Abstract

The invention provides a method for firing photoluminescence fluorescence glaze ceramic through a roller kiln, and belongs to the technical field of building ceramic production. The method comprises the following steps: mixing dolomite, quartz, europium oxide, yttrium oxide and aluminum hydroxide, adding water, carrying out ball milling, drying and calcining to obtain a photoluminescence fluorescent powder material, mixing kaolin, talc, pyrophyllite, a medium-temperature frit and the photoluminescence fluorescent powder material, adding water, and carrying out ball milling to obtain a fluorescent glaze material; mixing kaolin, feldspar and quartz, adding water, and carrying out ball milling, drying, powdering and compression molding to obtain a green body; and finally, applying the fluorescent glaze material to the green body, and firing at a high temperature in the roller kiln to obtain the photoluminescence fluorescence glaze ceramic. According to the photoluminescence fluorescence glaze ceramic produced by the method, the compatibility of the glaze and the green body is good, red fluorescence is emitted, the fluorescence intensity can be regulated and controlled, and the requirements in the fields of anti-counterfeiting marks, real-time display and light response can be met.

Description

technical field [0001] The invention provides a method for firing photoluminescent glazed ceramics through a roller kiln, which belongs to the technical field of building ceramics production. Background technique [0002] With the development of society, people's pursuit of the quality of architectural ceramics is getting higher and higher. While considering excellent decorative properties, functional elements have also received attention, such as optical properties, including long afterglow, luminescence properties or photoluminescent real-time fluorescent ceramics have attracted the attention of researchers, producers and consumers in recent years. The materials selected for long afterglow ceramic glazes are mainly obtained from aluminate, silicate, aluminosilicate or titanate-based spinel materials doped with rare earths, which are not suitable for high-temperature firing (generally no more than 950 ℃), cannot be used in the roller kiln production of architectural cerami...
