Problems solved by technology

However, the preparation process of alkyl salicylate is complex and the product cost is high
Calcium sulfonate and alkyl salicylate are compounded to prepare lubricating oil composition. Although the advantages of both are combined, the additives are prone to turbidity or precipitation during the storage and use of the oil, which affects its further use.

Abstract

The invention discloses a high-temperature-resisting lubricating oil composition for an engine. The high-temperature-resisting lubricating oil composition is prepared from the following raw materials in parts by weight: 890 to 950 parts of basic oil, 5 to 20 parts of glyceryl oleate, 6 to 12 parts of calcium alkyl salicylate, 12 to 20 parts of sulfurized calcium alkyl phenolate, 1 to 5 parts of a preservative, 0.5 to 2 parts of an anti-wearing agent, 5 to 10 parts of an antioxidant, 0.8 to 3 parts of an anti-rusting agent, 0.5 to 1.5 parts of a pour point depressant, 0.2 to 0.8 part of an anti-foaming agent and 0.6 to 2 parts of a demulsifying agent. The high-temperature-resisting lubricating oil composition disclosed by the invention has good high-temperature detergency property, dispersity, anti-polishing property, anti-oxidization property and anti-wearing property; the raw materials are easy to obtain, and the requirements of large-span engine oil on rheological properties are met.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high temperature resistant lubricating oil composition for engines. Background technique [0002] Engine lubricating oil, commonly known as engine oil, can lubricate and reduce friction, assist cooling and cooling, seal and prevent leakage, prevent rust and corrosion, shock absorption and buffering, etc. for the engine, and is known as the "blood" of the car. The engine is the heart of the car. There are many metal surfaces that rub against each other in the engine. These parts move fast and have high temperature. The working temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life. Engine oil is usually composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can...
