Problems solved by technology

Most of the near-infrared reflective opacifying glazes use titanium dioxide as the opacifying agent. Studies have found that titanium dioxide also has a good near-infrared light reflection function, but because titanium dioxide mainly exists in the rutile crystal form during the low-temperature glaze firing process, the glaze surface turns yellow. , unable to prepare high-quality glazed tiles

Abstract

The invention belongs to the technical field of architectural ceramics, and particularly discloses a ceramic glaze with infrared reflection, a light glazed exterior wall tile and a preparation method of the light glazed exterior wall tile. The ceramic glaze contains calcite, quartz, titanium dioxide and titanite frit, and the titanite frit is prepared from the following raw materials: calcite, titanium dioxide, quartz and wollastonite; the light glazed exterior wall tile comprises a light green body layer, a sealing cover glaze layer, a near-infrared reflecting glaze layer and a transparent protective glaze layer from bottom to top, wherein the near-infrared reflecting glaze layer is formed by firing ceramic glaze. Ceramic glaze with a near-infrared light reflection function is applied to the light glazed exterior wall tile, a tile body is endowed with good near-infrared light reflection performance, meanwhile, the sealing cover glaze layer is added between the light green body layer and the near-infrared reflection glaze layer, gas generated by a high-temperature reaction in the light green body layer can be effectively sealed under the glaze layer, and the light glazed exterior wall tile has the good near-infrared light reflection performance. The defects of glaze pinholes, glaze cracks and the like are prevented, and the function of the near-infrared reflection glaze layer and the surface quality of the transparent protection glaze layer are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of architectural ceramics, and in particular relates to a ceramic glaze with infrared reflection, a light-weight glazed exterior wall brick and a preparation method thereof. Background technique [0002] Lightweight ceramic tiles have the characteristics of porosity, low density, sound insulation, and heat insulation. They are a new generation of green, energy-saving and environmentally friendly building materials. They can meet the needs of decoration while reducing the load on the floor. Therefore, they can be widely used in interior and exterior walls of buildings. . At present, most lightweight ceramic tiles are foamed with a foaming agent to form a certain pore structure, so as to achieve the purpose of reducing the volume density of ceramic tiles. At the same time, low-temperature foaming materials are mostly added to lightweight ceramic tiles, resulting in lower firing temperatures and a large amount...
