Embodiment 1

[0035] This example shows a high anti-wear extreme pressure and anti-wear and anti-friction lubricating oil. According to the mass ratio, the components are as follows:

[0036] Hydroisomerization dewaxing III base oil accounts for 35%-45%, polyalphaolefin PAO accounts for 35%-45%, lubricating oil additives 10%-25%, and the described lubricating oil additive components include:

[0037] Tungsten disulfide particle additive: 1.5%-2.5%;

[0038] Nitrogen-containing borate fat additive 0.8%-1%;

[0039] Detergent and dispersant 2%-3%;

[0040] Antioxidant and anticorrosion agent 1.5%-2%;

[0041] Pour point depressant 0.3%-0.7%;

[0042] Viscosity index improver 6%-15%;

[0043] Defoamer 0.01%.

[0044] Further, the nitrogen-containing boric acid fat additive was synthesized by using oleic acid, diethanolamine and boric acid as raw materials, using DNW type resin as a catalyst, and synthesized the nitrogen-containing boric acid fat additive under reduced pressure at 155-160°...

Embodiment 2

[0064] This example shows a preparation process of high anti-wear extreme pressure and anti-wear and anti-friction lubricating oil, which specifically includes the following steps:

[0065] 1) Mix 35%-45% hydroisomerization dewaxed Group III base oil and 35%-45% polyalphaolefin PAO, stir at a constant speed, and heat to 48~58°C within 10 minutes, and keep warm for 20 minutes , to obtain base oil;

[0066] 2) Prepare tungsten disulfide particle additives, specifically: prepare tungsten disulfide nanorods by ball milling-self-transformation method; then use chemical precipitation-desulfurization method and ball milling-desulfurization method to prepare inorganic fullerene (IF) disulfide Tungsten particles, the prepared tungsten disulfide particles have a diameter of 10-15 μm and a length of 0.1-2 μm; the preparation of WS2 nanorods by ball milling and self-conversion method is to prepare the precursor by ball milling the mixed powder of WS2 and S, and then WS2 nanorods were pre...

Abstract

The invention relates to a preparation process of lubricating oil with high wear-resistant extreme pressure and wear-resistant antifriction property. The preparation process comprises the following steps: mixing 35%-45% of hydroisomerization dewax type-III base oil with 35%-45% of poly-alpha olefin PAO, stirring at a uniform speed, heating the mixture to 48-58 DEG C within 10 minutes, and thermally insulating for 20 minutes, so as to obtain base oil; preparing a tungsten disulfide particle additive, adding the tungsten disulfide particle additive into the base oil, and stirring at a uniform speed for 15 minutes, wherein tungsten disulfide particles account for 1.5%-2.5% of the total components; preparing a nitrogen-containing boric acid ester additive, and stirring at a uniform speed for 15 minutes; adding a viscosity index improver, thermally insulating, stirring until the kinematic viscosity and the pour point meet standards, and continuing to thermally insulate; adding 2%-3% of a clean dispersing agent; adding 1.5%-2% of an oxidation and corrosion inhibitor; adding 0.3%-0.7% of a pour point depressant; adding 0.01% of an antifoaming agent; and continuing to stir at a uniform speed, heating to 62-66 DEG C within 10 minutes, and thermally insulate for 30 minutes, so as to obtain a finished product.

Description

technical field [0001] The invention relates to the technical field of lubricating grease and its preparation. Specifically, it shows a preparation process of lubricating oil with high anti-wear extreme pressure and anti-wear and anti-friction properties. Background technique [0002] "Lubrication" is a traditional equipment management technology. With the development of modern equipment to large-scale, precision and automation, there are higher requirements for the traditional technology of "lubrication", which is mainly reflected in how to adopt advanced lubrication technology and deployment methods , Reduce abnormal wear of equipment, reduce spare parts consumption, reduce energy loss, and ensure safe operation of equipment. Existing large and heavy-duty vehicles have large operating loads, high summer temperatures, and large wear and tear, which have a great impact on the life of the vehicles. [0003] Therefore, it is necessary to provide a high anti-wear extreme press...
