Description
Technical field
The present invention relates to a kind of method and product that utilizes leather-making mud to prepare black ceramic colorant, belong to colorant preparing technical field.
Background technology
Black ceramic colorant is a kind of colorant very important in finishing material, and black glaze is with the extremely people's favor of its pure, dignified decorative effect.What generally prepare black pigment employing is coloring of crystal: the metal oxides such as chromium, iron, manganese, nickel, copper, cobalt form isomorphous mixed type spinel crystal.The oxidated cobalt price of black ceramic colorant price and remaining high, has to a certain degree limited production in enormous quantities and the application of black pigment.At present existing research and utilization chromium residue is prepared the method for black ceramic colorant base for: the industrial residue chromium mud at 950-1050 ℃ after calcining, ferric oxide and chromic oxide mixing, 1180-1250 ℃ calcine 1 hour, pulverize to obtain product.But the method, chromic oxide is not replaced by industrial residue chromium mud completely, and its cost is still higher, and blackness is lower.
Summary of the invention
A goal of the invention of the present invention is: provide a kind of and can further reduce production costs, product can base with also can glaze with and the method for preparing black ceramic colorant of quality better.
Another goal of the invention of object of the present invention is: provide a kind of aforesaid method prepared black ceramic colorant.
Leather-making mud is the solid waste obtaining after chrome tanned leather waste water alkaline chemical precipitation, is wherein rich in chromium; A kind of industrial residue chromium mud.In order further to reduce production costs, first contriver expects replacing chromic oxide as raw material completely with leather-making mud.But experiment is found, with leather-making mud, replace chromic oxide as raw material completely, adopt existing method lignin-sludge, utilize it to prepare black ceramic colorant and have following problem: blackness is lower, color is impure, unstable properties under hot conditions, tinctorial property is poor and washing use procedure in there is the problem of a large amount of Cr6+ strippings.
Contriver tests discovery after deliberation: after leather-making mud washing is dry, replace chromic oxide directly to use as raw material completely, can prepare can base with also can glaze with and the black ceramic colorant that obviously improves of blackness; So, simplify preparation section, shortened the production cycle, further reduced production cost.But there is unstable properties under hot conditions in this black ceramic colorant, tinctorial property is poor and wash the problem that has Cr6+ stripping in use procedure.And leather-making mud is used through be re-used as raw material after " calcining; then ball milling, washing, dry " this pretreatment operation under nonoxidizing atmosphere, prepared black ceramic colorant, its use temperature improves, tinctorial property improves, consumption reduces, and colorant can not exist a large amount of Cr6+ strippings in washing and use procedure.
The technical scheme that the present invention takes is:
Utilize leather-making mud to prepare a method for black ceramic colorant, raw material is through pulverizing, calcine to obtain product; Its improvements are: with the dried leather-making mud of washing, replace chromic oxide as raw material,
Or replace chromic oxide as raw material after leather-making mud pre-treatment; Described pre-treatment: calcine under nonoxidizing atmosphere, then ball milling, washing, dry.
Experimental studies have found that: the variation of leather-making mud pretreatment condition, has a significant effect to the colourimetric number of black ceramic colorant, pulverizing complexity.
After leather-making mud is processed under nonoxidizing atmosphere below 1050 ℃, gained calcined material is easily pulverized; But, using this calcined material to use as raw material, prepared black ceramic raw material, its blackness is lower, black is impure, partially red.
After leather-making mud is processed under more than 1300 ℃ nonoxidizing atmosphere, gained calcined material is difficult to pulverize; Usining this calcined material uses as raw material, prepared black ceramic raw material, and its blackness is low, black is impure, partially reddish-brown.
After leather-making mud is processed under 1100-1300 ℃ of nonoxidizing atmosphere, gained calcined material is easily pulverized; Usining this calcined material uses as raw material, prepared black ceramic raw material, and its blackness is high, black is pure.
So, aforesaid method, preferred, described pre-treatment: preferably process 30 ~ 180min under 1100-1300 ℃ of nonoxidizing atmosphere.Aforesaid method, highly preferred pre-treatment is: process 60min for 1250 ℃.
In aforesaid method, the pulverizing of raw material, calcining adopt conventional processing means, and the present invention adopts: pulverized 300 orders, calcining temperature is 900-1300 ℃, and calcination time is 30-180min.
Aforesaid method, raw materials usedly also comprises metal oxide that determine according to black ceramic colorant crystal system to be prepared, beyond chromic oxide; The consumption of described leather-making mud is 10 ~ 60%.
Prepare the needed raw material of different crystal system black ceramic colorant different, at present, without cobalt black look ceramic pigment crystal system, comprise: Cr-Fe system, Ni-Cr-Fe system, Ni-Cr-Fe-Cu system, Ni-Cr-Fe-Mn system, the systems such as Ni-Cr-Fe-Mn-Cu.So, those skilled in the art can according to the crystal system of black ceramic colorant to be prepared determine select which kind of or which plant metal oxide and consumption thereof.So, aforesaid method, described metal oxide is one or more in nickel sesquioxide, cupric oxide, Manganse Dioxide, manganic oxide, manganous carbonate, ferrous sulfate, nickel protoxide and rare earth oxide.
Aforesaid method, described raw material is preferably:
25-70% leather-making mud, 30-75% ferric oxide;
Or, 30-50% leather-making mud, 20-50% ferric oxide, 10-30% nickel sesquioxide;
Or, 45-55% leather-making mud, 20% ferric oxide, 15-20% nickel sesquioxide, 10-15% cupric oxide;
Or, 30-60% leather-making mud, 20-40% ferric oxide, 5-25% nickel sesquioxide, 5-20% manganic oxide;
Or, 30-50% leather-making mud, 15-44% ferric oxide, 15-30% nickel sesquioxide, 1-10% manganic oxide, 10-30% cupric oxide.Better according to the quality of the prepared black ceramic colorant of this usage ratio.
Aforesaid method is different to the improvement degree of the black ceramic colorant quality of different crystal system; Wherein, maximum to the improvement degree of the mixed type spinel crystal black ceramic toner performance of Ni-Cr-Fe-Cu crystal system, the Ni-Cr-Fe-Cu crystal system black ceramic toner performance obtaining is best; Its raw material is: leather-making mud 45-55%, ferric oxide 20%, cupric oxide 10-15%, 15-20% nickel sesquioxide.Optimal proportion is: leather-making mud 50%, ferric oxide 20%, cupric oxide 15%, 15% nickel sesquioxide.
Raw material is different, calcining temperature, soaking time difference; Those skilled in the art can be according to selected raw material and consumption, corresponding calcining temperature and the time of adjusting while preparing black ceramic colorant.
A black ceramic colorant, adopts above-mentioned any one method to be prepared from.
Beneficial effect
