Glaze composition for high hardness glaze layer and manufacturing method of ceramic floor tile having excellent scratch resistance using the composition

摘要

The present invention provides a crystallized glaze composition for forming the crystallized glaze layer in a ceramic floor tile including a substrate layer, an embossed layer provided above the substrate layer, and a crystallized glaze layer provided on the upper surface of the base layer, wherein the limestone powder 10 By weight of feldspar powder, 5 to 15% by weight of feldspar powder, 10 to 20% by weight of alumina powder, 20 to 40% by weight of glass frit, 10 to 28% by weight of kaolin powder, 0.1 to 8% And 0.5 to 7 parts by weight of TiO ₂ powder plasma-treated with respect to 100 parts by weight of the glaze material, and a process for producing a high hardness ceramic floor tile using the same / RTI According to the present invention, a high hardness crystallized glaze layer having excellent surface hardness value and high abrasion resistance can be formed on the surface of the ceramic floor tile.
