The above-mentioned parts are all parts by weight.

[0031] The preparation method of antibacterial ceramic glaze comprises the steps:

[0032] Firstly, the raw materials zinc oxide and titanium dioxide are pre-calcine...

Embodiment 2

[0040] 41 parts of feldspar powder with fineness below 325 mesh, 22 parts of quartz powder with fineness below 250 mesh, 15 parts of calcite powder with fineness below 250 mesh, 1 part of refined Suzhou soil, 13 parts of zinc oxide, fineness of 2 parts of dolomite below 250 mesh, 7 parts of barium carbonate, 8.5 parts of titanium dioxide, and 3.5 parts of copper oxide.

[0041] The pre-calcination of the raw materials zinc oxide and titanium dioxide is the same as in Example 1.

[0042] The preparation method of antibacterial ceramic glaze comprises the steps:

[0043] (1) Preparation of glaze slurry

[0044] Mix glaze raw materials, balls, and water in a weight ratio of 1:1.5:1, wet ball mill through a ball mill, and pass through a 250-mesh sieve. When the sieve residue is 0.08%, the specific gravity of the glaze slurry is 1.42.

[0045] (2) Glazing

[0046] The above-mentioned glaze slurry is applied to a ceramic bisque body with a water absorption rate of 14.6% to form a...

Embodiment 3

[0050] 44 parts of feldspar powder with fineness below 325 mesh, 25 parts of quartz powder with fineness below 250 mesh, 11 parts of calcite powder with fineness below 250 mesh, 2 parts of refined Suzhou soil, 14.5 parts of zinc oxide, fineness of 4 parts of dolomite below 250 mesh, 6 parts of barium carbonate, 9 parts of titanium dioxide, and 2 parts of copper oxide.

[0051] The pre-calcination of the raw materials zinc oxide and titanium dioxide is the same as in Example 1.

[0052] The preparation method of antibacterial ceramic glaze comprises the steps:

[0053] (1) Preparation of glaze slurry

[0054] Mix glaze raw materials, balls, and water in a weight ratio of 1:1.5:1, wet ball mill through a ball mill, and pass through a 250-mesh sieve. When the sieve residue is 0.12%, the specific gravity of the glaze slurry is 1.50.

[0055] (2) Glazing

[0056] The above-mentioned glaze slurry is applied on a ceramic bisque body with a water absorption rate of 12.3%, forming a g...

Abstract

The invention discloses a low-cost antibacterial ceramic glaze, which is prepared from the following ingredients in parts by weight: 51.0 to 54.5 parts of SiO2, 8.1 to 9.4 parts of Al2O3, 0.8 to 1.5 parts of Na2O, 5.8 to 8.5 parts of CaO, 3.8 to 4.5 parts of K2O, 7 to 9 parts of TiO2, 12.5 to 14.5 parts of ZnO, 3.1 to 5.4 parts of BaO, 0.5 to 1.2 parts of MgO, 2.0 to 3.5 parts of CuO and less than 0.7 part of other ingredients. The invention also provides a preparation method of the antibacterial ceramic glaze. The preparation method comprises the following steps: (1) preparing glaze slip; (2) glazing; and (3) firing the green body. Under the condition of the components, the raw materials and the preparation method, the antibacterial ceramic glaze can be prepared, the antibacterial property requirement is met, the dissolution amount of lead and cadmium in the antibacterial ceramic glaze is not detected, and the antibacterial ceramic glaze can be used as a tea set and daily tableware decoration and is very safe, so that the body health of people is ensured.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a low-cost antibacterial ceramic glaze and a preparation method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the quality of life, and the awareness of preventing diseases from entering the mouth has increased. Ceramic products, which are widely used in daily necessities, have antibacterial effects and are more and more popular. [0003] Antibacterial ceramics is a new type of environmentally friendly functional material. Currently, there are two most widely used antibacterial technologies. The first is the surface antibacterial layer technology. A layer of antibacterial materials is applied on the surface of the ceramic glaze layer, such as photocatalytic titanium oxide materials. , using the oxidation-reduction reaction of trivalent titanium io...
