Silica sol reinforced ultra-white thin ceramic plate and preparation method thereof
The invention discloses a silica sol reinforced ultra-white thin ceramic plate and a preparation method thereof. The green body of the silica sol reinforced ultra-white thin ceramic plate is prepared from the following raw materials in percentage by mass: 20% to 25%of clay, 50% to 60%of ultra-white sand, 3% to 6%of calcined talc, 3% to 6%of calcined aluminum oxide, 3% to 24%of feldspar and 10% to 20%of silica sol. According to the invention, the silica sol is introduced into the formula of the thin ceramic plate, so that on the basis of realizing high whiteness, the wet blank strength of the ceramic plate is effectively improved, the damage of the ceramic plate before the drying process is reduced, and the mechanical property of the thin ceramic plate finished product can be enhanced in situ by virtue of the reaction of the silica sol and other blank raw materials in the firing process.
本发明公开一种硅溶胶增强的超白薄型陶瓷板及其制备方法。所述硅溶胶增强的超白薄型陶瓷板的坯体原料包括：以质量百分比计，粘土20‑25%、超白砂50‑60%、烧滑石3‑6%、煅烧氧化铝3‑6%、长石3‑24%、硅溶胶10‑20%。本发明提出在薄型陶瓷板的配方中引入硅溶胶，在实现高白度的基础上，有效增加陶瓷板的湿坯强度，减少陶瓷板在干燥工序前的破损，还可以借助硅溶胶与其他坯体原料在烧成过程中反应原位增强薄型陶瓷板成品的力学性能。
