Embodiment 1

[0023] An anti-wear vehicle lubricating oil composition, containing the following components in weight percentage: 69% hydrogenated base oil, 6% zinc dithiophosphate, 10% phosphoric acid ester, 5% acidic phosphate, polymer ashless dispersant 9%, pour point depressant 1%.

[0024] Preparation method: first prepare the hydrogenated 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, Then, pump the prepared hydrogenated base oil into the large blending tank, control the temperature at 60-70°C, and continue stirring until the mixture is uniform. Add various additives to the mother liquid tank according to the amount, dilute and mix with the adjusted base oil, and control the miscibility temperature at 60-70°C. After the mother liquid is dissolved, pump it into the large mixing tank to mix with the ...

Abstract

The invention relates to lubricating oil and especially relates to a wear-resistant lubricating oil composition for vehicles. The wear-resistant lubricating oil composition comprises, by weight, 60-75% of hydrogenated base oil, 5-8% of zinc dithiophosphate, 6-12% of phosphate, 4-6% of acid phosphate, 8-10% of a polymer ashless dispersant and 0.5-1% of a pour-point depressant. The wear-resistant lubricating oil composition adopts easily available raw materials, can be produced by simple processes, is convenient for adjustment, 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-wear vehicle 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 dewaxing, solvent ref...
