Further, grain graininess D100≤5um of the cobalt black colorant.
Further, the chromatic value of the cobalt black colorant is L*=16-18.5, a*=0.1-0.5, b*=0.05-0.25.
The present invention has the advantages that：
The present invention obtains ideal colorant component prescription range and colorant preparation method, the cobalt black of gained by largely testing
Colorant color development is full, pure color, magnetic low.
Specific implementation mode
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
A kind of ceramic ink cobalt black colorant is made according to weight percent of following raw material：Co3O4 35%-45%、NiO
15%-20%、Fe2O3 8%-15%、Cr2O3 20%-30%。
The present invention is with Co3O4、NiO、Fe2O3And Cr2O3It is brilliant using Solid phase synthesis Co-Ni-Fe-Cr systems point for raw material
Stone black pigment.In existing cobalt black colorant, Fe2O3Additive amount often beyond 15%.Inventor is in practice, it has been found that Fe2O3
Additive amount when being more than 15%, the magnetism of the cobalt black colorant of preparation is excessive, and this cobalt black colorant is used to prepare ceramic ink in ink-jet
It can lead to bracing wire, drop ink when being used on machine.Inventor is by numerous studies discovery, Fe2O3Additive amount be no more than 15%,
Pass through Reasonable Regulation And Control Co simultaneously3O4, NiO and Cr2O3Usage ratio, so as to get cobalt black colorant crystal structure in cobalt chromium
Based on spinelle, nickel chromium triangle spinelle, supplemented by ferro-cobalt spinelle, NiFe_2O_4 spinel, cobalt black colorant magnetism can substantially reduced
While, and can ensure that cobalt black colorant color development is full, pure color.
Before, think the black pigment of pure color always in the industry to use additive amount to be more than 15% Fe2O3, however this
Invention is by Reasonable Regulation And Control formula, in Fe2O3Additive amount be 8-15% in the case of still obtain the black color of pure color
Material.
It should be noted that the grain graininess D100 ＜ 10um of each raw material.
The present invention also provides the above-mentioned ceramic ink preparation methods of cobalt black colorant, include the following steps：
S1. following raw material is weighed respectively according to weight percent：Co3O4 35%-45%、NiO 15%-20%、Fe2O3 8%-15%、
Cr2O320%-30%, wherein the grain graininess D100 ＜ 10um of each raw material；
S2. the raw material that step S1 is weighed is uniformly mixed and obtains reactant, reactant and high alumina ballstone, solvent are placed in ball mill
Middle carry out ball-milling treatment so that grain graininess D100≤8um of reactant；
Wherein, the reactant, high alumina ballstone, solvent mass ratio be 100:（500-550）:（60-70）；It is highly preferred that institute
State reactant, high alumina ballstone, solvent mass ratio be 100:525:65.
The solvent is preferably water, but not limited to this.
For the present invention in ball milling, the rotation of ball mill drives high alumina ballstone to rise to certain altitude, high alumina ballstone hardness
Height, density are big, preferably hit reactant using the eccentricity and gravitation energy of high alumina ballstone, grinding, improve grinding efficiency.
Specific process parameter of the present invention to ball-milling treatment（Such as rotating speed, Ball-milling Time etc.）It is not particularly limited, as long as
So that grain graininess≤8um of reactant.
S3. processing is dried in reactant；
S4. the obtained materials of step S3 are calcined, calcination temperature is 1280 DEG C -1320 DEG C, keeps the temperature 2-3 hours；
S5. after calcined product being carried out break process, then with ball mill ultra fine is carried out, obtains cobalt black colorant.
Grain graininess D100≤5um of the cobalt black colorant.
The chromatic value of the cobalt black colorant is L*=16-18.5, a*=0.1-0.5, b*=0.05-0.25.
In step S2 and S5, used ball mill is preferably planetary ball mill, and inner liner of bowl mill is ceramic-lined.In order to
It prevents iron filings powder from entering in colorant and increases colorant magnetism, the present invention is handled colorant by ball mill ball milling, ball milling
Machine liner is ceramic-lined, is ground with high alumina ballstone, and can avoid this process influences the magnetism of colorant.
Cobalt black colorant needed when preparing ceramic ink by nanometer sand mill be ground to grain graininess D100 be less than 1um,
The structure of ceramic ink cobalt black colorant colorant in process of lapping can change a lot, and colorant grinding is thinner, in colorant
The substance that portion has neither part nor lot in reaction will discharge more, influence the saturation degree of colorant color development.The particle of traditional glaze cobalt black colorant
Granularity D100 can lead to color in 45um or so, thus when traditional cobalt black colorant is used to prepare ceramic ink in process of lapping
Expect that great changes will take place for structure, and then influences the degree of staining of colorant.Inventor is having found during the test, ultra-fine by selecting
Raw material, make the grain graininess D100 ＜ 10um of each raw material, while raw material mixing is carried out by way of wet ball grinding, this can be with
So that raw material is uniformly mixed, can be come into full contact between various raw materials, the particle size distribution of the cobalt black colorant product of synthesis is narrow,
It is not easy to reunite, in the process of lapping for preparing ceramic ink, color development and color development stability are good.
