Abstract
The invention discloses a preparation method of a nano copper lubricating oil additive. The method comprises the following steps: adding a modifier and shot copper to a ball mill according to the mass ratio of (1-3):6, and grinding for 11-12 hours at the rotating speed of 400-450r/min to obtain dry powder; adding the dry powder and absolute ethyl alcohol to another ball mill according to the ratio that 5-6mL of absolute ethyl alcohol is added per 1g of copper powder; adjusting the rotating speed at 350-500r/min, and carrying out ball-milling for 4-5 hours; removing absolute ethyl alcohol after ball-milling is finished, drying in vacuum and grinding, so as to obtain metal copper powder; mixing the copper powder with 500SN base oil at the mass ratio of (3-5):80; adjusting the rotating speed at 350-400r/min and carrying out ball-milling for 1-1.5 hours, so as to obtain the nano copper lubricating oil additive. By adopting the nano copper lubricating oil additive obtained by the technical scheme, the abrasion resistance of the base oil can be improved, and an experiment proves that the friction surface is repaired in different degrees.
Description
Technical field
The preparation method who the present invention relates to a kind of nano copper lubricating oil additive, belongs to technical field of lubricating oil.
Background technology
Copper nanoparticle has good antiwear and friction reduction property, can be used for quality lubricant, lubricating in especially suitable heavy duty, low speed and high-temperature vibrating situation.In recent years, the preparation of Nanometer Copper and application thereof have become one of focus of domestic and international field of nanometer technology research.Nano copper particle has the characteristics such as good tribological property, self-regeneration performance and environmental friendliness as lubricating oil additive, so Nanometer Copper has good application prospect in lubricating oil additive field.
The proportion that accounts for lubricating oil total amount due to gear of vehicle oilconsumption is larger, thereby the research and development of automotive gear oil becomes the main project of lubricating oil industry.Along with raising energy-conservation and that emission control requires, the requirement to automotive gear oil at many aspect of performances such as antiwear and antifrictions is also improving constantly.
Summary of the invention
First technical problem to be solved by this invention is: the preparation method that the nano copper lubricating oil additive that a kind of wear-resistant and antifriction performance is good is provided.
For addressing the above problem, the technical solution used in the present invention is: the preparation method of nano copper lubricating oil additive, the steps include: that by modifier and shot copper be that 1～3:6 adds ball mill in mass ratio, and rotating speed is 400～450r/min, grinds 11-12h, obtains dry powder; The dehydrated alcohol that adds 5～6mL by every 1g copper powder, dry powder and dehydrated alcohol are added in another ball mill together, adjust rotating speed 350～500r/min, ball milling 4-5h, after ball milling finishes, remove dehydrated alcohol, vacuum-drying, grinding, obtain copper powder, and copper powder is mixed with the mass ratio of 500SN base oil with 3～5:80, adjust rotating speed 350-400r/min ball milling 1-1.5h, obtain nano copper lubricating oil additive.
Beneficial effect of the present invention: the nano copper powder lubricating oil additive that technical solution of the present invention obtains, can improve the resistance to abrasion of base oil, experimental results show that friction surface has reparation in various degree.
