Problems solved by technology

[0006] The above methods all use a concave-convex mold to make the surface of the green body form a texture, but because the mold inevitably has artificial traces and does not have a natural random decorative effect, the decorative effect of the produced ceramic tiles is dull, stiff and unnatural; At the same time, if you want to obtain different texture patterns, you need to change the mold, resulting in increased production costs; it cannot be well combined with other decorative patterns

Abstract

The invention relates to the technical field of construction ceramics, and in particular discloses a ceramic tile with embossed textures, which is formed by processing a blank and glaze. The ceramic tile is characterized in that: the glaze is prepared from the following basic components in percentage by weight: 5 to 20 percent of frit, 5 to 15 percent of magnesium oxide, 5 to 15 percent of alumina, 10 to 30 percent of camwood segments, and 20 to 50 percent of bentonite. The invention also discloses a method for manufacturing the ceramic tile with embossed texture, which comprises the following steps of: preparing the blank and glaze; forming a tile blank; applying the glaze; firing; and cooling to a normal temperature. According to the ceramic tile with embossed textures disclosed by the invention, the formation of embossed textures does not require an embossed die, and a natural smooth, continuously changing and non-repeated embossed texture surface decorating effect is represented on the manufactured ceramic tile without artificial trace by virtue of the glaze prescription and process parameter design.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a ceramic brick with concave-convex texture. Background technique [0002] Ceramic tiles are plate-shaped or block-shaped ceramic products produced by clay and other inorganic non-metallic raw materials through molding and sintering processes. They are used to decorate and protect walls and floors of buildings and structures. one of the materials. With the improvement of people's living standards, new requirements are constantly put forward for the decorative effect of ceramic tiles. More and more people hope that ceramic tiles can present concave-convex textures imitating natural leather grains and wood grains. [0003] CN102029644A discloses a production process of wood-grain antique bricks, which includes the following steps: (1) preparing blanks, surface glazes and floral glazes; (2) forming blanks in mold bricks to form green bricks, and the mold bricks are p...
