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

[0031] Components of each 100kg of glass-ceramic frit particle fixative: 5.5kg of hydroxyethyl cellulose (purchased by Guangzhou Moke Building Materials Technology Co., Ltd.), 2.5kg of white carbon black, 1.1kg of polymethylsiloxane, silicone modified Sodium phosphate 1.7kg, the balance is ethylene glycol.

[0032] The preparation method of the above-mentioned frit particle binder comprises the following steps: a) dissolving hydroxyethyl cellulose in ethylene glycol and stirring evenly; b) adding polymethylsiloxane and organosilicon-modified sodium phosphate, Stir evenly; c) Add white carbon black and the remaining ethylene glycol solvent, stir evenly to obtain a frit particle binder, and measure its flow rate to be 26.8s (30°C, coat -4 cups). It should be noted that the organosilicon-modified sodium phosphate can be replaced by sodium polyacrylate or sodium hexametaphosphate as a dispersant, and this solution can also be realized.

Embodiment 1-1

[0034] A method for preparing a once-fired transparent glass-ceramic composite board, comprising the following steps:

[0035] A. Green body stamping and forming: After the green body powder (fineness is 150 degrees) and micropowder powder (fineness is 150 degrees) are layered, punched into a green body with a bottom blank layer and a micropowder layer, wherein the micropowder layer The thickness is 1 / 2 of the bottom base layer thickness, dry;

[0036] B. Spray a layer of water-repellent layer 2: Spray a layer of silicone water-repellent on the surface of the green body;

[0037] C, applying glass-ceramic frit particle suspension: the glass-ceramic frit particle of 375kg silver-white ice crystal effect (purchasing from Quincy Carloby glaze company, fineness 100 orders) is added 125kg that embodiment 1 makes In the frit particle binder, mix evenly to get glass-ceramic frit particle suspension, the solid content of glass-ceramic frit particles is 75%, no visible bubbles, and th...

Embodiment 1-2

[0042] A method for preparing a once-fired transparent glass-ceramic composite board, comprising the following steps:

[0043] A. Green body stamping and forming: After the green body powder (fineness is 150 degrees) and micropowder powder (fineness is 150 degrees) are layered, punched into a green body with a bottom blank layer and a micropowder layer, wherein the micropowder layer The thickness is 1 / 2 of the bottom base layer thickness, dry;

[0044] B, applying glass-ceramic frit: the glass-ceramic frit particle of 375kg silver-white ice crystal effect (purchasing from Quincy Carroby Glaze Company, fineness 100 orders) is added the frit of 125kg that embodiment 1 makes In the granular binder, mix evenly to obtain a suspension of glass-ceramic frit particles. The solid content of glass-ceramic frit particles is 84%, no visible bubbles, and the flow rate is 42.5s (30°C, coated with -4 cups). There is still no delamination phenomenon after being placed for 5 days, which shows...

Abstract

The invention relates to a green brick of a monofired glass ceramic composite plate. The green brick comprises a green body layer and a glass ceramic frit layer from bottom to top, a water repellent layer is further arranged between the green body layer and the glass ceramic frit layer, and the glass ceramic frit layer is formed in the way that a glass ceramic frit particle suspension liquid formed by mixing glass ceramic frit particles and a frit particle adhesive is applied to the surface of the water repellent layer; the frit particle adhesive comprises the following components by mass percent: 5.5-6.5 percent of a nonionic polyurethane associative thickener, 2.5-3.2 percent of silica, 1-1.4 percent of a defoamer, 1.2-1.8 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 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...
