201310022848.X discloses a self-cleaning glaze for sanitary ware, which enhances the stain resistance by applying a self-cleaning glaze on the outer layer of the opaque glaze. This method increases the production process and production cost, and has no inhibitory effect on the formation of scale. The formation of scale layer will make the stain resistance worse and worse
201310450589.0 announced a method for preparing antibacterial sanitary ceramics. By adding nano-silver antibacterial agents to the glaze, the sanitary ceramics have antibacterial properties, but this method cannot inhibit the formation of dirt on the surface. The scale layer of silver ions is difficult to penetrate, and the antibacterial effect cannot be guaranteed

Embodiment 1

[0039] Sanitary ceramics with anti-scaling function include the following components (% by weight): 9 calcite, 6 dolomite, 2 talc, 31 feldspar, 26 quartz, 2 kaolin, 11 zircon, 1 barium carbonate, 1 burnt zinc oxide, 7wt% copper-loaded medical stone (copper loading) 2, 3wt% cerium oxide doped tourmaline 8, sepiolite mineral nanofiber 1.

[0040] The production process of the antiscaling functional sanitary ceramics of the present invention comprises the following steps:

[0041]Glaze preparation: mix calcite, dolomite, talc, feldspar, quartz, kaolin, zircon, barium carbonate, and burnt zinc oxide according to the ratio, and add carboxymethyl cellulose (CMC) with a mass ratio of 0.3% of the above glaze , add water so that water accounts for 35% of the total mass, use zirconia balls as the grinding body, add balls for wet grinding according to the ratio of material: ball = 1:1.5, the glaze particle size D50 is 5 μm, pass through a 120 mesh sieve, and remove iron to obtain For th...

Embodiment 2

[0048] Sanitary ceramics with anti-scale function include the following components (% by weight): 8 calcite, 6 dolomite, 2 talc, 30 feldspar, 25 quartz, 2.5 kaolin, 12 zircon, 0.5 barium carbonate, 1 burnt zinc oxide, 7wt% copper-loaded medical stone 3, 2wt% lanthanum oxide doped medical stone 8, sepiolite mineral nanofiber 2.

[0049] The production process of the antiscaling functional sanitary ceramics of the present invention comprises the following steps:

[0050] Glaze preparation: mix calcite, dolomite, talc, feldspar, quartz, kaolin, zircon, barium carbonate, and burnt zinc oxide according to the ratio, add CMC with a mass ratio of 0.3% of the above glaze, and add water to make the water account for the water. 40% of the total mass of the material, use zirconia balls as the grinding body, add grinding balls according to the ratio of material: ball = 1:1.5, and carry out wet grinding. When the glaze particle size D50 is 5 μm, pass through a 120 mesh sieve to remove iron...

Embodiment 3

[0055] Other steps are the same as in Example 1, except that calcite, dolomite, talc, feldspar, quartz, kaolin, zircon, barium carbonate, burnt zinc oxide, copper-loaded medical stone, 3wt% cerium oxide doped tourmaline The components are respectively changed to calcite 9, dolomite 5, talc 3, feldspar 31, quartz 24, kaolin 2, zircon 12, barium carbonate 1, burnt zinc oxide 1, 7wt% copper-loaded medical stone 4, 2wt% Neodymium oxide doped with 70wt% tourmaline 28wt% medical stone6, sepiolite mineral nanofiber2. The highest firing temperature is 1200°C. Its properties are: the growth rate of glazed calcite crystals is reduced by 65%, the algae inhibition rate is 97%, the antibacterial rate is 98%, and the Vickers hardness is 660Hv.

Abstract

The invention relates to scale-inhibition function sanitary ceramics and a preparation method thereof. The ceramics comprise a ceramic glaze material, an inorganic antibacterial algae-removing material, a far-infrared radiation material and meerschaum mineral nano fiber, the percentage content of each component in the total mass of the ceramic raw material are 77-93% of the ceramic glaze material, 1-5% of the inorganic antibacterial algae-removing material, 5-15% of the far-infrared radiation material and 1-3% of the meerschaum mineral nano fiber. The inorganic antibacterial algae-removing material is a copper-loaded inorganic antiseptic; the far-infrared radiation material is a compound of a natural mineral material and a rare earth material, and the meerschaum mineral nano fiber is the product by crushing meerschaum through air-flow. Under condition that the preparation method of the sanitary ceramics is not changed, the inorganic antibacterial algae-removing material, the far-infrared radiation material and the meerschaum mineral nano fiber are added in the sanitary ceramics glaze material, and glaze antibiosis and scale inhibition functionalization can be realized.

Description

technical field [0001] The invention relates to sanitary ceramics with scale-resisting function, in particular to a sanitary ceramic glaze capable of inhibiting the formation of scale on the glaze surface and having an antibacterial function. Background technique [0002] With the continuous deepening of China's urban transformation and real estate development, the sanitary ceramics industry has ushered in a new golden period of development. More and more ceramic manufacturers have joined the ranks. The scale of the industry has expanded rapidly, and unprecedented "prosperity" has appeared. ". In 2013, the cumulative total output of sanitary ceramic products in the country reached 195 million pieces; in 2014, the cumulative production of sanitary ceramic products by enterprises above designated size in the country exceeded 196 million pieces. However, the growth of the sanitary ceramics industry is mainly due to the growth of the low-end product demand market. Compared with...
