Abstract

The invention relates to a green brick of a monofired glass ceramic composite plate. The green brick comprises a green body layer and a glass ceramic frit layer from bottom to top, a water repellent layer is further arranged between the green body layer and the glass ceramic frit layer, and the glass ceramic frit layer is formed in the way that a glass ceramic frit particle suspension liquid formed by mixing glass ceramic frit particles and a frit particle adhesive is applied to the surface of the water repellent layer; the frit particle adhesive comprises the following components by mass percent: 6.5-7.5 percent of a nonionic polyurethane associative thickener, 3.2-4.4 percent of silica, 1-1.5 percent of a defoamer, 0.3-1.3 percent of a dispersant and the balance of solvent. The glass ceramic frit particles of the surface of the green brick structure are not taken away by a blower at a preheating zone during firing, so that waste is avoided and the defect rate of the glass ceramic composite plate product is reduced.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a brick adobe made 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 of the glass-ceramic composite board fired at one time 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 powder The material 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 t...
