Problems solved by technology

Mineral base oils come from fossil crude oil, are non-renewable, and waste oil is difficult to degrade after discharge, causing environmental pollution and other factors have been more and more restricted; synthetic base oils are mainly represented by polyalphaolefin oil, which has good oxidation resistance performance and low temperature performance, however, the complex preparation process and high equipment investment limit the large-scale promotion of this type of base oil; biological base oil is mainly represented by vegetable oil, which has the advantages of regeneration and easy degradation of waste oil, but , the antioxidant stability of vegetable oil and poor compatibility with additives, resulting in limited application

Abstract

The invention discloses environment-friendly lubricating oil taking bio-oil as base oil and a preparation method of the lubricating oil. The environment-friendly lubricating oil comprises the following raw materials in percentage by mass: 0.4-3.2 percent of a purification dispersant, 1.2-2.8 percent of an antioxidant, 1-3.6 percent of a lubricity improver, 0.6-3.6 percent of a collaborative lubricant, 0.05-0.5 percent of a degradation catalyst, 1-5.5 percent of a viscosity index improver and 86-95 percent of base oil. The method for preparing the lubricating oil comprises the sequential unit operations such as refining, dehydrating, mixing and dispersing. Compared with the conventional product or technology, the product disclosed by the invention is environment-friendly, the base oil is reproducible, the compatibility of the base oil and the additive is good, the anti-oxidation stability is high, the lubricating oil has good and stable lubricating performance, the preparation method is simple in process, and industrial production is easily realized.

Description

technical field [0001] The invention relates to an environment-friendly lubricating oil and a preparation method thereof, in particular to an environment-friendly lubricating oil with bio-oil as base oil and a preparation method thereof. Background technique [0002] Lubrication is one of the main technologies to reduce friction and reduce material wear. The use of lubricating oil lubrication is the main measure for reducing friction and anti-wear of mechanical parts. In recent years, with the increasingly intensified service conditions of various mechanical components, new requirements have been put forward for the lubricating performance of lubricating oil, especially the improvement of environmental protection requirements, so that lubricating oil has good environmental protection while maintaining high-efficiency lubricity Performance, some additives with good lubricating properties in the past are no longer suitable for the use of lubricating oils with modern environmen...
