Problems solved by technology

[0003] The development of environmentally friendly marine stern oil in my country is relatively late. At present, domestic marine stern oil mostly uses marine system oil, and the base oil is mostly mineral oil. The use of compound additives has not considered biodegradability and biotoxicity. Large lubricating oil companies Castrol, Man, Klueber, etc. all have their own environmentally friendly stern shaft oil products

Embodiment 1

[0027] [Example 1] (in 100 grams, the same below)

[0028] Table 1

[0029]

[0030] Heat and stir pentaerythritol stearate and trihydroxypropane oleate at a constant temperature of 60°C to obtain mixed oil A. Add composite additive package ADDITIN M 93.001, sulfurized vegetable oil fatty acid ester, phosphate, succinic acid half ester derivatives to mixed oil A, and continue stirring for 40 minutes at a constant temperature of 60°C to prepare mixed oil B. Cool the mixed oil B at room temperature to obtain a clear and transparent lubricating oil for marine stern shafts. The properties are shown in Table 11.

Embodiment 2

[0032] Table 2

[0033]

[0034] Heat and stir pentaerythritol stearate and neopentyl glycol oleate at a constant temperature of 60°C to obtain mixed oil A. Add composite additive package ADDITIN M 93.001, sulfurized vegetable oil fatty acid ester, phosphate, and succinic acid half ester derivatives to mixed oil A, and continue stirring for 40 minutes at a constant temperature of 60°C to prepare mixed oil B. Cool the mixed oil B at room temperature to obtain a clear and transparent lubricating oil for marine stern shafts. The properties are shown in Table 11.

Embodiment 3

[0036] table 3

[0037]

[0038] Heat and stir pentaerythritol stearate and trihydroxypropane stearate at a constant temperature of 60°C to obtain mixed oil A. Add composite additive package ADDITIN M 93.001, sulfurized vegetable oil fatty acid ester, phosphate, succinic acid half ester derivatives to mixed oil A, and continue stirring for 40 minutes at a constant temperature of 60°C to prepare mixed oil B. Cool the mixed oil B at room temperature to obtain a clear and transparent lubricating oil for marine stern shafts. The properties are shown in Table 11.

Abstract

The invention relates to a stern shaft oil composition and application thereof. The stern shaft oil composition comprises, by weight, a) 85 to 99 parts of base oil, b) 0.2 to 5 parts of a composite additive bag ADDITIN M 93.001, c) 0 to 2 parts of phosphate, d) 0 to 4 parts of sulfurized aliphatic ester of plant oil; and e) 0 to 1 part of a hemisuccinate derivative. The prepared stern shaft oil composition can be used for lubrication of the stern shaft part of a ship.

Description

technical field [0001] The invention relates to a stern shaft oil composition and its application. Background technique [0002] The stern shaft is also known as the tail shaft. One end of the tail shaft is connected to the propeller, and the other end is connected to the gearbox or coupling joint and then connected to the engine, which has the function of sealing and lubricating. At present, most domestic ship stern shaft oils are mainly mineral oils. In nautical operations, due to harsh conditions, large vibrations generated during propeller operation, and other causes of average damage such as sediment and fishing nets in the operating environment, it is inevitable The failure of the stern shaft sealing device will lead to the infiltration of sea water or the leakage of oil. Due to the poor biodegradability and biological toxicity of mineral oil, it will pollute the ecological environment. In addition, the latest Vessel General Permit (Final 2013 VGP) issued by the US En...
