Abstract

The invention provides degradable plant-based lubricating oil. The lubricating oil is prepared from the following raw materials in parts by weight: 50-100 parts of modified vegetable oil, 1-3 parts ofa chelating agent, 2-10 parts of graphite nanopowder, 1-5 parts of calcium aluminate powder, 1-4 parts of a high-efficiency antioxidant, 2-7 parts of stearic acid, 1-5 parts of arachidic acid, 0.5-1part of an antibacterial synergist, 10-20 parts of polyethylene glycol and 1-2 parts of a defoaming agent. The prepared lubricating oil has good degradability, low-temperature performance and good lubricating effect, can adapt to most application occasions, and is greatly improved in rust resistance and lubricating effect, free of great change in friction coefficient at a high temperature and highin stability, and therefore, the lubricating oil has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a degradable vegetable-based lubricating oil and a preparation method thereof. Background technique [0002] Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in a large amount (about 95%), but in some applications, products formulated with synthetic base oils and bio-oil base oils must be used, thus making these two base oils develop rapidly. The most popular lubricating oil products in my country's market are mostly petroleum-based lubricating oils, which are difficult to degrade and remain in the environment for almost a long time. The annual global consumption of lubricating oil is 36-40 million tons, of which about 10 million tons of lubricating oil directly enters the ecological environment where humans live due to leakage, splashing, oil vapor ev...
