Specific embodiment
Therefore, the present invention provides a kind of modified aluminium pigment, including following component：60~70wt% of flake aluminum, You Jirong
25~35wt% of the agent and 3~5wt% of composition formed with raw material graphene oxide and aliphatic acid.
Heretofore described flake aluminum is the flaky aluminium powder of microstate, is specially micron-stage sheet-like aluminium powder, this is micro-
Meter level flake aluminum is that fine spherical aluminum powder (micron-sized ball aluminum powder) is obtained through wet ball grinding.Such as cross 120 mesh sieves
The corresponding aluminium flake diameter of micro mist crosses the corresponding aluminium flake diameter of micro mist of 500 mesh sieves in 28 microns in 125 microns.
The organic solvent to play the role of scattered micron-stage sheet-like aluminium powder in aluminium pigment, because aluminium for active metal due to cannot be with moisture content
Contact, thus using organic solvent dispersion aluminium powder during wet ball grinding, such as corresponding organic solvent can be obtained by commercially available,
This is all well known to those skilled in the art content.Heretofore described graphene oxide is, for example, commercially available liquid oxidatively graphite
Alkene.A certain amount of aliphatic acid can be all included in modified aluminium pigment product in existing aluminium pigment and the present invention, aliphatic acid be given
Aluminium pigment plays lubrication and peptizaiton.
The present inventor is found through experiments that the graphene oxide directly adds in aluminium pigment, is dispersed in aluminium
In powder or addition cannot obtain modified aluminium pigment product of the present invention in organic solvent.And it can only be graphene oxide
Composition is first formed with fatty acid response, then the aluminium ball sphere of powder wears into the mistake of micron order aluminium flake powder in the micron-scale by said composition addition
Cheng Zhong and during being added kneading step after ball milling, the performance (such as brightness of pigment) of the aluminium pigment of gained
Just it is obviously improved.
In a kind of specific embodiment, the modified aluminium pigment is made of following three kinds of components, and flake aluminum 60~
70wt%, 25~35wt% of organic solvent and the 3~5wt% of composition.Modified aluminium pigment of the present invention can be included only
These three components certainly on the premise of the content of these three components is satisfied by requirement, can also add in the modified aluminium pigment
A certain amount of other auxiliary agents is added further to be modified it.
In a kind of specific embodiment, the modified aluminium pigment includes：65~67wt% of flake aluminum, organic solvent
30~32wt% and 3~the 5wt% of composition.
In a kind of specific embodiment, the mass ratio of raw material graphene oxide and aliphatic acid is in the composition
1.5~2.5：100.When graphene oxide dosage is too low, to the modified effect unobvious of aluminium pigment；And graphene oxide dosage mistake
Gao Shi, first, the totle drilling cost of aluminium pigment is excessively high, the other is may therefore bring the change of solid content and influence aluminium pigment
Performance.As a same reason, the composition typically constitutes from 3~5wt% in modified aluminium pigment, and composition levels are too high or too low all
Influence the performance of aluminium pigment.
In a kind of specific embodiment, the flake aluminum is micron-stage sheet-like aluminium powder, and the organic solvent is C9
Hydrocarbon organic solvent, the aliphatic acid are the long chain fatty acids of C12 or more.
In a kind of specific embodiment, the organic solvent is selected from C9 linear paraffins and C9 aromatic hydrocarbon, the long-chain
Aliphatic acid is selected from oleic acid, stearic acid and lauric acid.
In a kind of specific embodiment, the composition reacts for graphene oxide with aliphatic acid at 80~90 DEG C
And it obtains.
The present invention also provides a kind of preparation methods of modified aluminium pigment as described above, include the following steps,
Step A, the composition is prepared：Graphene oxide and aliphatic acid be stirred to react at 80~90 DEG C 5 it is small when more than
Obtain the composition；At such a temperature, with aliphatic acid chemistry occurs for graphene oxide (such as oxygen-containing functional group therein) instead
The composition should be generated.
Step B, by ball aluminum powder ball milling slabbing aluminium powder：It it is prepared by organic solvent, micron-size spherical aluminium powder and step A
Obtained composition adds in ball milling in ball mill, and ball aluminum powder ball milling slabbing aluminium powder is obtained after press filtration containing flake aluminum
Filter cake；
Step C, sieve classification：As add organic solvent by step B obtained by flake aluminum screening in filter cake be two-stage
The flake aluminum of more than different-diameter；
Step D, pressure filtration washing：The product organic solvent washing of step C and press filtration；
Step E, mediate：Filter cake, organic solvent, step A after pressure filtration washing in the step D compositions being prepared are sent
Enter to mediate in kneader and form the modified aluminium pigment.
Skilled person will appreciate that, the graphene oxide aliphatic acid composition in ball milling process might have part
It dissolves in organic solvent and enters in filtrate and cannot enter and timely enter in product, but the graphene oxide in kneading process
Aliphatic acid composition then can be fully synchronized into final modified aluminium pigment product.Therefore, in the kneading step of the present invention,
According to the component requirements of modified aluminium pigment product, fresh organic solvent and oxidation stone in filter cake obtained by step D needed for completion
Black alkene aliphatic acid composition can obtain target product.
In a kind of specific embodiment, sieve used includes 120 mesh sieves and 500 mesh sieves in sieve classification step.
Specifically, for example it is prepared via a method which to obtain a kind of modified aluminium pigment in the present invention.
The preparation of graphene oxide oleic acid composition：Oleic acid and graphene oxide are sequentially added in glass reaction kettle, is controlled
The final content of oxygenerating graphene in the composition is 2% or so.Mixer is opened, control rotating speed is at 200 revs/min or so.
It is shut down after temperature of reaction kettle is controlled when 80-90 degree, 24 is small and is cooled to room temperature, reaction product is released, when standing 24 is small.Upper strata
Clear liquid crosses 500 mesh screens to remove a small amount of impurity brought into raw material, and it is that graphene oxide content is left in 2wt% to collect filtrate
Right graphene oxide oleic acid composition.
Ball milling：In horizontal drum grinding machine, ground and be situated between as ball mill using the high-carbon steel ball of diameter 1.0mm, by 8 μm of ＜
The fine spherical aluminum powder that 10 μm of d50 ＜ is uniformly mixed by following weight ratio：Fine spherical aluminum powder: organic solvent: graphene oxide
Oleic acid composition=20~50: 80~200: 1~5, when rotating speed is small for 40 revs/min of lower ball millings 24, discharging, press filtration, filtrate is (main
To be organic solvent) recycling of ball milling process is returned to, filter cake enters subsequent processing；
Fine sieve classification；Filter cake enters sieve classification process, after filter cake addition organic solvent dissolving, first crosses 120 mesh sieves
(grain size be less than 125 microns), after 500 mesh sieves (grain size is less than 28 microns), will sieve materials at different levels (fineness degree it is different 120
Mesh and 500 mesh two-stage materials will be respectively formed the aluminium pigment product of different-grain diameter) filter press press filtration is used, drying, filtrate cycle is again
With filter cake enters subsequent processing；
Pressure filtration washing：It is washed with fresh organic solvent；Filtrate returns to screening process and recycles；
It mediates：Filter cake after washing enters kneading process and is surface-treated, and the purpose of kneading is so that in aluminium pigment
Three kinds of components are uniformly mixed, and play an important role of to be polished aluminium flake simultaneously.Concrete operations：Filter is sequentially added in kneader
