Problems solved by technology

[0003] The adobe structure of the once fired glass-ceramic composite board includes a green body layer, a bottom glaze layer and a glass-ceramic frit layer from bottom to top. The glass-ceramic frit layer is generally composed of glass-ceramic frit particles, and the adobe After forming the body layer by pressing and glazing and printing, a layer of glass-ceramic frit particles will be placed on the surface of the bottom glaze layer, and then sent to the kiln for firing. When it is transported into the kiln, it will go through a low negative pressure preliminary In the tropics, some small glass-ceramic frit particles on the uppermost layer are easily absorbed due to their light weight, resulting in the lack of many glass-ceramic frit particles on the surface layer, and the flatness of the bricks after firing is not high. , and there are pinholes or dissolution holes, which greatly affect the quality and aesthetics of the glass-ceramic composite board, and the qualified yield is not high

Embodiment 1-1

[0027] 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

[0038] 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.

[0039]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.

Embodiment 3-00

[0049] The frit granules of 375kg green ice crystal effect (purchased from Quincy Carloby Glaze Company, fineness 100 mesh) are added in the 125kg viscous water slurry prepared by sodium carboxymethyl cellulose, mix well, get frit granules Suspension, frit particle solid content 75%, left for 5 days, flow rate and stratification phenomenon are shown in Table 3.

[0050] Table 3 Effect of attapulgite clay content on the delamination phenomenon of suspension

[0051]

[0052] It can be obtained from Table 3 that the viscosity value of the viscous water slurry formulated with sodium carboxymethyl cellulose is not high, which cannot effectively prevent the glass-ceramic frit particles from being sucked away by low negative pressure, and there is bubble phenomenon, which is different from that of glass-ceramic The suspension after mixing the frit particles cannot be stored for a long time. In addition, the addition of attapulgite clay increases the thickening efficiency of the ...

Abstract

The invention relates to a green brick of a monofired glass ceramic composite plate. The green brick structure comprises a green body layer, a ground glaze layer and a glass ceramic frit layer from bottom to top, wherein the glass ceramic frit layer is formed in the way that microlite frit particle suspension liquid formed by mixing the glass ceramic frit particles and a frit particle adhesive is applied to the surface of the ground glaze layer; the ground glaze layer comprises 3-5 mass percent of pyrophyllite, and the frit particle adhesive comprises the following components by mass percent: 3.8-4.8 percent of a nonionic polyurethane associative thickener, 1.8-2.4 percent of attapulgite clay, 0.6-1 percent of a defoamer, 0.6-1.6 percent of a dispersant and the balance of a solvent. The glass ceramic frit particles of the surface of the green brick structure are not taken away by a blower at a preheating zone during firing, so that waste is avoided and the defect rate of the glass ceramic composite plate product 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 structure of the once fired glass-ceramic composite board includes a green body layer, a bottom glaze layer and a glass-ceramic frit layer from bottom to top. The glass-ceramic frit layer is generally composed of glass-ceramic frit particles, and the adobe After forming the body layer by pressing and glazing and printing, a layer of glass-ceramic frit particles will be placed on the surface of the bo...
