Low-water-absorption ceramic tile capable of improving bonding strength and preparation method of low-water-absorption ceramic tile
The invention discloses a preparation method of a low-water-absorption ceramic tile capable of improving the bonding strength of the ceramic tile. The preparation method comprises the following steps: A, preparing a green body layer; b, applying isolation covering glaze at the bottom of the green body layer, wherein the isolation covering glaze comprises the following chemical components in percentage by weight: 39%-44% of SiO2, 34%-48% of Al2O3, 0.1%-0.3% of Fe2O3, 0.05%-0.25% of TiO2, 1.5%-2.5% of CaO, 2%-3.5% of MgO, 0%-0.6% of K2O, 3.7%-4.3% of Na2O and 0.5%-2% of ignition loss; and C, the bottom of the isolation covering glaze layer is coated with tile prime slurry in a roller coating mode, the low-water-absorption ceramic tile capable of improving the bonding strength of the ceramic tile is obtained after the isolation covering glaze layer is put into a kiln to be fired, and the specific gravity of the tile prime slurry is 1.04-1.1. According to the scheme, the isolation covering glaze layer for improving the tile paving bonding strength is additionally arranged at the bottom of the green body layer, so that the bonding strength of the tile during paving can be improved, a certain isolation effect can also be achieved, the isolation covering glaze layer is used for partially replacing existing tile prime slurry, the occurrence of rods and nails in the firing process is avoided, and the service life of the tile is prolonged. The bonding strength and the paving efficiency of the ceramic tile can be further improved.
本发明公开了一种提高瓷砖粘结强度的低吸水率瓷砖的制备方法，包括以下步骤：A、准备坯体层；B、在坯体层的底部布施隔离遮盖釉，隔离遮盖釉的化学成分包括SiO239～44％、Al2O344～48％、Fe2O30.1～0.3％、TiO20.05～0.25％、CaO 1.5～2.5％、MgO 2～3.5％、K2O 0～0.6％、Na2O 3.7～4.3％和烧失量0.5～2％；C、在隔离遮盖釉层的底部辊涂砖底浆，入窑烧制后得到提高瓷砖粘结强度的低吸水率瓷砖，且砖底浆的比重为1.04～1.1。本案通过在坯体层底部增设一提高瓷砖铺贴粘结强度的隔离遮盖釉层，除了可以提高瓷砖在铺贴时的粘结强度，还能起到一定的隔离作用，将其用于部分替代现有的砖底浆，以避免烧制过程中棒钉的出现，有利于进一步地提高瓷砖的粘结强度和铺贴效率。
