Abstract
The invention relates to a high-temperature preparation method of chrome-tin purple pigment, which includes steps of mixing ingredient materials comprising, by weight percentage, 85-90% of superfine tin oxide, 1-5% of lithium fluoride, 1.5-3% of ammonium fluoride, 0.5-1.5% of erbium oxide, 3-8% of potassium nitrate, 2-10% of chromium compound and 0.4-1% of ammonium compound, calcining the materials at high temperature, and then grinding by a ball mill, drying and crushing. The pigment prepared by the different formulas can resist the temperature of 1350 DEG C, the color of the pigment is bright, the water content thereof is lower than 0.3%, the fineness thereof (residue screened by a 320-mesh screen) is lower than 0.1%, and the pigment is used for the field of high-temperature color glaze, is low in preparation cost and wide in market prospect.
Description
Technical field
The present invention relates to the pigment technology field, relate in particular to a kind of preparation method of high temperature chromium-tin purple dye.
Background technology
Chromium-tin purple dye is the new ceramics pigment of bringing into use after nineteen fifties in ceramic industry.Since the eighties, the high temperature rapid firing technology for production of ceramics develops rapidly in American-European countries, due to its have energy-conservation, reduce plumbous, cadmium heavy metal to the harm of human body and be convenient to the superiority such as industrialization, this technique has become the inexorable trend of Production of Ceramics development.So far, Germany Di Gaosha company, the companies such as BASF AG and Britain village letter Wan Feng develop in succession can be in the high quality chromium tin violet pigment of 1300 ℃ of painted uses of ceramic glaze, and it has advantages of that high-temperature stable, quality are bright-coloured, lucid and lively, but the price of imported product is high.
In prior art, the chromium tin violet pigment of domestic production can only be used at a lower temperature ceramic colour glaze and decorate, how to solve the present situation of this product of dependence on import, can reduce production costs and can satisfy and fill up the domestic technique blank, minimizing is to external dependence, more the stretchy domestic demand, be the problem that the present invention is devoted to solve.
Summary of the invention
The objective of the invention is, the problem that exists for prior art provides a kind of preparation method of high temperature chromium-tin purple dye, has solved that prior art is existing can only be used at a lower temperature ceramic colour glaze and decorate, and the problem of high cost.
Technical scheme of the present invention is as follows: a kind of preparation method of high temperature chromium-tin purple dye is characterized in that: described method comprises the steps:
A, by following component (weight percent) preparation chromium-tin purple dye:
Superfine tin oxide: 85～90%, lithium fluoride: 1～5%
Neutral ammonium fluoride: 1.5～3 % Erbium trioxides: 0.5～1.5 %
Saltpetre: 3～8 % chromium compoundses: 2～6 %
Ammonium compound: 0.4～1 %
After B, the top batching of mixing, high-temperature calcination in muffle furnace, temperature is: 1300～1380 ℃, calcination time is 10～16 hours, soaking time 5～8 hours;
C, the pigment after calcining carry out ball milling through Quick ball grinder, filter washing, 110 ℃ of oven dry and pulverizing.
Wherein, described chromium compounds is: wherein one or more of potassium bichromate, lead chromate, chromic oxide are compound.
Wherein, described ammonium compound is: wherein one or more of primary ammonium phosphate, ammonium chloride, Neutral ammonium fluoride are compound.
Beneficial effect of the present invention is: after the present invention adopts technique scheme, by this pigment that uses different formulas to prepare, after preparing burden above mixing, in high-temperature calcination, ball milling, oven dry and pulverizing, its heatproof of the pigment of producing can reach 1350 degree, for the high temperature color glaze field, and gorgeous degree (C) is 16-20, moisture (%):＜0.3, and fineness (320 mesh screen residue %):＜0.1, its preparation cost is low, has market outlook widely.Solved the prior art products dependence on import, the high in cost of production problem.
