Ecological energy-saving ceramic glazed tile and preparation method thereof

Abstract

The invention provides an ecological energy-saving ceramic glazed tile and a preparation method thereof, belonging to the field of novel building materials. The ceramic glazed tile is prepared from a preform body and a glaze through integrated molding and sintering. The preform body is prepared through the following steps: mixing a preform body main material, a pore forming agent and a binder according to a mass ratio of 55-85 to 5-20 to 10-25); carrying out homogenization; and then carrying out ageing for at least 24 hours. The glaze is prepared through the following steps: mixing a glaze main material and a binder according to a mass ratio of 85-90 to 10-15; carrying out homogenization; and then carrying out ageing for at least 24 hours. Since the ecological energy-saving ceramic glazed tile provided by the invention uses industrial waste like fly ash and red mud, the ceramic glazed tile has low cost and realizes ecological environmental protection; due to usage of a serrated special transition layer structure, the defect of poor bonding performance of the preform body and the glaze in a traditional glazing process is overcome; the preform body and the glaze are integratedly molded, so the preparation method is simple; the ceramic glazed tile is prepared through one-shot low temperature sintering, so cost can be significantly reduced; and the ceramic glazed tile has multiple integrated excellent properties like decoration performance, resistance to permeation and water seepage, and self heat insulation performance.

Description

technical field [0001] The invention belongs to the field of new building materials, and in particular relates to a preparation method of ecological and energy-saving ceramic glazed bricks. Background technique [0002] With the advancement of urbanization and new rural construction, the demand for ceramic glazed tiles for interior and exterior walls is increasing year by year. Unfortunately, the most widely used ceramic glazed tiles for interior and exterior walls currently have dense ceramic substrates under the enamel layer. , although it has the performance of impermeability and low water absorption of the substrate, it can no longer meet the requirements of modern building ecology and energy conservation, and the raw materials used in production are mostly natural resources such as clay and limestone, and the consumption is huge.

[0002] With the advancement of urbanization and new rural construction, the demand for ceramic glazed tiles for interior and exterior walls is increasing year by year. Unfortunately, the most widely used ceramic glazed tiles for interior and exterior walls currently have dense ceramic substrates under the enamel layer. , although it has the performance of impermeability and low water absorption of the substrate, it can no longer meet the requirements of modern building ecology and energy conservation, and the raw materials used in production are mostly natural resources such as clay and limestone, and the consumption is huge

In the molding process of the brick body, although the blank and the glaze are used twice, and the molding is pressed once, there is no special treatment for the transition area between the blank and the glaze, and it is completely dependent on the combination of the blank and the glaze in the micro-area during the firing process. Diffusion of components leads to weak bonding between the blank and the glaze after firing, and the defect of plaque peeling often occurs under the condition of a little external force
