Description
Technical field
The invention belongs to inorganic nano composite material field, relate to the preparation method of the composite lubricated material of a kind of Graphene/zirconia nanopowder.
Background technology
2004, the AndreGeim professor of Univ Manchester UK and the computer MSR Information system of doctor KostyaNovoselov leader utilize a kind of simple micromechanics stripping method to obtain the Graphene of monoatomic layer thickness first, have led a revolution in this field thus.The performance of Graphene excellence and widely application prospect cause the unprecedented research enthusiasm of researchers.
Graphene is the two-dimension nano materials that thickness only has a carbon atom, is by sp
2hydbridized carbon atoms is arranged as cellular hexaplanar crystal, have high specific surface area, intensity, hardness, Young's modulus and strong unreactiveness and structural stability, the two-dimensional nanostructure of its uniqueness, excellent mechanics, process based prediction model make it in development high performance composite and functional materials, have huge application potential.In recent years, Graphene had more wide application prospect as new and effective lubricant in tribological field.Numerous investigator demonstrates Graphene good lubrication behavior (KandanurSS, RafieeMA, YavariF, etal. by Tribological Test from microcosmic and macro-scale
carbon 2012; 50:3178-83; EswaraiahV, SankaranarayananV, RamaprabhuS.
aCSApplMaterInterfaces , 2011; 3:4221-7; FengX, KwonS, ParkJY, etal.
aCSNano 2013; 7:1718-24; HunleyDP, FlynnTJ, DodsonT, etal.
physRevB 2013; 87:035417-21).In addition, the people such as Kim (LinLY, KimDE, KimWK, etal.
surfCoatTechnol 2011; Friction force microscope (FFM) 205:4864-9) is utilized to be studied multi-layer graphene micro-tribological behavior on a silicon substrate, although find that Graphene can reduce frictional force significantly, but when load increases to 5 μ N, there is obvious wear out failure in friction after 100 weeks in needle point.In addition, the people such as Berman (BermanD, ErdemirA.SumantAV.
carbon 2013; 59:167-75) have studied its macro-tribological properties by graphene dispersion to ethanol, result shows that the interpolation of Graphene can reduce the frictional coefficient of ethanol significantly, but loses efficacy immediately when load increases to 5N.As can be seen here, the Graphene with special size, low shearing force and surface energy can play friction-reducing and antiwear action well, namely can reduce frictional coefficient significantly and have higher antiwear property.But due to the thickness that Graphene is ultra-thin, there is inevitable defect and grain boundary in macroscopical sample, under larger load, its wear resistance has much room for improvement.In addition, the Intermolecular Forces that graphene film interlayer is stronger makes it easily produce to reunite and be insoluble in water and conventional organic solvent, thus as there is the problem of dispersion stabilization difference during lubricating oil additive, as the people such as Zhang Wei (Zhang Wei, Zhu Hongwei, Di Ze are superfine.
nanosecond science and technology 2011; 8:5-9) comparative study pure 150SN lubricating oil and the tribological property after with the addition of Graphene, find that pure 150SN oil can not complete friction-wear test under experimental conditions, and add the lubricating oil that massfraction is 0.001% Graphene, its frictional coefficient is comparatively stable, but when addition is increased to 0.005%, friction coefficient of lubricating oil becomes unstable.As can be seen here, these problems above-mentioned have had a strong impact on the widespread use of Graphene.
Zirconium white is a kind of important structure and function material, have that thermal conductivity is little, hardness and chemical stability and thermostability high, be widely used in the multiple fields such as pottery, refractory materials, machinery, photoelectricity, electronics, aerospace, biological and chemical.Based on zirconic above-mentioned excellent properties, the tribological property of investigator to zirconium white and matrix material thereof has carried out large quantity research.Such as, nano zircite joins in PAO-6 as lubricating oil additive by the people such as Battez, demonstrates zirconium oxide nano-particle suspension have good tribological property (BattezAH, GonzalezR, ViescaJL, etal. by rub(bing)test
wear , 2008; 265:422-8).The people such as the Zheng Shaohua zirconia/silica nano composite material that utilized Method in situ modification to prepare, the nano composite material of this surface modification has good diffusional stability in lubricating oil, thus improves tribological property (LiW, the ZhengSH of lubricating oil significantly, CaoBQ, etal.
jNanopartRes , 2011; 13:2129-37).
Metal oxide/graphene nanocomposite material can show the performance even characteristic of novelty of enhancing usually because of the synergistic effect between component; namely graphenic surface is carried on uniformly by inorganic nanoparticles; not only can solve the easy agglomeration of Graphene; the lubricity that grapheme material is good can be kept simultaneously; the high supporting capacity of Zirconium oxide can being made full use of again, making zirconium white/graphene nanometer composite as showing excellent tribological property during lubricating oil additive.But although researcher has carried out the preparation method of zirconium white/graphene complex, and be applied to different field, these preparation methods are only limitted to electrochemical deposition method and atomic layer deposition method.Recently, the people such as Wang Zonghua uses Na in water-Isopropanol Solvent
2s has prepared Graphene/zirconia composite as precipitation agent and reductive agent, but the method preparation process is more loaded down with trivial details.Up to the present, prepare zirconium white/graphene nanocomposite material by a step hydrothermal synthesis method and have no open report as the applied research of lubricating oil additive.
