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

[0024] The components of each 100kg frit granule binder: hydroxyethyl cellulose (purchased by Guangzhou Moke Building Material Technology Co., Ltd.) 5.5kg, white carbon black 2.5kg, polymethylsiloxane 1.1kg, silicone modified phosphoric acid Sodium is 1.7kg, the balance is water.

[0025] The preparation method of the above-mentioned frit particle binder includes the following steps: a) dissolving hydroxyethyl cellulose in water and stirring uniformly; b) adding polymethylsiloxane and organic silicon-modified sodium phosphate, and stirring uniformly; c) Add white carbon black and remaining water solvent, stir evenly to obtain frit granule binder, and measure its flow rate to be 25.7s (30°C, 4 cups). It should be noted that the silicone modified sodium phosphate can be replaced by sodium polyacrylate or sodium hexametaphosphate as a dispersant, and this solution can also be realized.

Embodiment 2

[0046] The preparation method of this embodiment is basically the same as that of Embodiment 1, except that the components and ratios used in this embodiment are different. The components of each 100kg frit granule binder: hydroxyethyl methylcellulose (Dezhou Kangrong Chemical Co., Ltd.) 6.5kg, white carbon black 3.2kg, polymethylsiloxane 1.4kg, sodium hexametaphosphate 2.1 kg, the balance is ethanol.

Embodiment 2-1

[0048] Add 375kg silver white ice crystal glass frit particles (purchased from Quincy Carrobie Glaze Company, fineness 100-150 mesh) into 125kg frit particle binder prepared in Example 2, and mix Evenly, a suspension of glass-ceramic frit particles is obtained. The solid content of the glass-ceramic frit particles is 70%, no visible bubbles, and the flow rate is 43.6s (30℃, coated with 4 cups). There is no delamination after the suspension is placed for 5 days Phenomenon, it can be seen that the frit particle binder of the present invention and the glass-ceramic frit particles still have good stability after being mixed. It should be noted that the silver-white ice crystal glass frit particles selected in this embodiment 2-1 spread during the sintering process to form silver-white ice crystal flowers on the surface glaze layer. The glass-ceramic frit particles It can be purchased through the color glaze company, and similar frit products can also realize this scheme.

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: 5.5-6.5% of cellulose thickener, 2.5-3.2% of white carbon black, 1.1-1.4% of defoaming agent, 1.2-1.8% of dispersing agent and the balance of solvent. By using the green brick, 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 building ceramics, in particular to a brick blank for firing a glass-ceramic composite board at one time. Background technique [0002] Since the mature application of glass-ceramic composite board technology, its process technology has continued to develop and innovate, and the product has become a high-end decorative material in the market due to its transparent microcrystalline frit particle personalized decorative effect, and is well received by consumers favorite. [0003] The bricks of the once-fired glass-ceramic composite board include the body layer and the glass-ceramic frit layer from bottom to top. The glass-ceramic frit layer is generally composed of glass-ceramic frit particles. Specifically, the ceramic powder The material is pressed to form a brick, and then a layer of glass-ceramic frit particles is placed on the surface to form a glass-ceramic frit layer to obtain a brick. Then send the above...
