Description
Technical field
The invention belongs to ceramic pigment technical field, and in particular to a kind of zirconium silicate parcel nano carbon microsphere ceramic black material
Preparation method.
Background technology
Ceramic pigment has far-reaching extensively as a kind of important additive indispensable in china industry, colouring agent
Using.Color generation property, the physical and chemical performance of ceramic pigment directly affect the quality of production of ceramic.At present, ceramic pigment is pressed
Temperature in use can be divided into low form and high temperature modification.High temperature modification colorant temperature in use has widely more than 1000 DEG C
Application prospect, more excellent color generation property.But in numerous ceramic pigments, the accounting of low form colorant is significantly larger than high temperature modification color
Material.Therefore the high temperature modification colorant important in inhibiting that encapsulation ratio is high, colour generation is pure and stable is developed.
Zirconium silicate wraps up carbon black as the ceramics parcel black material of high temperature modification, has universality to the glaze of different systems,
And will not be influenceed by firing atmosphere, have than traditional spinel-type black material preferably colour stability, widely application.
In the prior art, wrappage --- carbon black is usually to choose acetylene carbon black, high-carbon black pigment etc. as present-color material.These carbon
Black hydrophily is poor, it is impossible to preferably keep dispersiveness in the solution.More importantly they do not have surface-active, subsequently
Parcel be almost a kind of random parcel mechanism.Therefore the encapsulation ratio of existing zirconium silicate parcel black pigment is relatively low, colour generation not
Good, colourity is partially grey（Colorant brightness value L* ＞ 30）.
The content of the invention
The mesh of the present invention is to be to overcome that current zirconium silicate parcel black pigment encapsulation ratio is relatively low, colour generation is not good, and colourity is inclined
There is provided the preparation method that a kind of zirconium silicate wraps up nano carbon microsphere ceramic black material for the deficiency of ash.
The present invention is achieved by the following technical programs：A kind of zirconium silicate wraps up the preparation of nano carbon microsphere ceramic black material
Method, it is characterised in that comprise the following steps：
The first step：Prepare nano carbon microsphere powder
30~60g of biomass material is added in 350ml water, after stirring, solution is poured into reactor, then will be anti-
Answer kettle to be placed in 6~10h of hydro-thermal reaction in 160~200 DEG C of baking oven, then and by reacted solution suction filtration and with absolute ethyl alcohol go
Ionized water cleans three acquisition carbon ball particles, then carbon ball particle is dispersed in 1mol/L alkaline solution stirred at 30~70 DEG C
1~6h is mixed, then cleans with deionized water the pH value of alkaline solution to 7, most afterwards through being dried to obtain nano carbon microsphere powder；
Second step：Prepare carbon ball suspension
Nano carbon microsphere powder is added in the ammoniacal liquor that mass percent concentration is 15~30%, carbon is dispersed under ultrasonication
Ball suspension, the mass percent of the nano carbon microsphere powder and ammoniacal liquor is 1:100~300；
3rd step：Prepare silicon zirconium mixed solution
One kind in tetraethyl orthosilicate, silicon tetrachloride, sodium metasilicate is dissolved in ethanol solution, 1~6h is stirred at room temperature, so
The one kind added in the solution in zirconium oxychloride, zirconyl nitrate, zirconium iso-propoxide, zirconium chloride afterwards, continues to stir 1~6h under normal temperature,
The Zr4+With Si4+Mol ratio be 1:1~2, ethanol in ethanol solution:The volume ratio of water is 1:1；
4th step：Prepare precursor powder
Silicon zirconium mixed solution by volume 3~6 after 3rd step is stirred:1, which is added dropwise to carbon ball made from second step, suspends
In liquid, 2~6h, subsequent 2~6h of cooling and aging are stirred at 40~80 DEG C, the suspension that presoma wraps up carbon ball is obtained, then will
The suspension of presoma parcel carbon ball, which is centrifuged, obtains presoma, after 80 DEG C are dried, you can obtain precursor
End；
5th step：Prepare parcel black material
Precursor powder made from 4th step is further ground, crossed after 60~200 mesh sieves, is added according to 0.5~5% mass ratio
Mineralizer, is well mixed, is subsequently placed into crucible, under argon gas atmosphere protection, is warming up to 950~1050 DEG C, and calcining 90~
Burnt colorant powder, is put into 900 DEG C of electric furnace and is heat-treated 1h under oxidizing atmosphere, go by 200min after natural cooling
After uncoated carbon ball powder, you can obtain the nano carbon microsphere ceramic black material of zirconium silicate parcel.
The chromatic value of the nano carbon microsphere ceramic black material of zirconium silicate parcel is made from 5th step：A*=5.1~5.8；
B*=- 0.7~0.1；L*=27~29.5.
Mineralizer in 5th step is one kind in sodium fluoride, magnesium fluoride, lithium fluoride.
The volume of reactor is 400ml in the first step.
The time of ultrasonication is 30min in the second step.
The time is centrifuged in 4th step for 10~20min.
The nano carbon microsphere that the present invention is prepared using biomass material by hydro-thermal method substitutes traditional carbon source, utilizes carbon ball surface
Rich oxygen-containing functional group and residing negative potential state add its hydrophily, enhance the dispersiveness of carbon source.And pass through
Simple soda acid processing is carried out to carbon ball can realize the regulation to integument thickness and control.Carbon ball surface by alkali process
With higher negative potential, the thickness of hydrophilic layer also accordingly increases.
Correspondingly integument thickness can also increase, therefore carbon ball can be protected preferably at high temperature.Pass through carbon ball sheet
Zr has efficiently been adsorbed in the electrostatic adsorption of body4+、Si4+, zirconium silicate presoma is tightly wrapped in carbon ball.
Under mineralizer effect, the ceramic black material that zirconium silicate wraps up nano carbon microsphere is made after high-temperature calcination.In reality
During testing by the addition of biomass material, hydrothermal temperature, hydro-thermal time and silicon zirconium ratio, presoma mixing time,
The optimization and control of the condition such as mineralizer species and consumption selection, calcining system, obtain that colorant encapsulation ratio is higher, integument more
The coated carbon ball black material better than prior art is presented in densification, colourity.The black material color development of synthesis is pure, uniform particle sizes, property
Can be stable, it can be used in all kinds of refractory ceramics glaze, with higher economic value, therefore with before wide market
Scape.
