Ceramic tile green body, preparation process thereof, fast-fired ceramic tile and preparation process of fast-fired ceramic tile
The invention relates to the technical field of ceramic tiles, in particular to a ceramic tile green body and a preparation process thereof, and a fast-fired ceramic tile and a preparation process thereof.The ceramic tile green body is prepared from, by mass, 60%-69% of SiO2, 14%-20% of Al2O3, 0.5%-3% of Fe2O3, 2%-4% of CaO2, 0.5%-1.5% of MgO, 2%-4% of K2O, 0.5%-2% of Na2O and 3%-7% of L.O.I; caO is at least partially introduced from wollastonite, and the wollastonite accounts for 5-7% of the total mass of the raw materials. According to the scheme, wollastonite with relatively low content is introduced into the raw materials of the green body, so that the firing temperature can be reduced, the firing period can be shortened, the production cost of the ceramic tile can be reduced, and the inner part of the thick brick can be uniformly fired without an interlayer phenomenon. Meanwhile, the reasonable calcium content and potassium-sodium content ratio are determined, so that the prepared ceramic tile has the characteristic of low water absorption rate.
本发明涉及陶瓷砖技术领域，尤其涉及一种瓷砖坯体及其制备工艺、快烧陶瓷砖及其制备工艺，瓷砖坯体按质量百分比计，按质量百分比计，其化学组成包括：SiO260‑69％、Al2O314‑20％、Fe2O30.5‑3％、CaO2‑4％、MgO0.5‑1.5％、K2O2‑4％、Na2O0.5‑2％和L.O.I3‑7％；所述CaO至少部分由硅灰石引入，且所述硅灰石占原料总质量的5‑7％。本方案在坯体原料中引入含量较低的硅灰石，便可以实现降低烧成温度，缩短烧成周期，降低了陶瓷砖的生产成本，还可以保证厚砖的内部烧制均匀，不存在夹层现象。同时确定合理的钙含量以及钾钠含量配比，使制得的陶瓷砖具有低吸水率的特性。
