Double-layer low-water-absorption green brick capable of enhancing bonding strength of ceramic tile
The invention discloses a double-layer low-water-absorption green brick capable of enhancing the bonding strength of ceramic tiles, which comprises a green body layer and an isolation covering green body layer, the water absorption of the green body layer is less than 0.1%, and the water absorption of the isolation covering green body layer is 0.5-1%; the isolating and covering blank layer is formed by pressing and firing isolating and covering powder, and the grain composition of the isolating and covering powder is as follows: the screen residue of a 20-mesh screen is less than or equal to 7%, the screen residue of a 40-mesh screen is 65-80%, the screen residue of a 60-mesh screen is 88-96%, and the screen residue of a 100-mesh screen is more than or equal to 98%; the isolating and covering powder comprises the following chemical components in percentage by mass: 60 to 65 percent of SiO2, 19 to 22 percent of Al2O3, 0.7 to 1 percent of Fe2O3, 0.1 to 0.5 percent of TiO2, 0.2 to 0.7 percent of CaO, 2 to 2.6 percent of MgO, 2 to 3 percent of K2O, 1 to 1.6 percent of Na2O and 6.2 to 7.2 percent of ignition loss. According to the scheme, the isolation covering blank layer for enhancing the paving and bonding strength of the ceramic tile is additionally arranged at the bottom of the blank 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.
本发明公开了一种增强瓷砖粘结强度的双层低吸水率砖坯，包括坯体层和隔离遮盖坯层，所述坯体层的吸水率＜0.1％，所述隔离遮盖坯层的吸水率为0.5～1％；所述隔离遮盖坯层由隔离遮盖粉料压制并烧制而成，所述隔离遮盖粉料的颗粒级配为：20目筛网筛余≤7％、40目筛网筛余65～80％、60目筛网筛余88～96％和100目筛网筛余≥98％；且按照质量百分比，所述隔离遮盖粉料的化学成分包括SiO260～65％、Al2O319～22％、Fe2O30.7～1％、TiO20.1～0.5％、CaO 0.2～0.7％、MgO 2～2.6％、K2O 2～3％、Na2O 1～1.6％和烧失量6.2～7.2％。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坯层，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。
