Description
Technical field
The present invention relates to be widely used in the exploitation based on the water-base lubricant of carbon nanotube of the lubrication in the mechanical workout, belong to nanometer science and technology in field that mechanical field is used.
Background technology
In the manufacturing field of 21 century, the utilization of resources is reasonable, discarded less, environmental pollution is little, can carry out eucyclic " green manufacture technology " will become main development trend.Raw material of the present invention is cheap and easy to get, and nontoxic, harmless, non-corrosiveness belong to environmental friendly product, and be easy to large-scale industrial production, gives full play to advantages such as water base lubricant is efficient, energy-conservation.20th century, nano material was also like a raging fire as the research of lubricating oil additive along with the continuous understanding of people to nano material.Nanoparticle has more excellent antiwear and friction reduction property than traditional slip additive.Raw material of the present invention is cheap and easy to get, and nontoxic, harmless, non-corrosiveness belong to environmental friendly product, are easy to large-scale industrial production, gives full play to advantages such as water base lubricant is efficient, energy-conservation.
1991, Japanese scientist Iijima found multi-walled carbon nano-tubes (MWNT) first, and diameter is 4-30nm.Single Walled Carbon Nanotube also was found (SWNT) in 1993, and diameter is from 0.4nm to 3-4nm, and length is several microns even longer.Carbon nanotube has unique machinery and chemical property, and having a wide range of applications in fields such as machinery, electrochemistry, the energy has caused domestic and international a lot of scholar's interest.Carbon nanotube has good heat conductivity, ductility, chemical stability, and the patent of using as lubricating oil additive also seldom.Because carbon nanotube is that diameter is between 10～100nm, water-fast nano material, carbon nanotube is joined in the aqueous solution, the surface of carbon nanotube and interfacial effect and small-size effect have limited its application in water, and the suspension stability of carbon nanotube in water is the key that makes full use of the carbon nanotube excellent properties.Be easy to the sinking of condensing in the aqueous solution, in order to improve its dispersion stabilization in water, the present invention carries out surface modification to carbon nanotube.Chemically modified can make carbon nanotube coat group of different nature, change its interfacial state and character, make it to become polar surfaces by original apolar surfaces, and because the spatial masking effect between adsorption layer, carbon nanotube is difficult to take place collision mutually, assembles and precipitation, thereby stable dispersion is applied to the oiling system of tradition machinery in water-based lubricating liquid.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of preparation method of the high-efficiency water-base lubricating fluid based on carbon nanotube, have good load and antiwear and friction reduction property, can improve the water base lubricant oilness, can be used as the working fluid of metal cutting etc.
Technical scheme: the preparation method of the high-efficiency water-base lubricating fluid based on carbon nanotube of the present invention comprises:
This method is at first carried out the wetting ability pre-treatment to carbon nanotube, and in conjunction with yellow soda ash, sodium sulfonate dispersion agent and defoamer preparation, its processing step is divided into then:
1) with the original carbon nanotube of the meteorological growth of chemistry at the vitriol oil and concentrated nitric acid by in 3: 1 blended mixed solutions, 100 ℃ were refluxed 8 hours, then with deionized water repeatedly clean, the hydrophilic carbon nanotube of centrifugal acquisition;
2) carbon nanotube after the previous step hydrophilic treatment, dispersion medium and the auxiliary agent volume ratio by 1: 100000: 10 is mixed;
3) carbon nanotube under promoter effect in water dispersion medium ultra-sonic dispersion, centrifuging and taking upper strata carbon nanotube stable dispersion solution; Promptly make high-efficiency water-base lubricating fluid based on carbon nanotube.
Described dispersion medium is a deionized water.
Described auxiliary agent is one or both the combination in sodium laurylsulfonate, Sodium dodecylbenzene sulfonate or the sodium laurylsulfonate.
Beneficial effect:, reduce and excessively rub, improve supporting capacity because the carbon nanotube diameter low etc. is expected to fill at the friction microcell for a short time, active, absorption, stop the direct contact on pair of friction components surface; And the water soluble surfactant active plays anti-attrition, wear-resistant effect by forming friction film etc. with matrix at friction surface under friction condition, therefore, have load height, advantage that the anti-attrition performance is good, can improve the water base lubricant oilness, can be used as the working fluid of metal cutting etc.
Estimate of the present invention respectively based on antiwear and friction reduction property and supporting capacity under the carbon nanotube water base lubricant (Pb value) (four ball methods) by the GB3142282 method.At four-ball friction and wear test machine, investigation is based on the friction and wear behavior of the water based lubrication additive of carbon nanotube, the frictional coefficient of whole experiment is write down the antifriction performance of statistics sign lubricating fluid with data collecting system, with opticmicroscope wear scar diameter is measured the antifriction performance of lubricating fluid, have good antiwear and friction reduction property.
