Problems solved by technology

[0003] At present, the vast majority of lubricating oils use mineral oil as the base oil, which has poor biodegradability in the natural environment, and its accumulation in the environment will easily pollute the ecological environment and cause a series of environmental problems
The environmental pollution problem that lubricating oil brings is paid more and more attention to, so the application that replaces mineral oil with vegetable oil as lubricating oil base oil is also more and more extensive, but the stability performance of the lubricating oil that existing vegetable oil is made as base oil and insufficient biodegradability

Abstract

The invention discloses lubricating oil biological base oil and a preparation method thereof. The lubricating oil biological base oil comprises the following components: 30-55 parts of plant base oil,1.5-2.2 parts of trimethylchlorosilane, 15-25 parts of toluene, 3.2-3.8 parts of acetic acid, 4-6 parts of anhydrous ether, 3.9-4.5 parts of hydrogen peroxide, 1.5-2 parts of triethylamine and 3-5 parts of a catalyst. An environmentally friendly plant oil raw material replaces a petroleum-based raw material to prepare the biological environmentally friendly lubricating oil, raw material reagent resources are abundant, environmental pollution is small, the problem that petroleum resources at the present stage is in shortage can be solved, meanwhile, the requirement for environmental protectionis met, according to the prepared biological lubricating oil base oil, organosilicone is used for modifying vegetable oil, after modification, the oxidation stability and lubricating property of thevegetable oil are improved obviously, an oil product derived from the vegetable oil has good biological degradability, and compared with mineral oil, the lubricating oil biological base oil is more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and more specifically relates to a biological base oil for lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. [0003] At present, the vast majority of lubricating oils use mineral oil as the base oil, which has poor biodegradability in the natural environment, ...
