Special lubricating oil for diesel engine of ocean-going ship and preparation method of special lubricating oil

Abstract

The invention discloses special lubricating oil for a diesel engine of an ocean-going ship. The lubricating oil comprises the following components in parts by mass: 32 to 45 parts of basic oil, 11 to 18 parts of bright stock 150BS, 3 to 6 parts of microcrystalline wax, 1 to 4 parts of nanosilicon dioxide, 5 to 9 parts of oleic acid, 2 to 6 parts of alkyl diphenylamine, 1 to 3 parts of a complexing agent H8744B and 3 to 5 parts of a viscosity index improving agent OCP. The special lubricating oil for the diesel engine of the ocean-going ship is high-performance engine lubricating oil which is designed by a special novel technology formula for researches by specially aiming at the characteristics of long-time operation, complicated working condition, large thermal load, frequent replacement of diesel oil in different districts of the diesel engine of the ocean-going ship. The special lubricating oil is outstanding in high-temperature cleanliness and dispersion performance, so that sticking of a piston ring and polishing of a cylinder sleeve, which are caused by a fuel direct ejection technology, can be effectively prevented, and high cleanness of the engine can be kept; compared with the oil of a common supercharged diesel engine, the special lubricating oil disclosed by the invention is higher in oxidation stability and thermal stability.

Description

technical field

[0001] The invention relates to a lubricating oil and a preparation method thereof, in particular to a special lubricating oil for ocean-going ship diesel engines and a preparation method thereof, belonging to the technical field of lubricating oil preparation. Background technique

[0002] With the increase in the number of construction machinery and transportation vehicles in various countries in the world, the exhaust gas emitted by diesel engines has become one of the main pollution factors to the earth's environment. How to take measures to protect the earth's environment on which human beings depend is an urgent task. my country has formulated relevant standards since the 1980s, taking environmental protection as a major issue. At the same time, countries around the world have also begun to find and explore other methods and adopt other effective technical measures to actively reduce and control pollutant emissions.
