Example Embodiment

[0045] The present invention also provides a method for preparing the FFC sanitary ceramics of the FFC glaze with high antifouling ability, which includes the following steps:

[0046] Pre-ball milling of the frit: Weigh the frit according to the ratio, and pre-mill the frit of the formula;

[0047] Ball milling: Weigh the other raw materials except for the frit according to the ratio, mix the other raw materials in the formula with the ball milled frit obtained in the pre-ball milling step of the frit, and then add water to the ball mill to obtain the glaze slurry. The addition of water The amount is 40-45% of the total weight of the raw materials;

[0048] Sieving to remove iron: sieving the glaze slurry obtained by ball milling through 160-200 mesh and removing iron;

[0049] Glazing: glaze the sanitary ceramic body, the thickness of the glaze layer is 0.8~1.2mm;

[0050] Drying: Put the glazed sanitary ceramics in a drying room at 50℃ for drying, and then transfer them to a drying ...

Example Embodiment

[0069] In Example 4, the amount of water added was 45% of the total amount of raw materials, the thickness of the glaze layer after 180 mesh sieving and iron removal and glazing was 0.8mm, and the firing temperature was 1205°C.

Example Embodiment

[0070] The amount of water added in Example 5 was 42% of the total amount of raw materials, the thickness of the glaze layer after 160 mesh sieving and iron removal and glazing was 1.2 mm, and the firing temperature was 1220°C.

[0071]

[0072] Wherein, the frit includes the following components in parts by weight: 66% SiO 2 , 4% Al 2 O 3 , 8%CaO, 12%Na 2 O, 1.0%MgO, 7.8%B 2 O 3 . The content of potassium oxide in the potash feldspar is 10%; the content of sodium oxide in the albite is 7%; the content of magnesium oxide in the burned talc is 30%.

[0073] The sanitary ceramic plates were prepared by using FFC glazes with high antifouling ability with different raw material formulations in the above Table 1 and the above-mentioned preparation methods, and the sanitary ceramic plates and the sanitary ceramic samples of the prior art were tested for dirt absorption and glossiness.

[0074] The test method of the dirt absorption test is: apply red ink or blue ink on a 10×10cm sanitary c...

Abstract

The invention discloses an FFC glaze with high stain resistance, an FFC sanitary ceramic and a preparation method of the FFC sanitary ceramic. The FFC glaze with high stain resistance comprises the following raw materials in parts by weight: 22-29 parts of quartz, 24-28 parts of potassium feldspar, 6-10 parts of wollastonite, 7-8 parts of zirconium silicate, 5-10 parts of kaolin, 0-5 parts of calcite, 5-7 parts of zinc oxide, 5-7 parts of aluminum oxide, 2-3 parts of frit, 4-8 parts of dolomite, 5-8 parts of calcined talc, 1-4 parts of barium carbonate and 0.2-0.5 part of sodium carboxymethylcellulose. According to the FFC glaze with high stain resistance, multi-alkali effect is utilized, barium carbonate is introduced, the use amount of calcined talc is increased, and the use amount of albite is reduced, so venting of a green body is more smooth, the porosity of a glaze surface is reduced, and microcracks of the glaze surface are reduced. Besides, the FFC glaze with high stain resistance also utilizes the principle of like dissolves like to increase the consumption of aluminum oxide and quartz, improve the bonding property of the blank and a glaze, and further reduce the microcracks on the glaze surface of the sanitary ceramic correspondingly.

Description

technical field [0001] The invention relates to the technical field of sanitary ceramics, in particular to an FFC glaze with high antifouling ability, FFC sanitary ceramics and a preparation method thereof. Background technique [0002] In the prior art, in order to improve the overall regularity of sanitary ceramics, ensure the original intention of the designer to the greatest extent, and improve the firing pass rate, FFC mud is generally used to make the body of sanitary ceramics. FFC is the abbreviation of Fine Fire Clay, which is a material used to prepare ceramics. FFC slurry can be used to prepare sanitary ceramic body by high-pressure grouting. The sanitary ceramic body prepared by FFC slurry is easy to dry and crack during drying, or easy to deform during firing, and most of the existing ceramic glazes contain such as high Sodium stone powder, potassium sodium feldspar and other low-temperature materials have low high-temperature resistance, which makes the body pr...
