Problems solved by technology

Then send the above into the kiln for firing. When transported into the kiln, it will pass through a low negative pressure pre-tropical zone. Some small glass-ceramic frit particles that are placed on the top layer are easily sucked away due to their light weight. , resulting in the lack of a lot of glass-ceramic frit particles on the surface layer, the flatness of the adobe is not high after firing, and pinholes or dissolution holes appear, which greatly affects the quality and aesthetics of the glass-ceramic composite board. The yield rate is not high

Embodiment 1-1

[0033] A method for preparing a once-fired transparent glass-ceramic composite board, comprising the following steps:

[0034] A. Green body stamping and forming: After the green body powder (fineness is 150 degrees) and micropowder powder (fineness is 150 degrees) are layered, punched into a green body with a bottom blank layer and a micropowder layer, wherein the micropowder layer The thickness is 1 / 2 of the thickness of the bottom layer, dry;

[0035] B. Spray a layer of hydrophobic layer: spray a layer of modified polyvinyl alcohol water repellent (purchased from Jinan Yuekai Chemical Co., Ltd.) on the surface of the green body;

[0036] C, applying glass-ceramic frit particle suspension: the glass-ceramic frit particle (purchasing from Quincy Carloby Glaze Company, fineness 70 orders) of 375kg silvery-white ice crystal effect is added to embodiment group 1 and makes In 125kg of frit particle binder, mix evenly to obtain glass-ceramic frit particle suspension, the solid c...

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...
