Embodiment 1

[0022] An anti-oxidation and anti-corrosion lubricating oil composition, which contains the following ingredients in weight percentage: 68% of mineral base oil, 6% of thiophosbutene octyl alkyl zinc salt, 2% of thionphosbutene octyl alkyl zinc salt, 2% of alkali 2% of bis-octyl zinc salt of phosphion, 7% of thiadiazole derivatives, 6% of polyvinyl n-butyl ether, 8% of dienyl succinimide, and 1% of pour point depressant.

[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 poly Vinyl n-butyl ether, 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 stirrin...

Abstract

The invention relates to a lubricating oil and especially relates to an antioxidant anticorrosion lubricating oil composition. The antioxidant anticorrosion lubricating oil composition comprises, by weight, 65-70% of mineral base oil, 5-8% of zinc dialkyl dithiophosphate-T202, 2-3% of zinc dialkyl dithiophosphate-T203, 2-3% of zinc dialkyl dithiophosphate-T204, 5-8% of thiadiazole derivative, 6-11% of polyvinyl-N-butylether, 6-8% of dialkenyl succinimide, and 0.5-1% of a pour point depressant. The antioxidant anticorrosion lubricating oil composition adopts easily available raw materials, can be produced by simple processes, is convenient for preparation, has wear, oxidation and corrosion resistance, can prevent metal oxidation and catalysis aging, delays an oil product oxidation speed, prevents contact between an acidic object and metal, produces a protection film, has wear resistance, 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 anti-oxidation and anti-corrosion lubricating oil composition. 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 dewax...
