preparation example Construction

[0027] Preparation of the bottom glaze: kaolin, quartz, potassium feldspar, albite, calcite, talc, dolomite, zinc oxide, zircon powder, pyrophyllite with a thickness of less than 100 meshes are mixed by ball milling as raw materials for the bottom glaze, and an appropriate amount of water and 0.5 % sodium tripolyphosphate, 0.3% methyl cellulose, the chemical composition of the bottom glaze is SiO2: 50%, Al2O3: 20%, CaO: 9%, MgO: 2%, K2O: 2%, Na2O: 3%, ZnO: 4%, ZrO2: 10%, and the slurry bottom glaze whose fineness is 0.5% of the 10,000-hole sieve is for use.

[0028] The pyrophyllite in the bottom glaze has good water absorption, which can alleviate the deformation of the green body caused by the solvent in the suspension liquid penetrating into the green body. Usually, the pyrophyllite is 3-5% of the mass of the dry material of the bottom glaze.

[0029] It should be noted that the preparation of green body powder, micropowder formula components and bottom glaze given here can...

Embodiment 1-1

[0034] The glass-ceramic frit particle of 375kg silver-white ice crystal effect (purchase from Quincy Caroby Glaze Company, fineness 70 orders) is added in the frit particle binder of 125kg that embodiment group 1 makes, mix homogeneously , to obtain glass-ceramic frit particle suspension, the solid content of glass-ceramic frit particles is 75%, no visible bubbles, the flow rate is 45.3s (30 ℃, coated with -4 cups), and there is still no stratification after the suspension is placed for 5 days , it can be seen that the frit particle binder of the present invention still has good stability after mixing with the glass-ceramic frit particles. It should be noted that the glass-ceramic frit particles with silver-white ice crystal effect selected in Example 1-1 spread during the sintering process, forming the effect of silver-white ice crystal flowers on the glaze layer, and the glass-ceramic frit particles It can be purchased through the color glaze company, and similar frit produ...

Embodiment 2

[0045] Components of every 100kg frit granule binder: nonionic polyurethane associative thickener (NaeWoiKorea., Ltd. company, model HIRESOL85) content is added as shown in Table 1, attapulgite clay 2.0kg, polyether type GPE Defoamer (purchased from Hangzhou Feier Chemical Industry Co., Ltd.) 1kg, sodium tripolyphosphate 1.6kg, and the balance is water.

[0046] 350kg has the glass-ceramic frit particle of milky white ice crystal effect (purchasing from Quincy Carroby Glaze Company, fineness 110 orders) is added in the frit particle binder of 150kg that embodiment 2 makes, mix homogeneously, A glass-ceramic frit particle suspension was obtained. The solid content of the glass-ceramic frit particles was 70%, and there were no visible bubbles. The suspension was left for 5 days. See Table 2 for the flow rate and stratification.

Abstract

The invention provides a preparation method of a single fired glass ceramic composite board. The preparation method comprises the following steps: A, green body punch forming; B, glazing and printing, wherein the glaze contains 3-5% of pyrophyllite by mass; C, spraying of a layer of glass ceramic frit suspension, and spraying a layer of glass ceramic frit suspension onto the surface of the green body in the step B, wherein the glass ceramic frit suspension is prepared by mixing glass ceramic frits with polyurethane binders and the polyurethane binders are prepared from the following components by mass fraction: 3.8-4.8% of nonionic polyurethane associative thickening agent, 1.8-2.4% of attapulgite clay, 0.6-1% of defoaming agent, 0.6-1.6% of dispersing agents and the balance of solvents; D, firing, namely feeding the green body into a kiln and firing at a temperature of 1150-1250 DEG C; and E, polishing and edging processing, thus obtaining the finished product of the glass ceramic composite board. The preparation method has the beneficial effects that the adverse effects of a preheating zone of the kiln on the adsorption effects of the glass ceramic frits can be avoided and the product yield can be increased.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a preparation method of a once-firing glass-ceramic composite plate. Background technique [0002] The glass-ceramic composite board is a new type of composite board that combines a layer of glass-ceramic on the surface of the ceramic tile. Because the surface is a glass-ceramic layer, it is completely antifouling and easy to clean and maintain. At present, glass-ceramics frits are mainly covered with a certain thickness of glass-ceramics frits (particle size is 15-150 mesh) on the body surface or glaze surface by means of cloth, and a layer of adhesive is sprayed to fix the particles. On the surface of the green body, after firing, the glazed surface is reprocessed. The quality of the glass-ceramic frit directly determines the flatness of the brick and the decorative effect of the brick. The binder used in the prior art is only ordinary glue and The water is mixed acc...
