Abstract

The invention discloses a method for improving stability of lubricating oil. Raw materials comprise castor oil, an antifoaming agent, water and a viscosity conditioning agent; 50-60 parts of the castor oil is heated to 40-45 DEG C, an additive, 5-10 parts of the antifoaming agent, and 50-60 parts of water are added, and stirring is carried out at a rotating speed of 35-40rps for 10-20 minutes; 5-10 parts of the viscosity conditioning agent is added, stirring is carried out at a rotating speed of 30-35rps for 20-30 minutes, and the stability of the lubricating oil is improved. A self-made additive is added, the disadvantage of bad oxidation stability existed in traditional plant oil is overcome, and the lubricating oil has good stability.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil production, and in particular relates to a method for improving the stability of lubricating oil. Background technique [0002] With the increasing awareness of environmental crisis, more and more attention has been paid to the pollution caused by the infiltration, leakage, spillage and improper handling of a large amount of lubricating oil in the process of production, use and discharge. From the perspective of development trend, biological The degradable environment-friendly lubricating oil and its additives will replace the existing lubricating oil. [0003] Since 1991, an extensive research and development program on vegetable oil-based (bio)lubricants has been initiated in the United States.
