Background technology
Frictional wear is ubiquitous spontaneous phenomenon, and lubricating oil reduces friction reduce and resist one of the most effective approach of wearing and tearing, and carry out in-situ immobilization at the volley to wear surface is the target that greaser author constantly pursues always.Lubricating oil is generally made up of base oil and additive two portions, and base oil is lubrication main body of oil, and decide the essential property of lubricating oil, additive then can make up and improve some performance of base oil.Lubricating oil is by its source point animal and vegetable oil, petroleum oil and ucon oil three major types.The consumption of petroleum oil accounts for total consumption more than 97%, and therefore lubricating oil often refers to petroleum oil.Be mainly used in reducing the friction between moving parts surface, machinery equipment had to cooling, sealing, anticorrosion, antirust, insulation, power transmission, clean the effects such as impurity simultaneously, mainly with from the lubricating oil distillate of crude unit and residue oil fraction for raw material.The topmost performance of lubricating oil is viscosity, oxidation stability and oilness, and the composition of they and lubricating oil distillate is closely related.Viscosity is the important quality index of reflection lubricating oil flow, different working conditionss has different viscosity requirement, the machinery of heavy loading and lower velocity will select thick oil, oxidation stability represents that oil product is in environment for use, due to the resistance of oxidation that oxygen in temperature, air and metal catalytic effect show.After oil oxidation, can generate tiny bituminous matter according to working conditions is main carbon shape material, the paint-like material in viscous or paint film, or the hydrous matter of viscosity, thus reduces or lose its use properties.Oilness represents the Wear vesistance of lubricating oil.Lubricating oil additive concept is one or more compounds added in lubricant, obtains certain new characteristic or improve more existing characteristics in lubricant to make lubricant.Additive divides by function types such as mainly containing antioxidant, anti-wear agent, friction modifier (having another name called oiliness improver), extreme-pressure additive, purification agent, dispersion agent, froth suppressor, corrosion prevention rust preventer, flow point activator, viscosity index improver.The additive sold in market is all generally the combination product of above each single additive, and difference is exactly the composition difference of single additive and the ratio difference of the inner several single additive of composite additive.
The overwhelming majority of investigation and application is organic additive both at home and abroad at present, and little to the research of inorganic additives, and it applies phoenix feathers and unicorn horns especially.Along with the deep development studied in lubricating oil field, people find that a lot of inorganic additives shows good performance gradually, some is even obviously better than organic additive, but, because inorganic additives is insoluble or be insoluble in oil, also difficulty is stably dispersed in lubricating oil, and its application have received restriction.In the last few years, Chinese scholars, in the process of seeking anti wear and friction reducing additives, found that some nanoparticle all significantly can improve the tribological property of lubricating oil by friction self-repair function, reached the object of antiwear and antifriction.Therefore, nano particle has been become the emphasis of tribological field research in recent years as the research that slip additive is applied in lubricating oil.
In production work, the crankshaft-and-connecting-rod watt iron powder produced and mud oil, usually can affect the running of apparatus; of a specified duration even accelerates the aging of apparatus; lubricating oil additive of the prior art, antiwear and friction reduction property, thermostability are not also fine, and effectively can not solve iron powder and mud oil problem.
