Problems solved by technology

[0005] In order to solve the problem that the layering of the decorative surface of the existing glass-ceramic composite bricks is not rich enough, the present invention introduces high-calcium raw materials and uses the crystal nucleating agent in reverse to control the crystallization area and transparency and / or translucency. The staggered distribution of regions provides a production method for glass-ceramic composite bricks with rich layers and good decorative effects

Abstract

The invention discloses a production method of a microcrystalline glass-ceramic composite brick. The production method comprises the following steps: (1) preparing a high-calcium raw material; (2) preparing a low-viscosity glass frit and a high-viscosity glass frit; (3) preparing powder of a green microcrystalline glass-ceramic composite brick through a conventional method; (4) preparing a microcrystalline glass-ceramic composite brick substrate from the powder of the green microcrystalline glass-ceramic composite brick prepared by the step (3) through a conventional method; (5) preparing a microcrystalline glass-ceramic composite brick; and (6) post-processing. The microcrystalline glass-ceramic composite brick prepared by the production method disclosed by the invention, through staggered distribution of crystallization regions and transparent and / or semitransparent regions, changes an original monotonous texture that has only crystallization patterns on the entire surface, and the brick is richer in pattern layering sense and better in decoration effect; the production method disclosed by the invention is lower in sintering temperature, shorter in sintering cycle, and capable of greatly reducing energy consumption, relieving emission and saving manufacturing cost; and the prepared composite brick has fewer surface pores, good anti-fouling performance and high wear resistance.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a production method of a glass-ceramic composite brick. Background technique [0002] Glass-ceramics has excellent properties such as compact structure, wear resistance, corrosion resistance, high mechanical strength, and strong weathering resistance, and can be used as high-grade building decoration materials. However, the whole body of glass-ceramics has high energy consumption, high pollution and high cost during manufacture; while glass-ceramics is used as the surface finish layer, or a mixture of glass-ceramics and ceramics is used as the surface finish layer, and then ordinary ceramics As the bottom support layer, made of glass-ceramic composite bricks is conducive to greatly reducing energy consumption, reducing emissions, saving manufacturing costs, and is easy for large-scale industrial production. [0003] The basic production process of glass-ceramic composi...
