Abstract

The invention discloses anti-freezing lubricating oil, and belongs to the technical field of fine chemical engineering. The anti-freezing lubricating oil is prepared from the following raw materials in parts by weight: 80-100 parts of base oil, 4-5 parts of dodecyl acidic phosphite, 3-4 parts of unsaturated fatty acid, 2-3 parts of glyceryl acrylate, 3-8 parts of ethylene glycol, 1-3 parts of lithium 12-hydroxystearate, 0.1-2 parts of sodium dodecyl sulfate and 0.5-3 parts of oleamide. The lubricating oil special for an engine provided by the invention is stable in property, and the auxiliaryadditives can optimize the lubricating, anti-corrosion, anti-coagulation, anti-oxidation and pressure-resisting performance of the base oil, the cleaning performance is good, and oil sludge and carbondeposit can be reduced. Meanwhile, the anti-freezing lubricating oil can be used at a low temperature (higher than or equal to -30 DEG C).

Description

technical field [0001] The invention relates to an antifreeze lubricating oil, which belongs to the technical field of fine chemicals. Background technique [0002] Lubricating oil is divided into four categories according to its source: animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. [0003] The amount of petroleum lubricating oil accounts for more than 90% of the total amount, so lubricating oil often refers to petroleum lubricating oil. It is mainly used to reduce the friction between the surfaces of moving parts, and at the same time, it has the functions of cooling, sealing, anti-corrosion, anti-rust, insulation, power transmission, and cleaning impurities for machinery and equipment. It mainly uses lubricating oil fraction and residual oil fraction from crude oil distillation unit as raw material. The most important properties of lubricating oil are viscosity, oxidation stability and lubricity, which are closely related to the com...
