Embodiment 1

[0022] A car lubricating oil composition rich in cleaning factors, containing the following ingredients in weight percentage: 68% of hydrogenated base oil, 6% of sodium metal base, 2% of calcium phenolic compound, 2% of magnesium phenolic compound, ashless Extreme pressure antioxidant 5%, viscosity index improver 10%, dispersant 6.5%, pour point depressant 0.5%.

[0023] Preparation method: first prepare the base oil, add the pour point depressant to the small mixing tank according to the above amount, pump in an appropriate amount of base oil to dilute and stir, heat up to 85-95°C, and after the pour point depressant is completely miscible, add the viscosity Index improver, continue stirring at constant temperature until completely dissolved. Then, pump the prepared base oil into the large blending tank, then pump the prepared base oil into the large blending tank, control the temperature at 60-70°C, and continue stirring until the mixture is uniform. Add various addi...

Abstract

The invention relates to lubricating oil and especially relates to a cleaning factor-rich lubricating oil composition for vehicles. The cleaning factor-rich lubricating oil composition comprises, by weight, 60-75% of hydrogenated base oil, 5-8% of metalized sodium, 2-3% of a calcium-phenol compound, 2-3% of a magnesium-phenol compound, 5-8% of an ash-free extreme pressure antioxidant, 6-11% of a viscosity index improver, 6-8% of a dispersant and 0.5-1% of a pour-point depressant. The cleaning factor-rich lubricating oil composition adopts easily available raw materials, can be produced by simple processes, is convenient for preparation, has wear resistance, prevents deposition on the surface, maximally reduces engine fault caused by lubrication and prolongs an engine service life.

Description

technical field [0001] The invention relates to lubricating oil, in particular to an automotive lubricating oil composition rich in cleaning factors. Background technique [0002] Non-volatile oily lubricant. According to its source, it can be divided into three categories: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 97% 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. Mainly use the lubricating oil fraction and residual oil fraction from the crude oil distillation unit as raw materials, and remove or reduce the substances that form free carbon through solvent deasphalting, solvent dew...
