Abstract

The invention discloses a preparation technology of high-wear resistance and self-repairing lubricating oil. The preparation technology comprises the following steps: mixing 35-45% of hydroisomerizeddewaxed class-III base oil and 35-45% of polyalphaolefin PAO, stirring at a constant speed, heating to 48-58 DEG C in 10min, and preserving heat for 20min to obtain base oil; preparing a nanometer calcium carbonate particle additive, adding the nanometer calcium carbonate particle additive into the base oil, and stirring at a constant speed for 15min, wherein the nanometer calcium carbonate particle additive accounts for 1-2% of the total composition; preparing nanometer nickel particles, adding into the base oil, stirring at a constant speed for 15min, and heating to 55-60 DEG C in 10min, wherein the prepared nanometer nickel particles account for 1-2% of the total composition; adding a viscosity index improver, then preserving heat while stirring till the kinematic viscosity and the pourpoint reach the standards, and continuing preserving the heat; adding 2-3% of a cleaning dispersant; adding 1.5-2% of an antioxidant anti-corrosion agent; adding 0.3-0.7% of a pour point depressant;adding 0.01% of a defoaming agent; continuing stirring at a constant speed, heating to 62-66 DEG C in 10min, and then continuing preserving the heat for 30min 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 highly wear-resistant self-repairing lubricating oil. 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 wear-resistant self-healing lubricating oil preparation process to...
