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

preparation example Construction

[0030] 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.

[0031] It should be noted that the preparation of green body powder, micropowder formula components and bottom glaze given here can be replaced by other formula components in the common knowledge, and all can be applied to the composite glass-ceramics of the present invention. In the preparation method of the plate. The bottom glaze mainly serves as a covering function, so the make-up soil with high whiteness is usually selected, and its expansion and contraction coefficient during firing is between the g...

Embodiment 1

[0035] Components of each 100kg of glass-ceramic frit particle fixative: 5.0kg of hydroxyethyl cellulose (purchased by Guangzhou Moke Building Materials Technology Co., Ltd.), 2.5kg of attapulgite, 1.1kg of polymethylsiloxane, silicone modified Sodium phosphate 1.7kg, the balance is water.

[0036] The preparation method of the above-mentioned frit granule binder comprises the following steps: a) dissolving hydroxyethyl cellulose in water, and stirring evenly; b) adding polymethylsiloxane and organic silicon-modified sodium phosphate, and stirring evenly; c) Add attapulgite and the remaining water solvent, and stir evenly to obtain a frit particle binder. The measured flow rate is 26.8s (30°C, coated with -4 cups). It should be noted that the organosilicon-modified sodium phosphate can be replaced by sodium polyacrylate or sodium hexametaphosphate as a dispersant, and this solution can also be realized.

Embodiment 1-1

[0038] A method for preparing a once-fired transparent glass-ceramic composite board, comprising the following steps:

[0039] A. Green body stamping and forming: After the green body powder (fineness is 150 mesh) and micropowder powder (fineness is 150 mesh) 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;

[0040] B. Spray a layer of water-repellent layer 2: Spray a layer of silicone water-repellent on the surface of the green body;

[0041] C. Glaze printing;

[0042] D, applying glass-ceramic frit particle suspension: the glass-ceramic frit particle (purchasing from Quincy Carloby glaze company, fineness 100 orders) of 375kg silver-white ice crystal effect is added 125kg that embodiment 1 makes In the frit particle binder, mix evenly to get glass-ceramic frit particle suspension, the solid content of glass-ceramic frit particles is 75%, n...

Abstract

The invention relates to a green brick of a single-firing 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, wherein a hydrophobic layer is further arranged between the green body layer and the ground coat layer, the glass ceramic frit layer is formed in a manner that a glass ceramic frit particle suspension liquid formed by blending a glass ceramic frit particle and a frit particle binder is painted on the surface of the ground coat layer, the frit particle binder comprises the following components of in percentage by weight: 5.0-6.0% of a cellulose thickener, 2.0-2.8% of attapulgite, 1.1-1.4% of a defoamer, 1.2-1.8% of a dispersing agent and the balance of a solvent. When the green brick is used, the glass ceramic frit particle on the surface cannot be taken away by an air draught in a preheating zone in the firing, so that the waste is avoided, and the defect rate of a product of the glass ceramic composite board 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...
