High-flatness glazed brick and preparation method thereof
The invention discloses a high-flatness glazed brick which comprises a green body layer and a ground coat layer, wherein the ground coat layer is positioned at the top of the green body layer; the green body layer is prepared from the following chemical components in percentage by mass: 18 to 20 percent of Al2O3, 55 to 65 percent of SiO2, 3.2 to 3.6 percent of K2O, 1.8 to 2 percent of Na2O and 1 to 1.5 percent of MgO; the expansion coefficient of the green body layer is smaller than that of the ground coat layer, and the difference value between the expansion coefficient of the ground coat layer and the expansion coefficient of the green body layer is smaller than 30. According to the high-flatness glazed brick, improvement of flatness of the glazed brick is facilitated. According to the preparation method of the high-flatness glazed brick, technological parameters of the green brick in the pressing and firing process are matched with performance parameters of the high-flatness glazedbrick, and the flatness of the glazed brick can be further improved.
本发明公开了一种高平整抛釉砖，包括坯体层和底釉层；所述底釉层位于所述坯体层的顶部；按照质量百分比，所述坯体层包括以下化学成分：Al2O318～20%、SiO255～65%、K2O3.2～3.6%、Na2O1.8～2%和MgO1～1.5%；所述坯体层的膨胀系数小于所述底釉层的膨胀系数，且所述底釉层的膨胀系数与所述坯体层的膨胀系数之间的差值小于30。本技术方案提出的一种高平整抛釉砖，有利于提高抛釉砖的平整度。进而提出的一种高平整抛釉砖的制备方法，使砖坯在压制和烧制过程中的工艺参数与高平整抛釉砖的性能参数相匹配，能进一步提高抛釉砖的平整度。
