Abstract

The invention relates to a marine cylinder oil complexing agent. The cylinder oil complexing agent comprises, by weight, 15-25% of an ultra-high base number sulphonate clearing agent, 35-45% of an ultra-high base number phenate clearing agent, 20-30% of an ultra-high base number naphthenate clearing agent, 0-8% of a dispersing agent, 0-4% of an antiwear agent and 10-20% of high viscosity index Class I base oil 400SN / 500SN / 650SN. The cylinder oil complexing agent is characterized in that the complexing agent meets requirements of a blender-on-board (BOB) system technology for the viscosity andthe base number of the complexing agent, can be prepared on line, is wide in application range, can be mixed with domestic and foreign system oil of various models and brands to be prepared into cylinder oil of different base numbers, is excellent in wear-resistant performance, antioxidant performance and high-temperature clearing performance, meets performance requirements of marine engines, is good in solution stability and compatibility and does not affect the lubrication performance of the cylinder oil.

Description

technical field [0001] The invention relates to a formula of a 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 marine system oil and BOB system special cylinder oil compounding agent through the automatic control system to prepare cylinder 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, and then returned to the oil tank after the lubrication is completed, a part of the lubricating oil is extracted through the side line, and the compound agent of the cylinder oil passes through...
