Description
Technical field
The invention belongs to ceramic pigment technical fields more particularly to a kind of ceramic black pigment and preparation method thereof.
Background technique
Traditional ceramics are with black pigment mainly with coloured and black such as iron (Fe), chromium (Cr), nickel (Ni) manganese (Mn), copper (Cu)
Metal oxide is raw material.As the staple commodities prices such as coloured and ferrous material climb up and up, this black pigment because
Price causes large batch of production and application to be restricted, and researching and developing cheap and hair color effect, good black pigment gesture exists
It must go.
A large amount of stainless steel slag is all discharged in China every year, since stainless steel slag is rich in heavy metal, such as handles not in time,
Great threat can be caused to environment and human health, while also result in the waste of useful resources.In view of stainless steel slag contains
The elements such as iron, chromium, nickel, manganese, it is close with the composition of raw material of conventionally produced black pigment, therefore many research trials will not
Rust steel steel slag to reduce the production cost of black pigment, while reducing the ambient wind of stainless steel slag for making black pigment
Danger.The prior art, which mainly matches steel slag, obtains black pigment with chromium oxide, copper oxide, iron oxide and nickel oxide mixed calcining.No
Crossing reduces the ingredient of blackness, existing scheme in view of typically containing aluminium oxide, magnesia, titanium dioxide, calcium oxide etc. in steel slag
The content of middle steel slag generally only has 50~60%, and needs that expensive nickel oxide is added, while not accounting in chromium residue not
The metal problem of oxidation, thus there are utilization rate of steel slag it is low, cost is high, coloured light is insufficient the problems such as.
Summary of the invention
Based on this, the present invention provides a kind of ceramic black pigment, which uses stainless steel slag, and
With pure black, dispersion degree is big, strong coloring force, light resistance and good weatherability, while manufacturing cost is lower.
Ceramic black pigment of the present invention includes following components according to mass percent meter:
Compared with the existing technology, the present invention mixes the stainless steel that mass percent is up to 80% or more in black pigment
Steel slag includes Fe in stainless steel slag2O3、Cr2O3、Al2O3、MnO2、TiO2And the ingredients such as MgO, Fe2O3、Cr2O3、Al2O3、
MnO2、TiO2, the ingredients such as NiO and MgO can be formed after sintering present black spinel structure.Again with 4~5%Fe2O3With 3
~4%Cr2O3As supplement, it can be ensured that the black depth and stability of colorant, while the CoO of addition 1~2% is black to increase
The distinct degree of color.
Further, the multiple elements design sintering aid includes B2O3、Bi2O3、TiO2、CuO、Ir2O3。B2O3、Bi2O3Have with CuO
There is lower fusing point, wherein B2O3To melt be 450 DEG C, Bi2O3Fusing point be 820 DEG C, the fusing point of CuO is 1026 DEG C.According to congruent melting
Principle, component is more, and eutectic temperature is lower, then the temperature for being fused into liquid phase is lower, therefore after addition multiple elements design sintering aid,
The firing temperature of black pigment can be significantly reduced.And B2O3It volatilizees at 800 DEG C or more, will not influence the performance of black pigment.
Meanwhile B2O3、Bi2O3、TiO2、CuO、Ir2O3The multiple elements design sintering aid of composition can also improve the bright and new degree of black pigment, mention
The quality of high black pigment.
Further, the B2O3、Bi2O3、TiO2、CuO、Ir2O3Mass ratio is 6:4:5:4:1.
Further, the composite grinding aids include sodium lignin sulfonate, gypsum and coke.Use stainless steel slag as original
Material needs to be ground to 300 mesh or more when producing black pigment, since stainless steel slag contains fe-cr-ni alloy etc. firmly
Spend high ingredient, therefore the process of lapping generally consumes energy high, low efficiency.The present invention is by being added sodium lignin sulfonate, gypsum
Grinding efficiency can be effectively improved as grinding aid with coke.Wherein sodium lignin sulfonate is a kind of anionic surfactant,
Its Anion-adsorption on pigment granules surface, can not only reduce pigment granules surface can, can also prevent pigment granules it
Between reunion, improve the dispersibility and sliding property of pigment granules.And coke and gypsum can then form the package on pigment granules surface
Film makes surface reach saturation state, avoids attracting each other and coheres into agglomerate, improves the mobility of colorant.Sodium lignin sulfonate, stone
It is mutually cooperateed between cream and coke three, further increases grinding-aid effect, to reach reduction grinding energy consumption, improve grinding efficiency
Purpose.
Further, the sodium lignin sulfonate, gypsum and coke quality ratio are 2:1:1.
The present invention also provides the preparation methods of above-mentioned ceramic black pigment, comprising the following steps:
(1) stainless steel slag is calcined, Fe is then added2O3、Cr2O3, CoO and composite grinding aids ground, then carry out
Oxidation processes；
(2) it successively roasted, be crushed, fine grinding after mixing the material after oxidation processes with multiple elements design sintering aid
Obtain black pigment.
Further, the stainless steel slag, Fe2O3、Cr2O3, CoO, composite grinding aids and multiple elements design sintering aid quality
Percentage is followed successively by 80~85%, 4~5%, 3~4%, 1~2%, 2~3%, 5~7%.
Further, step (1) calcination temperature is 1100~1200 DEG C, and calcination time is 1~2h.
Further, step (1) oxidation treatment method is that material is exposed to 39~48h in air.By that will grind
Good material is exposed in air, can make the fully oxidized metal oxide at color development of unoxidized metal in stainless steel slag.
Further, step (2) maturing temperature is 1050~1100 DEG C, and calcining time is 7~8h.
Further, step (2) fine mill size is not less than 300 mesh, and sieve residue is not more than 5%.
Specific embodiment
The present invention passes through scientific allocation stainless steel slag, Fe2O3、Cr2O3, CoO, composite grinding aids and multiple elements design help burning
Accounting of the stainless steel slag in black pigment is greatly improved in the ratio of agent, at the same guarantee black pigment black depth,
Stability, distinct degree, and the maturing temperature in manufacturing process is reduced, it reduces energy consumption, improve efficiency.Below by way of specific reality
Example is applied to illustrate technical solution of the present invention.
Ceramics of the present invention are prepared by the following method to obtain with black pigment:
(1) stainless steel slag is calcined, Fe is then added2O3、Cr2O3, CoO and composite grinding aids ground, then carry out
