Abstract

The invention relates to a producing method of neoceramic glass-ceramics compound board for architecture decoration, including: having the intact glass board as mother glass, having the ceram dried body or ceramic biscuit body as ceram base, laminating the intact mother glass board on the ceramic base, after heating, the upper mother glass being crystallized and integrating with the lower ceramic base to produce neoceramic glass-ceramics compound board. The invention is characterized in that it includes following steps: 1) preparing the ceramic base; 2) preparing the mother glass board; 3) preparing the compound board, i.e. laminating the intact mother glass board on the ceramic base, after heating, making the rough board of the neoceramic glass-ceramics compound board; 4) grinding and polishing to form a finished product. The invention has advantages such as no air vent bug, a low cost of raw material, a simple manufacturing art and effectively conquers the disadvantages of current glass articles sintering method.

Description

technical field [0001] The invention relates to a preparation method of a glass-ceramic-ceramic composite plate, which is mainly used for architectural decoration. Background technique [0002] Glass-ceramics has excellent properties such as compact structure, high mechanical strength, wear resistance, corrosion resistance, and strong weathering resistance, and can be used as high-grade building decoration materials. However, the manufacturing cost of the glass-ceramic plate of the whole body is very high; and only using the glass-ceramic as the decorative layer, it is fused on the ceramic substrate to make a glass-ceramic-ceramic composite plate, which is beneficial to a large extent. The production cost is reduced, and it is beneficial to large-scale industrial production. At present, the preparation technology of glass-ceramic-ceramic composite board used in actual production is mainly "glass-ceramic-ceramic composite board preparation technology by glass particle sinter...
