Abstract

The invention discloses an oil composition for a marine diesel engine and a preparation method and application thereof, and mainly solves the technical problem that a demulsifier needs to be added into the oil composition for the marine diesel engine to improve the oil-water separation performance in the prior art. The oil composition for the marine diesel engine is prepared from the following components in parts by mass: 0.1-20 parts of a clearing agent; 0.1-20 parts of a dispersant, 0.6-15 parts of an antioxidant; 0.001-1 part of an anti-foaming agent; an 50-98 parts of base oil. The preparation method of the marine diesel engine oil composition comprises the following steps: adding the clearing agent, the dispersing agent, the antioxidant and the anti-foaming agent into the base oil atthe temperature of 50-60 DEG C, performing stirring for 0.5-3 hours, and performing complete dissolving to obtain the marine diesel engine oil composition. The present invention discloses the application of the marine diesel engine oil composition in marine diesel engines, thereby better solving the problems. The marine diesel engine oil composition and preparation method and application thereof are suitable for industrial application of lubrication of marine diesel engines.

Description

technical field [0001] The invention relates to a marine diesel engine oil composition, a preparation method and an application thereof. Background technique [0002] Marine oil-water separation performance refers to the ability of marine oil to be easily emulsified when in contact with water, or the resulting emulsion is not stable, and oil-water separation can occur after staying in the circulating oil tank for a certain period of time or passing through the oil separator. Marine diesel engine oil will inevitably come into contact with water during use. The main additives in the formulation of marine diesel engine oil, such as detergents and dispersants, all have certain polarities and have a certain binding force with water. If the water separation performance of the oil product Not good, different degrees of emulsification will occur after stirring, and foam will be generated, which will affect the pressure of the engine oil, and the diesel engine may be seriously damage...
