Problems solved by technology

[0004] However, during the actual production of the glaze in the above-mentioned technical solution, the inventors observed that the cadmium carbonate used as a flux in the glaze is highly toxic and irritating, requiring storage environment and processing environment. They are all very high, which increases the glaze processing cost to a certain extent, and it is inevitable that some cadmium compounds and cadmium dust will leak during processing, which brings potential harm to the health of operators.

Embodiment 1

[0026] A bright red glaze for ceramics, which is composed of the following components by weight: 30 parts of potassium feldspar, 18 parts of quartz, 6 parts of marble, 8 parts of kaolin, 6 parts of transparent frit, 50 parts of water, and 2 parts of bright red material , 1 part of red coral stone powder.

[0027] Its preparation method is as follows:

[0028] Step 1, after the red coral stone is crushed, ball milling is carried out, and the powder obtained after ball milling is passed through a 325-mesh standard sieve to obtain red coral stone powder for use;

[0029] Step 2: Mix 30 parts of potassium feldspar, 18 parts of quartz, 6 parts of marble, 8 parts of kaolin, 6 parts of transparent frit, and 50 parts of water, and ball mill it into glaze slurry. The ball milling time is 16 hours, and the magnetic field strength of the glaze slurry is The 10,000 Gauss iron remover removes iron three times, and the glaze slurry passes through a 325-mesh standard sieve;

[0030] Step 3...

Embodiment 2

[0033] A bright red glaze for ceramics, which consists of the following components by weight: 50 parts of potassium feldspar, 38 parts of quartz, 13 parts of marble, 15 parts of kaolin, 10 parts of transparent frit, 70 parts of water, and 8 parts of bright red material , 3 parts of red coral stone powder.

[0034] Its preparation method is as follows:

[0035] Step 1, after crushing the red coral stone, ball milling is carried out, and the powder obtained after ball milling is passed through a 380-mesh standard sieve to obtain red coral stone powder for use;

[0036] Step 2: Mix 50 parts of potassium feldspar, 38 parts of quartz, 13 parts of marble, 15 parts of kaolin, 10 parts of transparent frit, and 70 parts of water, and ball mill it into glaze slurry. The 10,000 gauss iron remover removes iron 5 times, and the glaze slurry passes through a 380-mesh standard sieve;

[0037] Step 3, mix 8 parts of bright red material and 3 parts of red coral stone powder evenly and ball-m...

Embodiment 3

[0040] A bright red glaze for ceramics, which consists of the following components by weight: 45 parts of potassium feldspar, 30 parts of quartz, 10 parts of marble, 13 parts of kaolin, 9 parts of transparent frit, 65 parts of water, and 6 parts of bright red material , 2.5 parts of red coral stone powder.

[0041] Its preparation method is as follows:

[0042] Step 1, after crushing the red coral stone, ball milling is carried out, and the powder obtained after ball milling is passed through a 380-mesh standard sieve to obtain red coral stone powder for use;

[0043] Step 2: Mix 45 parts of potassium feldspar, 30 parts of quartz, 10 parts of marble, 13 parts of kaolin, 9 parts of transparent frit, and 65 parts of water, and ball mill it into glaze slurry. The 10,000 gauss iron remover removes iron 4 times, and the glaze slurry passes through a 380-mesh standard sieve;

[0044] Step 3, mix 6 parts of bright red material and 2.5 parts of red coral stone powder evenly and ball...

Abstract

The invention discloses a bright red glaze for ceramics, and a preparation method thereof, and relates to the technical field of ceramic glazes, wherein the bright red glaze is prepared from the following components by weight: 30-50 parts of potassium feldspar, 18-38 parts of quartz, 6-13 parts of marble, 8-15 parts of kaolin, 6-10 parts of transparent frit, 50-70 parts of water, 2-8 parts of bright red pigment and 1-3 parts of red corallite powder. According to the invention, cadmium carbonate is replaced with the red corallite powder as the fluxing agent, wherein the main component of the red corallite powder is CaCO3, so that the requirement on the storage environment of the red corallite powder is low, and the storage cost of the raw materials is saved; the red corallite powder has redattribute, so that the use of the bright red pigment is reduced so as to further reduce the cost; by using the red corallite powder to replace cadmium carbonate, the toxic substances such as cadmiumcompounds, cadmium dust and the like cannot be generated in the processing process so as to further improve the processing environment quality and ensure the body health of operators.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a scarlet glaze for ceramics and a preparation method thereof. Background technique [0002] The red in Chinese red porcelain means peace, auspiciousness, celebration, prosperity, longevity, nobility, harmony, reunion, success, etc. It has rich cultural connotations and lofty spiritual realm. With the continuous advancement of technology, Chinese red is gradually Applied to daily life utensils, the red porcelain that could only be enjoyed by the royal family in ancient times gradually entered our modern life. [0003] In the Chinese patent whose authorization notification number is CN102491794B, a kind of scarlet glaze for ceramics is disclosed, which consists of 30-50 parts of potassium feldspar, 20-40 parts of quartz, 5-15 parts of marble, 8-15 parts of kaolin, and transparent frit 6 to 10 parts, 0.1 to 0.5 parts of cadmium carbonate, 4 to 12 parts of scarlet material a...
