The invention discloses a preparation method of matte
glaze sanitary
ceramic. The preparation method comprises the steps of carrying out ball milling on 27.8%-29% of
quartz, 25.5%-26.9% of Changding
potassium feldspar, 13.55%-15.5% of
calcite, 3.83%-4.3% of
dolomite, 3%-3.3% of Zhangzhou kaolin, 9%-10.1% of
zirconium silicate, 9.83%-10.1% of aluminum
oxide, 3.2%-3.4% of
zinc oxide, 0.03%-0.04% of
sodium carboxymethylcellulose and 1.06%-1.95% of
sodium carbonate until the particle size of
slurry is smaller than 10 microns and the ratio is 60%-65%, adding
ceramic pigments, continuing to carry out ball milling until the particle size of
slurry is smaller than 10 microns and the ratio is 69%-71%, sieving by virtue of a 180-mesh
sieve so as to obtain uniform sanitary
ceramic matte
glaze slurry, spraying the sanitary ceramic matte
glaze slurry to the surface of a sanitary ceramic blank, adequately
drying, firing in a
tunnel kiln at 1200-1250 DEG C for 15-18 hours, and cooling, so as to obtain the matte glaze sanitary ceramic product. The prepared matte glaze sanitary ceramic has a special matte effect and pure colors and is rich in aesthetic
perception, and the problem of poor
sewage resistance of traditional matte glaze is further overcome.
