Problems solved by technology

[0002] At present, the traditional production method of the ceramic color industry is to use tin ingots to produce rose red materials. The production process is more serious for environmental pollution, and the color tone is also relatively simple. When used at high temperatures above 1250 ° C, pinholes are prone to appear on the glaze surface, and the color is not bright enough. And the fading is more obvious, that is, the use effect is not good under high temperature environment, which limits the application field of this series of pigments to a large extent

Embodiment approach

[0044] As a preferred embodiment, in the step 1, the raw material further includes borax or boric acid.

[0045] The above boric acid or borax plays a role in mineralization, and when combined with other components, it can ensure that the rose red material can be synthesized at the bottom temperature.

[0046] As a preferred embodiment, the raw materials in the step 1 are obtained by reacting the by-products generated in the fused zirconia production process in a stirring tank, and the by-products include soluble silicate solution and calcium oxide solution.

Embodiment 1

[0048] A kind of production method of rose red ceramic colorant, is characterized in that, comprises the following steps:

[0049] Step 1: Mix and grind the raw materials by wet method, the raw materials include: 55kg calcium silicate, 45kg tin oxide, 2%kg potassium dichromate, 3kg borax; in the grinding process, the raw materials: grinding balls: the quality of water The ratio is 1:1.5:0.4, and the grinding time is 1.5h; the raw materials are obtained by reacting the by-products generated in the fused zirconia production process in the stirring tank, and the by-products include soluble silicate solution and calcium oxide solution;

[0050] Step 2: The ground material is subjected to stale treatment at 25°C, and the stale time is 60h;

[0051] Step 3: drying the stale material at a drying temperature of 60°C;

[0052] Step 4: The dried material is sieved with a 30-mesh screen for use;

[0053] Step 5: Heating and calcining the sieved material for 9 hours, keeping at 1245°C f...

Embodiment 2

[0057] A kind of production method of rose red ceramic colorant, is characterized in that, comprises the following steps:

[0058] Step 1: the raw materials are mixed and ground by wet method, and the raw materials include: 50 kg of calcium silicate, 40 kg of tin oxide, 1 kg of potassium dichromate, and 1 kg of boric acid; in the grinding process, the mass ratio of raw materials: grinding balls: water It is 1:1.5:0.3, and the grinding time is 1h; the raw materials are obtained by reacting the by-products generated in the fused zirconia production process in the stirring tank, and the by-products include soluble silicate solution and calcium oxide solution;

[0059] Step 2: The ground material is subjected to stale treatment at 20°C, and the stale time is 50h;

[0060] Step 3: drying the stale material at a drying temperature of 50°C;

[0061] Step 4: The dried material is sieved with a 20-30 mesh screen for use;

[0062] Step 5: Heating and calcining the sieved material for 8h...

Abstract

The invention relates to the technical field of production methods of ceramic pigments, in particular to a production method of a rose-bengal ceramic pigment which comprises the following components in parts by mass: 50-60 parts of calcium silicate, 40-50 parts of tin oxide and 1-3 parts of potassium dichromate. According to the present invention, the raw material is the by-product generated during the electric melting zirconia production process, such that the waste material is recycled, the advantages of low cost and easy obtaining are provided, the rose-bengal ceramic pigment is synthesized at the low temperature through the grinding, the aging, the drying screening, the calcining, the grinding, the cleaning and the drying process, and compared with the existing rose-bengal ceramic pigment, the high temperature resistance can be improved; high-temperature glaze defects are reduced, the color is full, and the color development effect and color matching requirements of ceramic products are met.
