Preparation method of full-body granite ceramic tile

Abstract

The invention belongs to the field of ceramic tiles, relates to a preparation method of a full-body granite ceramic tile and aims to solve the problems of non-uniform coloring, long production periodand high production cost of an existing full-body granite ceramic tile. The following technical schemes are adopted: the preparation method comprises the following steps that: S1, raw materials are crushed and ball-milled, the crushed and ball-milled material is sieved, and iron is removed, so that slurry A is prepared; S2, the slurry A in the S1 is subjected to powder formation, pressing and pre-drying, so that a brick blank B can be obtained; S3, the brick blank B in the S2 is sequentially subjected to ground coat spraying, protective glaze spraying, pattern spraying and dry granular glaze spraying treatment to obtain a brick blank C, the caliber of dry granular glaze spraying nozzles is 2.8-3.0 mm, each nozzle is of a spiral structure, the multiple nozzles are connected with the same glaze suction pipe, and a quarter ball valve is installed on the glaze suction pipe; and S4, the brick blank C in the S3 is subjected to material throwing and drying, the treated brick blank C is put into a firing kiln so as to be fired and molded, so that a sample D can be obtained; and S5, the sample D in the S4is processed, inspected and classified. The full-body granite ceramic tile is uniform in coloring, short in production period and low in production cost.

Description

technical field [0001] The invention relates to the technical field of tiles, in particular to a method for preparing whole-body granite tiles. Background technique [0002] Granite tiles are commonly used decorative materials in people's lives, and they are widely used in outdoor gardens, building exterior walls, tooling engineering and other fields. [0003] When the existing granite tiles are processed, the preparation technology of mold + high temperature glaze, inkjet + dry glaze + mica sheet is usually used. But in actual production, there are the following problems: 1. When spraying glaze and coloring, it is easy to have uneven coloring and discoloration, and the product quality is poor; 2. When spraying dry glaze, the particle size of conventional ceramic tile spray dry Above 120 mesh, use a high-pressure glaze spray cabinet, the nozzle diameter is between 0.26-1.3mm, and the ultra-coarse dry particle (30-60 mesh) glaze has a large particle size, which is easy to ca...
