[0055] Further, the present invention also proposes the preparation method of the above-mentioned protective glaze suitable for firing in a low-temperature fast-fired kiln, comprising the following steps:

[0056] S1) According to the weight percentage calculation, respectively weigh 5-10% of potassium feldspar, 30-40% of albite feldspar, 1-3% of calcined kaolin, 2-3% of zinc oxide, 4-8% of washed kaolin, and 8% of calcined talc. -12%, 4-6% strontium carbonate, 4-6% calcite, 10-15% alumina and 5-8% dolomite, mix evenly and add an appropriate amount of hydration slurry to check that the total content of alumina meets the setting After the range, the mixture is prepared;

[0057] S2) putting the mixture into a ball mill for wet ball milling to obtain a slurry;

[0058] S3) passing the slurry through a vibrating sieve, and removing iron with a strong magnetic field, so as to obtain the glaze slurry of the protective glaze.

[0059] The above-mentioned preparation process is sim...

[0068] 1. The protective glaze suitable for firing in a low-temperature fast-firing kiln of each embodiment and each comparative example is prepared according to the following steps:

[0069] S1) According to the weight percentage calculation, respectively weigh 5-10% of potassium feldspar, 30-40% of albite feldspar, 1-3% of calcined kaolin, 2-3% of zinc oxide, 4-8% of washed kaolin, and 8% of calcined talc. -12%, 4-6% strontium carbonate, 4-6% calcite, 10-15% alumina and 5-8% dolomite, mix evenly and add an appropriate amount of hydration slurry to check that the total content of alumina meets the set After the range, the mixture is prepared;

[0070] S2) putting the mixture into a ball mill for wet ball milling to obtain a slurry;

[0071] S3) pass the slurry through a 160-mesh vibrating sieve, and remove iron with a strong magnetic field, so as to obtain the glaze slurry of the protective glaze;

[0072] In step S2), the flow rate of wet ball milling is 90-120 seconds, an...

Abstract

The invention discloses a protective glaze suitable for firing in a low-temperature fast firing kiln and a ceramic tile and a preparation method thereof, and the protective glaze comprises the following chemical components of raw materials in percentage by weight: SiO2, Al2O3, CaO, MgO, K2O, Na2O and ignition loss; the firing temperature of the protective glaze in a low-temperature fast firing kiln is 1199-1230 DEG C, and the firing time is 50-55 minutes; the tension of the protective glaze effectively prevents bubbles generated in the cover glaze layer, the ink jet layer and the pressed green body from breaking through the glaze layer; according to the ceramic tile fired in the low-temperature fast firing kiln, the protective glaze is applied above the ink jet layer between the cover glaze and the polished glaze, the thickness is small, bubbles can be effectively prevented from rising, and the effect of protecting the ink jet layer and the glaze surface from generating air holes and concave glaze defects is achieved; the preparation method of the protective glaze suitable for firing in the low-temperature fast-firing kiln is simple in process and does not cause obvious increase of the manufacturing cost of the product.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a protective glaze suitable for firing in a low-temperature fast-fired kiln, ceramic tiles and a preparation method thereof. Background technique [0002] The reasons for the surface defects of ceramic tiles are as follows: the adobe contains carbonate, and there are closed pores or open pores on the surface of the adobe. When the glaze is poured on the surface glaze, the closed pores or open pores on the surface glaze are closed. When firing, the carbonate decomposes and gasifies to produce a large amount of gas and gathers into bubbles. After the gas in the closed pores or open pores accumulates to a certain amount, bubbles will also form. Defects that form pinholes and concave glazes. [0003] In order to improve the energy-saving and environmental protection performance of ceramic brick production, the ceramic brick kiln of the prior art has been upgraded, the maximum...
