Wide-color-gamut inkjet glaze decorated ceramic floor tile and production process thereof

Abstract

The invention relates to the technical field of ceramic tiles, and in particular relates to a wide-color-gamut inkjet glaze decorated ceramic floor tile and a production process thereof. A floor tile billet comprises the following components in parts by weight: 40-75 parts of a cooked porcelain material, 0-38 parts of porcelain stone, 20-30 parts of clay and 0-5 parts of a mineralizing agent; and a production method comprises the following steps: firstly performing conventional processes such as wet-process ball-milling, spray drying and dry-pressing molding on architectural ceramics to prepare a billet, by taking titanium series engobe as a ground glaze, combining engobe with a low-temperature ink-jet ink composition of interior wall tiles to perform inkjet decoration, and performing firing in a roller hearth kiln under the conditions that the firing temperature is 1030-1100 DEG C and the firing cycle is 35-60min to prepare a finished product, wherein the water absorption rate of the finished product is 0-3%, and the quality of the product can meet the national standard requirements. The wide-color-gamut inkjet glaze decorated ceramic floor tile disclosed by the invention has the beneficial effects that energy conservation and emission reduction can be achieved, and the firing temperature can be reduced by 50-100 DEG C compared with that of the same category of products; the technology bottleneck that titanium series opacified engobe can be yellowed when being applied in the floor tiles in a conventional high-temperature process can be effectively solved; and the color gamut range of an inkjet decorative layer of a glaze decorated ceramic tile can be significantly broadened.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a wide-color-gamut ink-jet glazed ceramic floor tile and a production process thereof. Background technique [0002] At present, the general firing temperature of floor tiles in the building ceramics industry is between 1180 and 1220°C, and the firing cycle is between 60 and 85 minutes. The gas generated by high-temperature firing will form acid rain, greenhouse effect, and destroy the ozone layer; for enterprises, It means that the energy consumption is very large and the cost increases; at the same time, under the condition of high-temperature firing, the synthesis reaction of ceramic pigments is generally restricted. As an innovation of ceramic surface decoration technology after silk screen and rubber roller, inkjet printing technology has been widely used in products such as matte, glossy, fully polished glaze, and porcelain tiles. However, the current inkjet...

Problems solved by technology

[0009] ②Increase the forming pressure; generally speaking, increasing the forming pressure can reduce the firing temperature of ceramic tiles to a certain extent and reduce the water absorption rate. However, the increase in pressure is not unlimited, and it often brings about the improvement of the performance requirements of the forming equipment and the energy consumption. The corresponding increase increases the blackness of the product in the process, so it belongs to the auxiliary cooling method

[0010] ③Reduce the milling fineness of the formula; with the reduction of the milling fineness of the ceramic formula raw materials, the solid-liquid phase reactivity of ceramic products increases, and the firing temperature decreases. It is not economical to increase in multiples at the geometric exponential level

However, when the titanium-based make-up soil is above 1100°C, TiO 2 Easy to generate rutile, making the glaze surface light yellow
