Pure black glazed tile produced by using waste glaze slip and preparation method of pure black glazed tile
The invention provides a pure black glazed tile produced by using waste glaze slip and a preparation method of the pure black glazed tile in order to overcome the defects. On the basis of greatly unchanging the existing production process of glazed tiles, by optimizing the composition of ground coat and cover coat frits, the formula composition of the ground coat, the formula composition of the cover coat, regulating and optimizing ground coat and cover coat technological processes, especially the preferable section of green body types, the fired pure black glazed tile is pure in color, and the chromaticity (L *, a *, b *) value of an unprinted product is measured by a WSD-3C type whiteness colorimeter, wherein the L * (lightness) value is 6.25 to 6.43 and is close to the L * (lightness) value of 5.0 of standard carbon black, the a * (redness) value is -0.03 to 1.60, and the b * (yellowness) value is 0.15 to 0.18. The glazed tile is carbon black like pure black, the glaze has good quality, is moisturized and bright, and has no pinholes, glaze bubbles and other defects, and the glazed tile has strong decorative effect and aesthetic feeling; meanwhile, the technology has strong universality and is easily popularized in the industry.
