Embodiment 1

[0027] According to the parts by weight in Table 1, take by weighing 20 grams of calcium petroleum sulfonate, 15 grams of 2,6-di-tert-butyl-p-cresol, 10 grams of octyldiphenylamine, 5 grams of barium dinonylnaphthalenesulfonate and 50 grams of base oil, heated and stirred at 50-60°C for 0.5-1 hour until completely uniform. See Table 1 for details.

[0028] Weighing 1 to 2% by weight of the marine oil composition is added to the marine oil product, heated and stirred evenly, and the test oil is prepared for use.

[0029]The use effect of the composition, that is, the water separation performance, was evaluated by the marine oil-water separation test method (SH / T0619). During the test, first measure 98 ml of test oil in the conical tube, then add 2 ml of distilled water, and stir with a stirrer at a speed of 3600±100 rpm for 30 seconds until the oil and water are emulsified. Place the centrifuge tube in a centrifuge, centrifuge for 2 hours under the condition of a relative cen...

Embodiment 2～14

[0031] Prepare the bunker oil composition and test oil according to the steps of [Example 1], but change the consumption and composition of each component. The composition of the bunker oil composition is shown in Table 1.

[0032] The water-separation performance of each test oil was tested, and the test results are shown in Table 2. Other properties of the oil used in the test, such as detergency and dispersibility, anti-oxidation and anti-corrosion properties, etc., were not affected.

Abstract

The invention relates to a marine oil composition and a use thereof, and a purpose of the present invention is to mainly solve the problem of poor water separation performance of the marine lubricating oil in the prior art. A technical scheme of the marine oil composition is characterized in that: the marine oil composition adopts the following components, by weight, a) 0.05-50 parts of a detergent, a dispersing agent or a mixture comprising the detergent and the dispersing agent; b) 0.01-30 parts of a phenol compound; c) 0.01-30 parts of an amine compound; d) 20-90 parts of base oil. The phenol compound has a chemical general formula represented by a formula (I), wherein in the formula (I), R and R' are selected from H, alkyl containing 1-8 carbon atoms or hydroxyl, but R and R' are not simultaneously selected from H or hydroxyl, R'' is selected from H, alkyl containing 1-8 carbon atoms, hydroxyl or saturated monocarboxylic ester. According to the technical scheme provided by the present invention, the problem in the prior art is effectively solved, and the technical scheme is applicable for the industrial production of the marine oil composition.

Description

technical field [0001] The present invention relates to a marine oil composition and its application. Background technique [0002] Marine system oils can be used for the lubrication of moving parts in the crankcase of low-speed crosshead diesel engines. The structural feature of the marine two-stroke low-speed crosshead diesel engine is that there is a diaphragm between the cylinder and the crankcase. Therefore, the lubrication of the crankcase system is an independent circulation system, and the oil is sent to the bearings, gears and cam moving parts by the oil pump. Lubricate to ensure proper operation. In some oil-cooled models, the marine system oil also acts to cool the pistons. Therefore, the marine system oil should have excellent detergent and dispersant, anti-wear and thermal oxidation stability, so as to prevent the oil from oxidizing and deteriorating on the top and bottom of the piston at high temperature, forming deposits such as sludge paint film and organic...
