Abstract

The invention relates to the technical field of lubricating oil production, in particular to an environment-friendly lubricating oil, which is made of the following raw materials in parts by weight: 105-160 parts of plant-based synthetic oil, 2-8 parts of modified extreme pressure agent, modified viscosity index 2-4 parts of anti-wear agent, 3-6 parts of anti-wear agent, 2-4 parts of antirust agent, 4-7 parts of antioxidant, 1-3 parts of defoaming agent and 120-150 parts of water; the vegetable base synthetic oil It is made from the following raw materials in parts by weight: 25-45 parts of castor oil, 75-95 parts of rapeseed oil, 10-20 parts of palm oil, 5-12 parts of boric acid and 8-15 parts of triethanolamine. The lubricating oil of the invention has the characteristics of no pollution, environmental protection, easy degradation and excellent performance under low temperature conditions; in addition, the raw materials are easy to obtain and the cost is low, the application range is wider, the effect is stable, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to an environment-friendly lubricating oil. Background technique [0002] Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and vegetable oil base oils. Mineral base oils are widely used and used in a large amount (about 90%), but in some applications, products formulated with synthetic base oils and vegetable oil base oils must be used, thus making these two base oils develop rapidly. [0003] Vegetable oil-based lubricants are environmentally friendly lubricants, such as soybean oil, rapeseed oil, cottonseed oil, corn oil, etc. In fact, the earliest lubricants that entered the market were German rapeseed oil synthetic lubricants. However, rapeseed oil is easy to solidify at low temperature, and the low temperature performance after esterification is not ideal. In view of this, an environment-friendly lubricati...
