Low-water-absorption ceramic tile capable of enhancing bonding strength of ceramic tile
The invention discloses a low-water-absorption ceramic tile capable of enhancing the bonding strength of the ceramic tile, which comprises a green body layer and an isolation covering glaze layer, the isolation covering glaze layer is located at the bottom of the green body layer, and the water absorption of the green body layer is less than 0.1%; the isolating and covering glaze layer is prepared from the following raw materials: kaolin, calcium-magnesium-sodium frit, corundum powder and titanium dioxide; the isolating and covering glaze layer comprises the following chemical components in percentage by mass: 35%-40% of SiO2, 40%-45% of Al2O3, 0.1%-0.3% of Fe2O3, 6%-10% of TiO2, 1.3%-2.3% of CaO, 2%-3% of MgO, 0.1%-0.4% of K2O, 3.5%-4% of Na2O and 0.5%-2% of ignition loss. According to the scheme, the isolation covering glaze layer for enhancing the paving and bonding strength of the ceramic tile is additionally arranged at the bottom of the green body layer, so that the hollowing and falling phenomena formed in the paving and using processes of the existing low-water-absorption ceramic tile can be effectively reduced, and the defects in the prior art are overcome; meanwhile, the isolating and covering glaze layer also has excellent covering power and whiteness.
本发明公开了一种增强瓷砖粘结强度的低吸水率瓷砖，包括坯体层和隔离遮盖釉层，所述隔离遮盖釉层位于所述坯体层的底部，且所述坯体层的吸水率＜0.1％；所述隔离遮盖釉层的原料包括高岭土、钙镁钠熔块、刚玉粉和钛白粉；且按照质量百分比，所述隔离遮盖釉层的化学成分包括SiO235～40％、Al2O340～45％、Fe2O30.1～0.3％、TiO26～10％、CaO 1.3～2.3％、MgO 2～3％、K2O 0.1～0.4％、Na2O 3.5～4％和烧失量0.5～2％。本方案通过在坯体层底部增设一增强瓷砖铺贴粘结强度的隔离遮盖釉层，能有效降低现有低吸水率瓷砖在铺贴和使用过程中所形成的空鼓和脱落现象，以克服现有技术中的不足之处；同时，隔离遮盖釉层还具有优异的遮盖力和白度。
