Preparation method for graphene-like reinforced building ceramic glaze surface

Abstract

The invention relates to a preparation method for a graphene-like reinforced building ceramic glaze surface. The preparation method comprises the following steps: respectively adding 1 to 3% of high-temperature quenched graphite and 3 to 8% of a sugar or starch substance in terms of the mass of a building ceramic glaze material, applying a ball-milled glaze pulp onto a ceramic green body, carryingout drying, and carrying out sintering in a roller kiln so as to obtain a building ceramic tile. According to the invention, by utilization of a method of combining high-temperature quenching and mechanical ball-milling, a graphene oxide material with a single-layer or multi-layer structure is obtained, and is reduced into graphene-like under the action of high temperature, so the hardness and wear resistance of the building ceramic glaze surface are greatly improved. The product glaze surface provided by the invention has a microhardness of 726 to 755 Hv and reaches a wear-resistant grade of5 grades or more. The method provided by the invention has the advantages of simple and rapid operation, low cost, applicability to industrial scale production and good application prospects.

Description

technical field [0001] The invention belongs to the technical field of building ceramic materials, and in particular relates to a method for preparing a graphene-like reinforced building ceramic glaze. Background technique [0002] The building ceramics industry is an industry that consumes a lot of natural resources and energy. After decades of rapid development, raw materials, energy, land and other resources are becoming increasingly scarce. At present, the market can be divided into two types: glazed tiles and unglazed tiles. Unglazed tiles such as polished tiles consume a lot of energy and pollute a lot, but their surface hardness and wear resistance are good. Compared with unglazed tiles, glazed tiles have richer patterns, brighter colors and better decorative performance, but the glazed surface has lower wear resistance and is prone to scratches, which seriously restricts its application as floor tiles. The glaze hardness and wear resistance of glazed tiles mainly de...
