Description
Technical Field
The patent relates to the field of marine lubricating oil, in particular to marine lubricating oil which can be universally used for marine cylinder oil, marine medium-speed engine oil and marine system oil.
Background
The marine diesel engine used in the ship transportation industry mainly has the functions of ship power, auxiliary power supply and the like, and the engine types of the marine diesel engine are divided into a low-speed two-stroke engine and a medium-speed four-stroke engine. Wherein, the lubricating oil of the low-speed two-stroke engine needs to use cylinder oil for ships and system oil; medium speed four stroke, requiring the use of medium speed oil. The marine diesel engine is characterized by large power, large volume and relatively complex fuel state, and can use fuels with the sulfur content of 3.5 percent, such as heavy residual oil, marine diesel oil and the like.
CN101935574A discloses an engine lubricating oil composition, in particular to a lubricating oil composition for heavy-duty diesel engines. It is characterized by containing a large amount of hydrotreating base oil. The composition also contains proper amount of alkyl salicylate, sulfurized alkylphenol salt, sulfonate, high molecular ashless dispersant, polyisobutylene bis-succinimide ashless dispersant, zinc dialkyl dithiophosphate, phenol antioxidant, amine antioxidant and sulfur-containing antioxidant antiwear agent. The lubricating oil composition can meet the specification requirements of CF-4 diesel engine oil specified in GB 11122-2006. The composition has simple formula, low cost and convenient preparation.
CN103710084A discloses a CF-4 grade diesel engine oil composition, which comprises the following components in parts by weight: a) 1-10 parts of a detergent; b) 1-15 parts of a dispersant; c) 1-10 parts of an antioxidant; d) 0-20 parts of a thickening agent; e) 0.03-2 parts of a pour point depressant; f) 0.01-1 part of an antifoaming agent; h) 50-88 parts of base oil; the technical scheme that the content of calcium in the composition is not less than 2000ppm, the sum of the contents of calcium and magnesium is not less than 2700ppm, and the content of nitrogen is not less than 500ppm can meet the quality grade requirement of GB11122-2006CF-4, and can be used in the industrial production of CF-4 grade diesel engine oil compositions. CF-4 has better high-temperature anti-oxygen property, detergency and dispersancy and wear resistance, ensures the cleanness of the engine under various fuel conditions, effectively prevents the piston ring from being bonded, prolongs the service life of the engine, and is particularly suitable for engines with complex fuels (such as higher sulfur content) and low-speed and high-torque output working conditions, such as military or civil diesel engines of generator sets, bulldozers, excavators, mining equipment, armored transport vehicles and the like.
CN101798545A discloses a lubricating oil composition, which comprises the following components by weight percent: 2.0-10.0% of high-temperature detergent; 2.0 to 10.0 percent of ashless dispersant; 0.2 to 2.0 percent of antioxidant antiwear agent; 0.5 to 3.0 percent of auxiliary antioxidant; pour point depressant 0.1-0.8%; 5.0 to 10.0 percent of viscosity index improver; 0.0015-0.0025% of antifoaming agent; the balance is hydrogenation process base oil; the method is characterized in that: the raw materials are easy to obtain, the production process is simple, the preparation is convenient, the faults of a diesel engine caused by lubrication can be reduced to the maximum extent, the service life of the engine is prolonged, the soot dispersion performance is excellent, the oil product shows excellent high-temperature detergency, polishing resistance and antioxidant thickening effect by optimizing a high-temperature detergent and an antioxidant antiwear agent, the main performance reaches ACEA E4 and API CH4 quality levels, and the oil requirement of a Douchi diesel engine is met. Therefore, the lubricating oil composition disclosed by the invention is suitable for a heavy-load high-speed four-stroke diesel engine.
The lubricating oil compositions disclosed in the above prior art are all suitable for use in high speed four stroke diesel engines for land use.
However, it should be noted that marine diesel engines are significantly different from high-speed four-stroke diesel engines used on land. The land-used high-speed four-stroke engine using light diesel oil as fuel is characterized by that its power is small, volume is small and fuel state is good, and the adopted lubricating oil is a lubricating oil composition whose main properties can be up to ACEA E4 and API CH4 quality grade. Land-based high-speed four-stroke engines are not used in the marine transportation industry because of their low power, high fuel requirements, and high lubrication requirements, and likewise, marine engines cannot be used on land. Based on the difference between land diesel engine and marine diesel engine, the performance of the lubricating oil required by the land diesel engine and the marine diesel engine is greatly different.
For marine engines, the lubricating oil used has stricter requirements, and the cylinder oil used for low-speed two-stroke engines has better acid neutralization performance and abrasion resistance; the system oil is required to have better oxidation resistance and cleaning and dispersing performance; the medium speed engine oil is required to have better base number retention performance, oxidation resistance and clean dispersing performance. The lubricating oil for land diesel engines mainly emphasizes soot dispersion and high-temperature detergency, and has larger performance requirement difference with the marine lubricating oil.
CN101082011A discloses a direct and quick kinetic energy oil with a self-repairing function, which consists of base oil and an additive, wherein the additive consists of a catalyst, minerals, a metal detergent, an antiwear agent, a dispersant, an antioxidant, a pour point depressant and an antifoaming agent. The kinetic energy oil which is direct and quick and has the self-repairing function is energy-saving and environment-friendly, and the oil change period is prolonged. Different from the formulation of the marine lubricating oil composition of the present invention.
Currently, in the field of marine lubricating oil production, different compound additive packages are commonly used separately to produce cylinder oil, system oil and medium speed engine oil. The main requirements of different marine oil varieties are different, for example, the marine cylinder oil is used once, so the requirement on the acid neutralization performance is higher; in the case of marine medium speed engine oil, since it is stored in an engine oil pan for a long time, it is required to have good oxidation resistance and sludge dispersibility. Different properties, when formulated into corresponding products, require different compounding agents to meet such specific properties.
However, this also brings about more storage tanks, more complicated management, and more equipment investment for the manufacturing plants and the compounder.
