Problems solved by technology

The traditional method is to apply glaze on the surface of wall and floor tiles, but the glaze layer is generally thin and has poor wear resistance, and it also needs to increase the process steps of glaze making, glazing, and even firing glaze. The process is very complicated and the production cost is also high.

Abstract

The invention discloses a coal gangue ceramic wall and ground brick and a preparation method thereof. The coal gangue ceramic wall and ground brick is compounded from a base body layer and a surface layer. The base body layer comprises the following raw materials in percentage by weight: 30-68 percent of coal gangue, 0-25 percent of pulverized fuel ash, 15-30 percent of quartz, 15-30 percent of feldspar and 2-8 percent of bentonite. The surface layer comprises the following raw materials in percentage by weight: 40-55 percent of kaolin, 20-35 percent of quartz, 20-30 percent of feldspar and 3-8 percent of bentonite, wherein the pigment which is 0-8 percent of the weight of the material of the surface layer is additionally added into the material of surface layer. The coal gangue ceramic wall and ground brick has a double-layer structure compounded from the base body layer and the surface layer, and the working surface (surface layer) of the brick is lighter than the base body layer and may be white, light yellow, red or other colors set according to the demand, thereby overcoming the defects of deeper color and single hue of the coal gangue ceramic wall and ground brick manufactured by the conventional method and expanding the application field.

Description

technical field [0001] The invention relates to a ceramic wall and floor tile, in particular to a coal gangue ceramic wall and floor tile, and also relates to a preparation method of the coal gangue ceramic wall and floor tile. Background technique [0002] Kaolin is one of the main raw materials for preparing ceramic wall and floor tiles. In recent years, the resource reserves of kaolin have been decreasing day by day, and the price has been rising year by year, which has led to an increase in the cost of ceramic wall and floor tiles. Therefore, it is imperative to explore and develop alternatives to kaolin. [0003] Coal gangue is solid waste discharged during coal mining and washing, which not only occupies a large amount of land, but also causes great pollution to the surrounding environment. Coal gangue is composed of kaolinite, montmorillonite, quartz and other minerals as well as some rare metal elements and organic carbon, and its chemical composition is mainly SiO ...
