Mineral-oil-based high-temperature chain oil and preparation method thereof

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.
