Abstract

The invention discloses a regenerated high-performance lubricating grease of waste internal combustion engine oil and a preparation method thereof. The preparation method comprises the steps of adding deep refined waste internal combustion engine oil and fatty acid into a reaction container, slowly heating till the fatty acid is completely dissolved, dissolving lithium hydroxide into water and then adding the solution into a reaction kettle, performing saponification for 2-3 hours at 100-110 DEG, heating to 140 DEG C, adding 1/4 of the formula quantity of the waste internal combustion engine oil, heating to 190-210 DEG C, refining at a high temperature for 10-20 minutes, adding the remaining waste internal combustion engine oil, cooling to be below 160 DEG C, adding an antioxidant, an extreme pressure agent, an oiliness agent and a thickening agent, then performing post treatment with a homogenizer or by cyclic shearing, filtering and packing. The produced lubricating grease has the characteristics of multiple effects, universality and the like, also has good lubricating performance and extreme pressure anti-wear performance, and can meet the requirements of most bearings for lubrication and protection and realize low-cost recycling of the waste internal combustion engine oil.

Description

technical field [0001] The invention belongs to the field of resource regeneration, and in particular relates to a formula and a production process for producing high-performance lubricating grease by using waste internal combustion engine oil through fine filtration and adding internal combustion engine lubricant. Background technique [0002] At present, my country is the second largest lubricating oil consumer in the world. With the growth of lubricating oil consumption, the amount of waste oil replaced by vehicles and equipment is increasing. Improper disposal of waste oil will not only cause waste of resources, but also cause irreversible damage to the environment. [0003] At present, foreign hydrogenation regeneration technology is the most advanced technology in the field of waste oil regeneration. However, due to the scattered oil sources in our country, there are many types of waste lubricating oil, the quantity is small, and the quality is unstable, so it is not s...
