Low-water-absorption ceramic tile capable of improving bonding strength of ceramic tile and preparation method thereof
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, the bottom of the green body layer is placed downwards, and isolation covering glaze is sprayed to the bottom of the green body layer; the isolation covering glaze comprises the following chemical components in percentage by weight: 39 to 44 percent of SiO2, 44 to 48 percent of Al2O3, 0.1 to 0.3 percent of Fe2O3, 0.05 to 0.25 percent of TiO2, 1.5 to 2.5 percent of CaO, 2 to 3.5 percent of MgO, 0 to 0.6 percent of K2O, 3.7 to 4.3 percent of Na2O and 0.5 to 2 percent of ignition loss; c, polishing and grinding the surface of the green body layer; and D, the bottom of the isolation covering glaze layer is coated with brick bottom slurry with the specific gravity being 1.04-1.1 in a roller coating mode, and the isolation covering glaze layer is put into a kiln to be fired. 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 be achieved, and the isolation covering glaze layer is used for partially replacing existing tile bottom slurry so as to avoid the occurrence of bars and nails in the firing process; 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、坯体层的底部朝下放置，在坯体层的底部喷涂隔离遮盖釉；隔离遮盖釉的化学成分包括SiO2 39～44％、Al2O3 44～48％、Fe2O3 0.1～0.3％、TiO2 0.05～0.25％、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、对坯体层的表面进行抛磨；D、在隔离遮盖釉层的底部辊涂比重为1.04～1.1的砖底浆，入窑烧制。本方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。
