A brick adobe fired into a glass-ceramic composite board at one time

Abstract

The invention discloses a green brick of a one-step sintered glass-ceramic composite board. The green brick comprises a green body layer, a ground coat layer and a glass-ceramic frit layer from bottom to top and also comprises a fixing layer arranged on the surface of the glass-ceramic frit layer, wherein the fixing layer is formed by spraying a glass-ceramic frit particle fixing agent; and the glass-ceramic frit particle fixing agent comprises the following components in percentage by mass: 6.5-7.5% of nonionic polyurethane associative thickener, 3.2-4.4% of white carbon black, 1-1.5% of defoaming agent, 0.3-1.3% of dispersing agent and the balance of solvent. By using the green brick, 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.

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, a bottom glaze layer and a glass-ceramic layer from bottom to top. The glass-ceramic layer is generally composed of glass-ceramic frit particles. The adobe is pressed, glazed and printed. Finally, a layer of glass-ceramic frit particles will be placed on the surface of the bottom glaze layer, and then sent to the kiln...

[0021] Preparation of bottom glaze: Mix kaolin, quartz, potassium feldspar, albite, calcite, talc, dolomite, zinc oxide and zircon powder as raw materials for bottom glaze, add appropriate amount of water and 0.5% tripolymer Sodium phosphate, 0.3% methyl cellulose, ball milled into the chemical composition of SiO2: 50%, Al2O3: 20%, CaO: 9%, MgO: 2%, K2O: 2%, Na2O: 3%, ZnO: 4 %, ZrO2: 10%, and the fineness is 0.5% of the slurry bottom glaze on the 10,000-hole sieve for use. It should be noted that the green body powder and the preparation of the bottom glaze given here can be replaced by other formula components in the common knowledge, and can be applied to the preparation method of the single-firing glass-ceramic composite plate of the present invention. .

Sent into the kiln for firing at 1200°C, grinding and chamfering to obtain finished glazed tiles with uniform distribution and complete ice crystal texture, such as figure 2 The shown glass-ceramic composite board has a green body layer 1, an underglaze layer 2 and a glass-ceramic layer 5. It should be noted that the high-temperature transparent glass-ceramic frit particles selected in Example 1-1 are in the sintering process. Medium and stable spreading, forming a sil...
