A brick structure that burns into microcrystalline glass composite plates at a time

Abstract

The invention provides a green brick structure of a single fired glass ceramic composite board. The green brick structure comprises a green brick body layer, a ground coat layer and a glass ceramic frit layer from bottom to top, wherein a hydrophobic layer is also arranged between the green brick body layer and the ground coat layer; the glass ceramic frit layer is formed by applying microcrystalline frit particle suspension prepared by mixing glass ceramic frit particles with a frit particle binder to the surface of the ground coat layer; the frit particle binder comprises the following components by mass fraction: 5.5-6.5% of cellulosic thickening agents, 2.5-3.2% of white carbon black, 1.1-1.4% of defoaming agent, 1.2-1.8% of dispersing agents and the balance of solvents. By using the green brick, the glass ceramic frit particles on the surface can not be drawn away by a draught fan in a preheating zone during firing, thus avoiding waste and reducing the defect rate of glass ceramic composite board products.

Description

technical field

[0001] The invention relates to the technical field of architectural ceramics, in particular to an adobe structure of a glass-ceramic composite plate fired once. Background technique

[0002] Since the technology of glass-ceramic composite panel has been maturely applied, its technology has been continuously developed and innovated, and the product has become a high-grade decorative material in the market because of its transparent micro-crystalline frit particles and personalized decorative effect, and is well received by consumers. favorite.

[0003] The adobe structure of the once fired glass-ceramic composite board includes a green body layer and a glass-ceramic frit layer from bottom to top, and the glass-ceramic frit layer is generally composed of glass-ceramic frit particles, specifically, ceramic The powder is pressed to form an adobe, and then a layer of glass-ceramic frit particles is spread on the surface to form a glass-ceramic frit layer to obta...
