一种用于甲醇发动机润滑油组合物及其制备方法
摘要：
本发明提供了一种甲醇发动机润滑油组合物及其制备方法，涉及润滑油技术领域，包括如下组分：高碱值油溶性磺酸盐清净剂，占所述润滑油组合物总质量的2‑5％；二烷基二硫代磷酸锌抗氧抗腐剂，占所述润滑油组合物总质量的1‑8％；油溶性聚醚类破乳剂，占所述润滑油组合物总质量的0.5‑2％；和主要量的润滑油基础油。本发明解决甲醇发动机的高功率密度带来的润滑剂氧化和润滑系统零部件的磨损问题。
摘要（英）：

The invention provides a lubricating oil composition for a methanol engine and a preparation method thereof, belonging to the technical field of lubricating oil. The lubricating oil composition comprises a high-base-number oil-soluble sulfonate clearing agent, which accounts for 2 to 5% of the total mass of the lubricating oil composition; a zinc dialkyl dithiophosphate oxidation and corrosion inhibitor, which accounts for 1 to 8% of the total mass of the lubricating oil composition; an oil-soluble polyether de-emulsifier, which accounts for 0.5 to 2% of the total mass of the lubricating oil composition; and base oil for lubricating oil, which is the majority of the lubricating oil composition. The lubricating oil composition overcomes the problems of oxidation of a lubricant and wearing of components of a lubricating system caused by high power density of the methanol engine in the prior art.
