Description
Technical Field
The invention relates to a preparation method of diene graphene lubricating oil.
Background
At present, the traditional lubricating oil generally adopts chemical raw material additives (sulfur, phosphorus, sulfur-phosphorus, element and boron antiwear agents) to perform antiwear and lubricating functions, and achieves good lubricating effect on machinery in high-speed operation. However, in long-time mechanical operation, because of different high-speed operation, high shear, high-temperature and high-speed shaft and shaft, wheel and wheel, cylinder and shaft and other operation, the traditional antiwear additive cannot be kept stable, and can accelerate oxidation to cause machine part abrasion, residue falling and circulating damage, increased resistance, power consumption, oil consumption, larger friction sound and the like.
Since graphene is a kind of material which is more heat-resistant than diamond and softer than silica gel, the wear resistance of lubricating oil is very suitable, and when the machine is in operation, the cylinder is operated at high temperature and high speed, the wear resistance is very large, and the characteristics of the graphene are most suitable when the graphene is softer than silica gel (if hard particles are in the middle of the cylinder shaft, the surface is worn, and the friction sound is very large). Therefore, graphene is the best choice and best effect for wear resistance at present, but is very important in selection because of the multiple types (number of layers) of graphene in the market at present. Since it is harder than diamond and softer than silica gel, it is impractical to achieve abrasion resistance during fabrication, since graphene's extra hard and soft' is difficult to grind from large particles to small particles, and particles of a grade less than 0.5um must be best made and selected. If the chemical raw materials are used for dissolving the graphene into liquid which is dissolved with the lubricating oil into a whole, the anti-wear effect is reduced by 90%, and the effects of no oil saving and instability are generated when the graphene is used for new and old automobile lubricating oil. Therefore, the vehicle head can vibrate due to overlarge particles; if the particles are too small, the anti-wear effect will be poor. Therefore, the optimal graphene anti-wear concentrated oil can be prepared by selecting the raw materials, the process sequence and the proper weight proportion.
