Problems solved by technology

In order to improve the anti-rust performance, an attempt was made to add an anti-rust agent to the lubricating oil composition for marine diesel engines, but the addition of common anti-rust agents has the problem of mismatching with other components in the lubricating oil composition for marine diesel engines and poor anti-rust performance
So far, there is no relevant patent on the lubricating antirust oil composition for marine diesel engines

Embodiment 1~9

[0034] Add each component into the base oil in proportion at 55° C., stir for 0.5 to 5 hours to dissolve them all, and obtain a lubricating antirust oil composition for marine diesel engines. See Table 1 for details.

[0035] In Table 1, T704 is zinc naphthenate, T101 is calcium petroleum sulfonate with low alkali value, and T705 is barium dinonyl naphthalene sulfonate.

Embodiment 10

[0043] The thermal oxidation stability of the lubricating and antirust oil compositions for marine diesel engines in [Examples 1-9] was investigated. The results are shown in Table 3 and Table 4.

[0045]

[0046] Table 4

[0047]

[0048] As shown in Table 4, after adding suitable antirust additives, the lubricating and antirust oil composition for marine diesel engines not only passed the engine standard bench test, but also achieved medium and short-term antirust performance.

Abstract

The invention relates to a marine diesel engine lubricating anti-rust oil composition and an application thereof and mainly aims to solve the problem that parts inside a marine diesel engine are easy to corrode and rust and the like during short-term storage of an engine and marine transportation because an oil product in the prior art is used for an engine lubricating system after the marine diesel engine is manufactured. The problem is better solved through the technical scheme that the marine diesel engine lubricating anti-rust oil composition comprises the following components in parts by weight: 0.1-7.0 parts of antirust agent (a), 0.1-2.0 parts of antioxidant (b), 0.1-2.0 parts of extreme pressure antiwear agent (c), 0.1-3.0 parts of detergent (d), 0.1-3.0 parts of dispersing agent (e), 0.1-1.0 part of pour point depressant (f), 0.001-0.2 part of antifoaming agent (g) and 81.8-99.399 parts of base oil. The marine diesel engine lubricating anti-rust oil composition can be used in industrial production of marine diesel engine oil compositions.

Description

technical field [0001] The invention relates to a marine diesel engine lubricating antirust oil composition and its application. Background technique [0002] Marine diesel engines can be divided into main engine and auxiliary engine according to their role in the ship. As the main engine, it can be used as the propulsion power of the ship. If it is used as an auxiliary machine, it can be used as a power system to drive generators, air compressors or water pumps. Marine diesel engines are generally divided into high-speed, medium-speed and low-speed diesel engines. [0003] Usually, the manufacturing plant of marine diesel engines is not in the same area as the enterprise that builds ships. After a marine diesel engine is produced, assembled, and tested, it will take a long time to be stored from transportation, installation to normal use. . In this way, due to the influence of complex climate environment changes such as cold, heat and humidity, the main components insid...
