Abstract

The invention relates to a preparation method of a super-low friction lubricating oil additive. The preparation method comprises the following steps: weighing a certain amount of graphene and lubricating oil, and feeding the graphene and the lubricating oil into mortar; manually grinding for 15 to 20 minutes until the materials are uniformly mixed to obtain a primary mixed solution; mixing the primary mixed solution with a stabilizer dissolved in absolute ethyl alcohol, adding a mixture into a beaker, and carrying out ultrasonic dispersion at a certain temperature for 40 to 60 minutes; mixing the mixed solution subjected to ultrasonic dispersion with the lubricating oil in the first step, adding a mixture into a ball grinding mill, carrying out grinding reaction and collecting mixed oil; adding the mixed oil into a friction wear testing machine for detecting the tribological properties of the oil. According to the method disclosed by the invention, super-low friction of castor oil or PAO (Polyalpha Olefin) oil can be realized.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a preparation method of an ultra-low friction lubricating oil additive. Background technique [0002] With the advancement of industrial technology and the development of economic technology, the demand for energy continues to increase, and the energy crisis becomes increasingly severe. Lubricating oil, as a lubricating material for engines, axles and other components, mainly plays the role of lubrication and wear reduction. play a vital role in the process. [0003] The operation of the machine depends on the relative movement of the parts, which is bound to be accompanied by friction and wear. Severe friction and wear will also affect the normal operation of the machine. Lubrication is the most common and effective way to solve the friction and wear caused by the operation of the machine. In the role of lubricating oil Under the circumstances, the lubricating oil can al...
