Problems solved by technology

[0003] Most of the existing lubricating oils use organic matter as the base fluid. The water solubility of the lubricating oil is poor, it is inconvenient to clean, and there are many residues; moreover, the raw materials are highly toxic, causing certain adverse effects on the operator and the environment.
At the same time, the components are complex and not energy-saving enough
And product performance still needs to be further improved

Abstract

The invention discloses waterborne lubricating oil containing lithium silicate and a preparation method thereof. The waterborne lubricating oil is prepared from the following raw materials in parts byweight: 48-87 parts of water-soluble base oil, 11-17 parts of lithium silicate, 10-16 parts of allantoin, 8-16 parts of seignette salt, 6-15 parts of gamma-polyglutamic acid and 4-8 parts of honey. The waterborne lubricating oil containing lithium silicate has the good water solubility and is convenient to wash; the raw materials are easy to get and environmentally friendly, the physical health of an operator is protected, and the environment is protected; the components are simple and more energy can be saved; and the waterborne lubricating oil can effectively improve the low temperature performance and the anti-wear performance of the lubricating oil, and the application range is wide.

Description

Technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an aqueous lubricating oil containing lithium silicate and a preparation method thereof. Background technique [0002] Lubricating oil is used in various types of machinery to reduce friction and protect the liquid lubricant of machinery and processed parts, mainly for lubrication, cooling, rust prevention, cleaning, sealing and buffering. The concept of lubricating oil additives is to add one or several compounds in the lubricant to give the lubricant some new characteristics or improve some of the existing characteristics in the lubricant. Additives are divided into antioxidants, anti-wear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and rust inhibitors, flow point improvers, and viscosity index increase. Agents and other types. [0003] Most of the existing lubricating oils use o...
