Antirust lubricant and preparation method thereof

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 ...

AI Technical Summary

Problems solved by technology

However, the existing bio-rust lubricants and anti-rust lubricating mineral oils have poor biodegradability and strong accumulation of ecotoxicity, which seriously pollute land, rivers and lakes, endanger the ecological environment and ecological balance, and cause adverse effects on the environment.
