Bright glaze ceramic tile and preparation method thereof

Abstract

The invention provides a bright glaze ceramic tile and a preparation method thereof. The preparation method comprises the following steps: performing compression moulding on a preform body, and performing drying in a roller kiln to form a bright glaze ceramic tile green body; applying a ground coat onto the surface of the ceramic tile green body by a glaze pouring process to form a bottom glaze layer; forming a pattern decorative layer on the surface of the ceramic tile green body by ink jet printing; applying a bright glaze onto the surface of the pattern decorative layer to form a bright glaze layer to obtain a semi-finished product of the bright glaze ceramic tile; and performing quick firing on the semi-finished product of the bright glaze ceramic tile in a kiln to obtain the bright glaze ceramic tile, wherein the firing cycle is 45-70 min, and the firing temperature is not greater than 1210 DEG C. According to the method provided by the invention, the powder is pressed to form thegreen body, so that the surface of the green body is flat; the ground coat is applied to cover a color of the green body, so that the flatness and pattern decorative effect of a glaze surface are improved; the bright glaze is applied, so that the gloss and flatness of the glaze surface is improved; and high-temperature one-time quick firing molding is performed, so that the firing cycle and a water absorption rate of the product are reduced, and the strength of the product is enhanced.

Description

technical field [0001] The invention relates to the field of building ceramic production, in particular to a bright glazed ceramic tile and a preparation method thereof. Background technique [0002] Architectural ceramic tiles can be divided into glazed tiles and unglazed tiles according to whether they are glazed or not. Glazed ceramic tiles can be divided into bright glaze and matte glaze according to the gloss intensity of the glaze surface, and some with very low gloss are called matte glaze. In the current ceramic tile market, bright ceramic tiles are the main products. These products are mainly marble-like glazed tiles, polished tiles, real stone and other types of tiles. The surface gloss of polished tiles is high, and it is also a bright tile, but this type of variety is not glazed, and the luster is formed by directly cutting the surface of the fired ceramic tile body and polishing; full glazed, real stone, and porcelain tiles Ceramic tiles such as ceramic tiles,...

AI Technical Summary

Problems solved by technology

The process of this kind of product is relatively complicated, and generally requires two firing processes of green body biscuit firing and glaze firing, otherwise the glaze surface will have unevenness, glaze pinholes and other defects, which will affect the appearance of ceramic tiles. Effect

The second-fired ceramic tiles have poorer glaze bonding than once-fired ceramic tiles, and the heat energy consumption is higher, which is uneconomical and is not conducive to environmental protection and energy saving.
