Anti-slip protective glaze, anti-slip stain-resistant ceramic tile and preparation method of anti-slip stain-resistant ceramic tile

The invention discloses an anti-slip protective glaze, an anti-slip stain-resistant ceramic tile and a preparation method thereof, and relates to the technical field of ceramic tiles. Wherein the anti-skid protective glaze is prepared from the following components in parts by weight: 6 to 10 parts of calcined kaolin, 4 to 8 parts of corundum, 30 to 45 parts of high-bismuth frit, 15 to 24 parts of potassium feldspar, 12 to 20 parts of albite, 6 to 10 parts of calcined apatite, 6 to 10 parts of calcite, 10 to 15 parts of barium carbonate and 4 to 6 parts of zinc oxide. The anti-skid protective glaze has good fluidity, can well fill surface gaps of anti-skid ceramic tiles, effectively prevents the gaps from hiding dirt, and can further form a fine crystal structure to improve the anti-skid performance. 本发明公开了一种防滑保护釉、防滑耐污陶瓷砖及其制备方法，涉及陶瓷砖技术领域。其中，所述防滑保护釉的制备原料按重量份数计，包括以下组分：煅烧高岭土6～10份、刚玉4～8份、高铋熔块30～45份、钾长石15～24份、钠长石12～20份、煅烧磷灰石6～10份、方解石6～10份、碳酸钡10～15份、氧化锌4～6份。所述防滑保护釉具有良好的流动性，能够很好地填充防滑瓷砖的表面缝隙，有效避免缝隙藏污，此外，防滑保护釉还能进一步形成细小
