Problems solved by technology

[0004] In the firing process, the frit has to go through the process of melting, crystallization, and crystal growth, and different textures are formed through the growth of crystals. The traditional fabric technology uses powder and granular materials to pile up the fabric, making it difficult for glass crystals to break through the particles after melting. The border, therefore, grows a pattern with a single pattern, less changes, and a poor sense of hierarchy

Abstract

The invention discloses a flaky frit microcrystallite glass ceramic composite plate and a preparation method thereof. The preparation method comprises the following steps: distributing materials, namely, distributing not less than two layers of frits having different shapes on green brick and spraying a fixing agent for fixation, wherein at least one layer of frits is formed by irregular flaky frits; sintering; and polishing. The flaky frits are introduced to a colored microcrystallite glass decoration layer, tape casting is generated when the flaky frit is fused, control of sintering temperature and other process control are further combined, and thus the defects that particle border cannot be broken through when the particle frit glass crystallizes, pattern is single, change is less and layering is bad are overcome, and the obtained product is peculiar in figure, daedal in color effect, cloud-covered, strong in three-dimensional layering and lifelike in stone texture.

Description

technical field [0001] The invention relates to a sheet-like frit glass-ceramic composite plate and a manufacturing method thereof. Background technique [0002] Glass-ceramic composite board is a new type of composite board that combines glass-ceramics on the surface of ceramic vitrified tiles. It is a high-tech product in the field of construction. Stone texture, brightly colored layers, uncanny appearance decoration effect, and unpolluted, easy to clean, and excellent internal physical and chemical properties. In addition, it has stronger weather resistance, weather resistance, and no radioactivity than stone. Favored by foreign high-end building materials market. [0003] The early glass-ceramic composite panels were manufactured by double firing, that is, the green body was bisque-fired first, and then the color material was printed on the biscuit-fired green body by screen printing or roller printing. Cloth transparent frit; finally carry out secondary firing to obta...
