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

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 3

[0047] Components of per 100kg frit particle binder: 4kg of non-ionic polyurethane associative thickener (NaeWoiKorea., Ltd. company, model HIRESOL85), attapulgite clay content is added in the following table 3, polyether type GPE is eliminated Foaming agent (purchased from Hangzhou Feier Chemical Industry Co., Ltd.) 1kg, sodium tripolyphosphate 1.6kg, and the balance is water.

[0048] The frit granules of 375kg green ice crystal effect (purchase from Quincy Carroby Glaze Company, fineness 100 orders) are added in the 125kg frit granule binder that embodiment 3 makes, mix uniformly, get frit granule Suspension, frit particle solid content 75%, no visible bubbles, left for 5 days, flow rate and stratification phenomenon are shown in Table 3.

Embodiment 3-00

[0050] Add 375kg of frit granules of green ice crystal effect (purchased from Quincy Carroby Glaze Company, fineness 100 mesh) into 125kg of viscous water slurry prepared by sodium carboxymethyl cellulose, mix well to get frit granules Suspension, frit particle solid content 75%, left for 5 days, flow rate and stratification phenomenon are shown in Table 3.

[0051] Table 3 Effect of attapulgite clay content on the delamination phenomenon of suspension

[0052]

[0053] 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 susp...

Abstract

The invention discloses a green brick of a one-step sintered glass-ceramic composite board. The green brick comprises a green body layer and a glass-ceramic frit layer from bottom to top, wherein the glass-ceramic frit layer is formed by applying a glass-ceramic frit particle suspension liquid formed by mixing glass-ceramic frit particles and a frit particle binding agent on the surface of the green body layer; and the frit particle binding agent comprises the following components in percentage by mass: 3.8-4.8% of nonionic polyurethane associative thickener, 1.8-2.4% of attapulgite clay, 0.6-1% of defoaming agent, 0.6-1.6% of dispersing agent and the balance of solvent. By using the green brick, the 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 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...
