Abstract

The invention discloses a compound agent for marine oil, its preparation method and application, and relates to the technical field of marine oil. In terms of mass fraction, the raw materials of marine oil compounding agent include sulfonate 30‑50%, sulfurized alkylphenate 15‑30%, succinimide 20‑40% and alkyl salicylate 3‑10% ; Preferably, its raw materials include 35-45% of sulfonate, 20-27% of sulfurized alkylphenate, 25-35% of succinimide and 5-8% of alkyl salicylate. The preparation method of the marine oil compounding agent uses the formula provided in the above marine oil compounding agent as a raw material, and the compounding agent is prepared through simple mixing steps, which is suitable for adding to medium-speed cylindrical piston marine oil, and can significantly improve its water separation performance .

Description

technical field [0001] The invention relates to the technical field of marine oil, and in particular to a marine oil compounding agent, its preparation method and application. Background technique [0002] The marine oil compounding agent is used to be added to the base oil to improve various properties of the base oil, and is widely used in the marine oil. The medium-speed cylindrical piston engine oil has high requirements on water separation, and the general marine oil compound can not effectively improve the water separation performance of the base oil, especially the quality and performance of the domestic complex DCB medium-speed cylindrical piston marine oil compound. [0003] In view of this, propose this application. Contents of the invention [0004] The purpose of the present invention is to provide a marine oil compounding agent, which aims at effectively improving the water separation performance of the marine oil and making the appearance stability of the ma...
