Non-radiative opal fritted glaze for ceramic tiles and preparation method of non-radiative opal fritted glaze

Abstract

The invention discloses non-radiative opal fritted glaze for ceramic tiles. The non-radiative opal fritted glaze is composed of the following raw materials in percentage by weight: 4%-6% of K2O, 0-1% of Na2O, 10%-20% of CaO, 0-6% of MgO, 0-10% of ZnO, 2%-7% of B2O3, 3%-8% of Al2O3, 50%-60% of SiO2 and 3%-10% of TiO2. The ingredients of the glaze formulation are designed and adjusted again, no raw material zirconium silicate bringing radiative elements to the glaze product is added, the novel glass liquation technology principle is adopted and raw materials containing no radiative ingredient are introduced so as to obtain ceramic glaze having no harmful radiation and achieving a required whiteness effect.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a radiation-free opalescent frit glaze for ceramic tiles and a preparation method thereof. Background technique

[0002] Glazed bricks are bricks whose surface has been glazed. According to different raw materials, it can be divided into two categories: pottery glazed tiles and porcelain glazed tiles. Ceramic glazed tiles are fired from clay, with high water absorption and relatively low strength. Porcelain glazed tiles are fired from china clay, with low water absorption and relatively high strength. It should be noted that the comparison of water absorption and strength mentioned above is relative, and some ceramic glazed tiles have better water absorption and strength than porcelain glazed tiles.

[0003] According to the difference of luster, glazed tiles can be divided into smooth glazed tiles and matte glazed tiles. Glazed tiles are the most common type of br...
