Glazed ceramic tile and preparation method thereof
The invention discloses a glazed ceramic tile and a preparation method thereof. The glazed ceramic tile is prepared by processing a blank material and glaze, and the blank material comprises the following compositions in percent by weight: 50-75% of anaerobic digestion sludge, 10-25% of clay, 5-15% of wollastonite, and 5-10% of talcum. The glazed ceramic tile preparation method comprises preparing blank and glaze, forming a green body, drying, biscuiting, glazing the green body, performing glaze firing on the green body, and the like. The green body of the glazed ceramic tile is high in strength and small in shrinkage degree when being biscuited, the biscuiting temperature scope of the green body is expanded, and phenomena that the green body surface foams, generates black hearts and is reduced in compressive strength and the like because of too large ignition loss are effectively avoided. The glazed ceramic tile preparation method enables the glazed ceramic tile surface to be solid, flat, free of black heart phenomenon, and high in strength, and also the preparation method is simple and easily controllable in technology, high in yield and high in production efficiency, and production cost is effectively reduced.
