Problems solved by technology

For one-time firing products, the frit particles are distributed before firing. When the green body is not sintered, more solvent infiltrates into it will cause the strength of the mud body to deteriorate, the loss is high during transportation, and after firing, warping There are many deformation defects

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 discloses a green brick of a one-step sintered glass-ceramic composite board. The green brick comprises a green body layer and a glass-ceramic frit layer from bottom to top, wherein a hydrophobic layer is also arranged between the green body layer and the glass-ceramic frit layer; the glass-ceramic frit layer is formed by applying a glass-ceramic frit particle suspension liquid formed by mixing glass-ceramic frit particles and a frit particle binding agent on the surface of the hydrophobic layer; and the frit particle binding agent comprises the following components in percentage by mass: 3.8-4.8% of nonionic polyurethane associative thickener, 1.8-2.4% of attapulgite clay, 0.6-1% of defoaming agent, 0.6-1.6% of dispersing agent and the balance of solvent. By using the green brick, the glass-ceramic frit particles on the surface cannot be taken away by a draught fan at a preheating zone when being sintered, so that the waste is avoided, and the defect rate of glass-ceramic composite board products is reduced; and a hydrophobic agent is used in the scheme, so that the affect of a fixing agent to the strength of a green body can be avoided.

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...
