Abstract

The invention discloses mineral-oil-based high-temperature chain oil and a preparation method thereof, belonging to the field of chain oil production. The high-temperature chain oil is prepared from the following raw materials in proportions by weight: high-pressure hydrogenated mineral oil of kettle bottom vacuum residue, a high-temperature antioxidant, a detergent, a dispersant, an extreme-pressure anti-wear agent, a rust inhibitor and an antifoaming agent. Compared with the prior art, the mineral-oil-based high-temperature chain oil disclosed by the invention has the characteristics of lowevaporation loss, almost no smoke, no carbon deposition, excellent lubricating properties and wear resistance and the like, and can be widely applied to high-temperature chain lubrication occasions below 300 DEG C.

Description

technical field [0001] The invention relates to the field of high-temperature chain oil production, in particular to mineral oil-type high-temperature chain oil and a preparation method thereof. Background technique [0002] High-temperature chain oil must meet the needs of lubrication during chain movement in high-temperature environments. It requires the oil to be resistant to high temperature during use, basically free of oil fume, free of oil sludge and high-temperature oxidized carbon deposits and paint films on the chain, and at the same time protect the chain to reduce chain wear. Due to the limitations of the above conditions, the high-temperature chain oil in the prior art has always been produced and used with synthetic oil as the base oil. However, synthetic oil has the disadvantages of resource shortage and high production cost, and its use as high-temperature chain oil cannot be recycled, resulting in a lot of waste of resources and energy.
