The grinding fluid of body, metal material, ingredient environmental protection preparation is simple, and dispersion performance is stablized, and lubrication, cooling performance are outstanding, can be effective
Improvement Grinding Machining Quality.
Background technique
In Grinding Process, not only occurs to cut but also occur delineation and scratching between grinding wheel and material, generate a large amount of mill
Heat is cut, grinding area temperature is up to 400~1000 DEG C or so, and at this high temperature, material can deform and burn, grinding wheel
It can be seriously worn, grinding quality decline.Grinding can all use grinding fluid in general, by a large amount of grinding heat band
It walks, reduces the temperature of grinding area.According to pertinent literature: grinding fluid, which is efficiently used, can be improved cutting speed 30%, reduce temperature
To 100~150 DEG C, cutting force l0%~30% is reduced, extends 4~5 times of grinding wheel service life.
Grinding fluid type is very more, is commonly divided into two major classes type: Water-soluble grinding fluid and oil-soluble grinding fluid, water-soluble
Grinding fluid can be divided into again: emulsion, semi-synthetic, fully synthetic.Its oil-soluble grinding fluid main component is mostly mineral oil.It is water-soluble
Emulsion oil content 50% or so in grinding fluid, semi-synthetic oil content 5-40%, fully synthetic not oil-containing, mainly by water-based composition
It is formed with water；Water-soluble grinding fluid its with good cooling effect, and prepare convenient, low in cost, not easy to pollute.
Ionic liquid is exactly the liquid being composed entirely of ions, it is generally by organic cation and inorganic anion institute group
At.First ionic liquid nitro ethamine is found that early in 1914, but the progress in this field thereafter is slow, until
1992, the strong 1- ethyl-3-methylimidazole tetrafluoroborate ion liquid of low melting point, resistant to hydrolysis, stability is synthesized
After ([EMIM] BF4), the research of ionic liquid is just rapidly developed, and a series of ion liquid system has been subsequently developed that were.
Initial ionic liquid is mainly used for electrochemical research, and ionic liquid is as green solvent in organic polymer, lubrication in recent years
Field is taken seriously.
Carbon nanotube is as a kind of important monodimension nanometer material, due to its unique electricity, optics and engineering properties,
Just the extensive research interest of people is caused at the beginning of the discovery.Due to model ylid bloom action power strong between carbon nanotube and very
Weak dissolubility makes carbon nanotube be difficult to be dissolved into water and other organic solvents, and which greatly limits its answering in the liquid phase
With.In order to solve this problem, different types of compound, such as surfactant, polymer and as green solvent
Ionic liquid etc. is used to dispersing Nano carbon tubes.It is living to make it have surface by chain alkyl is introduced in ionic liquid molecules
Property for dispersing Nano carbon tubes being capable of better dispersing Nano carbon tubes.
The application of solid lubricant has had very long history, graphite, molybdenum disulfide, lead salt, metal powder and other
Solid matter is all preferably applied in the industry, and polytetrafluorethylepowder powder has been applied successfully to as lubricating additive
In lubricating grease and lubricating oil, the applicating history of molybdenum disulfide is even more that can trace back to the 17th century.The use form of solid lubricant
It can be simple substance, multiplexed combination can also be carried out because of a variety of different use purposes, form self-lubricating composite.Main application
Mix nanoparticles are added as additive and lubricate in the special dimensions such as machine driving, machining, aviation and electronics industry
Oil can improve the anti-wear and wear-resistant performance of lubricating oil.As A12O3-SiO2-MgO mixing nanometer additive has good dispersion steady
Qualitative, antifriction antiwear and self-repairability.Al2O3/SiO2 mixing nano particle in base oil mass fraction be 5% when, can
To significantly improve the anti-wear and wear-resistant performance of base oil.The research of scholar demonstrates mix nanoparticles can as lube oil additive
To improve the anti-wear and wear-resistant performance of lubricating oil.
