Problems solved by technology

[0002] The current ceramic body, whether it is white porcelain or stoneware, blindly requires the lower the iron content, the better, but this kind of high-quality china clay, kaolin is limited, and the mining is disorderly, so that a high-quality Once the china clay kaolin mine was discovered, it was mined in just a few years or more than ten years, and the topsoil and tailings with a slightly higher iron content were ignored, resulting in a waste of resources
Or the removal of iron by a high-power iron remover will cause environmental pollution and waste of energy.

Embodiment 1

[0039] This embodiment provides a medium-temperature black body porcelain, which is prepared from a blank and a glaze; wherein,

[0040] The raw materials for making the blanks include: 20-23% by weight of porcelain washing mud, 9-12% by weight of plaster, 28-35% by weight of white mud, and 20-28% by weight of white clay. Red purple sand shale, 21-25% by weight quartz and 5-8% by weight moraine;

[0041] The raw materials for making the glaze include: potassium feldspar with a weight percentage of 30-35%, albite with a weight percentage of 25-30%, quartz with a weight percentage of 25-30%, and a weight percentage of 10-15% Limestone, 0-4% by weight zinc oxide, 5-12% by weight barium carbonate, 3-8% by weight talc, 5-8% by weight kaolin and 5-8% by weight 12% of colorant or 3 to 6% by weight of chromophoric oxide;

[0042] Alternatively, the raw materials for making the glaze include: potassium feldspar with a weight percentage of 16-20%, albite with a weight percentage of 13-1...

Embodiment 2

[0051] On the basis of Example 1, this example further provides a method for preparing medium-temperature black body porcelain, which includes the following production steps:

[0052] Step 1: Take porcelain washing clay with a weight percentage of 20-23%, plaster with a weight percentage of 9-12%, white mud with a weight percentage of 28-35%, and red purple sand shale with a weight percentage of 20-28% , 21-25% by weight of quartz and 5-8% by weight of moraine rock;

[0053] Step 2, ball milling the ingredients in step 1, wherein the ratio of ingredients, balls, and water is 1:2:1.2, ball milling until the sieve residue of the 250 mesh sieve of the ingredients granularity is 0.06%, and then Press filtration to form a mud cake with a water content of 21 to 27%. In this embodiment, as a preferred embodiment, sodium polyacrylate with a concentration of 0.06% is added during the ball milling process, and the ball milling time is 30 to 36 hours;

[0054] Step 3. On the basis of st...

Embodiment 3

[0071] A method for preparing medium-temperature black-bodied porcelain, which comprises the following production steps:

[0072] Step 1: Take porcelain washing clay with a weight percentage of 20-23%, plaster with a weight percentage of 9-12%, white mud with a weight percentage of 28-35%, and red purple sand shale with a weight percentage of 20-28% , 21-25% by weight of quartz and 5-8% by weight of moraine rock;

[0073] Step 2, ball milling the ingredients in step 1, wherein the ratio of ingredients, balls, and water is 1:2:1.2, ball milling until the sieve residue of the 250 mesh sieve of the ingredients granularity is 0.06%, and then Press filtration to form a mud cake with a water content of 21-27%;

[0074] Step 3. On the basis of step 2, the billet is formed by hand drawing and rolling or grouting, and the formed billet is naturally dried;

[0075] Step 4. After the formed blank is dried until the water content is lower than 4%, the glaze is applied, wherein the speci...

Abstract

The invention discloses medium-temperature black-body ceramic. The medium-temperature black-body ceramic is prepared by a preform body and glaze, wherein the preform body comprise, by weight percentage, 20-23% of washed porcelain clay, 9-12% of grey clay, 28-35% of white clay, 20-28% of red purple-sand shale, 21-25% of quartz and 5-8% of tillite; the glaze comprises, by weight percentage, 30-35% of potassium feldspar, 25-30% of albite, 25-30% of quartz, 10-15% of limestone, 0-4% of zinc oxide, 5-12% of barium carbonate, 3-8% of talcum, 5-8% of kaolin and 5-12% of pigment or 3-6% of coloring oxide. The medium-temperature black-body ceramic is high in sintering yield, stable in performance and free of glaze cracking.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to a medium-temperature black tire ceramic and a preparation method thereof. Background technique [0002] The current ceramic body, whether it is white porcelain or stoneware, blindly requires that the lower the iron content, the better, but this high-quality porcelain clay, kaolin is limited, and the mining is disordered, so that a high-quality porcelain clay Once discovered, the kaolin mine of porcelain clay was mined in just a few years or more than ten years, and the topsoil and tailings with a slightly higher iron content were ignored, resulting in a waste of resources. Or the removal of iron by panning high-power iron remover causes environmental pollution and energy waste. [0003] Therefore, a high-quality medium-temperature black tire porcelain and a preparation method thereof are provided. SUMMARY OF THE INVENTION [0004] To this end, the present inventio...
