Problems solved by technology

[0003] However, during the firing process of lightweight ceramic tiles, a large amount of gas is generated, so that the glaze layer is prone to defects such as glaze pinholes and glaze bubbles, which seriously affects the appearance and antifouling performance of lightweight ceramic tiles.
The existing method of secondary firing is to discharge most of the gas through biscuit firing of the body first, and then glaze for secondary firing. Although it can reduce the incidence of defects such as glaze pinholes and glaze bubbles, although in The existing lightweight ceramic tile production process adds additional production links, which increases the difficulty of production; moreover, due to the different firing temperatures of the two firings, a large amount of gas will be generated in the body during the heating process, and glaze pinholes and glaze bubbles will appear There is a higher probability of defects such as

Abstract

The invention relates to the technical field of ceramic glazed bricks, and provides a preparation method of a light high-strength pure-color glazed brick, which comprises the following steps: preparing green body slurry, preparing a green brick, applying ground glaze, applying overglaze, drying, sintering and polishing. According to the invention, a foaming material is added in the formula of the green body and the formula of the ground glaze, so that the obtained glazed brick has the advantages of porous sponge body structure, many gaps, light weight and high strength, has excellent sound insulation and heat insulation performance, and has ultra-high wear resistance, and the wear resistance reaches the 5 grade.

Description

technical field [0001] The invention relates to the technical field of ceramic glazed tiles, in particular to a preparation method of light-weight, high-strength solid-color glazed tiles. Background technique [0002] With its superior performance and decorative effect, ceramic tiles are favored by more and more consumers, and are widely used in people's daily life. Ceramic tiles are the most important part of interior decoration, and the difference in their performance directly affects the scope of application. Lightweight ceramic tiles have a porous sponge structure, low density, sound insulation, and heat insulation. They are a new generation of energy-saving and environmentally friendly architectural ceramic tiles. They meet the decoration needs without increasing the floor load, so they are widely used use. [0003] However, a large amount of gas is produced in the firing process of lightweight ceramic tiles, so that the glaze layer is prone to defects such as glaze p...
