[0022] (2) Remove iron from the above glaze slurry in a 18000 Gauss iron remover;

[0023] (3) Sieve the glaze slurry after iron removal, the fineness of the sieve is 250 mesh, and the sieve residue is less than 0.02%;

[0024] (4) Stale the sieved glaze slurry for 24 hours and set aside.

Embodiment 2

[0026] The raw material formula of present embodiment daily ceramic glaze is as follows: potassium feldspar 38%, kaolin 12%, barium carbonate 4.6%, lanthanum carbonate 1.2%, lithium carbonate 1.8%, zinc oxide 6%, cerium oxide 0.7%, trioxide Diyttrium 0.7%, strontium carbonate 1.5%, quartz 33.5%.

[0027] (1) Mix and pulverize the raw materials of the daily-use ceramic glaze according to the proportion of the component formula, and carry out wet ball milling. The wet ball milling is carried out according to material: stone: water = 1:1.8:1, and glaze slurry is obtained;

[0028] (2) Remove iron from the above glaze slurry in a 18000 Gauss iron remover;

[0029] (3) Sieve the glaze slurry after iron removal, the fineness of the sieve is 250 mesh, and the sieve residue is less than 0.02%;

[0030] (4) Stale the sieved glaze slurry for 25 hours and set aside.

Embodiment 3

[0032] The raw material formula of present embodiment daily ceramic glaze is as follows: potassium feldspar 37%, kaolin 11.6%, barium carbonate 5.3%, lanthanum carbonate 1.4%, lithium carbonate 1.6%, zinc oxide 5.4%, cerium oxide 0.8%, trioxide Diyttrium 0.8%, strontium carbonate 1.5%, quartz 34.6%.

[0033] (1) Mix and pulverize the raw materials of the daily-use ceramic glaze according to the proportion of the component formula, and carry out wet ball milling. The wet ball milling is carried out according to material: stone: water = 1:1.8:1, and glaze slurry is obtained;

[0034] (2) Remove iron from the above glaze slurry in a 18000 Gauss iron remover;

[0035] (3) Sieve the glaze slurry after iron removal, the fineness of the sieve is 250 mesh, and the sieve residue is less than 0.02%;

[0036] (4) Stale the sieved glaze slurry for 26 hours and set aside.

Abstract

The invention discloses a daily ceramic glaze and a preparation method of the daily ceramic glaze. The daily ceramic glaze is composed of the following components in percentage by weight: 36-38% of potassium feldspar, 10-12% of kaolin, 4.5-5.5% of barium carbonate, 1.2-1.4% of lanthanum carbonate, 1.6-1.8% of lithium carbonate, 4-6% of zinc oxide, 0.6-0.8% of cerium dioxide, 0.6-0.8% of yttrium oxide, 1.5-2% of strontium carbonate, and 33-35% of quartz. The preparation method of the daily ceramic glaze comprises the steps of: mixing and crushing the raw materials of the daily ceramic glaze according to the formula ratio, and carrying out wet ball milling to obtain glaze slurry; and removing iron, screening and aging. The daily ceramic glaze contains multiple rare earth metal oxides, which generate synergism with each other, thus the luster of the daily ceramic glaze is improved, the glaze surface is smooth, and the daily ceramic glaze has good hardness, rupture strength and fracture toughness.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, and in particular relates to a daily-use ceramic glaze and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the quality and grade requirements of daily-use ceramic products are also getting higher and higher, and the brightness of the ceramic glaze layer is a main reason that directly affects the product grade. Since the current glaze raw material formula and production process are relatively old, the surface of fired ceramic products for daily use is not smooth and bright enough. In order to improve the surface brightness of daily ceramic products, meet consumer demand, and occupy the high-end market, researchers have studied After a lot of research, the patent CN200910192404.4 discloses a high-refractive index ceramic glaze for daily use, which improves the gloss of the glaze surface through the combination of various gloss-en...
