Unless otherwise specifically stated, various raw materials, reagents, instruments, equipment and the like used in the present invention are commercially available or can be prepared by existing methods.
The invention provides a frit for glaze, which comprises the following raw materials in parts by weight:
70-80 parts by mass of lepidolite roasting impregnation slag, 3-8 parts by mass of calcite and 3-5 parts by mass of quartz.
Lepidolite having a chemical formula of K ((Li)2-xAl1+x(Al2xSi4-2xO10)(F，OH)2) And) is a layered silicate mineral. In the general lithium extraction process, lepidolite and sulfate are mixed and then roasted at high temperature, metal ions in the sulfate are replaced by lithium ions through high-temperature ion replacement to form soluble lithium sulfate, and the soluble lithium sulfate is leached by water or dilute acid and then filtered to leave filtrate. Rubidium and cesium elements in the lepidolite remain in the slag.
The calcite can increase the refractive index of the glaze, improve the glossiness and improve the light transmission; meanwhile, calcium oxide generated by the heated decomposition of calcite can be used as a high-temperature fluxing agent to reduce the melting temperature and the high-temperature viscosity; and controlling 3-8 parts by mass of calcite to avoid devitrification of the glaze surface caused by excessive crystallization.
More easily-melted substances CaO and Na in lepidolite roasting leaching slag and calcite2O、K2O, MgO, and the like, to be fused with quartz and lepidolite to calcine silicate in the impregnation slag to generate transparent glass, so that the glaze is bright and the glossiness of the glaze is improved. Meanwhile, the mechanical strength of the glaze is increased, the hardness of the glaze is improved, and the ceramic crystal is wear-resistant, has good chemical stability and is not influenced by the erosion of acid.
Further, the raw materials also comprise the following components:
5-8 parts by mass of barium carbonate, 10-14 parts by mass of alumina, 1-3 parts by mass of potassium carbonate and 1-2 parts by mass of strontium carbonate. The raw materials contain 0.1-0.5 parts by mass of rubidium element, and the rubidium element is introduced through lepidolite roasting impregnation slag.
The addition of barium carbonate can reduce the melting temperature, so that when the prepared frit for glaze is used for ceramic processing, the temperature of the glaze can be consistent with that of a blank, and the glaze luster is increased.
The added alumina takes corundum as a main crystal phase, so that the mechanical strength and the hardness of the glaze frit are increased, the high-frequency dielectric loss is small, the high-temperature insulation resistance is high, and the chemical corrosion resistance and the thermal conductivity are good.
The addition of potassium carbonate reduces the melting temperature and increases the coefficient of expansion of the glaze frit.
When preparing the frit for glaze, the generation of air bubbles and pinholes on the ceramic glaze surface can be reduced by adding strontium carbonate.
The lepidolite roasting impregnation slag contains a certain amount of rubidium element, so that the color of the fired glaze is improved, and the prepared glaze has good glossiness and flatness; through sintering the lepidolite roasting infusion slag, the lepidolite roasting infusion slag can be utilized, and the environment is protected while waste is utilized; the lepidolite roasting leaching residue contains potassium element, calcium element, aluminum element and silicon element which can be utilized to prepare the frit for glaze.
The invention also provides a preparation method of the frit for glaze, which comprises the following steps:
s1, roasting the lepidolite leaching residue, calcite and quartz to generate a matrix;
specifically, according to the mass parts, 70-80 parts of lepidolite roasting impregnation slag, 3-8 parts of calcite and 3-5 parts of quartz are roasted at the temperature of 1000-1200 ℃ to generate a matrix.
The sulfate in the lepidolite roasting leaching residue can further generate silicate by being roasted as a matrix in advance, wherein sulfur element is evaporated.
Step S2, grinding the substrate produced in the step S1 into powder;
grinding into powder to facilitate melting in step S3, and mixing.
Step S3, melting the powder obtained in the step S2 to form a liquid substance;
specifically, 5-8 parts by mass of barium carbonate, 10-14 parts by mass of alumina, 1-3 parts by mass of potassium carbonate and 1-2 parts by mass of strontium carbonate are added to the powder obtained in the second step and are melted together to form a liquid substance.
Barium carbonate, aluminum oxide, strontium carbonate and potassium carbonate are added to increase various properties of the glaze frit. The water-soluble raw materials and the silicon dioxide can be melted together by melting and then water quenching.

to the powder were added 6g of barium carbonate, 12g of alumina, 2g of potassium carbonate, and 1.5g of strontium carbonate. Melting at 1100-1500 ℃ to form a liquid substance;
the liquid material obtained by melting is water-quenched to obtain a block-shaped glassy material, and then the glassy material is crushed into frit granules to prepare the frit for glaze.
The glaze frits prepared in examples 1 to 5 were added to a feldspar glaze in an amount of 30% by mass, ball-milled, applied to the surface of a green brick, and fired. Adopting GB/T4100-006 mirror image test, the test data is as follows:
| colour(s) | Flatness of | Wear resistance | |
| Example 1 | Uniformity | Smooth and has no obvious pores | 3 |
| Example 2 | Uniformity | Smooth and has no obvious pores | 3 |
| Example 3 | Uniformity | Smooth and has no obvious pores | 3 |
| Example 4 | Uniformity | Smooth and has no obvious pores | 3 |
| Example 5 | Uniformity | Smooth and has no obvious pores | 3 |
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the present specification and directly/indirectly applied to other related technical fields within the spirit of the present invention are included in the scope of the present invention.
