Description
Technical field
The present invention relates to a kind of composite material, in particular to a kind of graphene/aluminum composite material.
Background technique
It is big due to hanging span in the air, overhead high voltage transmission line other than the electric conductivity to leader cable there are certain requirements,
The intensity of leader cable also there are certain requirements.Domestic and international more common overhead high voltage electricity transmission conductive wire includes copper conductor and aluminium at present
Conducting wire.Compared with aluminum conductor, the good conductivity of copper conductor, intensity height.But the higher cost of copper conductor, and copper belongs to strategy
Resource, and bauxite resource is abundant, it is widely distributed, it is at low cost.Although almost 90% aluminium used above is compound for some places transmission line of electricity
Material conducting wire, but the application amount of some local aluminum composite conductors is less than 1%.Therefore, in order to reduce cost, it is necessary to add
The development and application of big overhead high voltage power transmission aluminum conductor cable.
The aluminum conductor cable material of industrial application includes fine aluminium and aluminium composite material at present, but the intensity of the two and is led
Electrical matching is all lower.The good conductivity of fine aluminium, but intensity is lower.Existing aluminium composite material on the basis of fine aluminium,
It adds made from the alloying elements such as Mg, Si, composite material obtained but brings electric conductivity while improving the strength of materials
It reduces.In recent years, as the suspension span of overhead high voltage transmission line is increasing, the performance of aluminum conductor cable is proposed higher
Requirement.For this purpose, developing, a kind of intensity is high, aluminum conductor cable of good conductivity just seems very necessary.
Graphene is a kind of two-dimension nano materials being made of carbon atom, and in individual layer laminated structure, (thickness is only several receive
Rice).Due to its unique bi-dimensional cellular crystal structure and high bond strength, graphene is the specific strength in the world being currently known
Highest, most hard nano material, breaking strength are up to 130Gpa.(Changgu Lee, Xiaoding Wei, Jeffrey
W.Kysar, James Hone) et al. delivered on (Science, Vol.321, issue 18, July 2008,385-388)
About " measurement of single-layer graphene retractility and inherent strength " (Measurement of the elastic properties
and intrinsic strength on monolayer graphene).Importantly, graphene or world conductivity
Highest material (resistivity only about 10-8Ω m), about the 100 of copper times.Therefore, the high-intensitive and good of graphene is utilized
Electric conductivity, and it is compound with fine aluminium or aluminium composite material, it is prepared into graphene/aluminum composite material, it is expected to for improving aluminium electricity
The intensity and electric conductivity of cable, match the mechanical property of aluminum conductor and electric property preferably.
Based on analysis described above, it is desirable to provide a kind of preparation process obtains graphene/aluminum composite material, and realizes stone
Evenly dispersed and graphene/aluminum high quality interface of the black alkene in aluminum substrate combines.The preparation of aluminum matrix composite at present
Method is mainly melt casting and powder metallurgic method.If graphene/aluminum composite material is prepared using conventional melt casting,
Since the two density variation is big, graphene be difficult it is evenly dispersed inside molten aluminum, in addition, the two in material preparation process also
High-temperature interface reaction may occur, generate Al4C3Brittlement phase deteriorates material property.And use powder metallurgic method, then it can make graphite
Alkene nanometer sheet and aluminium composite material powder realize uniform mixing at room temperature, then prepare graphite by subsequent pressure processing
Alkene enhances aluminum-base composite block materials, and conventional melt casting bring high-temperature interface is inhibited to react to the maximum extent.
However, facts proved that, since graphene nanometer sheet and aluminium composite material powder (atomization) are in pattern, size and density
Etc. all there is very big difference (being shown in Table 1), the graphite that both causes the compatibility in Material cladding very poor, nonmetallic
The aluminium of alkene and metal is hardly formed good interface cohesion under powder metallurgical technique.(BARTOLUCCI S F,
PARAS J, RAFIEE M A, et al.) et al. [[J] .Material Science and Engineering A, 2011,
528:7933-7937.)] graphene-aluminium nano-composition " Graphene-aluminum is disclosed on magazine
nanocomposites".And for aluminum matrix composite, distribution of the reinforced phase in aluminum substrate whether uniformly, reinforced phase
Whether whether generation reunion, interface cohesion are close, directly decide the superiority and inferiority of composite property.Therefore, graphene is in aluminium base
How evenly dispersed in body is realized and the high quality interface of graphene/aluminum is combined and how to be obtained, and is to prepare graphene/aluminum
Composite material needs the key technology broken through.
The difference of table 1 graphene nanometer sheet and aluminium composite material powder
The low temperature ball-milled powder metallurgical technology occurred in recent years is compared with traditional powder metallurgic method, is improving reinforced phase
There is apparent advantage in terms of dispersibility and interface cohesion.The mechanical ball mill that conventional powder metallurgical technique uses only by reinforced phase and
The powder of matrix phase is uniformly mixed together, and is difficult in mechanical milling process just to form interface cohesion between powder；And low temperature ball milling
Powder metallurgy rule is that inertia cryogenic medias such as liquid nitrogen (or liquid argons), unique ball milling are introduced in tradition machinery mechanical milling process
Environment (low temperature and inert media) makes it have plurality of advantages.Pertinent literature shows (YE J C, HE J H, SCHOENUNG J
M.Cryomilling for the fabrication of a particulate B4C reinforced Al
Nanocomposite:Part I.Effects of process conditions on structure [J]
.Metallurgical and Materials Transaction A, 2006,37A:3099-3109.), ceramic particle/aluminium is mixed
It closes powder and passes through low temperature ball milling, while obtaining nanocrystalline aluminum substrate, it is evenly dispersed in aluminium to realize ceramic particle, and also
Ceramic particle can be coated on inside aluminium, form the interface cohesion of high quality.Therefore, can attempt by low temperature ball grinding technique come
Realize the graphene/aluminum interface that is uniformly distributed, obtains high quality of the graphene nanometer sheet in aluminium.
Facts proved that high quality score graphene (1.0%) not only may be implemented using low temperature ball-milled powder metallurgy method
Effectively addition, but also interface cohesion situation (the LI J of dispersibility and graphene/aluminum of the graphene in aluminium can be substantially improved

L.Microstructure and tensile properties of bulk nanostructured aluminum/
graphene composites prepared via cryomilling[J].Materials Science and
Engineering A, 2015,626:400-405).However, though graphene can be realized in aluminium using low temperature ball-milled powder metallurgy method
In evenly dispersed and graphene/aluminum interface cohesion improvement, still, this method complex process, higher cost, be not suitable for
In the large-scale engineering application of low value-added field (such as electric appliance, cable etc.).
To realize that the large-scale production of aluminum conductor cable product is applied and adapted to the engineering of graphene/aluminum composite material,
It just must be using the method for melting casting.It, can be but if be added directly into graphene is without any processing in molten aluminum
Serious defect (stomata, graphene reunion etc.) is observed in finally obtained ingot casting, deteriorates material property.
