Abstract

The invention relates to a compound agent for marine lubricating oil. Its components and contents are: 25-45% of ultra-high alkali value sulfonate detergent, 40-60% of ultra-high alkali value phenate detergent, disperse 0-8% anti-wear agent, 0-4% anti-wear agent, 400SN / 500SN / 600SN10-20% high viscosity index I base oil; it can meet the viscosity and alkali value requirements of the marine BOB system process, and can compete with many domestic and foreign The system oil of the brand is mixed and prepared into cylinder oils with different alkali values, which has good adaptability, excellent performance in anti-wear, anti-oxidation and high-temperature detergency, and can meet the performance requirements of marine engines; the compound can be used on the basis of system oil It maintains good solubility stability and compatibility in oil, and will not affect the lubricating performance of cylinder oil.

Description

technical field [0001] The invention relates to a marine lubricating oil compounding agent, more precisely a special compounding agent for cylinder oil applied to a ship-borne BOB system. Background technique [0002] At present, the BOB online blending system (Blender-on-Board system) installed on ocean-going ships is to blend the marine system oil and the BOB system special marine lubricating oil compound through the automatic control system to prepare lubricating oil with any target base value. And it can be quickly switched to the engine to meet the needs of cylinder oils with different base values ​​for fuels with different sulfur content. [0003] The working process of the BOB system is: the system oil pumped from the oil tank to each lubricating point of the engine for lubrication, returns to the oil tank after the lubrication is completed, part of the lubricating oil is extracted through the side line, and the marine lubricating oil compound is passed through the BO...
