Problems solved by technology

However, the color material needs to be pre-synthesized by calcination, pickling, elutriation and other processes. The addition of mineralizers makes the process relatively complicated and polluting, and the relative cost is also high, which does not meet the needs of the current international community for energy conservation and emission reduction. Urgent need for technical improvement

Embodiment 1

[0019] 1) Preparation of ultra-fine slag: After coarsely grind the iron slag with a vibrating mill to pass through an 80-mesh sieve, grind it evenly in a mortar, put it in a high-energy ball mill, and ball mill it at a speed of 1400r / min for 70 minutes After taking it out, it is passed through a 200-mesh sieve to obtain superfine slag.

[0020] 2) Preparation of clinker containing slag: In terms of mass percentage, combine 13% feldspar, 27% borax, 8% potassium carbonate, 3% sodium carbonate, 5% limestone, 8% barium carbonate, 33% zirconium silicate and 3% boric acid are mixed uniformly to obtain a mixture. Add superfine slag accounting for 8% of the mass of the mixture to the mixture and mix it evenly by ball milling. Pass a 200 mesh sieve to remove the sieve and put the sieve into the oxidation In an aluminum crucible, the temperature is kept at 1250°C for 40 minutes for melting, and a low-temperature frit is obtained after water quenching.

Embodiment 2

[0029] 1) Preparation of ultra-fine slag: After coarsely grind the iron slag with a vibrating mill to pass an 80-mesh sieve, grind it evenly in a mortar, put it in a high-energy ball mill, and ball mill it at a speed of 1500r / min for 60 minutes. After taking it out, it is passed through a 200-mesh sieve to obtain superfine slag.

[0030] 2) Preparation of clinker containing slag: In terms of mass percentage, 14% feldspar, 24% borax, 9% potassium carbonate, 2% sodium carbonate, 4% limestone, 9% barium carbonate, 34% zirconium silicate and 4% boric acid are mixed uniformly to obtain a mixture. Add superfine slag, which accounts for 10% of the mass of the mixture, and mix it evenly by ball milling. Pass a 200-mesh sieve to remove the sieve and put the sieve into the oxidation In an aluminum crucible, the temperature is kept at 1300°C for 30 minutes for melting, and a low-temperature frit is obtained after water quenching.

Abstract

The invention provides a method for preparing low temperature green antique glaze by utilizing iron-ore slag. The method comprises the steps of mixing 30-45% of low temperature frit, 25-40% of feldspar, 18-25% of quartz, 3-5% of calcite, 2-4% of talcum and 2-5% of calcium phosphate by mass percent to obtain mixed powder, then adding sodium tripolyphosphate and carboxymethyl cellulose and mixing the materials uniformly, fine-grinding the mixture until the grain size is 200-250 meshes, then adding water to obtain glaze slurry, and adjusting the specific gravity of the glaze slurry to be 1.6-1.7g / cm<3>; applying the glaze slurry to a green body uniformly, and insulating the green body at 1080-1120 DEG C, thus obtaining the low temperature green antique glaze. The method has the beneficial effects that the prepared glaze has high glossiness, pure color and stable properties; mineralizers are not used, thus greatly reducing the costs of the raw materials, achieving waste reuse, reducing pollution, saving ore resources and protecting the ecological environment.

Description

Technical field [0001] The invention belongs to the field of materials science, and specifically relates to a method for preparing low-temperature green antique glaze by using iron slag. Background technique [0002] With the improvement of people's living standards, the market puts forward higher requirements for ceramic color and glaze. Green glaze is deeply loved by people for its bright colors and rich dynamic feeling. At present, most of the colorants used in the green glaze on the market are chromium oxide. 3+ It is a hair color element. However, the chromium oxide green glaze has the disadvantages of dark tone and not bright enough, which affects its decoration and its application is also limited. In order to improve the vividness and coloring ability of chrome oxide green glaze, many scholars have adopted the production method of adding mineralizer. For example, Wu Wenfang et al. have treated various halides such as NaF, NaCl, NaBr, NH 4 Cl, etc. carried out a detailed...
