol, 5-10 parts of glycerol, 0.2-0.6 part of a fungicide, 0.2-0.8 part of a solid additive and 0.1-0.5 part of an antioxidant corrosion-resistant agent. The rustproof lubricant has the beneficial effects that 1, the modified rapeseed oil is adopted as base oil, the advantages of high biodegradation rate, high viscosity index, good viscosity-temperature performance, excellent extreme pressure anti-wear property, good low-temperature fluidity, easily available raw materials and low cost are achieved; and 2, by adopting the rustproof lubricant, the advantages of high biodegradation rate and anti-wear friction-reducing capability are achieved, the friction pair bearing capacity is improved and the service life of the device is prolonged.

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 ...
