There are two types of sulfurized olefins: one is sulfurized isobutylene, and the other is sulfurized long-chain alkyl olefins with a sulfur content of 10%-20%. Sulfurized isobutene is a very important kind, because of its light color, good oil solubility and good extreme pressure, it is widely used in various gear oils, hydraulic oils, and lubricating greases; but sulfurized isobutene does not have very good anti-wear properties. The smell is also relatively large, coupled with the corrosiveness to copper, it is rarely used in metal processing oil (liquid).
Natural oils and fats have one or more carbon-carbon bonds that react with sulfur to form sulfurized oils. Since natural oil has excellent lubricating oil, the viscosity of the oil increases after combining with sulfur, and the fiber structure also changes, so it shows good anti-wear performance; but because natural oil is selective for mineral oil solubility Therefore, the esterification of natural oil not only retains the anti-wear properties of the oil, but also increases the sulfur content, and the oil solubility is no longer a problem. Therefore, sulfurized esters have very good application prospects in metalworking fluids and other industrial lubricants.
Other sulfurized products, such as guanoic acid esters, are almost no longer used because of their foul odor; dibenzyl disulfide, because it has only a solubility of 2.5% in mineral oil, is not suitable for use in metalworking fluids and is only used for In ordinary gear oil and synthetic oil; the use of alkyl polysulfides is limited due to the instability of sulfur element, poor stability, serious copper corrosion, and sulfur precipitation during storage.
Therefore, in summary, in industrial lubricating oils and metal working fluids, the most widely used are still sulfurized fats and sulfurized esters.
