Description

Low temperature ceramic color without lead on glaze
Technical field
The present invention relates to a kind of low temperature ceramic color without lead on glaze, belong to the beramic color technical field.
Background technology
Ceramic trailing the most widely is over-glaze decoration.Over-glaze decoration is to use under 750 ℃～850 ℃ low temperature, thus add 30～50% plumbous oxide in traditional production technique, so that the roasting burning temperature range of colour on glazed ceramics is wide and color development is pure.But plumbous in the production and use of beramic color, caused that to the pollution of atmosphere, water resources with to the injury of human body common people pay close attention to, the plumbous stripping on meal, kitchenware surface potential carcinogenic substance especially especially constitutes a threat to people's health.In order to reduce and to eradicate plumbous murder by poisoning, unremitting effort is being done always by the scientific research and the production department of ceramic decoration industry both at home and abroad.
In English Patent CB2250285A, invented a kind of unleaded ceramic pigment flux, its formation (mot%): SiO 2: 50～70, Bi 2O 3: 10～40 Al 2O 3: 3～30, B 2O 3: 0～15, Li 2O:0～10, Na 2O:0～10, K 2O:0～10, MgO:0～5, CaO:0～10, ZnO:0～10, ZrO 2: 0～5, TiO 2: 0～5, SnO 2: 0～5, MoO 3: 0～3, rare earth: 0～3.
Invent the flux of leadless glaze paint among the Chinese patent CN1044595C and formed (mot%): SiO 2: 55～80, Bi 2O 3: 1～8.5, B 2O 3: 3～15, Al 2O 3: 1～9, K 2O:0～9, Na 2O:0～9, Li 2O:0～9, BaO:0～4, SrO:0～4, ZrSiO 4: 1.5～12, SnO 2: 0.3～8.5, La 2O 3: 0～1, MgO:0～3, CaO:0～6, ZnO:0～4, TiO 2: 0～3.
These two patents are not difficult to find out from the formation of flux, give the colour on glazed ceramics temperature low, bright characteristics in order to replace plumbous oxide, all application in various degree Bi 2O 3Low-melting advantage, but it is said the toxicity of bismuth, especially Bi not second to lead 2O 3Introducing cause the glass phase-splitting easily, be difficult for forming uniform vitreum and cause the flux short texture, thereby influence chemical stability, character acidproof, alkaline-resisting etch also can descend, not just also can not cause the colour generation of toner in flux, and the roasting temperature of burning of its pigment is all between 830～950 ℃, and temperature is higher, and energy consumption is big.
Summary of the invention
The object of the present invention is to provide a kind of low temperature ceramic color without lead on glaze, have no side effect, compact structure, chemical stability be good, roasting to burn that temperature is low, the complete perfection of colour system, acid and alkali-resistance etch, matched coefficients of thermal expansion, colour generation is pure, beautiful in colour, glossiness is high, good decorating effect.

Raw materials used technical pure chemical industry raw material or the reagent purifying worker raw material of being of component in the flux of the present invention, unleaded toner use the common unleaded toner of industry to get final product, and market is on sale, can directly buy.
Flux of the present invention, oxide compound that need not be plumbous not only, the influence stability of also need not existing domestic and international correlation technique utilizing and the expensive Bi of color development 2O 3, only with the conventional rich real and inexpensive SiO of reserves 2Al 2O 3And B 2O 3Deng the network constituting body that forms even compact, this lays a good foundation to preparation colour generation beramic color pure, that chemical stability is good.By the composite fluxing agent that a large amount of basic metal and alkaline-earth metal are formed, when reducing the flux melt temperature, improved the acid resistance of pigment greatly by mixed alkali effect.The acidic oxide ZrO of macromolecule low bulk 2, TiO 2, SnO 2Make the structure of flux tightr Deng not only, and cut down the increase of the coefficient of expansion that the adding of basic metal and alkaline-earth metal causes.Each component in the flux not only makes its every physical and chemical index all satisfy international standard, and has avoided the roasting burning temperature height of similar products at home and abroad, the drawback that price is high through the experimental formula of a large amount of scientific and precises.
The preparation method of low temperature ceramic color without lead on glaze of the present invention, simple and easy to do, at first prepare flux, and then preparation pigment, carry out according to following step successively:
(1) preparation of flux: each the flux component raw material that will cross 80～120 mesh sieves mixes, and after the high-temperature fusion, after the cold water shrend, it is standby that oven dry makes unleaded flux;
(2) preparation of pigment: oven dry pulverizing after unleaded flux and the unleaded toner mixing and ball milling is made the work in-process powder;
(3) with half product powder resintering, increase the density and the vividness of pigment, pulverize through secondary ball milling again and make pigment product.
Wherein Kong Zhi optimal processing parameter is respectively:
The melt temperature of flux is 1250～1350 ℃.
The resintering temperature is 700～800 ℃.
The ball mill pulverizing fineness is controlled to be particle diameter＜10 μ m before the resintering, and the ball mill pulverizing fineness is controlled to be particle diameter＜5 μ m behind the resintering.
Low temperature ceramic color without lead on glaze of the present invention, unleaded stripping, have no side effect, compact structure, chemical stability be good, roasting to burn that temperature is low, the complete perfection of colour system, acid and alkali-resistance etch, matched coefficients of thermal expansion, colour generation is pure, beautiful in colour, glossiness is high, good decorating effect.
Low temperature ceramic color without lead on glaze of the present invention, using method is identical with common beramic color, and use temperature is 700～800 ℃, soaking time 8～20 minutes.
Through screen printing, directly print or be sprayed at the ceramic surface, under 700～800 ℃ of temperature, be incubated 8～20 minutes, it is as follows to survey its physicochemical property:
1. glossiness: 80～90%, utilize the digital glossometer of GM-26D type that color technical institute produces in the Japanese strain formula people's commune village, record 45 ° glossiness according to its technical qualification.
2. thermal expansivity: 4.0～7.0 * 10 -6C -1, utilize West Germany to produce 402E type electronic dilatometer.
3. chemical stability: lead release is 0.00mg/dm 2, the pigment variety quantity of cadmium release that part contains the cadmium toner is 0.1～0.26mg/dm 2, soaked 24 hours in 4% acetum down through 22 ± 2 ℃, or 60 ± 2 ℃ of following 0.5%NaCO 3Soak after 40 hours tone, the equal no change of color and luster in the solution.
Compare with existing beramic color, low temperature ceramic color without lead on glaze of the present invention has the following advantages:
1. thoroughly eradicate plumbous murder by poisoning, environment protection health.
2. the roasting temperature of burning is low, and under the well sold and in short supply day by day reality of the energy, energy-saving and cost-reducing just seeming means a great.
3. cost reduces, because of there not being expensive Bi 2O 3Introducing make production cost reduce greatly.
4. colour generation is pure, and glossiness is good, and the roasting temperature range of burning is wide, and chemical stability is good, the acid and alkali-resistance etch.
