[0022] The preparation method of enamel black glaze comprises the following steps:

[0023] a. First grind and mix 9-11 parts of vanadium-titanium-magnetite titanium tailings or flotation titanium tailings with 0.1-0.3 parts of sodium peroxide, and then add 25-28 parts of feldspar, 10-13 parts of quartz, 24-28 parts of borax, 7-9 parts of sodium nitrate, 5-7 parts of sodium carbonate, 5-7 parts of calcium fluoride, 0.1-0.3 parts of sodium fluorosilicate, 2-4 parts of sodium fluoroaluminate, cobalt trioxide 1-2 parts, 0.3-0.5 parts of nickel nitrate, 1-2 parts of calcium oxide, 0.6-1.0 parts of manganese dioxide are mixed evenly, and the mixing uniformity is ≥98%;

[0024] b. Transfer the mixed raw materials into an electric furnace or kiln and heat to 820-870°C for 1 hour, then heat to 1200-1250°C and hold for 2 hours to obtain a uniform molten enamel;

[0025] c. Pour the molten enamel into cold water and quench it, dry it at 120-150° C. for 20 minutes to obtain a dried enam...

Embodiment 1

[0031] Take 11 parts of vanadium-titanium-magnetite titanium-selected tailings by weight and grind and mix them evenly with 0.2 part of sodium peroxide, then add 28 parts of feldspar, 13 parts of quartz, 28 parts of borax, 7.5 parts of sodium nitrate, and 5.3 parts of sodium carbonate , 7 parts of calcium fluoride, 0.3 parts of sodium fluorosilicate, 3 parts of sodium fluoroaluminate, 0.65 parts of dicobalt trioxide, 0.3 parts of nickel nitrate, 2 parts of calcium oxide, 0.7 parts of manganese dioxide, mixing, uniformity ≥ 98% , all the materials are transferred to an electric furnace or kiln and heated to 850°C for 1 hour, then heated to 1200°C and held for 2 hours to obtain a uniform molten enamel, poured into cold water, quenched, and dried at 130°C. 100 parts of enamel, 2.5 parts of quartz, 1 part of sodium fluoroborate and 3 parts of clay are crushed to a particle size of -200 mesh ≥ 98% to prepare black enamel glaze.

[0032] The above-mentioned enamel black glaze is coa...

Embodiment 2

[0034] Take 9 parts of vanadium-titanium-magnetite titanium tailings and 0.2 parts of sodium peroxide to grind and mix evenly according to the weight ratio, then add 25 parts of feldspar, 11.5 parts of quartz, 26 parts of borax, 7.5 parts of sodium nitrate, and 5.3 parts of sodium carbonate , 7 parts of calcium fluoride, 0.3 parts of sodium fluorosilicate, 3 parts of sodium fluoroaluminate, 1.5 parts of cobalt nitrate, 0.3 parts of nickel nitrate, 1.5 parts of calcium oxide, 0.7 parts of manganese dioxide, mixing, uniformity ≥ 98%, all The material is transferred to an electric furnace or a kiln and heated to 850°C for 1 hour, then heated to 1200°C and held for 2 hours to obtain a uniform molten enamel material, poured into cold water, quenched, and dried at 130°C. 100 parts of enamel, 2.5 parts of quartz, 1 part of sodium fluoroborate and 3 parts of clay are crushed to a particle size of -200 mesh ≥ 98% to prepare black enamel glaze.

Abstract

The invention belongs to the technical field of enamel materials, and particularly relates to an enamel black glaze and a preparation method thereof. The enamel black glaze is prepared from the following raw materials in parts by mass: 9-11 parts of vanadium titanomagnetite titanium separation tailing or floatation titanium tailing, 0.1-0.3 part of sodium peroxide, 25-28 parts of feldspar, 10-13 parts of quartz, 24-28 parts of borax, 7-9 parts of sodium nitrate, 5-7 parts of sodium carbonate, 5-7 parts of calcium fluoride, 0.1-0.3 part of sodium fluosilicate, 2-4 parts of sodium fluoroaluminate, 1-2 parts of cobalt compound, 0.3-0.5 part of nickel nitrate, 1-2 parts of calcium oxide and 0.6-1.0 part of manganese peroxide. The enamel black glaze provided by the invention has the advantages of favorable glaze surface glossiness, high blackness, high black pigmentation, excellent ceramic formation performance, excellent physiochemical properties and excellent light-heat convertibility, and is easy to clean.

Description

technical field [0001] The invention belongs to the technical field of enamel materials, and in particular relates to black enamel glaze and a preparation method thereof. Background technique [0002] Enamel black glaze has high chemical stability, no corrosion, no aging, and no secondary pollution during use. This is because enamel black glaze will absorb a large amount of soluble sodium, silicon, iron, Cobalt, vanadium, titanium and other oxides are transformed into insoluble silicate minerals into the crystal lattice and glass phase, and become porcelain minerals with stable structure. As the temperature rises, crystal phase and glass phase are gradually formed, vanadium and titanium elements are enriched in the crystal grains, and the crystal grains are bonded, isolated, and surrounded by the quartz glass body to form a compound with a stable structure. Black glaze has high photothermal absorption rate, infrared radiation rate and high photothermal conversion efficiency...
