The invention discloses a warm eye-protection matte glaze for building ceramic tiles, and a preparation technology thereof. The preparation technology comprises the following steps: (1) weighing clay,feldspar, quartz, talcum, dolomite, limestone, borax, zirconium silicate, zinc oxide, alumina, barium carbonate and strontium carbonate according to the chemical composition range, crushing the weighed materials to form 180-350 mesh particles, mixing the particles, sintering the obtained mixture at 1480-1580 DEG C to form a glassy melt, and quenching the glassy melt with water to obtain a matte frit for the ceramic tile glaze; and (2) adding clay raw materials and a glaze slip performance regulator to the frit, and performing full wet ball-milling to obtain a matte glaze slip. The compositionof the formula is slightly changed, so the glaze obtained after sintering has the advantages of high strength, high wear resistance, high aging resistance and long service life; the glaze is flat, fine and smooth, is free of pinholes, and has silky or velvet gloss, and the glossiness of the glaze is 3-5 DEG less than that of existing products, so the glaze makes people have soft, quiet and comfortable eye-protection feeling; and the tile matte glaze has tender and soft hand feeling, and is warm.
