Dry granular glaze, matte ceramic tile and preparation method of dry granular glaze
The invention provides dry granular glaze, a matte ceramic tile and a preparation method of the matte ceramic tile. The dry granular glaze is prepared from the following chemical components in percentage by mass: 50 to 60 percent of SiO2, 15 to 20 percent of Al2O3, 3.5 to 5.5 percent of K2O, 1.5 to 3.0 percent of Na2O, 0.05 to 0.1 percent of TiO2, 0.05 to 0.1 percent of Fe2O3, 0.1 to 0.5 percent of MgO, 3 to 5 percent of CaO, 5 to 10 percent of BaO, 3 to 5 percent of SrO, 3 to 4 percent of ZnO, 0.01 to 0.05 percent of Rb2O and 0.05 to 0.1 percent of B2O3. According to the dry granular glaze provided by the invention, the components and the contents of the components in the dry granular glaze are adjusted and optimized, so that a glaze surface prepared by taking the dry granular glaze as a raw material is low in glossiness and has a matte effect; the formula is designed by matching SiO2 and Al2O3, the content of SiO2 and Al2O3 is limited within a certain range, the glaze surface prepared from the dry granular glaze as a raw material has fine granular sensation after high-temperature firing, the particle appearance is round and fine, and the overall touch hand feeling is smoother, so that the phenomenon of dirt residue caused by rough surface of the ceramic tile can be avoided; a certain amount of ZnO is introduced into the dry granular glaze, so that the color development capability of the glaze surface of the ceramic tile can be improved, the color development effect of the glaze surface is more stable, and the permeability of the glaze surface is good.
本发明提供一种干粒釉、哑光瓷砖及其制备方法。按照质量百分比计算，该干粒釉的化学组成包括SiO250～60％、Al2O315～20％、K2O 3.5～5.5％、Na2O 1.5～3.0％、TiO20.05～0.1％、Fe2O30.05～0.1％、MgO 0.1～0.5％、CaO 3～5％、BaO 5～10％、SrO 3～5％、ZnO 3～4％、Rb2O 0.01～0.05％、B2O30.05～0.1％。本发明提供的干粒釉通过对干粒釉中各组分及其含量进行调整和优化，使得采用该干粒釉作为原料制备的釉面光泽度低，具有哑光效果；采用SiO2与Al2O3进行搭配设计配方并将其含量限定在一定的范围内，采用干粒釉作为原料制备的釉面在经过高温烧成后其表面具有细小颗粒感，且颗粒外观圆润细腻，整体触摸手感更加光滑，进而能够避免瓷砖表面粗糙而出现污垢残留的现象；在干粒釉中引入一定量的ZnO可提高瓷砖釉面的发色能力，使得釉面发色效果更加稳定，釉面通透性好。
