Problems solved by technology

[0003] The adobe of the glass-ceramic composite board fired at one time includes a green body layer, a bottom glaze layer and a glass-ceramic layer from bottom to top. The glass-ceramic layer is generally composed of glass-ceramic frit particles. The adobe is pressed, glazed and printed. Finally, 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 transported into the kiln, it will pass through a low negative pressure pre-tropical zone. The glass-ceramic frit particles are easy to be sucked away because of their light weight, resulting in the lack of many glass-ceramic frit particles on the surface layer. It greatly affects the quality and aesthetics of the glass-ceramic composite board, and the qualified yield is not high
[0004] At present, people spray a layer of adhesive after distributing the glass-ceramic frit, but the commonly used adhesives (such as carboxymethyl cellulose aqueous solution or other similar glues) have poor bonding effect, or are not suitable for use. It is used in the production of glass-ceramic composite panels, and the solvent in the existing adhesive is easy to infiltrate into the body, and the strength of the mud body will decrease under the immersion in the solvent, so the loss during transportation is large, and the warping deformation defect after burning also more

preparation example Construction

[0021] Preparation of the bottom glaze: mix kaolin, quartz, potassium feldspar, albite, calcite, talc, dolomite, zinc oxide, zircon powder, and pyrophyllite with a thickness of less than 100 meshes as the bottom glaze raw material, add appropriate amount of water and 0.5% Sodium tripolyphosphate and 0.3% methyl cellulose are ground into a ball mill. 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 fineness of the glaze slurry is 0.5% of the slurry bottom glaze on the 10,000-hole sieve for use. The amount of pyrophyllite in the bottom glaze is 3-5% of the total mass, because pyrophyllite has good water absorption and can absorb the solvent in the adhesive to prevent it from infiltrating into the brick body too much, thereby avoiding the subsequent transportation of the brick brick. Loss, usually, adopting the above method can reduce the green body conveying loss by 2-3%. It should be noted t...

Embodiment 1-1

[0026] The high-temperature transparent glass-ceramic frit particles (purchased from Quincy Carloby Glaze Company, 80 mesh) cloth are placed on the surface of the base glaze layer of the green body through the printing process, and then the microcrystalline prepared in one layer of embodiment 1 is sprayed. The glass frit particle fixative is sent into the kiln for firing at 1200°C, and the edges are ground and chamfered to obtain a finished glazed tile with uniform distribution and complete ice crystal texture. It should be noted that the high-temperature transparent glass-ceramic frit particles selected in Example 1-1 spread stably during the sintering process, forming a silver-white ice crystal texture pattern on the glaze layer, and the glass-ceramic frit particles can pass through The color glaze company purchases and obtains, and similar frit products can also realize this scheme.

Embodiment

[0034] Example Group 2 - Effect of Attapulgite Clay Content on the Viscosity of Polyurethane Fixatives

[0035] The component of every 100kg polyurethane fixative: nonionic polyurethane associative thickener (Nae Woi Korea., Ltd. company, model HIRESOL85) 4.3kg, attapulgite clay content is added as follows table 2, polyether type GPE Defoamer (purchased from Hangzhou Feier Chemical Industry Co., Ltd.) 0.6kg, sodium tripolyphosphate 1.2kg, the balance is diethylene glycol ether.

[0036]The preparation method of the above-mentioned polyurethane fixing agent comprises the following steps: 1) dissolving the nonionic polyurethane associative thickener in water, and stirring evenly; 2) adding attapulgite clay, and mixing evenly; 3) adding polyether-type GPE The defoamer and sodium tripolyphosphate were stirred evenly to obtain a polyurethane fixative, and the flow rate of the prepared polyurethane fixative was tested.

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, and further comprises a fixing layer arranged on the surface of the glass ceramic fruit layer, wherein the fixing layer is formed by spraying a glass ceramic frit particle fixing agent, the ground coat layer contains 3%-5% of pyrophyllite according to mass percent, and the glass ceramic frit particle fixing agent comprises the following components in percentage by weight: 3.8-4.8% of a nonionic polyurethane associated thickener, 1.8-2.4% of attapulgite clay, 0.6-1% of a defoamer, 0.6-1.6% of a dispersing agent and the balance of a solvent. When the green brick is used, a 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, a bottom glaze layer and a glass-ceramic layer from bottom to top. The glass-ceramic layer is generally composed of glass-ceramic frit particles. The adobe is pressed, glazed and printed.
