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

Embodiment 1-1

[0024] The high-temperature transparent glass-ceramic frit particles (purchased from Quincy Carloby Glaze Company, 80 mesh) are clothed on the body surface through the printing process, and then the glass-ceramic frit made in one layer of embodiment 1 is sprayed Particle fixative, you can get the required adobe. This kind of adobe can be sent into a kiln for firing at 1200°C, and the edges are ground and chamfered to obtain a finished glass-ceramic composite board with uniform distribution and complete ice crystal texture. The brick adobe provided by the invention can avoid adverse effects (such as pinholes, lack of decorative effects, etc.) caused by the negative pressure of the preheating zone on the adsorption of frit particles during firing. It should be noted that the high-temperature transparent glass-ceramics frit particles selected in Example 1-1 spread stably during the sintering process, forming a silver-white ice crystal texture on the green body layer, and the glas...

[0032] Example Group 2 - Effect of Attapulgite Clay Content on the Viscosity of Polyurethane Fixatives

[0033] Components of every 100kg polyurethane fixative: nonionic polyurethane associative thickener (NaeWoiKorea., Ltd. company, model HIRESOL85) 4.3kg, attapulgite clay content is added as shown in Table 2, polyether type GPE defoaming Agent (purchased from Hangzhou Feier Chemical Industry Co., Ltd.) 0.6kg, sodium tripolyphosphate 1.2kg, and the balance is diethylene glycol ether.

[0034] 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 and a glass ceramic frit layer from bottom to top, and further comprises a fixing layer arranged on the surface of the glass ceramic frit layer, the fixing layer is formed by spraying a glass ceramic frit particle fixing agent, 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. 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...
