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 the bottom glaze: mix kaolin, quartz, potassium feldspar, albite, calcite, talc, dolomite, zinc oxide and zircon powder with a thickness of less than 100 meshes as the bottom glaze raw material, 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 it is better to choose makeup soil with higher whiteness, and its expansion and contractio...

Embodiment 1

[0035] Components of each 100kg of glass-ceramic frit particle fixative: 5.5kg of hydroxyethyl cellulose (purchased by Guangzhou Moke Building Materials Technology Co., Ltd.), 2.5kg of white carbon black, 1.1kg of polymethylsiloxane, silicone modified Sodium phosphate 1.7kg, the balance is ethylene glycol.

[0036] The preparation method of the above-mentioned frit particle binder comprises the following steps: a) dissolving hydroxyethyl cellulose in ethylene glycol and stirring evenly; b) adding polymethylsiloxane and organosilicon-modified sodium phosphate, Stir evenly; c) Add white carbon black and the remaining ethylene glycol solvent, stir evenly to obtain a frit particle binder, and measure its flow rate to be 25.7s (30°C, coat -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 provides a green brick structure of a single fired glass ceramic composite board. The green brick structure comprises a green brick body layer, a ground coat layer and a glass ceramic frit layer from bottom to top, wherein a hydrophobic layer is also arranged between the green brick body layer and the ground coat layer; the glass ceramic frit layer is formed by applying microcrystalline frit particle suspension prepared by mixing glass ceramic frit particles with a frit particle binder to the surface of the ground coat layer; the frit particle binder comprises the following components by mass fraction: 5.5-6.5% of cellulosic thickening agents, 2.5-3.2% of white carbon black, 1.1-1.4% of defoaming agent, 1.2-1.8% of dispersing agents and the balance of solvents. By using the green brick, the glass ceramic frit particles on the surface can not be drawn away by a draught fan in a preheating zone during firing, thus avoiding waste and reducing the defect rate of glass ceramic composite board products.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to an adobe structure 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 structure of the once fired glass-ceramic composite board 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 The powder 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 to obta...
